  Highly recommend One Hour Heating and Air Conditioning. Nick is exceptional - very knowledgeable and customer oriented. He gave me multiple options to choose from and let me pick the best one for my needs with no pressure. I’d do business with them again.

  Was visiting friends in Tukwila got to see One Hour Heating Come out to fix an HVAC issue. Devan was so knowledgeable, explained what the problem was and provided various options and was able to fix the issue and provide a 2 yr warranty on the work done. Would highly recommend One Hour for any HVAC or air conditioning needs.

  I had a great experience with One Hour Heating & Air Conditioning. The team was professional, honest, and extremely knowledgeable. They arrived on time, explained everything clearly, and made sure the job was done right the first time. What I appreciated most was their attention to detail and the way they treated my home with respect. It is clear they truly care about their customers and take pride in their work. If you are looking for reliable heating and cooling service in the Renton and King County area, I highly recommend them. I will definitely be using them again in the future.

  Devon was always prompt with responding to my questions and keeping me informed. Nick the installer was the kindest hardworking young man explaining everything sometimes twice and letting me and hubby know why it took another half day to complete the project.

  Denis is excellent!!! I am happy to refer him to my Mercer Island and Renton neighbors. He is great business man and takes wonderful care of customers. He is an Army active reserve as well which I can see the organization and skills he brings to the company. HVAC has never felt more easy!
