What Does AFUE Mean?
AFUE stands for annual fuel utilization efficiency. This rating system gives you a quick way to see how cost-effective an HVAC unit is.
Older, lower-tier furnaces typically have an AFUE of 56 to 70 percent. That means little more than half of the fuel they consume gets used. Not exactly the most productive use of resources. Fortunately, furnaces have come a long way since then, burning as high as 98.5 percent AFUE.
How Much Money Can a New Furnace Save You?
Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Just enter your current unit’s AFUE value and compare it to a newer, more efficient system.

Environmentally Friendly
A new furnace does more than save you money on energy costs—it lowers your home’s carbon emissions. Switching out from your old 56 percent AFUE clunker to a 90 percent AFUE efficiency model can reduce your carbon footprint by a significant margin, according to the U.S. Department of Energy (DOE).
What Is a Variable Speed Furnace?
Single-stage furnaces only blow hot air at one speed. They are the most affordable upfront—but the most expensive to operate. Additionally, they have the most temperature variance, sometimes a four to six degrees difference between rooms.
Two-stage furnaces can distribute hot air at a full-speed or half-speed setting. This allows for more comfort and efficiency without breaking the bank.
Variable speed furnaces have fully dynamic and responsive blower speeds. This is the most energy-efficient option by far. Also, your home will be a near-uniform temperature, within a fraction of a difference between all rooms.
How Does a Furnace Work?
Gas furnaces heat using combustion. Once you set your thermostat, your furnace gets to work.
The ignitor lights the gas. Newer models use an electric starter to ignite, while older models use a pilot flame.
The combustion chamber lets in oxygen. This keeps the combustion efficient and clean. It also gets rid of byproducts, sending them through your flue.
The heat exchanger captures the heat rising from the combustion chamber. It has metal tubes that warm up. The heat from the tubes gets distributed through your air ducts with blowers.

“Brian Warren did a great job figuring out that my Y1 had issues. We had an extra wire in the line so he used that one replacing the yellow wire. Double checked the heat exchanger to be sure it was getting a signal. Very thorough and polite.”
– Christopher B.
“Alex came on a service call to fix my gas furnace. He was prompt, polite and very professional. My problem was resolved. I have always been impressed with ESA.”
– patrick r.
“I have been using ESA as my HVAC maintenance company since relocating to MD over two years ago. I have always been impressed with their professional service and knowledgeable staff. ESA notified me of severe rusting problems with my townhouse’s 22-year-old gas furnace following annual inspection. With their help and advice, I chose a new Carrier furnace as a replacement. It was installed in mid-January by a very capable crew. Cody, Dylan and John M did the work on time, cleaned up afterwards and explained the new furnace’s features and operation. I am completely happy with the result and glad to recommend ESA to all concerned.”
– William P.
“Wow! I see why they’re the best in Howard County. Richard ensured we received the best quality service. He was fully transparent about what was and was not needed. Alex did an outstanding job at figuring out what was wrong with the unit. Moreover, they did not leave until it was fixed. Honest, knowledgeable and reliable. I highly recommend their services!
Thanks again!”

“We would like to recognize Nicholas for his outstanding efforts in troubleshooting our recent issue with our furnace thermostat. We called ESA because our thermostat screen would turn “blank” several times a day for several minutes. Initially he thought we would need a new thermostat unit, so a followup appointment was scheduled for the next day for installation. When he returned, he told us he had thought about this problem and wanted to check some other things in our system, thinking perhaps there was another problem causing the thermostat to shut off. After some more investigation, Nicholas found that the fan speed was set too low during the new installation last year, which was causing excessive heat and tripping the system to shut off. This solved our problem, and he saved us over $400. We would like to commend his diligence and motivation, since he was thinking about this during his off hours. It demonstrates that he is a very capable technician who should be encouraged towards more responsibility and higher level work. Thank you!”

“I have been a customer of Environmental Systems since 1976. I would like to recognize Maureen(office contact) and Scott (our tech) for an outstanding job recently done for us – last week before the snow began we had no heat-Scott had someone troubleshoot our Carrier model and came to our home twice to make sure the proper repair was done before the storm. As a seasoned (older) realtor I have provided Environmental's name to many clients thru the years they provide outstanding service in a very professional manner.”
