When further problems arose with the heating element, he meticulously troubleshot it, fixing issues along the way. He is clearly knowledgeable and maintained all of the replacement parts on hand, so he could fix the issues quickly. He fixed the issues in less than two hours, and the HVAC is running perfectly. Would definitely use again.

Very pleased with Ellis after having to replace my entire heat pump unit. I got quotes from two…read moreother companies in the area and went with Ellis. 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!!!

Found these guys and tho it was complicated (due to the builders lack of knowledge) and very time consuming they did not give up, came back again and again until it was fixed.

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

I worked with about six or seven companies and decided on Killen Heating & Air Conditioning. Josh offered the best fit for my wants at the best price by far and wanted to work with me to see my project get done. His crew came out and were able to quietly remove my old system and keep the area clean. They got to work on installing the new system and kept me informed of all that they were doing. My dog was interested and they even reassured him and made friends. I'm truly happy that I chose this company - I'm looking forward to continuing business with them for the foreseeable future. They did a great job and befriended my family doing it. I definitely and highly recommend them for anyone with A/C issues!
