Cordts Heating & Air Conditioning, Inc. is a family owned and operated business that has been serving the Pekin, Illinois, area since 1975 with exceptional customer service. Our experts provide residential and commercial customers with professional installation and maintenance of high efficiency furnaces, air conditioners, geothermal heat pumps, air purifiers, air filters, and humidifiers. Plus, we're equipped for custom sheet metal fabrication and installation.

"I cannot sing the praises of Cordts Heating and Air loud enough. Our old furnace crashed right before a cold wave hit. Not only did Cordts give us the most fairly priced estimate for the work, but they made the installation "urgent" and had the system installed in our home less than 2 days after Brad came to give the estimate. The crew was professional, courteous, and did a FANTASTIC job installing the new system. The house was toasty warm within a couple hours after they finished the installation and testing of the system. We are very pleased with the entire experience and will be recommending Cordts to anyone who's having an issue with their heating/cooling system."

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