I have been using Airplus for many years, and they have always provided great service. The technicians and office staff are always professional and courteous. Just few days ago my AC totally broke down. Due to the extremely hot weather, I was in a really tough spot. Thankfully, Joe and Tatiana went the extra mile to quickly arrange all possible logistics and expedite the new AC unit installation. I really appreciated their fast, competent service and clear communication. Their work really showed me how much they care about their customers.

Everything about my experience with Air Plus was top notch. Tammy was fantastic at answering all of my questions, and if she didn't know an answer, rather than fake it, she took the question offline to her experts. Joe did a really thorough assessment of the issues we were having and was great at helping me to intelligently select the right equipment for our home. And Air Plus's crews were absolutely incredible!

They arrived and worked all day to replace both of our HVAC systems (they were well beyond their useful age). One of those systems was in our attic, and it was 90+ degrees outside that day. As I already stated, they were incredible. And now, we are enjoying the cool air from our new HVACs, which Air Plus flawlessly installed.

Justin Patton came by the house to give my a/c units their annual checkup. He was extremely knowledgeable and genuine. Not only did he walk me through all of his checks as he went along, he also took the time to answer all my general questions about my system and the goings on in the industry. Great guy. I've had nothing but good experiences with this company for the last year.

We had a ductless mini-split AC unit installed in our home office yesterday and love it! The sales person clearly explained our different options available and we were able to get a quote immediately. The installation was able to be performed quickly, with very high quality, and with minimal disruption to our work day (we both work from home). Would definitely recommend.
