Best Carbon Monoxide Test in Denver CO

Very knowledgeable technician! I had one job in mind and the tech walked me through multiple options that would have cost less but got the same job done and then let me decide which route I wanted to go. offered to follow up with some extra small services related to the job that I wasn't even thinking of and then walked me through how to do my own maintenance on the new installed parts.Very respectful and polite tech too.

Horizon is always prompt, professional and does a great job.

Ryan ( Technician ) was cordial and explained everything throughly. Work was done in a timely matter.

This place is not worth your time or money. I called them out to replace a kitchen faucet. They refused to give me any idea of what they charge over the phone, so I ended up paying $70 to have a guy come out and bid the job at $500!
I ended up using Skul Plumbing, they gave me a price range over the phone, came out did a great job and charged $200.

Huge thanks to Nate and his crew for saving me while we were seeing record setting heat here in Denver! Super impressive! Within hours of them being here, my home was nice and cool. They were very professional and polite, my dog even loved them enough to not bark! Very efficient as well and left no trace of being on my property. I highly recommend them!!
