Get matched with top heating and air conditioning pros in Clayton, MO

"The technicians are so nice and helpful, professional, and punctual. They've maintained my hvac for the three years I've lived in this house and all runs smoothly."

"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

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

"Great. Brandon knew his stuff. He conducted and airflow test to show us where our leaks were. He provided suggestions on where we could best reduce leaks. He also looked over our structure (joists) and HVAC system, again, suggesting improvements. Well worth the investment!"

"Extremely fast replacement heating and cooling installation. Exceptionally nice people. Zero problems after the installation of 2 Furnaces and 2 Air Conditioners in our zoned HVAC home."

"Liberty did a fantastic job identifying and rectifying airflow problems with our existing Hvac system that was installed less than two years ago by another company. They were punctual, responsive and incredibly knowledgeable. I highly recommend them."

"They were professional from the phone call to the installation. He had everything he needed to replace the hot water heater and proceeded. I would definitely recommend Hosack Plumbing."

"I finally found an HVAC technician that really understands HVAC. DT Restoration will be my service company from now on. Thank you Home Advisor."

"Seems I was spending a ridiculous amount of money on electricity because my central unit was not operating correctly. I now have flowing cold air."

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."
