This company is wonderful! They're very easy to do business with, and I would definitely recommend them. I used them for the first time, to install an AC, and shortly thereafter, because my furnace (which they did not install) was making a strange noise, late in the evening. For the furnace, they had a technician over in less than half an hour (at night!) and she was wonderfully gracious about fixing a problem that wasn't even hers, or result of her company, in the first place.
The AC installation, as well, went flawlessly well and I was very satisfied with their service. They're very up-front, explained everything they were doing, and didn't do anything that they hadn't said they would. I really appreciated how communicative they are, and would definitely use them, again.
