"Everything went great. They showed up in the morning and had everything ready to go by about 3:00pm. We replaced an 80% efficient furnace and 10 SEER A/C with the Carrier Infinity 98% efficient and 16 SEER A/C. Because the furnace is a high efficiency condensing gas model it requires PVC intake and exhaust piping. We agreed on a suitable location out the side of the house for the new piping. The install went well. They even fixed an existing return duct in the basement that was blocked off. The basement heats/cools so much better now. In fact, we have 2-story home and the whole house is more comfortable. There's not as much stratification of the temperatures from level to level. As far as the equipment it seems to be running great. Both the furnace and A/C are 2-stage units. This means they operate at two different output levels. The thermostat is the Carrier Infinity Control with WiFi. We had a Nest with our old system, but it is not compatible with the Carrier Infinity line because of the complex controls needed to operate the system. That's okay. This new thermostat is much better anyway. It requires a proprietary communication data bus because it is constantly monitoring the state of the various components (furnace, A/C compressor, ECM fan motor, evaporator coil, etc.) and adjusting the control parameters continuously for optimal performance and efficiency. It will even put the A/C in dehumidify mode where it lowers the air flow across the evaporator coil to more effectively pull water out of the air. We are pleased enough with the system that we'd never use anything other than a high efficiency 2-stage (or even fully modulating) system when/if we ever need to replace things again in the future. This is our second positive experience with these guys. We will continue to use them for any future needs."

"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 was upfront and honest through the whole project. He's the kind of guy you can trust with a handshake. John gave me several options including repair or replacement and we discussed the plusses and minuses of each option. We agreed replacement of my 20 plus year old AC with a new 16 SEER unit was my best option. My old unit ran non stop from May through September. The new unit cycles on and off, even on the hottest days, as it has no problem keeping up with the cooling load in my house. I'm still waiting to get my first electric bill after the new install, but I'm sure it will be considerably lower. The whole crew was very friendly and professional resulting in a great finished project and a much cooler house."

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