Frequently Asked Questions About HVAC Systems

What is the average life expectancy of equipment?

Most heating or cooling units will last about 10 to 20 years. You will notice your equipment will lose efficiency as it gets older, making noises and needing more frequent repairs. You could continue having the old unit serviced, though it may be cost-effective to install a more efficient, newer model. We can help you make the right decision to help your home’s efficiency and keep money in your pocket.

Can I just replace the outdoor unit on an older system to save money?

No. If you only replace the outdoor unit, it will have a negative effect on the unit as a whole, hurting it by up to 15%. This could also cause your unit to fail more quickly while also voiding the manufacturer’s warranty. This is why you should always replace the indoor cooling coil with your outdoor unit.

Will a bigger sized system perform better?

While a bigger air conditioner will cool your home faster, it will not remove the humidity as adequately. With these short run cycles, water and moisture can build up, leading to potential mold and mildew problems. These cycles will also start and stop more often, using more energy and causing a lot more wear and tear.

This also goes for your heating systems. You should let us help you find the right-sized unit for your home for safety, efficiency, and dependable performance.

Why is a system with matched components so important?

There are a number of reasons a matched system is important. Properly sized components will help keep your home comfortable for the humidity control and efficiency you need. This will save you money in the long run while also helping the environment.

How often should I change my air filter?

You should change the air filters in your furnace on a regular basis to keep the air flowing properly and make sure it won’t have to work harder than necessary to maintain a comfortable temperature. Our experts can help you find the right system for your living space.

Why should I switch to a high-efficiency air filter?

High-efficiency filters will remove more dust, pollen, and other particles from the air for better air quality while improving the efficiency of the system. These filters still need to be changed regularly.

Should I have my furnace and air conditioner serviced every year?

In order to make sure your system works properly while also controlling energy and repair costs, it’s important that your system is maintained yearly. This will also prevent major repair expenses from breakdowns.

Why should I purchase a service agreement?

If you don’t have warranty coverage, you could have to deal with a significant repair bill with expensive parts and labor. There is no guarantee that the warranty will cover every possible problem, but our experts can explain the services agreements available for you.

How can I reduce allergens and improve the air quality in my home?

A high efficiency air cleaner can remove up to 99% of pollen, spores, and other allergens, making the air you breathe much safer and helping reduce the number of trips you need to make to the doctor’s office. You can also use a whole home humidifier to reduce itchy skin, scratchy throats, and static electricity associated with dry air.

I am concerned about mold growth; what should I do?

When water collects in the drip pan and becomes stagnant, the pan can grow mold, which can infect your home with dangerous spores. Once these spores get into your HVAC system, they can remain there and continue to grow.

You can do three things to prevent mold growth in your system:
  1. Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog free.  
  2. Install ultra violet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan.  
  3. Keep your ductwork clean by using our duct cleaning service, and use a high-efficiency filtration system to keep your entire HVAC system clean. 

What do SEER, AFUE, and HSPF ratings mean to me?

SEER, AFUE and HSPF are all measures of energy efficiency. Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER) can vary widely. Higher SEER numbers save more money on electricity. A 13 SEER air conditioner, the EPA "current minimum standard," uses 23% less energy than a 10 SEER unit (EPA standard until Jan. 2006). Depending on your average usage, higher SEER air conditioners can significantly reduce your electric bill.

Heat pumps have SEER ratings and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher HSPF ratings mean greater energy savings. The HSPF scale range is 7.5 to 13.0.

Today's new high-efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that was sold in the United States until May 1, 2013 is 80% in southern states and 90% in northern states.

How can I reduce my energy costs?

Cooling
  • Upgrade to a High-Efficiency Air Conditioner – Installing a new high-efficiency AC unit can cut your electricity bills by one third. 
  • Turn up the Temperature – You can save 3 to 5% off your energy bill for every degree higher you set your thermostat, with 75° being the optimum level. 
  • Install Ceiling Fans – During the summer, you should operate your ceiling fan in a counter-clockwise direction for a gentle breeze.
  • Have an Annual Maintenance Performed – A licensed technician will make sure your unit runs at peak performance and catch any breakdowns before they occur. 
  • Don't Block Vents in Well-Used Rooms – Blinds, carpets, furniture, and such should be kept away from vents to keep your AC operating efficiently for even cooler air distribution. 

Heating
  • Upgrade to a High-Efficiency Furnace – Using up to 50% less fuel than older systems and saving as much as 25% off your home heating costs, a new furnace allows you to recover the initial cost of replacing or upgrading the unit in a few years.
  • Have Annual Maintenance Performed – With yearly maintenance performed on your furnace, a licensed technician will make sure your unit will operate efficiently and ensure any issues are caught before they become major problems. 
  • Install a Programmable Thermostat – You can control your home temperature when you are away or asleep, saving 1% on your heating bill for every 1° per seven hours a day.
  • Don't Block Vents in Well-Used Rooms – You can have an even heat distribution by keeping supply and return air vents free from blinds, carpets, and furniture. 
  • Install Ceiling Fans – During winter months, the fan’s blades should be run in a clockwise direction to push the warm air down into the room. 

Why should I buy ENERGY STAR labeled equipment?

Proper sizing, quality installation and maintenance, and other considerations can help you get the most out of your heating and cooling unit, saving you as much as 20% on your total energy costs.

ENERGY STAR qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE).

What is a heat pump?

Heat pumps are efficient alternatives to electric heat, running as a heater in the winter and running in reverse in the summer. The system is backed up by another heating source, usually electric heat, for extremely cold winter days.

What is a hybrid heat dual fuel system?

A hybrid heat system combines intelligent control for both gas and electric heating, giving you an intuitive system that can react when the conditions change. The outside temperature, regardless of how warm or cold, will cause the hybrid system to select the most efficient heat source automatically.

What is a geothermal system?

Depending on the geographic locations, the Earth maintains a constant temperature of about 50° to 70° by absorbing nearly 50% of all solar energy. A geothermal unit will heat and cool your home using this constant temperature, giving you up to 60% savings versus traditional systems. A single compact unit can give you heating, air conditioning, and hot water with no fuel, no odor, and no loud equipment.

What are the advantages of equipment with variable speed fans?

Variable speed fans spin at different speeds depending on the heating and cooling needs of your home. They usually operate at lower speeds for a steady stream of warm or cool air, helping control humidity, utility costs, and system noise. The fan will increase in speed to meet your comfort needs on the hottest and coldest of days.

How does 2-stage heating or cooling work?

The 2-stage cooling method can manage your home temperature while temperatures change, maximizing comfort and energy efficiency. 2-stage cooling can be done by having a small and large compressor, with the smaller putting out about 50% the capacity of the larger one.

You can also have 2-stage cooling with a single scroll unloading compressor that can unload its capacity to 66% of capacity. Both of these methods help save energy by running at a lower stage when the higher stage is unnecessary.

2-stage heating works on the same principle as 2-stage cooling, allowing the unit to adjust itself based on the amount of heating necessary.

A heat pump system would have a small and large compressor, which would run depending on the needs, using the larger one only when a high amount of heat is needed.

With a modulating gas valve that regulates gas flow depending on need, a stage 2 gas furnace can also help save you money.

At what temperature should I set my thermostat?

For cooling purposes, you should set the thermostat at 75° to 80°, with proper heating set between 68° to 72° for proper comfort and maximized efficiency.

My system doesn't work well in a couple of rooms. What should I do?

There a many things that can cause this, including uneven solar heat through windows, a system that is too small, a clogged system, and more. Our experts can figure out the problem and offer you a solution.

Is Freon as a refrigerant being discontinued?

As of January 2010, the refrigerant R-22 (what consumers call Freon®) is no longer allowed to be used in the manufacturing of new equipment. All air conditioners and heat pumps now use R-410A, which is a more "environmentally sound" refrigerant.

The most commonly used refrigerant in existing residential AC units R-22, though there have been caps put on the production of it, which will cause its price to skyrocket.

Can carbon monoxide build up in my home?

Carbon based fuels like gas, oil, kerosene, or wood produce gases, including carbon monoxide can all build up in your home. It is advised by the CPSC to install carbon monoxide detectors to alert you of the presence of this toxic gas. If you and your family wake up with a headache, you should get out of the house and seek medical help quickly.

What if I smell gas?

Propane (LP) gas: If you have this type of gas, then you will have a tank located outside your house. Propane expands when changing from liquid to vapor, making it especially dangerous in a confined space. Propane contains a chemical odorant for a distinct smell which can be found in low spots due to being heavier than the air.

If you smell propane (LP) gas:
  • Exit your home immediately. 
  • Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark. 
  • From a safe area, contact your propane supplier and call 911.  
  • If you are able, shut the propane gas supply off at the tank. 
  • Stay away from your home until you've been told that it is safe to return. 
Natural gas: You have this type of gas, which also contains a chemical odorant, if you have a meter and pay a natural gas supplier or utility.

If you smell natural gas:
  • Exit your home immediately.
  • Do not light a match, start an engine, use a cell phone, or do anything that may create a spark. 
  • From a safe area, contact your gas company and call 911.  
  • If you are able, turn the gas off at the meter. 
  • Stay away from your home until you've been told that it is safe to return.
