Our HVAC division has its own sheet-metal shop with computer-guided plasma machines and a highly qualified and experienced PE capable of reviewing plans and designing systems. In other words, we can handle it all – plumbing, heating, and the mechanical work – competitively, efficiently, and effectively. You have one phone number to call, seamless coordination of the different trades, and one company to quickly resolve any problems that might come up.


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.
