He answered all of our questions in great detail and was super personable and professional. This was even though we were his last stop of the day and he did not get here until almost 6 pm. A huge asset to FCHA and why we continue to use them.Posted on Google Andrea JenkinsTrustindex verifies that the original source of the review is Google.

Zack was wonderful! He was helpful, honest, and respectful. He did not try to over sell services, and he absolutely over delivered. We will certainly call again for future work.Posted on Google Randy WeissTrustindex verifies that the original source of the review is Google. Orel was thorough in his work, explained in simple terms what he was doing and looking for. He was honest in his assessment of the A/C; didn’t try to sell me something I didn’t need. He extended his appointment to do the blower assembly cleaning. He could have scheduled it for a later date but instead took the time to do it then and not have me wait for another appointment. Much appreciated it.Posted on Google Thomas de SostoaTrustindex verifies that the original source of the review is Google. The Fort Collins Heating and Air Conditioning installation team was exceptional. From assessing our needs to putting the final touches on our new heat pump and furnace system, the crew was professional and meticulous. What impressed me most was their commitment to customer education; they took the time to explain all of our options clearly, ensuring we felt confident in our decisions. I highly recommend them for their expertise, seamless teamwork, and attention to detail.Posted on Google Seth SonnierTrustindex verifies that the original source of the review is Google.

Today we had Brent out for our furnace maintenance.This was our third time to have him (we request him now), and I cannot speak highly enough about how thorough and professional he is.Posted on Google Raquel ShustaTrustindex verifies that the original source of the review is Google. We've used Fort Collins Heating and Air for both our heating and AC, and honestly, we can't say enough good things. From the first call, they were responsive and actually showed up when they said they would — which, let's be honest, isn't always a given these days. Both Micah and Brandon have been out to our place, and it's clear these guys know their stuff. They didn't just fix the problem and leave — they took the time to walk us through what was going on, what they were doing, and why. No upselling, no mystery charges, just straight talk and fair prices. It's refreshing to work with a company that treats you like a person instead of just another job on the schedule. Friendly, professional, and genuinely good at what they do. If you're in Fort Collins and need heating or AC work, don't waste your time calling around — just call these guys.Posted on Google Brian DetersTrustindex verifies that the original source of the review is Google.
