Best Central Air Conditioning in Denver CO

Brandon was prompt, professional, and provided high quality service. Our AC went out and he was able to quickly understand, explain, and resolve the issue. We will definitely be working with him again

Our heat went out during the polar vortex! The Horizon guys showed up within the hour, first thing in the morning. Ben and Jon were great, very friendly and professional, they got our system back up and running in no time. Highly recommend!!

Jon was great! Showed up on time and was respectful of the Covid guidelines. We discussed our plumbing issue and he gave us some great advice on how to proceed. We are just getting started resolving our plumbing issue and so far Jon has been the best part!

Knowledgeable, Thorough, Integrity

I had them come out for an A/C tune-up. Adam visited twice. The first time he was concerned about leaking or overfilled freon (really expensive to drain it, initial estimate was quite high to do this!). Second time, he checked it again and determined the coil was dirty. His diagnostics were quite thorough and no other repairs needed. This is an old unit and he helped me nurse it along. I appreciate his willingness to do this rather than try to upsell me. Final fees were reasonable ($300-$400).

Awesome experience!!! I am truly grateful for Brendan and Golden West. I called them because I had received an estimate for over $9k for a new furnace, the previous company said my furnace wasn’t repairable so I needed a new one and also told me my ac had to be replaced as well. Brendan came in and checked everything thoroughly and was able to repair my furnace. Brendan was very professional, knowledgeable and passionate about what he does. So so glad I called them to get a second opinion. 😊😊😊

Excellent service, very responsive to my issue leaking water heater cam after midnight and worked through ymthe night so that I had hot water the following morning. Very reasonably priced true professional that cares more about being n g fir and customer satisfaction than how much money he can get out of you. Could be happier with the service provided

I had the absolute BEST experience with Nathan Fisher. He came to my house quickly and on time to fix a pipe that was actively leaking into my kitchen. He was genuine, kind, efficient, and walked me through what he was doing so that I was aware. He showed compassion and was ethical in every way. He did an excellent job and I feel confident that the work he did was thorough and precise. I will absolutely be hiring Nathan for all of my plumbing needs in the future and am so grateful that he fixed our leak quickly and kindly! He was also the sweetest with our brand new puppy, which I think speaks volumes to his character!
