Testimonials

When I called to get a quote, the lady who answered the phone was very respectful and answered all of my questions. A young gentleman came out and gave me a quote for a new furnace and A/C. He was very knowledgeable and very honest. The quote I received was not the cheapest, but very reasonable. I went with A-1 for my install and they did a beautiful job and my system works great. I would recommend A-1 for any of your cooling and heating needs.

Slade has been our furnace repair man for the past several years. My husband and I could not be more pleased. He ALWAYS comes immediately when we call –even giving us his cell number in case we had a problem after a particularly large repair. He knows us and our family and is always very professional and efficient. He always spends time trying to explain the repairs that are needed and we have never had to wait for repairs to be performed. On this particular occasion, he upgraded the unit he repaired but actually found us a discounted part saving us a few hundred dollars. Slade has never disappointed us!

Testimonials

Wonderful customer service! Communication is always timely and professional. We’ve had our AC and our furnace checked out annually by A-1 for many years. Usually, A-1 contacts us before we need to call them, to schedule the annual maintenance checks. This is much appreciated in our busy world! Being proactive is always a huge plus! Better the problems that never occur due to careful maintenance than the ones needed due to sluggish maintenance. Thank you A-1 for your top notch customer service and professionalism.

I have a rental AC that stopped working and another with a pretty old furnace I needed inspected to make sure it worked, was clean and was safe at its age.

The tech name was Aaron. He communicated well and called me 30 minutes before he arrived. Worked well with my renters and kept them informed of any findings. Called me when the work was done to let me know causes, issues and reports of the work. Work was done in a timely manner. Cost wise falls in the middle not the cheapest not the most expensive either. Will go to again in the future for any HVAC needs. Favorite part is excellent communication which is great when I can not be on site to meet someone.

Fantastic job installing our new furnace and A/C units. They were quick to come out when we found out the furnace gave up and quickly diagnosed the problem. Recognizing the age of the furnace, they gave us options and things to consider. They did not pressure us one way or another, but allowed us to make our own decision. After reviewing our options we decided a new system would probably pay for itself and decided to go new. The showed up the next day, professional, courteous and set up our home putting down protection for our hard wood floors, tile floors and carpeting. The crew worked quickly and efficiently. Between the guys that showed up and the owner working with them, they were able to complete replacing both the furnace and A/C unit, show us how to operate everything and told us to call if we had any questions or concerns. Considering the cost of replacing both, we were so happy with the result and a warm home. Looking forward to seeing how the A/C does this summer too. If you need any service work done on your heating or Air Conditioning unit, I would highly recommend A1 Heating & Air in Greeley!!

A1 did an excellent job on our furnace and ac replacement after our old unit failed. The new unit also seems to be keeping the temp better regulated and the filter already looks filthy indicating it is doing its job unlike the last setup. I really appreciate everyone that works here and what they do!
