Would definitely use again.

Super informative me being a first time home buyer he explained everything I need to look for where leaks can come from. Showed me some air filters I didn't know I had that really needed to be changed. I highly recommend the COOLEST AIR Cliff was just a life saver for my house.

We would highly recommend this company and will not use anyone else.

They were very quick to set up both appointments, with the installation of the new system the day after Bart was over to give me a quote. The guys who installed the system were right on time, very friendly and were done when they said they'd be. They even swept up the dust in my house after putting a seal around the vents. Bart came back the next day to check on the system and to set up surge protectors on the equipment. The price was well under my other quotes and I really appreciated the "paid in full discount" they offered. I'm going to sign up for an annual service from the company as well. It is a hefty expense, but I'm happy with Ellis Air and I'm glad I decided to give my business to them.

I contacted Ellis Heating and Air in Killeen, TX in July 2025 to service my unit. The technician…read moreadded freon yet advised me there was a leak that he could not find, further advising that my unit was "cheap" and needed to be replaced. Feeling a bit insulted, we ignored his opinion and thanked the tech for his assistance. I called Ellis again September of 2025 because my unit again was not cooling. Ellis sent another technician, who advised again our unit was "cheap" and the compressor needed to be replaced, and we did not have a warranty. Ellis quoted $3200.00 to replace the compressor, or, $3600.00 for a new unit. We questioned this because we just purchased this home in 2022, so we researched our unit ourselves. We scanned the QR code on the back of our unit which immediately reflected a full warranty through 2031. I was able to contact the company who installed the unit. They immediately came out and confirmed the compressor had not failed but we had a clogged filter dryer. $150.00 later our "cheap" unit is working perfectly! CONSUMERS BEWARE!!!

I also said I would just like to price a new unit to see if I might, would be interested at some point in replacement. The man who called about the new unit was very pushy and when I told him that the estimate he gave was not in my budget for now and I would just repair my unit he got very pushy. Then, the technician who came out never called or came by again. He was also arrogant when he was here. Poor professionalism from him and the company. Never updated me on the part, and never even bothered to tell me they were not going to fix my unit. Got someone else, and it turns out it was not the parts that I needed. The only positive was when I called for service, the rep who answered the phone was very nice and got me scheduled quickly.

Upon arrival we mentioned what the problem was (broken outside water faucet valve) and he proceeded to check out the faucet. He went back to his truck and brought out the proper tools (2 channel lock pliers) only to find out he needed "the big guns." He brought a pipe wrench and immediately removed the leaky faucet and replaced with a proper one. We learned about the backflow preventer value and its history from Darren. He had that faucet repaired within 30 minutes. That was yesterday. Today he returned to replace our irrigation system supply line that had busted during last year's freezer. He cut out the old plumbing and replaced with a new one. He was very quick and pleasant to talk to. He did a very professional job and we will definitely hire him (his company) whenever the need arises. I would highly recommend Coryell Plumbing.
