Can Duct Seal Be Removed?

Yes, duct seal can be removed, but the process can be labor-intensive and may require professional assistance. The type of sealant used determines the removal method. Mastic sealants, for example, are thicker and may need to be scraped off manually. Tape sealants can often be peeled off but may leave residues that need to be cleaned.

It’s crucial to be cautious during the removal process to avoid damaging the ductwork. Professionals have the tools and expertise to remove the sealant without causing harm to the ducts, ensuring that they are ready for re-sealing or other maintenance.

Can I Seal Ducts Myself?

Sealing ducts yourself is possible, but it comes with several challenges and potential pitfalls. DIY duct sealing can be effective if you have the right materials and knowledge about the process. The steps typically involve locating the leaks, cleaning the area around the leaks, and applying the sealant properly.

However, there are several reasons why hiring a professional for air duct sealing and repair is often the better choice:

1. Proper Diagnosis: Professionals can thoroughly inspect your duct system to identify all leaks and underlying issues that might not be apparent to an untrained eye.
2. Quality Materials: HVAC technicians have access to high-quality, industry-grade sealants that might not be readily available to consumers.
3. Correct Application: Proper application of sealants is crucial for long-lasting results. Professionals are trained to apply sealants in a way that maximizes efficiency and durability.
4. Safety Concerns: Ductwork can be located in difficult-to-reach or hazardous areas, such as attics or crawl spaces. Professionals have the equipment and experience to navigate these spaces safely.

What is the Best Method of Duct Sealing?

Several methods are available for duct sealing, each with its advantages. The best method often depends on the specific conditions of your ductwork and your HVAC system. Here are some of the most effective duct sealing methods:

1. Mastic Sealant: Mastic is a paste-like substance that is applied directly to the leaks in the ductwork. It is highly effective for sealing small gaps and cracks and is known for its durability and flexibility. Mastic is often used in conjunction with fiberglass mesh tape to reinforce the seal on larger gaps.
2. Aerosol-Based Sealant: This method involves spraying an aerosolized sealant into the duct system. The sealant particles adhere to the edges of leaks and gradually build up to seal the gaps. This method is particularly effective for sealing leaks in inaccessible parts of the duct system.
3. Metal Tape: Specially designed for HVAC systems, metal tape is a highly adhesive and durable option for sealing duct leaks. It is especially useful for sealing joints and seams in metal ducts.
4. Duct Tape: Contrary to its name, traditional duct tape is not recommended for sealing ducts. However, there are HVAC-specific tapes, like aluminum foil tape, that are effective for sealing minor leaks and joints.

Benefits of Professional Air Duct Sealing and Repair

Professional air duct sealing and repair offer numerous benefits that go beyond simply stopping leaks. These include:

• Improved Energy Efficiency: Properly sealed ducts reduce energy loss, leading to lower utility bills.
• Enhanced Comfort: Even air distribution throughout your home results in more consistent temperatures.
• Better Indoor Air Quality: Sealed ducts prevent dust, allergens, and pollutants from entering the HVAC system and circulating through your home.
• Extended HVAC Lifespan: Efficient ductwork reduces strain on your HVAC system, potentially extending its lifespan.

Why is my central air conditioner not cooling?

As the summer progressed, you may have noticed that the central air conditioning system wasn’t cooling your home, there can be several issues that cause that. On your end, first, check the thermostat was set to “auto” and “cool”.  Then check the air filter and change it or clean it. If all is in proper condition and your home still isn’t cool, it is time to schedule a central air conditioning repair service. 

What is the life expectancy of a central air conditioner?

The average lifespan you can expect from a central air conditioning system is around 15 years, some may last 30 years and others may quit at 8 years.   There are some factors that can affect the average lifespan such as: 

• The quality of the HVAC system 
• The quality of the installation
• The amount of usage 
• The maintenance and upkeep
• The insulation level in your attic

How do you clean a clogged condenser coil?

The exterior component of your central air conditioning system is important for the system to properly cool. Here are the basic steps: 

1. Turn off the power to the air conditioner.
2. Remove the top and side covers of the condenser unit.
3. Remove the fan if you can and want to try.
4. Clean off any debris in and around the unit
5. Vacuum over the coils to remove any dirt and dust.
6. Fix any bent fins.
7. Spray a coil cleaner over the coils.
8. Using a garden hose, spray water over the coils to complete the cleaning.
9. Put the air conditioning unit back together.

Go inside the house and make sure the thermostat is in “cool” and “auto” positions and set it 10 degrees lower than the house is currently. After an hour, if it hasn’t cooled the house to the set temperature, call for a professional central air conditioning repair service.

How do you know if the compressor is the problem with your central air conditioning? 

There are some indicators that hint that the compressor in your central air conditioning may be going out. However, these same symptoms can be something else: 

1. Strange sounds from the outside component.
2. The air conditioning system overheats.
3. Warm air blowing from the vent.
4. Refrigerant level is low.
5. Moisture leaking from the system.
6. Energy bills have skyrocketed higher than normal.

What are the most common furnace repairs?

Whether you wake up in the middle of the night, early in the morning, or come home after work, you don’t want to walk into a cold house on a winter day. Even here in Orange, California, winter can have a chilly nip to the air! That’s why having your furnace repaired well before the winter months settle in is a good idea. 

Some of the most common gas furnace repairs that HVAC technicians do are:

1. The Air Filter

This would rank number one and is something a homeowner could do themselves! Changing or cleaning the air filter is a must year-round, no matter the weather! When the filter is clogged and dirty, it stops the air from flowing through the vents throughout the house. It isn’t uncommon for a gas furnace to shut down completely when the filter is too clogged. You can avoid a gas furnace repair service call by changing the filter every 30 days.

2. The Thermostat

Technicians often find the gas furnace repair needed is the thermostat. This device communicates to the furnace when to turn on and off and how warm it is to heat the house. A malfunctioning thermostat can keep the heat off and the house cold. Or it may work sporadically, referred to as short cycling, and your home can’t get warm or stay warm. 

3. The Ignition 

The ignition is an essential component as it works the pilot light. This gets its signal from the thermostat, telling it when to cut on or off. Without a pilot light, a gas furnace can’t operate. If you have checked that the pilot light is on and still don’t get any heat, you’ll need to schedule a gas furnace repair service.

4. Wear And Tear

Nothing will last forever, including a gas furnace. A furnace goes through many cycles over the years, taking a toll on the components. When gas furnace repairs cost more than 25% of a new furnace, it is time to replace it. 

5. Poor Maintenance and Upkeep

Just like a car, a gas furnace requires a certain level of maintenance and upkeep. Where your car gets oil changes, tire rotations, and inspections, a gas furnace needs the filter changed or cleaned regularly, the components cleaned, adjusted, and sometimes upgraded. A regular inspection by an HVAC professional that includes cleaning, lubricating, and calibrating the furnace will minimize the need for frequent gas furnace repairs. 

What component fails the most on gas furnaces?

The ignitor and pilot light cause most gas furnace repair calls, but fortunately, depending on the age and brand of the furnace, the parts are typically readily available at a nominal cost. 

What is the most expensive part to fix on a furnace?

Speaking of costs, when it comes to gas furnace repairs, the most expensive part that needs repairing or replacing is one of the following: 

• The blower motor at an average cost of $2,000 or more
• The heat exchange at an average cost of $1,500 or more
• The draft inducer motor at an average cost of $1,500 or more

These are only average guesses for the costs of these components. The actual price can vary based on the age and brand of the gas furnace and the upcharge by the HVAC technician. These prices do not include the labor that somebody will add to your gas furnace repair bill. 

What are the most common reasons a gas furnace may stop working?

The most common problem that gas furnace repair technicians encounter is a dirty or clogged air filter. Other issues they may see include debris, dirt, furniture, rugs, and other objects blocking the furnace’s airflow. This can cause the furnace to overheat and shut down. It would help if you kept a 6-foot distance between furniture, other objects, and the furnace and vents. 

What is the life expectancy of a gas furnace?

Several factors can determine a gas furnace’s lifespan. The brand and installation are vital factors, followed by maintenance and upkeep. Maintenance and upkeep also include getting gas furnace repairs done when needed. The longer you delay, the more damage could happen. The average lifespan is between 15 and 30 years; on rare occasions, some have lasted 40 years. 

For Keeping Warm

Here are five reasons why you should call for a gas furnace repair service: 

• Your furnace doesn’t turn on
• Odd sounds are coming from the furnace 
• The thermostat isn’t responding
• The furnace is overheating
• Odd odors are coming from the furnace

If you’re ready to repair your furnace, our team can help. We offer furnace repair in Orange, CA so call us at (714) 464-6622 to schedule your service.

Are commercial and residential AC systems different? 

No, while they have the same goal, keeping the interior comfortable, a commercial AC system is more complex, mostly because it is larger. A commercial unit requires more power and typically has several zones to treat, spread over more area. As such, commercial AC contractors have additional training than residential AC contractors. Other differences between residential and commercial AC systems include:

• The placement of the unit. In a home, there is a component inside the house, typically in a closet, and an exterior unit just outside of the home. Most commercial AC systems are installed on the roof for a variety of reasons, such as the noise and the amount of space needed that would take up valuable parking space. 
• The drainage system of a commercial AC unit for the moisture that accumulates while operating. For a residential system, there is a drain line and drain pan. A commercial AC system, because it is larger, will have multiple drain lines that should be inspected by a commercial AC contractor regularly.
• The energy use of a commercial system is more than a residential unit. A commercial AC contractor can usually handle the electric wiring, but they may need to bring in a professional electrician if the wiring and connection are complicated. 

What type of maintenance does a commercial HVAC system require? 

No matter what type of HVAC system your commercial or industrial structure has, it will require maintenance to keep it functioning. That maintenance should be on a routine schedule that includes the following tasks, some your own maintenance team can do, and others will need to be done by a commercial AC contractor: 

• Air Filters: Inspect and Clean

This is a simple step that will have a significant impact on the system’s energy efficiency and indoor air quality. 

• Thermostat: Calibration

Calibration of the thermostat will keep the interior temperature consistent which eases the energy consumption. 

• Electrical Components: Inspected

This should be done by a professional commercial AC contractor. They are trained and have the proper tools to inspect and repair if needed the electrical connections, terminals, and wiring.

• All Moving Parts

Again, this is best when done by a professional commercial AC contractor. They will inspect, clean, and lubricate all moving parts like bearings and motors. Keeping these lubricated will extend the lifespan of the system. 

• The Coils: Inspect and Clean

Your maintenance team can do this each month, and once a year have a commercial AC contractor inspect the evaporator and condenser coils. They will clean off any accumulated debris and dirt that can hamper the heat exchange and reduce the system’s efficiency.

• Drainage Lines and Drain Pans

A commercial AC contractor will inspect the drain lines and drain pans, cleaning or replacing them as necessary. 

• Refrigerant Levels Checked

When the refrigerant levels are low, the compressor can be damaged as the system tries to operate. If the refrigerant is low, this will require a professional commercial AC contractor to add more.

• Blower Components: Inspect and Calibrated

The blower assembly is what distributes the conditioned air throughout the commercial structure. A professional commercial AC contactor will have the tools needed to thoroughly inspect them and calibrate them to keep them in proper working order.

Additional Steps

With an annual visit by a commercial AC contractor, they will also inspect the air duct system for any blockages or leaks. They will then test the system to ensure it is functioning correctly. 

What are indicators your compressor isn’t working correctly? 

The compressor is a vital part of any commercial AC system, and if you notice any of the following, contact a commercial AC contractor immediately: 

• Strange sounds: If you hear any clicking, grinding, or rattling sounds coming from the AC system, it often is because the compressor motor is worn out. It can also indicate that there are bat capacitors or relays. Any of these things will need the attention of a commercial AC contractor. 
• Leaking condenser: If you notice puddles around the condenser, it may be a refrigerant leak, requiring inspection by a commercial AC contractor. 
• AC isn’t cooling adequately: If the air conditioning isn’t keeping the interior of the structure cool, it can be a few different things. A commercial AC contractor will check the thermostats first throughout the structure, then all the vents. If all seems in good working order, they’ll check the compressor and the refrigerant level next. 
• Slow to start: If the compressor appears to be struggling to get started, it should be checked by a professional commercial AC contractor. 
• Circuit breaker tripping: If the circuit breakers keep tripping when the air conditioner starts, this needs to be inspected by a professional commercial AC contractor. 

In Closing 

It is highly recommended to have a commercial AC contractor inspect the system annually. During the inspection, they will inspect the entire system and keep things clean and lubricated as needed. These annual inspections will keep the system in top condition and minimize any emergency service calls while extending the lifespan. If you need a commercial ac contractor in Orange, CA, please get in touch with us at (714) 464-6622.

What type of coolant do HVAC systems need?

HVAC systems require a coolant that is referred to as a refrigerant. In the past, that refrigerant was R-22 called Freon. After much study and research, the contents of R-22 were discovered to be harmful to the environment, and a new refrigerant was introduced, Puron or R410A.  R-22 has slowly been eliminated over the past 10 years or so, and R410A is the only refrigerant readily available.  

Freon and Puron are both registered trade names for these refrigerant products.  Other brand names for the Puron refrigerant are EcoFluor, Forane, or Suva.

What does this refrigerant do in an HVAC system? 

R410A, like R-22, is a low-pressure gas that is superheated. It is injected into an HVAC system by the technician and enters the compressor. The compressor pumps the low-pressured gas towards the condenser, where it is cooled and condensed. The cooled air is distributed throughout the air duct system and out vents in each room.

At this point it becomes a vapor, then becomes a cool liquid with high pressure, creating hot air. That hot air is pushed into the exterior component of an HVAC system and blown out into the atmosphere. 

How often should coolant be added to AC?

The process described above will use that gas refrigerant product over time, lowering the amount of the gas-type product inside the system. This requires an AC coolant refill service on an average of every five years, which has to be done by a licensed, professional HVAC technician.  If an HVAC system requires an AC coolant refill more frequently, it is usually because of a leak. 

Can a homeowner do their AC coolant refill process?

Yes, but it isn’t recommended because the coolant is a gas substance that is under high pressure. Many videos online make an AC coolant refill seem easy, but without the proper tools and the technical knowledge that is needed, it puts the person, and the HVAC system at risk. 

How much does an AC coolant refill service cost?

Because Puron, as the other brands, can only be purchased by certified, licensed professionals, it is expensive and is priced by the pound. On average, an AC coolant refill service call can cost as much as $300 or more. Like any business, professional AC service companies will have various rates. Some may charge by the pound of AC coolant refilled in the system plus a labor fee. Others may have a flat rate, which the final cost will come out about the same. 

Are Freon and Puron the same?

No, even though Freon, the R-22 version, and Puron, the R410A version go through the same process within an HVAC system, they are different. The R410A product is more environmentally friendly. It is a chlorine-free substance that doesn’t deplete the ozone as the R-22 product does.  

With the concerns of the environment around the world, especially in heavily populated areas like Orange County, California, the R-22 is no longer manufactured to help the environment. As such, many homeowners have to replace their existing HVAC system because the R-22 product isn’t as readily available. 

Can R410A be used instead of R-22? 

No, the two refrigerants have different chemical properties with the R410-A being a higher pressured refrigerant. If a technician (or homeowner) were to use the R410-A for an AC coolant refill job, it puts a risk of the entire HVAC system rupturing. This can harm the person performing the AC coolant refill job as well as the home. 

What are some indications an HVAC system needs an AC coolant refill? 

The AC coolant doesn’t have a dipstick like a vehicle’s oil or a gauge like the gasoline. But the following are indications that an HVAC system should be inspected by a professional and could need an AC coolant refill: 

• The air conditioner constantly runs but isn’t cooling the home.
• Nothing but warm air is coming through the air vents.
• The electric bills have significantly increased.
• There is ice built up on the refrigerant line.
• You hear a bubbling or hissing sound coming from the refrigerant line.

In Closing 

If you have noticed any of the five indications we just listed with your HVAC system, check the air filter first. If you haven’t changed or cleaned it every 30 days as recommended could be the cause.

If the filter has been changed or cleaned, call a professional HVAC service company. They will inspect and test the HVAC system and if needed, perform an AC coolant refill service. If you need an ac coolant refill in Orange, CA, you can count on us to help! Give us a call at (714) 464-6622 now!

How bad is the outdoor air quality in California? 

It is apparent what affects our outdoor air quality, starting with vehicle emissions, creating up to 40% of the pollution. This is primarily in Los Angeles and the surrounding area there is more than one car per person.  Other contributions to the decline in outdoor air quality here in California are the wildfires, heat waves, and energy sources. 

What are the contributing factors affecting indoor air quality? 

The majority of pollutants that affect indoor air quality come from sources inside our homes and businesses, such as the outdoor climate and the weather conditions, along with human behavior. 

 The weather conditions can cause occupants to keep the windows closed or open. Then when it’s hot, we turn on the air conditioner and when it’s cold, we turn on the heaters and humidifiers. Each of these affects the indoor air quality in our homes, offices, and businesses. 

But there are other contributing factors to harming the indoor air quality: 

• Combustion Byproducts: Carbon Monoxide, Particulate Matter, Tobacco smoke.
• Natural Substances: Mildew, Mold, Pet Dander, Radon.
• Biological Agents: Molds.
• Asbestos, Lead, and Pesticides.
• Ozone from Air Cleaners.
• Various VOCs (volatile organic compounds).

What is considered to be a safe indoor air quality level?

Every day, the EPA (Environmental Protection Agency) analyzes the air pollutants in different locations, breaking them down into 5 groups and how they affect the AQI (Air Quality Index), both indoor air quality and outdoor air quality. 

Ideal indoor air quality as determined by the EPA is under 100. For anything over 100, caution is advised. However, people with existing health issues can have difficulty breathing with an indoor air quality that has an AQI measuring over 51. 

What are the symptoms of poor indoor air quality?

We come home with the feeling that we’re safe and protected. But when it comes to indoor air quality, are we safe and protected? Unfortunately, there are unseen dangers in the air that can make you and your family sick. Some of those dangers include: 

1. Respiratory Issues

If anyone in your home suffers from allergies and other respiratory irritations, this should be an alarming sign that the indoor air quality in your home is not healthy.  Any excessive breathing issues, coughing or sneezing are justifications to have your home’s air quality inspected. 

2. Frequent Headaches

Any person in your home that has frequent headaches can be an indication of poor indoor air quality. There is a wide range of possibilities contributing to this, like VOCs and inadequate air circulation.

3. Fatigue and Insomnia

Poor indoor air quality can make it difficult to get a good, solid night’s sleep. With airborne irritants like dust and pollen, breathing becomes difficult, makes us restless, and falling asleep becomes difficult, only to wake up and have difficulty falling back to sleep. 

4. Excessive Dust 

Yes, all homes will have dust, but if you seem to be constantly wiping that dust off surfaces around your home, you should change the air filter. If that doesn’t help, have your air ducts cleaned and inspected. 

5. Energy Bills Increase

Poor indoor air quality can cause energy bills to increase because the HVAC system is working harder. Have an indoor air quality test performed and this can help determine the exact problem. 

6. Unpleasant Smells

Another indication of poor indoor air quality is persistent unpleasant odors and smells. From a musty smell to a chemical odor, they can be caused by mildew, mold, and other pollutants.

Another indication that your home or business has poor indoor air quality is a high humidity level inside. The humidity should never be more than 50% inside. Condensation on glass surfaces is often caused by poor ventilation, affecting the indoor air quality, and the combination of humidity and condensation can lead to mildew and mold growth, resulting in the air feeling and smelling stale. 

Clearing The Air

So, how can you improve your home or business’s indoor air quality?  Well, first don’t worry that a major investment may not be necessary!  There are three steps you can take that are inexpensive, even free to get better indoor air quality. Those three steps are: 

• Control the source of the problem: Simply eliminate any individual sources of pollution like sealing or removing any asbestos, make sure gas appliances are connected and functioning properly, and increase the ventilation in the attic. 
• Have adequate indoor ventilation: Most HVAC systems do not pull in fresh air. When the weather permits, opening doors and windows, and turning on attic fans, the bathroom and kitchen exhaust fans will increase the outdoor ventilation and improve the indoor air quality. 
• Change or clean air filters: This should be done every 30 days and if there are any occupants with respiratory issues, more frequent can help the indoor air quality. 

What are common signs of an air conditioner in need of emergency repair? 

So, it’s hot in your home, and the air conditioning apparently isn’t working. How do you know if it is a simple problem, like changing the air filter, or if it is an emergency air conditioner repair? The following 6 situations would constitute you have an emergency air conditioner repair: 

• Unusual noises and sounds: This is the top reason to call for an emergency air conditioner repair service call. Odd noises and sounds are an indication that a component inside the system is damaged, and if the air conditioner keeps running, you may be replacing the entire system. 
• Warm or hot air: If the airflow coming from the vents is warm, or worse, it’s hot, this is often due to blockage of the airflow. If you change or clean the air filter and making sure the intake isn’t blocked doesn’t help, you need to turn the system off and make an emergency air conditioner repair service call.
• Ice formation: If you’re seeing water puddling on the floor around the air conditioner system or ice inside the system, specifically on the evaporator coil. Turn the system off for an hour, try it again, and if the ice forms again, make that emergency air conditioner repair service call. 
• Electrical occurrences: If the circuit breaker trips unexpectedly while the air conditioner is cycling, you need an emergency air conditioner repair service technician to check the electrical components. Unaddressed, it could create a fire hazard.
• Odors: If you smell electrical or melting plastic, this can indicate something is not working correctly within the system, this is definitely an indication you need an emergency air conditioner repair service call.

How do you troubleshoot an air conditioner before calling for emergency air conditioner repair? 

Well, it depends on the problem you’re having.  If there isn’t any air coming from the vents, check the air filter. Changing or cleaning could be the fix. If the air is warm coming from the vents, check the thermostat is in the COOL and AUTO position. If not, make the adjustment and see if that cools the air. 

If the system is shutting down completely, check the breaker box or circuit breakers and if they are in the off position, flip them back on and try the system again. If these steps don’t fix the problem, make that emergency air conditioner repair service call. In both of these situations, check the outdoor component and make sure nothing is sucked up the unit. This can block airflow and cause it to blow warm air or shut the system off at the breaker. 

How long does it take for the emergency air conditioner repair technician to arrive? 

This can vary from company to company, and if there is a major heatwave across Vacaville, California. Most emergency air conditioner repair technicians arrive within an hour. Keep in mind that emergency air conditioner repair service calls will cost more when they are after hours, on a holiday, or on the weekend. If you can use fans to keep cool until normal business hours, the service call won’t cost as much. 

In The Heat of the Moment …. 

Once the emergency air conditioner repair technician arrives, they will ask what problem you’re having to give them a general idea. They will check the basics first like the air filter, the air vents, the drip pan and drip tube, and the outdoor component. 

If they don’t find a problem, they will open up the system and inspect the interior guts like belts, fans, etc. They will grease or oil as needed, check the refrigerant level, and other moving parts, making repairs if needed. 

Once they have completed their inspection, they will discuss what they found with you and make suggestions as to what repairs are needed or if the system needs to be replaced. If they are recommending a replacement, you should call for 2 or 3 quotes for a new unit and ask what type of warranty each company offers. While the first emergency air conditioner repair technician may be your knight in shining armor at the moment, you don’t need to make that type of decision in the heat of the moment.

What is the Thermostat Used For?

A thermostat is a device or an instrument that maintains the temperature within given limits. It turns the air conditioning or heating off when the set temperature is reached. 

There are different types of thermostats, such as the one you use for roasting that Thanksgiving Turkey, or the one in your car that tells you that it’s overheating. 

But in this article, we’re going to focus on the different types of thermostats available for homes.

What are The Different Types of Thermostats for the Home?

There are four types of thermostats used in homes today. They can range in pricing from very inexpensive to very expensive, with each one having a different level of energy efficiency. Those four basic types of thermostats are: 

• Non-Programmable 

If you’re home more than you’re not, a non-programmable thermostat is a perfect thermostat for your home. The temperature is adjusted manually to your ideal preference. This is the most basic of thermostats.  

• Programmable 

A programmable thermostat allows you the ability to pre-program the temperature based on when you’re home and at night. These thermostats can be set for each day of the week, and this saves the air conditioning or heating from working when you’re not there, decreasing the wear and tear of the thermostat, reducing your energy bills, and minimizing the need for HVAC  repairs.

• Wi-Fi 

If you have a computer, smartphone, or tablet, you probably have other devices connected for wireless control. The thermostat in your home can be connected with these types of thermostats so you can access it via a wireless network. This enables the ability to adjust the temperature while you’re away, even overriding the programmed setting if desired. 

• Smart 

The smart thermostat integrates with other automation tools and equipment in your home, learning your lifestyle habits, then adjusting the temperature accordingly. It recognizes your family’s patterns and stores that information to provide maximum efficiency with your cooling and heating.

A commonly asked question about home thermostats is, “Should I leave the thermostat at a constant temperature?”, and the answer to that may surprise you!

No! By leaving your thermostat at a constant temperature 24/7/365, it is wasting energy and money and wearing the HVAC system out sooner than needed.  

The thermostat should be adjusted down or up according to the weather.  The excerpts at Energy Star recommend setting the thermostat between 70 degrees and 78 degrees, then raising it another 8 degrees when you’re not going to be home. 

How Much Money Will a New Thermostat Save Me? 

This is another commonly asked question because most of us think, “If it’s working, leave it alone.”. This makes sense, but what if it isn’t working at full capacity? 

A new thermostat will save you money, but there are other factors that play into this too, such as:

• The age of your HVAC system
• The insulation in your attic
• The age and condition of the windows
• The number of people living in the household
• Where you live and your family’s lifestyle

How Can You Cool or Heat Your Home Without Replacing the Thermostat?

Sometimes, there isn’t any spare money for something like a new thermostat, especially when the current one is working! So, here are a few things you can do to maintain a comfortable level in your home: 

• Seal the drafty areas like doors and windows in the winter to keep the cold out and the heat in.
• In the winter, wear layers even inside the house, and in the winter, wear light colors and fewer layers. 
• Use the ceiling fans! Change the direction they are turning based on the season to help regulate the comfort level in each room.
• Have a professional HVAC inspection performed annually. 
• Change the filter every 30 days.
• Keep the outside component of your HVAC system free of any debris, dirt, and grass that gets sucked up against it. 

Can I Install My Own Thermostat Replacement? 

If you’re a handy DIY homeowner, absolutely! They come with full instructions and there are countless videos online that can walk you through the process. 

Of course, having it done by a professional will ensure that it is done correctly, should have a warranty on the work, and will minimize any chance of something getting shorted out. If you have a regular HVAC technician that does your annual inspections, inquire what they charge to upgrade the current thermostat. 

Keeping It Cozy! 

Your home is an investment and the HVAC system is an investment to that investment. Consider replacing your current thermostat with a newer one as an investment that will provide your ROI with lower utility bills and a comfortable home. 

What is commercial HVAC preventive maintenance?

Preventive maintenance is a strategy for being proactive in keeping the HVAC system in good working order. PM (preventive maintenance) by a professional commercial AC contractor will include routine inspections with selective service and needed repairs to the HVAC equipment at scheduled intervals. 

The objective of having a commercial AC contractor perform this preventive maintenance routine is to extend the life expectancy of the HVAC system and prevent disruptions, and unscheduled downtime and reduce maintenance costs overall by correcting defects and issues at the onset. Some specific types of commercial HVAC preventive maintenance strategies are: 

• Routine Maintenance: Cleaning, inspecting, and servicing is important, and should include changing air filters and other small tasks. This can be done by the building maintenance crew or a professional commercial AC contractor.
• Proactive Replacements: During professional maintenance by a commercial AC contractor, this will include replacing broken, non-working, and worn building components. 
• Scheduled Refurbishment: This service is typically done by schools and other learning institutes during scheduled closings. A commercial AC contractor will inspect all components that have defective and deteriorated components, then repair or replace them as needed. 

Preventive maintenance by a commercial AC contractor on a commercial building is akin to that of oil changes on a vehicle. These measures listed above prevent costly repairs over time while extending the life of the system. This saves money for the company and keeps the HVAC system in a healthy and safe operating mode.
