"1st Action Plumbing and Heating replaced our furnace and hot water heater. Iâ m happy with the work they did. The crew that did the work were great. They explained everything in understandable detail. They stay in contact about when they will arrive and are on time."

"Ruben was awesome. Installed an A/C unit and a new furnace in 1 day. Super nice and relatable. Did great work, even dealt with my dogs barking at him everytime he came inside, haha. Cannot recommend enough. Gave us a great deal and great service. Kept in contact and kept us informed. 10/10"

"One Hour has been my HVAC supplier for more than a decade, and I have never had a reason to consider any other firm. This week Justin L. and Steve came to install improvements. They were professional, courteous, and took the time to explain to me just what they were doing, and to answer my questions. On a scale of one to ten they were both elevens. I'd give them six stars if I could. You can trust One Hour to do it right."
