They gave me an honest appraisal without charging for unnecessary tests, and did the installation quickly, in the middle of an epic heat wave. They might be newer than some of the other folks around, but they are building a stellar and well-deserved reputation. Dont hesitate! (At seven months, had a service call that went smoothly and was pretty economical!)

Tim help me install an in-line fan boost the AC onto the second floor. During the summer it gets so hot on the second floor that I can barely be upstairs. Now with this remote Wi-Fi controlled in Line fan extra air condition received from upstairs makes it so nice. Great service. They were very prompt.

Orion HVAC saved us when our HVAC blew up during a heat wave. They came out within two hours of us calling them, and then returned a couple of days later to do a complete replacement. Very professional and they explained what they were doing very well. They also coordinated the permitting process quickly and smoothly. Highly recommend!

My tech Feliks was really helpful. I had to leave and run an errand and he made my wife feel comfortable with the work he was doing. He was professional and pointed out a simple solution whereas another company didn't see the problem and told me to replace the whole unit. He explained things in simple terms and was thorough.

I had put off having work done on my defective thermostat until the original employee of Orion was available for a follow up replacement service. As it turned out he was NOT the one who DID show up on the delayed scheduled day. The man who DID come out was another man but he did a fine job. Just it could have been sooner but I thought it best the original guy come out. No matter

My air conditioner stopped working on Aug 5,24 so I called HomeServe and they made arrangements with another company. That company never showed up. So I called HomeServe this morning 8/6/24 and they made arrangements with Orion HVAC. They said that they couldn't come today, I told them that I take care of my 81 yr old mom and that the temperature was 90. They said that they would be here by 4pm. And they were. The technician was very nice and fixed the issue. Thank you Orion HVAC for taking care of my family. I will let everyone I know, how wonderful you are and how much you care about your customers. Thank you again for all of your help

Victor was the technician that came out to do maintenance work on our HVAC. We had recently bought the home and wanted to just get more information on the unit while also getting it serviced. Victor was on-time, nice, professional and gave us all the information we needed on our union. Yury, the business owner, was also prompt & professional when I initially inquired about services.
We'll definitely be back for future service with Orion!

Water was leaking from the ceiling. I suspected that it was a clogged drain from the HVAC unit in the attic.
When Victor (technician) came, he looked around and determined the issue and went to work. Then he briefly explained to me the cause and the condition of the unit in the attic. He made sure everything was working properly. He was very professional and quick!
I appreciate his honest assessment and honest pricing! Thank you Orion HVAC!

Victor was great! He was in and out with the problem fixed within 30 minutes. He was very knowledgeable and answered all of my questions. I was set up with Orion through my home warranty and they gave me a call immediately to set up the service for two days later. Overall, very happy with the experience.

Great experience from the start. This is my 2nd time receiving service from Orion HVAC. I called today about my broken heater. The person I spoke with over the phone was very helpful and was able to get me on the schedule for the same day. Feliks was the technician that came out. He was very professional and got the job done quick. He was informative and even shared tips to maintaining my heater. I was also working while he was here and he was so patient with me while I took calls. Great service overall. Thank you Orion HVAC.

Alex was on time, professional, and knowledgeable. He got right to the root of the problem with my HVAC. Cleaned out the system. It was filthy. Changed out some parts. He showed us the parts he was exchanging and explained why. He suggested we update the system with new thermostats and we will take his advice. Everything was done in one visit. Everything was explained and priced accordingly. We were very pleased with the work done and how well our system is now working. I highly recommend Orion HVAC.
