“Outstanding Service from One Hour Heating and Air Conditioning! I recently called One Hour Heating and Air Conditioning when my air conditioner stopped working properly, and I’m so impressed with their service! They arrived within the hour, true to their name. The technician was professional, friendly, and highly skilled. He quickly identified the problem—a clogged drain line—and cleared it efficiently. He also shared helpful maintenance tips to prevent future issues, which I found very useful. The pricing was transparent with no hidden fees, which I appreciated. After the repair, my system was back to normal, and I noticed improved performance right away. What stood out most was their commitment to customer satisfaction—they ensured everything was working perfectly before leaving. I highly recommend One Hour Heating and Air Conditioning to anyone needing HVAC services. Their promptness, expertise, and dedication to quality make them a top choice. Thank you for a great experience!”

“The technician that came (Ramon) was excellent. He was very knowledgeable and fair with his assessment. We are signed up for comfort club and got a free systems check. He took his time and told us everything looked good. Nothing extra was pushed on us to buy, he just showed us some things to consider. Ramon was very kind, knowledgeable, and funny. Easy to talk to and a pleasure to be around. 5 ⭐”

“Jaiden stopped by the Cottage today and did a great job checking the systems, answering questions, and giving advice. He called approximately 30 minutes in advance of his arrival and was very prompt. He had a great customer service demeanor and is certainly a credit to the One Hour company.
