About
WE ARE CURRENTLY OFFERING A $49 INTRODUCTORY MAINTENANCE! Anyone can get to your house fast. Fewer can get it right the first time. At One Hour Heating and Air Conditioning of Seattle, we diagnose before we quote and we don't leave until the system is running the way the manufacturer intended. We carry a Washington 06A Electrical Administrator license, an 06A journeyman on the team, NATE certification, and a Seattle Refrigeration Contractor's License. That's more credentialing than most residential HVAC outfits bring to a service call, and it means the electrical side of your install gets done to code by people who are licensed to do it. You get the price before we start. You get straight answers on repair versus replace. And you get a clean job site when we go. Heating, cooling, heat pumps, and mini-splits across King, Snohomish, and Pierce Counties. Nights and weekends available. Message us and let's get it done properly.

Update: After posting my original review, the owner Alex reached out personally and issued a refund that accounted for the high pricing and inconvenience of the experience, without being pressed for that amount. He also shared that he is actively working with the national franchise pricing model to bring rates in line with the local Seattle market. I appreciate the owner's customer service and professionalism.Original experience: The technician was professional and correctly diagnosed a failed contactor in my outdoor unit that was triggering a Nest thermostat error. The repair took two days due to a parts miscommunication, and the job was billed as a single flat-rate line item of $493 with no parts/labor breakdown, significantly above what an independent HVAC company would typically charge for the same repair.Bottom line: the initial experience had real rough edges, but Alex handled the follow-up with honesty and professionalism. Given the experience as a whole, I'd work with One Hour again.

Hello Nick, Thank you very much for your feedback. I would like to first apologize that the pricing was not explained to you before the work was performed. This was a training error on our part, and I take full accountability. Mark is an experienced technician but new to our system. As such, if you could contact me, I would love to issue you a refund for our mistake. As for pricing, we do use up front Straightforward Pricing so as not to give you sticker shock and so that you can refuse work based on the price. I am sorry we did not give you that opportunity during this engagement. We will make sure that does not happen again. Our price for the repair does include the dispatch/diagnostic cost as well as our industry leading 2 year warranty on parts and labor for the repair. Thank you and I hope you will give me a chance to correct our mistake! Best regards, Alex

We had an outstanding experience with this team from start to finish. From the initial scoping and planning through the full installation of our HVAC system, they were knowledgeable, efficient, and extremely professional.The installation was completed impressively quickly without compromising the quality of the work. What stood out most was their flexibility and responsiveness and they were always willing to accommodate every modification we requested and approached each change with a positive, solutions-oriented attitude.They made what could have been a complicated project feel smooth and straightforward. We are extremely happy with the final result and would highly recommend them to anyone looking for a reliable, skilled, and genuinely customer-focused HVAC team.
