Report
Really disappointed that after having an urgent service appointment scheduled they called 1hr before service time to cancel. Was told it was too cold to troubleshoot AC, when in fact my problem was with neither the heat or AC coming on. With freezing temps coming and a tenant without heat, I had asked to still have a technician come out to at least take a look. Was flat out told "No" they would not send anyone.
Another wonderful company in town told me they would be happy to take a look, even though there would be limitations to what they could troubleshoot with the AC. Due to their help, my tenant now has heat on this chilly day! Really unimpressed Greeley Heating and Air was unwilling to even send a tech out for a scheduled appointment.

We have used Greeley Furnace twice this year. The first was this summer when our A/C quit working. The technician who came out was prompt, knowledgeable and professional. We told us we just needed a new compressor, and didn't try to sell us a new unit, cleaned it up and recommended until the unit just died to replace. The second time was this past week, routine maintenance on the furnace/ humidifier system.
Again the technician was prompt, friendly and knowledgeable. We moved into a home with a 20+ year old system and explained how our humidifier worked, when we would need to change the filter, and tuned up the furnace. Never once tried to sell us something we didn't need. We will continue to use Greeley Furnace for our HVAC needs. Their staff truly makes the difference!

Called Greeley Furnace on 9/1 as my AC stopped working and they put me on the schedule to send out a tech that Afternoon. Received a text message that Mark was on his way and arrived at the scheduled time. He went right to work diagnosing the problem and quickly found the problem. He then reviewed the cost to repair it and approved the repair it. About 40 minutes from arrival to repair. Great job Mark. Greeley Furnace installed my furnace and AC 18 years ago when I built this home and this is the first problem I have ever had with the AC and only one minor problem with the furnace.
Because I have had a maintenance agreement with Greeley Furnace all these years and they come twice a year check out and service my furnace and AC I believe this why I have some few problems. Greeley Furnace is a reapable company and I would encourage you to contact them to do your repairs or when you need a new furnace or AC.

I have used Greeley Furnace for many, many years. Today I needed to have a new furnace installed. Keith was extremely helpful in helping me decide exactly what I needed. He did not try to persuade me to spend more. Today Richard installed the furnace. As has been true with every tech I have had to my home, he was very professional, friendly, and hard working. I would never use another company. Thank you, Greeley Furnace!

I was so thoroughly impressed with the service! My elderlyin-laws AC unit was in the end not salvageable. But.after doing everything they could to help, the owner, Scott, called me to say that while he's happy to continue patching it, we would just be throwing good money after bad, and that since it's still cooling, it's best to use it as long as they're able.he also assured me that it was safe to do so.
The honesty and integrity in that one phone call was what convinced me that in the future I would only use Greeley Furnace for any HVAC needs. We exchanged phone calls and visits for about 3 weeks total and throughout, I was made to feel like a person and a client that mattered, rather than as though I was just a number as so many companies these days treat their customers. Kudos to Scott and his team.other business owners could learn a lot from them.
