Purchased Lennox heating system. Immediately after installation Horizon replaced entire blower assembly to relieve whistling sound. Humming sounds remained. Would not recommend Horizon services if Lennox system is their choice for HVAC!

Your welcome Dave, as a customer I find that with any business you stick with what works and your business has high standards which is exactly what I demand in my home. In fact you guys just put in a whole new heating and air conditioning system, our second heat pump system with you guys in thirteen years. You also do plumbing work when we rarely need it. Keep up the good work. Your loyal customer...Chris

We have used Horizon Services many times in the past and have been very satisfied. However when we needed service for a drain clog recently, we were less than pleased. It was during the week between Christmas & New Years and when we called we were told that a service person would be available the next day. When the service person arrived and examined our issue, we were told that he did not have the necessary equipment and another service person was scheduled to arrive late the same day. Not too happy with that. When the second service person arrived and looked at the issue we were told that he scheduled a third person to rout out the drain. That would be the next morning. The third service person did arrive early and fixed the clog. The equipment needed was heavy drain router that had to be brought down our basement steps. Why didn't the second service person do the job while he was at our house? Too lazy to lug the machine out of his vehicle and into the house? We believe this issue took way too long to fix. Three service people and 2 days.

The techs are so professional, neat and clean. They will explain in detail what you need or what they did. I totally trust them.

The service is nothing what is advertised to be. Even though I'm a gold-service member and paid for it, we received anything but ""gold"" service. Horizon hides their ineptness and poor service behind a ""polite"" ""customer-friendly"" facade, which amounts to terrible service. Don't ever waste your money with them! Absolutely bad.

I got my new AC/Heater unit installed from horizon. After reading these reviews, I wish I read them first. I used horizon because they do always show up and you can get them pretty quick, but they are a little over priced. My problem though is not with the unit. I did have to call them twice to fix a brand new unit, but they fixed it and did not charge me. My problem is that they cut a bigger hole in my wall which they said that they would repair the damage. They have a contractor to do this work. I said fine. They never called to set that up, so I emailed the installer and then I got a call from Kim. The contractor then came out. He said he needed to come back. Fine. I got a call from Kim and I message that he needed two one hour appointments to get this done. Fine. She left me a voicemail. I called back and left her a message. No response. Called two more times and left messages and no response. I emailed the installer and the salesman and no response. I asked the last tech and he said that he would tell the complaint department and no response. I sent a service email thinking they would contact me and nothing. For what I paid I thought this would be simply, but no. Take my advice. Get someone cheaper and with the money you save you can hire a painter to get your whole house painted after the install.

UPDATE: Not sure how Dave G. intends to make this better, but so far, nothing has changed.
I received a call pm 12/4 and they changed my pm 12/6 appointment to am 12/5. The guy that came out (Greg) was very nice and spent a couple hours on the heater. He diagnosed it as a bad blower & said that the guy that came 11/12 (Mike) hooked up the electrical incorrectly causing the blower to go bad. He got my emergency heat working but had to reschedule to install the new blower that needed to be ordered.

Received a call 12/7 from Crystal in community relations. This is because I sent a not-so-nice email blasting their 100% satisfaction guarantee to my sales rep who forwarded it to her. After speaking with her, she scheduled my install for pm 12/9 with Greg. Who shows up 12/9...Mike - the same one that supposedly messed it up to begin with. After he installed the part, he informed us that we'd have to stay on emergency heat mode because the cause wasn't electrical but because of an inconsistency with the air flow and another appointment had to be made so someone could go under the house and check the vents. That appointment was made for 12/14!!! Here we are, 12/14, and I get a call that they have to reschedule due to ""inclement weather"" - it's raining. Mind you, it was raining all day when the unit was installed so why they rescheduled due to rain this time is beyond me. This time, it's an additional FOUR days I have to wait...scheduled for 12/18!! We are supposed to get snow 12/16. Are they going to reschedule again due to a mushy ground?

So from 12/4 - 12/18, I am having to use emergency heat. Which we all know will skyrocket your utility bill!! While I got verbal support from Crystal that they'd help with my bill, I still get the feeling that they really do not care if their customers are inconvenienced in any way.

Dan was our Tech today and he was outstanding! My furnace stopped working this afternoon, I called Horizon and told them what was going on and they said they could have someone out here by this afternoon. They gave me about a 30 minute notice before someone came like they said they would. Dan showed up, immediately diagnosed the small part my furnace needed. He was very friendly, professional, honest and knowledgeable. He gave me some tips on keeping the furnace tuned up, and showed me the error codes on the furnace, which I really appreciated, I also appreciated the quick response. I called Horizon at 315pm today and someone was here a couple hours later, the day after Thanksgiving, very impressive!

Thieves! Said a 4 year old furnace had a cracked heat exchanger and the control board was fried. Was told replacement furnace would be $7000. I explained that I did not have that much and was then asked ""what can you do today"" and 'I could use a sale today"". Really?? After this, I called 2 other companies and neither found a crack and the board was just throwing codes but had power. They try scare tactics to get a huge sale. Was informed by many people that this is the norm for them. Needless to say, I needed a new board for $400 installed (Horizon was $900 for same part). I don't know how they are still in business after all the complaints I have come across. Terrible company!!!!!!!!
