Airconditioning units are expensive, so if I'm going to purchase one and have them installed, I better make sure I hire the right company to do it. That's why I go with Hobart Air. Everyone I've asked gave great referrals, and I think that's the testament of a really great company: word of mouth testimonies. That and having experienced their service myself, I can see why. These guys are trustworthy, reliable and they get the job done quickly and cheaply. I highly recommend them.
