"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!"

"The best heating/ cooling company I've used. My furnace problem was quickly & accurately diagnosed & repaired. The repairman even took the time to show me the 2 possible problems with my furnace. A little pricier than other companies but well worth it."

"The technician arrived within a half hour of our initial call. Although he did not have the part on hand he made a quick trip to their service center and returned immediately with what he needed. The technician was prompt, professional, and knowledgeable. I feel it's also worth mentioning that the technician is also a combat veteran who served multiple tours overseas and is in the process of becoming a licensed plumber. I think it says a lot about a company who hires veterans. I'll never call anyone but Regional Plumbing and Heating for the types of services they provide."

"We were experiencing problems with our central air conditioning unit. It was running, however, it did not cool the condo fast enough. The Four Seasons Technicians arrived on time, very professional, thorough explanation of what was wrong with the unit, and provided solutions on how to fix the unit. He was very helpful in helping me negotiate for a new coil and A/C unit. He was dressed in protective covering during COIVD-19. I would use Four Seasons Heating & Air Conditioning again. I was very happy with their service."

FAQs for central a/c service or repair projects in Evanston, 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.
