A/C Masters Heating & Air Conditioning Inc

Description of Work: They gave me an estimate for some insulation work. They seemed to be pretty good and knowledgeable but I have not used them yet.

Description of Work: originally, one of my household A/C units stopped working (came with a new house and was 8 years old). A/C masters got the compressor running and checked the charge. They told me to see if it would begin cooling after a few hours. Due to a couple of days where the temperature dropped, it took a bit to realize that it was not working properly. Replaced the unit with one supplied by A/C masters, after doing a lot of on line research and making some calls of my own to other companies. I hired these guys originally because of the 'A' rating on Angies list and was not disappointed. Despite having to replace my unit, I think I got a good deal as well as a number of professionals to install it.

Description of Work: Heat pump pressure kept getting too high, causing me to have to repeateldy reset the pressure cutout switch on the outside condensor. Called the company at noon on a Saturday, and technician was at my house only 2 hours later! No extra cost for weekend service. Before arriving, technician and I spoke on the phone where I described the problem. He offered suggestions on things I could do to fix the problem myself in order to save me some $$, but I had already done what he suggested so a service call was necessary. Technician was as professional as they come, and competent. He first checked the air intake to ensure filter type was not restricting airflow. He then went in the attic to inspect coils for cleanliness, and they were clean. He then explained that thelikely cause was a refrigerant overcharge. He hooked up his meters to the outside tank and all the while explained how he was conducting his diagnosis. He determined that the system was overcharged, explained how he determined this given all the readings he was taking, and purged the excess coolant.
