I got seasonal maintenance on my air-conditioning system. Scott did a great job of checking all of the filters and cleaning the outside condenser with a hose. He was very polite, very neat and very efficient and informative!

This is the best company out there!! I called a few other companies who came to my home - over quoted me and I felt defeated! I reached out to One Hour Heating and Air— they came within 1 hour! And the problem was fixed in less than 45 min! No large bill! No taking advantage of me! And the best is— my heat blows stronger than ever! I bought my home in 2023 and had no idea it was not working properly until I started receiving $300+ monthly gas bills!! That stops today!! Thank you for saving me money on my Monthly bill moving forward. I needed this blessing ❤️ Service Man was professional as well. Highly recommend.
