"I had Kevin of S&K repair my A/C condenser. He did a thorough check of my system, did the repair, and everything is working fine. It turned out to be a minor repair, and they did not pressure me, or upsell me any services I did not want (really appreciated that!) I would definitely recommend this company to others."

"Tyler was a total professional. He explained what needed to be done and the time and cost involved. Iâ m a senior citizen and Tyler could see I was struggling without the a/c in the heat wave we were having and he actually lent me the use of his own a/c until mine was repaired. Thank you so much Tyler!"

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"From my 1st phone call to ask about the services they provide and costs to when RJ & Walker left I've been completely satisfied. My appointment time was from 1-3 and they showed up right at 1pm. RJ & Walker both walked up to me and introduced themselves with a firm handshake.  We toured the house looking at all the vents and air returns along with the furnace. Then RJ fully explained what he would be doing and the Walker explained what he would be doing. They answered all of my questions.  About 30 minutes before completing the job, RJ asked me to come downstairs and he showed me all the dirt and stuff that came out of the vents. He showed me how he closed up the intake points he had to make in the duct work. They removed the equipment and everything was put back as it was and left clean. The entire time RJ & Walker stayed productive, friendly and professional. It was a pleasure having them in my home to complete this service."

FAQs for central a/c service or repair projects in Union, KY

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.
