We Install the Best & Fix the Rest!
Since 1968, Weber & Grahn Air Conditioning & Heating’s mission has been to create comfortable and clean indoor environments with the highest precision, professionalism, and integrity.
We install the right system each time – from a connoisseur’s precision wine system to an HVAC unit so perfectly engineered and installed you forget it’s there. And when it comes to service, depend on the technicians at Weber & Grahn Air Conditioning & Heating to bring you spot-on repair and maintenance. Our computerized service vans arrived with stocked parts for Carrier, Trane, Bryant, Lennox, York, Rheem, and Mitsubishi, along with many others.
Located in Hampton Bays, we service throughout the east end of Long Island, including the areas of Southampton, East Hampton, Riverhead, Smithtown, and many more.
