One Hour Heating & Air Conditioning of St. Louis

Erik did a great job of explaining what needed to be done and completed the work efficiently.

Nathan was very direct and straight to point. Wasted no time which I liked. Was willing to explain in detail what was going on. Price was more than I wanted but the quality of work makes up for it. They also cleaned up there areas after they were done.

Robert Fitzgerald did a great job, checking and servicing our heating system today. Prompt, thorough, courteous - to be recommended!

Robert was polite, professional, and knowledgeable. It was a pleasure to have him in our home.

This company is the best. Always on time— they’re great at keeping you informed about what they are doing and the status of your ‘item’ (i.e. Air conditioner, furnace). Regarding a previous situation— they have integrity! Honesty!

Josh came and tied up the loose ends from the install promptly and professionally. Good job Josh!

Eric was very knowledgeable and answered all my questions while being polite. Great service hands down.

Excellent Company from the office to all three technicians. Super sweet and professional and the best part FAST!:). New AC is running great Thank-You!

Always polite and helpful. Yearly service program is great, low cost and helps make sure you system is running smoothly

Professional and prompt. Called to let me know when he would arrive. Quickly assessed system and determined best solutions Staying in the discussed price range.

Very quick and accommodating with my system issues. Went above and beyond to develop a solution and make the repair to the AC Compressor unit. Great service overall.

I had a really good experience with them. They got me in and fixed my A/C within 24 hours. Ferrell was very nice and I appreciated that he wore shoe covers when he came in the house. I didn’t request that, he just did it. I will use them again and would recommend.

Rob was awesome! He showed up on time and efficiently fixed the issue. Appreciate the help and the professional manner in which it was handled. Thank you!

I greatly appreciate the quick response and the efficiency the technician used to help me get my AC unit up & running. It feels great in my home now & if you ever have a tech come thru, tellem to drop off a sign. I would be more than glad to represent JT Dunn Heating and Cooling. Sincerely Mike Cook.

Our technician Farrell did an excellent job. He was prompt, knowledgeable and very professional.

Over 500 dollars to move one wire said it was fixed. Worked for 40 minutes and they wanted to charge more to come back an 7 times the amount for the part they said would fix it again. So over 500 for a 30 minute rig job that they said was go to go when they left. Don't use this company

Nathan did a great job, everything is clean and functioning well! Will definitely use 1hour ac again.

Erik has assisted us twice for air condioning issues. He has been polite, professional, and very helpful on both occasions. We are happy to recommend One Hour Heating & Air Conditioning.
