Horizon Services Plumbing, Heating, and Air - Denver

David, Jonathan, and Carolyn were great to work with. All were very professional, arrived on time, and didn't leave until all my questions were answered. I hope they gave me a competitive price on my new furnace and water heater and plan to call in the future for my annual maintenance inspections.

This was a rather interesting experience. I had non-emergent issues with my boiler. The guys came out, and recommended a maintenance service so they could, “go through everything and find the problem.” I hadnt had it done, so I agreed. It became clear that my unit was being used as a training exercise for a new guy. When they were done, I was assured that the leaking gauge was just a temporary fluke, the parts expand and it’s not leaking now. Weird. On top of it, they charged the expensive trip fee even though they had done a service. Better businesses dont do that, in my experience, but I’ll take the blame for not asking in advance. If I had, I’d probably have sent them away without doing any work. I started the boiler the next day, and of course it started leaking again. I called to complain, and they told me it was tough luck about the trip charge but they would generously waive the next one if they came back out again because of an issue with their work. I wasnt going back for a second burn, and I paid another company to do my repair. Caveat emptor!

I've been using Horizon for over 6 years now and I've been extremely pleased with their service. We are on their maintenance plan so that they service our home twice a year. They do excellent job in keeping everything running in top capacity for our home.

Buyer Beware. This company is disreputable and will absolutely price gouge you. I contacted them for routine maintenance on my HVAC system in my 600 SQFT Condo. They told me that the entire HVAC unit would need replacing, and they quoted me $15,000-$20,000. Reasons cited were low Freon levels, internal rust to the system, and a failed stop-safe mechanism.

Some of you might be unfamiliar with HVAC systems, as I was, but that price is absolutely absurd. Initially I had sticker shock, but I was not schooled enough on HVAC systems to know if their price was fair. I did my own research and found out that a unit for a 600 SQFT apartment should cost ~$3000-6000 with labor. I called Horizon back and told them about my research, and they immediately started making excuses about their prices, trying to justify it with professionalism, high quality, and "precision measurement" (lol $10,000 for a tape measure).

Fair enough, but when Im spending $15,000, I like to know exactly what Im buying. I asked for a detailed breakdown of labor costs, parts, etc. so that I could see what I was paying for, and they said "oh, yeah, we dont do that". How ridiculous! Imagine going to a grocery store, not knowing what you're buying, and not being able to get an itemized receipt.

I got a second quote from another contractor. They told me that my Freon levels are exactly where they should be, that internal rust happens normally and can be cleared out, and showed me that my stop-safe was working by demo-ing it.

I asked the second HVAC professional what he would charge if I needed the entire unit replaced (which he advised against), and he said it would cost no more than $6000, and that's if I let him have free reign to put in a state-of-the-art unit.

Again, buyer beware. The folks they sent out were very nice and professional, but this company is predatory and looking to take advantage of inexperienced homeowners and people without HVAC knowledge. They should be ashamed.

1) When I called I indicated that the house had an older furnace, 20yo approximately. Asked if they would recommend replacement over repair. They indicated that if furnace was in good repair, they would repair. I authorized service visit based on this.
2) Tech arrived at house. Nearly turned out.
3) Incorrectly identified fault as it later turned out, BUT when I asked about repair he indicated that they will not repair any older furnaces and would replace furnace only. This was seemingly in contradiction to point 1. When I questioned tech he indicated that this was their policy. He said older furnaces were inherently unsafe but could not explain even in general why
4) Waste of service fee. Furthermore after some youtube videos and a multimeter it was apparently he really didn't know how to troubleshoot the issues.
5) Following this experience, I felt that they were only interested in the possible sell of a replacement furnace and not in troubleshooting or repairing the existing unit.

Horizon Services personnel are well trained and thorough in their work. I find this company reliable and efficient, good communication and complete explanations about the work that was done. I believe the rates are competitive. Horizon services my furnace, water heater and air conditioner. There are other services available which I have not used.

I've been a Horizon customer for several years, and have always been happy with their service. Although they're not always the least expensive option for HVAC products & services, I'm always impressed by the level of service they provide.The techs are on time, knowledgeable, do a great job, and explain fully everything they've done.

Keith was in communication before his arrival. As always, all techs have clean uniforms, shoe covers - very professional. Keith even asked me - "I will be going in and out a few times - would you like me to knock or just come and go as needed?" NICE! He spent some time after service to go over our system, its age, maintenance options, etc. NO PRESSURE - just giving me information. Now I have some items on MY radar for future decisonmaking! Great work Horizon! Your crew is exceptional!

We have worked with Horizon for years. Simply put - they are great! They reach out to us when it's time for our checkups, they always show up on time, and they also take the time to explain things. I highly recommend the team at Horizon!

Refused to discuss or look at new Heat Pump (Geothermal) unit. Low pressure switch is either bad or unit has a small refrigerant leak. I have pressure switch coming from manufacturer, it’s a $5 dollar part. Owner said he doesn’t work on homeowner provided units. I’m a general contractor and didn’t have a chance to even tell him this. He said he would be happy to replace entire unit... That’s funny ! Funny thing is I have (4) single family homes I’m building in 2021 and my HVAC contractor retired in the past year, I’m looking for a good company to do my work and be responsive. Homeowners beware! Never judge a book by it’s cover, Sir! Big mistake!!!
