I've had Hendrix Air out to the house to do just about everything. They installed a new heat pump for us. They also replaced all the mechanisms that go along with it. They put in a new blower. On top of all that, last week I had them go over my duct work. They found some holes, so they repaired them. They put some of that sealer stuff on them. I been satisfied with their services so far. Everything's been on the up and up. I'd recommend them to my friends.
