A selection of 646 homeowner reviews:
“I had an initial problem with the initial installation and received no satisfaction when I spoke to the tech responsible for the installation. After speaking to an office staff member the complaint was fixed to my satisfaction.”
“Courteous service top to bottom. Do good work.”
“They did a very good job but did forget a few things that they needed to come back to do. The first one was not a big deal but the second one was they did not cap off gas line in attic. Would not have known if A/C service would not have told me. I don't climb in my attic. So far those are the only things I have been aware of at this time.”
