This company comes highly recommended from yellow pages . com which I can say they are highly referable in my eyes from the beginning of summer my A/C had not been running good I saw the outside unit frosting up and realized I better call somebody quick, I used a company in the past that I had a terrible experience with so I wanted to change who I had been using I went on to yellow pages.com to see some of their reputable companies I was calling around and found some companies were not able to respond as well as bad customer service I called Doctor Plumber after the third or fourth phone calls and found their company to be the top company with their response service same day service I was pleased at that it was a Saturday they had the stock on the truck and were able to get the machine running better than it was running from the beginning of the summer also very clean gentleman looking technicians they never even batted an eye lash to go up in the attic to fix a start component that was making a smell it was 140 degrees up their and he was working for twenty minutes up their my last guy used to go up their and come down in two minutes Panting and sweating and cursing these guys were very professional in my eyes.I thank you for the great service Allen Fitzgerald and family.
