They installed a replacement hvac system for us, very expensive. However, it only blows upstairs, not downstairs. They refused to honor their 'one year warranty.' They sent someone out to charge me $250 to do nothing. Follow up calls - they insist they have no idea how to fix our system and that it is not their problem that they obviously didn't install it correctly. They refuse to come out and fix it. Refuse to refund my money for the bogus trip charge. In short, if you liked getting scammed out of lots of money - this is the place.
