"I have used Home Comfort on prior occasions to service my old furnace - they had replaced the capacitors and the main blower fan but on the most recent issue, the secondary fan went out. Rather than have it repaired (and seeing the number of repairs increasing each year), I decided it was time to replace the old furnace with a new one. I got a quote from Home Comfort for a new American Standard Gas Furnace with a 95% efficiency - it was scheduled for a Saturday. The serviceman was at my house at the time scheduled and had the entire work completed in about 4-5 hours. He was helped whenever necessary by an additional helper. They took the old furnace out and disposed of it and got rid of the packing material that the new furnace came with. It has been about 2 weeks now since the furnace was replaced and I have had no issues with the new furnace at all - it was done right the first time around. I would have no hesitation recommending this company for repairs and installation of HVAC systems."

"After 4 hot days with no cooling from my A/C system, it was a welcome relief to know within 20 minutes that the issue was likely a malfunctioning part (which Kevin showed me). He kept me well informed during the entire visit and was quite professional in his conversations and handling of the problem. And he remained on site until he was sure everything was working correctly. I would love to have him back for all my repair needs!"

"I am beyond happy with the service! I found Mr. Duct through reviews by my neighbors on NextDoor.com. They said your service was great and you provided flat pricing with no "surprises."  I was overjoyed to find that was true. Taylor took my initial call and provided pricing and scheduling options in minutes along with coupons and discounts. It was so easy!  Tom called me the day of my appointment to let me know the technicians would be arriving shortly which was very appreciated. Omar G. and Corey were the technicians who completed the job and they were incredible! I was scheduled for a dryer vent cleaning and vent hose replacement. It was for a rental clean up that had not been used in years so they went above and beyond to clean out bird nests and bees nests (in the rain as well) and simply said they were happy to do it and it was their job.  I feel it was above and beyond the job and I cannot thank you enough. I feel at peace and safe knowing they did a thorough cleaning. I am grateful to have found your company. I will be scheduling annual cleanings every year with you from now on.  Thank you all so much for all your hard work. It is appreciated"

"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"Cody showed up on time. Very polite young technician Appears to know his job well. He examined the indoor part of the system. Verified what initially indicated to his office that Freon is needed. He indicated that vents need to be cleaned before sealant and Freon can be added. Cost was as follows: $96 diagnostics + $203 for 1.5 pound Freon & labor + $60 another 30 minutes labor + $187 sealant (cost $27 on Amazon) = $545. System is working well. This cost is significantly higher than last service provider."

"Great! Everyone at AnyTemp is extremely responsive and punctual, always calling if they are running even slightly behind. Both Sal and Antonio have worked on our furnace and both are extremely professional and knowledgeable as well as being a joy to work with. Every time I have called for service they have been extremely responsive. In short, there is nothing they could do differently! They are wonderful to work with."

FAQs for central a/c service or repair projects in Glen Ellyn, IL

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
