Low refrigerant, a failed reversing valve, or very cold outdoor temperatures reduce heating performance in ductless systems.
Check that the unit is set to HEAT mode. In extreme cold, heat pump efficiency drops. Call a technician if heat is insufficient in moderate temperatures.
Every Port Jefferson Station service call is a little different because home age, insulation, equipment location, duct design, and daily usage all affect how an HVAC system behaves. Suffolk County homes often deal with longer equipment run times, larger layouts, coastal humidity, and seasonal temperature swings from the South Shore to the North Shore.
For heating problems, we check ignition, safeties, thermostat demand, burners, blower operation, venting, fuel supply, and whether the system can run safely through a cold night.
