Get matched with top air conditioning pros in Valley Park, MO

"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"A-ok! Dunn OneHour HVAC is always top notch!"

"I wouldn't have used them to do the air-conditioner if they hadn't done a good job."

"MCS techs were very courteous. New HVAC system install went well. They explained all their work professionally. Also found a crack in the flue and replaced which was overlooked by a previous contractor. They are very thorough and reasonable. I highly recommend MCS."

"Sam was great. Had a extremely dirty system that would not function correctly or blow cold air. Had High Ridge Heating and Cooling here as he has done work before for me and parents. He took one look and stated we needed to replace entire a/c furnace unit for $3100. Told us it would cost about the same to clean. No way I could afford that so went on Angie's List to find someone and read Sam's review's. He came out and told me the cost at $425 to clean. Which was fantastic. He spent about 2 1/2 to 3 hours and did a wonderful job. Ended up paying total $625 once he was done and asked me before doing anything additional that would cost more. Also since our unit didn't have valves on system to reuse our refrigerant he had to put new in which was part of price increase. Sam, thanks so mich for not trying to take advantage."

"Very professional and knowledgeable. Repaired unit and educated me on tips to help maintain it as well. Pointed out issues with the unit installation which was installed in 2006. From condensation line hooked up wrong to finding a filter in the base of the unit, which belonged to the electronic filter system (unit is shipped with filters inside base). Then the air intake line for the heat pump unit never hooked up or ran to outside, and more. I can't say enough."

"They were able to repair rather than replace, which was my preferred solution. I was very satisfied with their handling my problem. The job was done quickly and the service representative was courteous, professional, and left the job site in as good of condition as when he arrived."

"They were on time, efficient. Quality was excellent with a couple of hiccups, which they resolved the same when it failed inspection on hwh. I fixed furnace air leak myself with metal tape."

"The repairman came out on time and found the issue immediately. While he was capable of repairing my compressor, he recommended that I contact the manufacturer to take advantage of a warranty repair. His honesty and details for how to quickly engage the warranty service caught me by surprise, and I will not hesitate to call this company anytime I have an issue. I recommend this company."
