Many of Malverne's historic homes require updated HVAC systems to provide modern comfort while preserving their architectural character.

Defrost cycle, low refrigerant, or a failed reversing valve causes a heat pump to blow cold air in heat mode.
A brief period of cool air during defrost cycle is normal. If cold air continues for more than 10 minutes in heat mode, call a technician.
Every Malverne service call is a little different because home age, insulation, equipment location, duct design, and daily usage all affect how an HVAC system behaves. Nassau County homes often have tighter mechanical spaces, older ductwork, finished basements, additions, and mixed-age HVAC equipment that need careful diagnosis.
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.
