“We called yesterday with an air conditioning issue and Tyrone was here less than 24 hrs later! He took the time to explain everything to us and was so easy to talk to. He was very respectful to our property. He is a wonderful representative for this company and we would call on him again for any heating and air conditioning problems. Thank you.”

“One Hour Htg.& Air is awesome. My Tech, Terrell was very knowledgeable and detail oriented. He discovered an issue that wasn't fully covered by my service contract, yet was no fault of them or I. One Hour worked with me and we split the bill! I am a satisfied customer and highly recommend One Hour for your HVAC needs!”
