HVAC repair & installation in Uniondale, NY

Usually the heating system was designed for a floor plan that has changed. In Uniondale's older two-family and converted homes, one boiler or furnace often serves both units through piping or ducts that were never rebalanced. We look at the whole system, zone controls and load for each apartment before touching the equipment, because the unit that complains is not always the problem.

Quite possibly. In Uniondale, shared attics often hold two air handlers, and each has its own condensate line and drain pan. A clogged line or a cracked pan leaks onto the ceiling below. We trace which unit the water comes from, clear or replace the drain, and check that the safety switch actually works.

Conversions rarely get a new heating design in Uniondale. The basement is often fed by a branch sized for storage, or by nothing at all. Near Hofstra and Mitchel Field we see this regularly. A load calculation shows whether to extend the existing system, add a baseboard zone or use a small ductless unit.
