HVAC reviews in Greeley, Colorado

Thomas serviced both of our fireplaces and did a great job! We will definitely have him back again and will likely add HVAC service as well. Highly recommend!

Installed a new HVAC system including a new hot water heater.

Thomas and Will did a Superior job installing the
furnace, heat pump and hot water heater.
They worked ALL day to make sure everything was working properly before they left.

Aaron and Mark installed the humidifier.
They did a great job as well.

Very kind and professional staff. They are always able to answer any questions and provide me with any details or explanation needed as they were installing my new ac. Staff is always willing to work with what time and date works best for you when scheduling services and installs. It is always a positive and learning experience.

Aaron was very professional and knowledgeable. He listened to me and my thoughts and ideas and was kind, courteous, and was awesome to deal with. He spent the time to make sure it was a broken part and not just something stuck in the system causing the alarm and broken system.

Highly recommend!

We had a great experience with a recent warranty repair on our furnace! Barely an hour response to the after hours call on a Sunday and installation the next day. And a great value to boot!
Will definitely use A-1 in the future

Update 2/15/2022: I will continue to rave about this company! Super fast and friendly service! They ALWAYS find the problem and have been so kind and understanding every time! The Owners are wonderful and they do a fantastic job finding wonderful employees to represent their company! I still continue to ONLY use A-1 and recommend them any chance I can get.

A-1 has always been Fantastic to do business with. We got our central A/C system installed by them and they even came out to inspect it when things weren't working right. Turns out the issue was user error but they did such an amazing job of being patient with us to explain the issue, educating us on how to better care for our system, and even made sure the entire unit was updated and running smoothly before they left. They are fast in their responses and their 24 hour service is great highly recommend A-1. We won't use anyone else!

A+ Infinity! I called 3 companies, the guys were the first in everything, insurance, communication, service, diagnosis and turn around time!

I recommend this company and have used their service several times. I had a great experience, the person who came out was Thomas. Thomas is professional, friendly, well mannered and explains things easily. I like that he called before arriving and told me he was on his way. My A/C need a repair & check-up. Everything was explained to me & service was completed.

I always use A-1 Heating and Air Conditioning for all of my HVAC needs. They are family owned and operated, and they are honest, friendly, prompt and thorough! I was told by another HVAC company, that something was cracked and was going to cost me thousands to fix. A-1 came and discovered that what I needed was a $30 part, and that the other company was ripping people off blind. The techs are so knowledgeable I will never use anyone else. I strongly recommend A-1 Heating and Air!

I was having trouble with my furnace and a friend recommended A-1 Heating and Air conditioning Services. I had to replace my furnace and the technicians were very helpful. The price was very reasonable! I recommend them to family and friends.

I have used this business twice now to repair and tune my furnace. Both experiences have been exceptional. Both of the guys who came at the two different appointments were extremely courteous, very professional, knowledgeable, and timely. For both appointments I have had they were able to come to my home based on what worked best with my schedule and were very flexible. They arrived when they said they were going to and fixed everything that needed to be fixed without taking an entire afternoon. They explained things in a way that made me feel like I understood what was being worked on without feeling like I was being talked down to. I will continue using this company for all of my air conditioning and furnace tuneup and needs in the future!

I Love A-1! They have been my go to company for nearly 10 years. I love that they are locally owned, and they truly care about their employees! I almost always have Aaron or Thomas out at my house, and they are so respectful! There have even been times I had to let them in when I wasn't home, and I have 1000% trusted them to be in my house with out me there. There is no other company I would trust to work on my furnace, AC or Fireplace! Thanks for all you guys do!

5 stars for Cody and Spencer! Nothing went smoothly but they worked through every challenge and put together a great system. Support from Brad and Braun answered all questions and solved any technical system problems. All work was performed in an efficient and tidy manner. I commend all involved for their helpful, courteous approach to their jobs. we highly recommend A-1 for their professional work product.

Aaron is awesome. He is very knowledgeable, courteous, friendly. Only down fall is company should do their own finances instead of doing loans

I have used A-1 Heating and Air Services a couple of times now and have been very pleased with their work. The techs are friendly, knowledgeable and do a good job! I have referred A-1 H & AS to friends and clients as well. Keep up the good work!

Will &. Cole were really great. They did a fantastic job installing our new furnace and humidifier. They were very professional and respected our privacy and were great with our dogs, who occasionally need to supervise their work!

We have used A-1 Heating before, and they have never disappointed. And Aaron was very helpful, answering every question we hit him with. We also appreciate the fact that they fixed our 35 year old furnace a few years ago to try to keep her going, and it did. This time, we had a blow back that rendered the old girl inoperable, so we decided 35 years was an admirable service record, and bought a new one. The warranty on our new furnace is longer than I will probably occupy the planet, so we are delighted.

Thank you Aaron, Will & Cole, and A-1 Heating & Cooling!!

Aaron was absolutely amazing and professional! He did everything he could to try and save me money while fixing my furnace! I would not ever call anybody else except for A-1 Heating And Air. I am so grateful and appreciative of his service that he gave my home!

All of the employees here are kind and knowledgeable. They are straightforward and won’t surprise you with hidden costs. Thomas is an exceptional technician who is reliable and honest—and he isn’t judgey if you forget to change your filter :) There is no place better to call and no one else I would trust in my home.

We are so happy with the service. The young lady at the front desk was so helpful with our options and scheduling. Aaron did the estimate within a few days and by the next week lead installer William and assistant Mitchell were there to install. William walked me through every step and was so curteous and professional. They made sure we understood everything that was done and answered any questions I had. I would recommend this company and their staff are great representatives. It's only going to get hotter this summer. Give them a call. Martha

Today we had the pleasure of working with Thomas, from A1 Heating and Air Conditioning. He was a fantastic technician and was very informative and professional. He was able to get to our home the same day we called and quickly diagnosed the issue of our furnace. He was just as professional and informative when he spoke to our landlord to relay the information and asked for confirmation before he moved forward with the repairs. I highly recommend A1 Heating and Air Conditioning to anyone needing repairs done quickly and to those who have landlords/are landlords.

Our AC went out yesterday afternoon. I called A-1 this morning and had the friendliest tech out by 1230. He fixed it without issue and for a much better price than any other HVAC company I have ever used. Highly recommend this place!
