"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"Went okay. Based on some of my past tuneups, I felt like the tech could have done a little more. For example, tech had no vacuum to clean the bottom of inside the furnace. I am not sure he did any cleaning of the INSIDE of my central air unit either, but he did a great job using the hose to clean the side vents, etc., with the garden hose. Also not sure if he ever used that device with the hoses and gauge usually used to check pressure or is it Freon? For $89.95 for each (central air and furnace), I expect a super thorough job. I can’t get around these tuneups or I will void my warranty. I want to feel uber confident I am getting my moneys worth. Tech was super nice and very professional!"

"We had five companies come out and look at our house and give us quotes for installing a Spacepak or Unico system in our house. Phoenix gave us the lowest quote (16k less than the highest quote!) and also had the best customer service. Everything was explained to us before, during, and after the installation. The owners seem to have a genuine passion for HVAC, which I wouldn't necessarily expect! Anthony was great with figuring out ways to get air to all the rooms in our 110 year old house with many quirks. Glad to have found this company."

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