BEST company, Awesome service, Extremely professional and NO Regrets hiring HORIZON AIR CONDITIONING to install my brand new air conditioner. The owner Dave was super nice and very knowledgeable. No big sales pitches and just an honest guy running an honest company. His crew came out on time and did a perfect job. No mess what so ever to clean up and couldn't be happier with everything from start to finish.

These guys were spot on from the minute they arrived until they left. We are doing a lot of remodeling on our home so I have much experience dealing with everything that comes with contractors and companies in my home. I highly recommend HORIZON AIR CONDITIONING to anyone that wants a no hassle, no stress, quality install. Hope this helps you and by the way, I'm sitting in my nicely air conditioned house writing this review.

We recently called Horizon Heating & Air Conditioning, Inc. to install a new HVAC unit and clean the furnace. Their approach towards the entire process was very professional. They explained everything they were doing and answered all of our questions. Their charges were also very fair. Would definitely recommend them.

Dave the owner came out to our house and gave us a complete assessment of the air conditioning and heating which was not working at all even after the prior contractor had replaced both units. His estimate was the lowest of the five we got. His guys were knowledgeable and worked hard. He gave us quality materials and didn't charge us a dime until the work was done. We were very happy with his services and give his company an A plus. Jasmine in Newport Beach
