"R&J Preventative Maintenance responded immediately (on a Sunday!) and they had someone out the next morning to diagnose and repair the issue with our 2005 beverage fridge! We did not want to replace it and he had the parts with him and was able to repair! Amazing! (He also serviced our Sub-zero fridge!) We will definitely use them in the future and highly recommend!"

"Dave from Champion Technologies was at our home within 2 hours (8.00 Dave came to see us Sunday evening, after hearing we had no heat and Temperatures were 5 degrees outside . He was very professional, kind and listened to our needs. He had a crew, Greg & Peter, at our home the next morning with a new furnace who installed it and had it up and running by 1:00PM. I want to thank them so much for great service. I would highly recommend Champion Technology Services, LLC ."

"They were professional, efficient and made sure we were up and running within a day of diagnosing a big problem. Our blower for our A/C went out and was unable to be repaired within the month due to parts not coming in time so we made a decision to get a new one since ours was 10 years old and they got us set up with a warranty and installed the next day!"

FAQs for central a/c service or repair projects in Gary, IN

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.
