    Our EXTREME MAKEOVER Experience

    Extreme Makeover: Home Edition is a home renovation reality TV series devoted to rebuilding homes and buildings for people in need. All materials and labor are donated, for the interior, exterior and landscaping, and construction crews get it all done in only one week.

    Hardy HVAC was selected to install the HVAC systems for the Lutz family house in Setauket. With a crew of 25, two complete systems were installed between midnight and 11 AM.
