The usual suspects are a dirty air filter or coil choking airflow, a failed capacitor stopping the compressor or fan, a refrigerant leak, a frozen evaporator coil, or a thermostat that lost its signal. Any of these will make an air conditioner run without cooling. Our AC repair in Princeton visit starts with a full diagnostic so you pay to fix the cause, not the symptom.
Confirm the thermostat is set to Heat with fresh batteries, check that the breaker and the furnace power switch are on, verify the gas valve is open, and replace a clogged filter. If the unit still will not fire or it lights and shuts down, stop there and call (877) 257-2196: repeated ignition attempts can lock out the board. Details on furnace repair in Princeton.
Almost always a blocked condensate drain, a full drain pan, a failed condensate pump, or a frozen coil that is now melting. Shut the system off to limit water damage and call (877) 257-2196 - this is a fast, inexpensive fix when it is caught early.
All major residential brands, including Carrier, Trane, Lennox, Goodman, Rheem, Ruud, York, Bryant, American Standard, Amana, Daikin, Mitsubishi, Fujitsu and Payne, plus builder-grade units common in Princeton developments.
