Look below to hear why customer choose AC Doc for their heating and cooling needs

I have been using AC Doc for the past 5 years for my HVAC servicing needs. My initial service calls involved maintaining and extending the life of an aging HVAC system.

In addition to normal maintenance and servicing, AC Doc on at last two separate occasions identified non-HVAC problems that were causing my HVAC system to operate abnormally or not at all.

In one instance in particular, AC Doc went the "extra-mile" by taking their testing beyond the HVAC system to the main house electrical panel and diagnosed the problem being a loss of power entering the house. AC Doc informed me exactly what the problem was, who needed to be called, and what they needed to be told to resolve and fix the electrical problem promptly. Their professional and knowledge helped fix the problem promptly as well as put my mind at ease.

Since that time, I finally replaced my 18 year-old HVAC system and once again used AC Doc. I appreciated their professional and knowledge that was demonstrated in discussing my HVAC system options and selecting the proper system to work with my house. I will gladly continue to use and would recommend AC Doc to other homeowners for their HVAC needs.

My wife and I have found A/C Doc to be a trustworthy company over the past ten years. A/C Doc installed our current gas furnace and central air conditioning and have kept them running efficiently ever since through their annual preventive maintenance contract. A/C Doc technicians are knowledgeable, professional and clean. When our HVAC requires upgrading or replacement, we will be calling A/C Doc.
