Shady dealing and shoddy install
Del Air installed my units in Dec 2017 and I moved in after closing in June 2018. They were out twice for service between June 2018 and March 2019 for shoddy install repairs. When I called to have service and found the "45 day card" hidden in the unit behind all the paperwork, not displayed anywhere anyone would find it, and called DelAir to ask about registering the unit, they stated it was too late. Another friend of mine who does AC said this was false and I was able to register the unit with Carrier directly, albeit Del Air's lie. Their install was shoddy, their service horrible, and their lies, despicable.
