I was having issues with my air conditioning system blowing hot air, so I reached out to Grays Heating and Air Conditioning in order to get it fixed. The technician who showed up was very knowledgeable and professional. He diagnosed the issue, which he discovered had to do with my thermostat, and although he wasn't here long he figured it out and took care of the problem. This was my first time using their services after finding them online and reading reviews from others, and I would consider them again.
