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!

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!!!

He also knew what we needed to do to improve air intake to the main unit. I wouldn't have any other tech other than Tyler (unless he is unavailable), or another company work on my heating and air conditioning needs from now on. The price was reasonable and I'm highly satisfied with the quality of service. Deborah E.

After Multiple times calling I was told the reason they were late and that My appt was pushed back. Now it is 3:00 pm and i have left another message to see what is the status and nothing. I find this unprofessional and i should have not taking a chance to try them out. Lesson learned. They arrive at 4:14 pm and they did a great service. Made an extra value for me so i can pour bleach down the value for my own maintenance. They also explained to me what future issue I might be having which I appreciated. For their work I change my 1 star rating to four. I give it a four because I was not told the price when i called.

If you have American Home Shield which is a great service. Please if they assign you to Arctic Air…read moreService & Maintenance, call them back and say NO THANK YOU ask to be assigned someone else. They assigned this company to use a week ago, told us to contact them and make an appointment. I call to make the appointment after the 4th of July holiday, the following Tuesday and was told I could not make an appointment that the contractor would call me when they got to my number or place in line, that's fair I thought. Mine you they never ask who I was or what the problem was. I ask if I could tell where I was on the list and they said that they had no way of knowing, strange. Now I am worried because you have no idea who we are, what our problem is, and did not seem to be bother with taking down our information. I have used American Home Shield for years and never had this problem. We called back and was told that everyone wants their AC fixed right now and was left in awe at how it did not seem important to this so call company that we are in triple digits here in Texas, with a home that is at 95 degrees inside, which is why we are concerned. Not to mention that there are medical reasons to worry about as well. This was just the first two days of calling in which we did understand that others may have been in the same situation as we were in at the time. We just wanted to have an idea of the possible timing so that we could make plans to safe guard our family from the heat and no AC. However, we could never get anything from Arctic Air but "I can't tell you when and that they were working on AC issues that were overdue, due to the 4th of July. American Home Shield assigned us to them on July 1st at 11pm that night. We called back on day three and was told that they would contact us in 24 hours, never got the call. When we tried to call back after the 24 hours they no longer picked up. On July 7th My husband call American Home Shield and reported the issue and they reassigned us someone else with hopes of getting us help right away at this point. With all of this being said, I would have like a disposition from Arctic Air, letting me know up front that it may take a week or two to get to us. Instead I was waiting daily for information that I never received. They did not seem to be prepared when they were assigned this contract through American Home Shield. As of today, I found out that a good number of people have recently had problems with Arctic Air in Copperas Cove Texas. I am just happy that American Home Shield took the contract back and reassign us. Do not use Arctic Air Service & Maintenance in Copperas Cove Texas its not worth it.
