What our customers Are Saying About Us
EXTREMELY AFFORDABLE Compared to Horizon Services for the same route, the work carried out was very professional and well prepared, very clean there were no complains at all. Installed a completely new system in a day.
– Andrew Edington
We had some concerns about a rebate but Mark went over and above to help us qualify for the rebate. The installation process went smoothly and was done in less than two days. We would highly recommend Air Doctor x.
– Dianne Moore
Prompt, professional, and great problem solvers. Even when a challenge presented, they successfully Plan B’d the project and finished the job in a timely manner before a major snowstorm hit. Kudos to the team and thank you for your top flight install and service. I could not be more pleased!
– Marisa Trasatti
They upgraded my thermostat so my heat pump would work. The system was AC only until then. Ken was very thorough and explained the work when he was done. Steve followed up the next day. They’re always friendly, helpful and reasonable. That’s why they’ve handled my heat and AC systems in our rentals and primary home for years.

Our Special Promotions Offers
Breathe Easy Now, Pay Over Time
You work hard for your money — don’t let an outdated air conditioner drain it. Replacing your HVAC system might feel overwhelming, but it doesn’t have to be. With our flexible financing options, you can enjoy the comfort you deserve without stretching your budget.
Why You Need a Summer AC Tune-Up
At Air Doctorx Heating & Air Conditioning, we take pride in being involved with the community. One of the most rewarding projects we’ve been a part of was helping to donate and install high-efficiency air conditioning systems at a local family resource center. The center serves hundreds of families throughout the summer, and we were honored to ensure that children and families would have a cool, comfortable space during the hottest months of the year.
