We tried contacting Arties for them to rectify the situation and their office manager was very rude and unprofessional. Id recommend buying more fans if your only option is Arties. And they apparently can remove their low reviews so go to yelp

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!!!

I have come to value his skillset and his accurate diagnosis of the problem at hand. He has always been prompt in keeping his appointments; and prompt and accurate in troubleshooting and resolving any issues. He has always been upfront and honest with me when assessing the issue at hand and he has always quoted me a price on parts and labor before he starts any work. He has never exceeded the initial quote once the work has been completed. (Even if he has had to "eat the cost" himself.) I find 360 Reliable Air Services to be just that... RELIABLE. He has about 25 years of experience in his craft and he has always gone above and beyond in servicing my HVAC unit! I believe him to be a man of integrity and I highly recommend this service.
