"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."

"My overall experience with Porterhouse Heating & Cooling was very good. I called and requested same-day service due to a gas leak. Porterhouse Heating & Cooling came out that day, replaced the shut-off ball valve, and tested the system after the repair was complete. Also Porterhouse Heating & Cooling ensured the tankless water heater was operable since gas to the house had been shut-off due to the gas leak. Additionally, I had them to conduct my annual preventative maintenance on both furnaces. This was my third (3rd) time using Porterhouse Heating & Cooling. I find them to be responsive, knowledgeable, and customer-focused."

From the first contact person I talked with to the person who performed the cleaning at the house, everyone provided excellent customer service and did a wonderful job cleaning the ducts. I will certainly use this service again. Thank you for all you did for us. "

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"Very pleased!! Plus, he assured me that our Furnace did not need to be replaced at the time, as he checked it very thoroughly and said it had been serviced well by prior Furnace company. He was done in a little less than 6 hours, and cleaned up the area needed very nicely."

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