"I had some backup into the basement, they came to rod it out and told me I needed to check the line going to the street and they could come back for a video check. Well they said they came back and took the video and I needed some expensive work to clear the line. I called to ask them for the video, they said that they'd have someone call me back. They called me back and said that there was no video, their worker didn't put in a USB drive and besides they said I didn't ask for one. What did they expect I was asking for??? I said I expected and wanted a video, how do I know they even really performed the work. They said they would call me back. THEY DIDN'T. I called them back, they again said they'd call me. Again no call. The last time they told me, the owner was on another call but would definitely call me back. One week later NO CALLBACK. I firmly believe they didn't do a video, charged me for one and took me for a sucker. I will NEVER use this company again. I think they are crooks. P.S. Ever since they rodded the drain one of my toilets started have trouble flushing. I won't doubt they messed it up so they could come back again for more money. DO NOT USE. P.P.S. I wonder if they will contact me on this posting, I doubt it."

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