Get matched with top air conditioning pros in 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!"

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

"Installed new a/c, furnace, air filter, humidifier, and water heater. Very professional and helpful group."

"I called, not knowing what was wrong with my air conditioning. They actually gave me a few possibilities, over the phone, one of which turned out to be the Culprit. No charge for the advice, they could have easily rip me off. But didn't. They won't give u the run around, and tell you somethings wrong when it's actually not."

"Mike was awesome, very knowledgeable and friendly. Efficiently got the furnace running as it should be! Even took the time to educate me on what the issue was and explained what he did to fix it. Highly recommend!"

"I called Bernie this morning after my home warranty company had not assigned a tech to repair my central AC. He was not only professional but more importantly an overall great human being with the understanding we have been having excessive heat Bernie still made time to come out. Not only did he get to my house quickly he was able to replace the part needed to get me up and running. He then went above and beyond to ensure it was working correctly, changed my filter, and made sure the air was blowing at the correct temperature. He was extremely reasonable and more importantly without hassle filled out the paperwork needed so I would be reimbursed by my warranty company. If I could give him 10 stars I would and I would highly recommend using him for repairs."

"Install a heat strip to AC handler in attic. He provides service with a smile."
