I have used A/C Masters Heating & Air Conditioning Inc. a few times. Every time they have been out they arrived on time, were very pleasant and they know what they are doing. On the last visit, they had to replace the fan motor in my heating unit. It did not take long for them to replace it, had the part in stock and the unit has been working perfectly since that repair. I think for all the visits that they have done for me they have done a good job and I would recommend them.
