"on time, and knowledgeable the technician did the job well. Also, I had a problem changing the furnace filter. The filter was getting stuck when taking it out or installing. He repaired that too."

"I needed to check more services than I was able to. I highly recommend Keith. He has replaced our boiler and hot water heater. He also services these units every year. He also replaced our plumbing in our remodeled bath and kitchen. He has serviced our AC units which is very old and need to be replaced but he has kept them going for us for quite some time until we are ready to replace. Which when we are ready we will use him to do this. He is a full service mechanical technician that is trustworthy and very fair priced. We met Keith through a recommendation and that was the best recommendation we have ever received. We have been using Keith for close to 10 years and itâ s great to know that if we have a problem with anything he will be there for us."

"Keith gave us a great quote on replacement of our furnace, A/C, humidifier and water heater. Pointed out a few things that were overlooked by us and the other companies quoting. He and Jimmy came and did the install shortly thereafter in exactly the timeframe promised. All things being pretty equal as far as equipment costs go, it was the over all value that Premier Comfort offered, such as the service and labor warranties that really sold us. We're very happy with the Lennox equipment and the way it was installed. Will definitely recommend!"

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