Get matched with top air conditioning pros in Lake Saint Louis, 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!"

"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."

"Excellent - Darrin was very prompt, courteous, and happy to answer my many questions. He showed and explained to me how to disassemble the the sink stopper hardware, so the sink stoppers could be removed. Also, he disconnected the drain elbow in each sink, and then removed the many years of built-up hair/whiskers/goo that had slowed the drains but couldn't be pushed out or dissolved with chemical drain cleaners without opening up the plumbing under the sinks. He was completely done with all three sinks in under an hour. The two outside freeze-proof faucets needed to be replaced because of their age and poor conditions. But because Darrin didn't have sufficient time reserved on this date to complete that work, he wrote an estimate up for the work and let me use my $50 credit (I had purchased a discounted Plumbing Service deal from Angie's List for $39.00) towards that visit, but he applied the discounted plumbing service call to this visit (as well as credited me the entire service call for the follow-up appointment, too)."

"Logan was polite, & respectful completed the job in a timely manner. Cleaned up any mess that was made. I will definitely request Logan again for any additional appliance repair I may need."

"The 3 Mustache Pledge! Schraer Heating and Cooling deserves every bit of praise I can give! I called them about a worrisome noise coming from my system — one that I could only describe through a few rather vague and comical sound effects. Despite my less-than-technical explanation, their technician quickly understood exactly what I meant, found the issue, and had it fixed in no time. Their professionalism, responsiveness, and ability to solve the problem so efficiently (and with good humor!) made the whole experience stress-free. I’m so grateful for their excellent service and expertise. Highly recommend Schraer Heating and Cooling to anyone looking for honest, skilled, and friendly professionals!
