"Marcus is great. He's serviced my house several times for both AC and furnace maintenance. He's very knowledgeable and thorough. Takes time to explain things and answer questions. Also offers suggestions, but doesn't pressure you. He's very efficient. Appears to be an honest HVAC tech and good guy."

"For several days my Furnace would not come on. I went on home advisors and and put in my request for Furnace Repair and got several options I read the reviews for each option and I decided to give McKinney Services a call. i placed a call to MCKenny services. Mr. MCKenny called back and I explain the problem to him. I made an appointment. He called when he was on his way. Very professional and courteous. I felt comfortable. He checked my furnace and luckily on my part it was a quick fix Amen.Ii was only charged a service charge. I been looking to replace my usual go to person for some time now i think i will stick to MCKenny services from now. Ms. Howard"

"John contacted me immediately after I submitted my project to Angi and came out later that same day to do an AC tune-up. He was professional, easy to work with, and respectful of the property. He diagnosed a few issues and possible solutions at varying price points, and went into the pros/cons of each one. I plan on having him come back this fall to check our furnaces."

FAQs for central a/c service or repair projects in Maryland Heights, MO

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.
