Emergency Saturday call as AC outdoor unit wasn't running. We thought it was the capacitor do to the numerous brownouts. Service felt like a SALES call not a service call. He should have known that the unit could have gotten too hot and shut off until it cooled down due to the brown outs. It was working when he left( came back on on it's own)Two other companies have said this is normal during multiple brownouts.

Definitely a pro company. Our business HVAC died at 1 AM. They were out by 2 AM and had it fixed within 30 minutes. Our tech Robert explained everything in detail, I would look no further should you require a service company. Service: Repair HVAC

I called in the morning because I was having trouble with my unit, and they set up a service call. Bobby came to look at my A/C, identified the problem and fixed it on the spot. Bobby was very helpful and professional. Service: Repair HVAC

Used this company to install new furnace. They sent a rep to measure opening and to determine what options I had. They wrote an estimate on what would work for me. I approved the estimate for a Coleman furnace. They installed the furnace on scheduled time. When they tested it. It did not work. The tech called Coleman on what could be wrong, they told him it needed a special flue pipe. He ordered the pipe and scheduled a time to install it.
When that time came no body showed up, so I called them. They told me the pipe didn't show up. The next they rescheduled the install. When that day no one showed up. I called them again and they told me they would track it down. At 11AM they called me back and found it in a warehouse in Harlingen. Since we have been without heat for several days and the nights are in the 30's I told them ASAP. They did a wonderful job in setting up the install that same day for 3PM. After installing flue pipe the furnace works GREAT! They cleaned up the roof and furnace area before they left.

Great service, very friendly and professional. They cleaned our heating and ac systems as well as cleaning AND sanitizing our duct work. I was shocked with the difference. The sales and tech folks provided us with before and after pictures. I really liked the fact that they carefkully cleaned each register and duct while masking off all the others. This really guaranteed none of the gunk they where cleaning escaped into our home. All this and they finished in just a few hours. They are NOT cheap, bit we felt it was well worth the price.

Our AC unit needed attention and we called the George Cunningham company. I was told that Danny Garcia was on his way. He was prompt and quickly diagnosed our problem. It was fixed and he was on his way. He was very professional and personable. I would recommend the George Cunningham company! Service: A/C system maintenance

There are not many Home heating repair companies in the RGV (home heaters-those installed into a homes wall-not part of the installed A/C). Glad to have found one that was close by n had an open appointment. Repair tech was on time, professional and able to find the problem and repair it in one visit. Will use again, hopefully not soon!
