"Could not recommend this company more to help you with whatever you HVAC needs are. Knew I would need to replace my A/C system at some point and that day finally came. Absolute Comfort was there the next day to give me a quote. I chose to get a full system (AC & Furnace) and their price beat a quote from another company by $1,500.. and the competitor quote was for only the A/C. The installers were professional and personable despite the attic being extremely hot on the day of installation."

"Kamara is THE BEST. He fixed my HVAC problem and at affordable price, where Morris Jenkins couldnâ t fix it. He has very good knowledge about the system. He puts his heart and soul into the problem to fix it and his work definitely speaks. He walk through the system, the problem, the options and cost effective one out of it. I was able to gain some knowledge on the HVAC system and a big thanks to him for that too! I was a Morris Jenkins priority advantage member and now I got rid of it and I chose to go with Kamara for any further HVAC maintenance and itâ s problems. I would definitely recommend him and obviously 10/10."

"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

"I  had never had the service before in any of the other homes I owned.  I was not sure what to expect and how the cleaning process actually worked.  The two gentleman arrived right on time.  They explained everything to me and how the equipment worked.  After walking through the house, they unloaded the equipment and went right to work.  Whenever I asked a question they it was answered.  Before they left one of the gentleman asked if I had a clean filter for the HVAC unit and offered to put the new one in for me.  I did and he did.   The entire process took about 90 minutes including making sure everything was cleaned up before they left. .  I would definitely used the service again. Very professional, efficient and informative.

Heating and Air Conditioning questions, answered by experts

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
