My husband did heating and air conditioning for the state of Delaware for many years, so when we needed a new AC/heat pump he researched many companies. He finally decided on Air Doctor x, owner Mark.
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.

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.

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!

The crew was great to work with. They were very helpful and knowledgeable of the system installation. They also were on time for scheduled times to be completed. I would recommend air doctors to my friends and family if they ever need this kind of service.

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
