Same-Day Boiler Repair
The boiler in my small office building stopped working and I called Quality First to handle it. Every other vendor I called didn’t have any availability for nearly a week, but Quality First was able to make the repair the same day. Sam was an amazing technician who quickly figured out the issue and got the boiler up and running within a few hours. And the cost was very reasonable. Definitely recommend Quality First and will absolutely use them for future plumbing needs!

Dan Perkins
Very responsive and flexible
Very responsive and flexible with scheduling when I needed a boiler fix in a hurry in order to restore hot water and heat supply. Unlike another company I had come out originally, NOW got the job done rather than leaving me without a resolution. Jeremy listened and resolved the issue without an attitude and with upfront disclosure of the cost.

Big shout-out to Ian Thoele
Big shout-out to Ian Thoele, our account manager on a new high-efficiency boiler and hot water combi system retrofit for our home in Louisville, CO. Ian went through multiple options for us to come up with a solution that was a good compromise between cost and high-tech features, and was able to get everything installed on a schedule that allowed us to go on vacation and not have to worry about coming back to a cold house. Good communication and good follow-up. I highly recommend NOW H & C for anyone needing HVAC care.

Very thorough and well-founded recommendations
Pete, the Quality 1st technician, performed a yearly pre-winter diagnostic inspection of the boiler and heating system. He was very thorough, answered every question I asked, and provided a detailed explanation of what he found and provided well-founded recommendations. For these reasons I am happy to recommend Quality 1st… and Pete. Also, I was kept well-informed of his arrival time.
