"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"Project: Repair or Service a Central Air Conditioning System Sam from Liberty is GREAT! I had my AC recharged earlier this year and they charged me $170 per pound for freon!! This is the dirty little secret..You (and they) can buy it for $29 a pound on the internet....so I lost the first round with SmartHouse??? overpaid for 2 pounds plus service call plus labor.....A month later. I accidetnally cut a hole in my line in the garage.lost 5 pounbds of freon.I called all the AC companies I could find and asked them how much per pound the cheapest was $85!! some for $150!! Oh they all lie to you "the price is going up" R22 freon will be outlawed in 2020 our costs have gone up" BS! they all want to stick you for maybe an extra $600 wihtout you knowing it if you need 5 pounds. They are all con artists and liars . I checked with about 5 companies and got the cheapeast bid of $1000 ish and most around $1300! I told them I knew about the mark up on freon and they all did their little tap dance. I finally found Sam on Craigslit under services rendered...Called him he said he would give me a fixed price he knew all about the markup scam! He got the job done for $525!! Sam is a hard worker and didint show up til 7pm and had one more call that night after me! He welded my pipe vac'd the system and charged it up as good as new! While most of these AC company rackets try to get rich off of each job. Sam has a different philosophy he gives a fair deall and justs works harder than everyone else and makes it up on volume. Also he is a one man company so he has very littel overhead...One slight complaint..he hinted that he would be over by 4:15 PM but didn't make it til 7pm as he has other jobs he said were"ahead of me" I suspecet he got a job that he would lose if he didnt take it right away and could tell I would wait....Just a guess....Anyway it was worth the wait ...they say you can get Good Fast OR Cheap Pick 2. Oh and here is a warning ..If you ask for after hours service from any of the established crooked companies get ready to pay $249 a pound for freon!!!! Less"

"Our A/C failed during a very hot spell in June 2018 in St. Louis. Many service providers we called would not come. We called Vitt and told Jeff, the scheduler, about our problem: we had an old furnace (>50 years old) and had the blower motor rebuilt recently by Commercial Electric. Jeff gave us his cell phone number should we decide to go with Vitt. When I had the blower motor fixed, it was in the trunk of my car. I called Jeff and he sent Vic out that day. Vic and Dave came and removed the blower motor from the car and carried it into the basement. The J box was missing from the motor, and the wires leading to it had been cut too short. Vic spoke to Commercial Electric to confirm the correct approach to fixing the wiring. He drilled a new hole to compensate for the shortened wires and moved the capacitor to protect it from touching the filters in the furnace. He checked the relay box and made sure that the furnace breaker was working. After the A/C was successfully turned on, Vic and Dave checked the condenser for heat and then hosed it off. Both men were polite and listened to my information on the history of the furnace and its problems. They asked me appropriate questions about previous service companies. They were patient about my concerns and knowledgeable regarding older furnaces. The bill was reasonable for service provided by 2 men."

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