Furnace is on but blowing cold air from vents. Long Island Climate provides fast, reliable heating repair service throughout Franklin Square and Nassau County.
📞 Call 516-643-4486Franklin Square is a hamlet in Hempstead Town named in honor of Benjamin Franklin. The community's central location in Nassau County and its post-war housing stock means many Franklin Square homes have aging HVAC systems that benefit from regular professional service and modernization. Long Island winters bring freezing temperatures, coastal winds, and occasional ice storms that push heating systems to their limits. For Franklin Square homeowners, a reliable furnace is essential from November through March, and Long Island Climate is the trusted local heating expert serving Franklin Square and all of Nassau County.
Cold air from a running furnace usually means the pilot light or ignitor has failed, the gas valve is closed, or the heat exchanger is cracked.
Check that the gas valve is in the open position. If the furnace is still blowing cold air, call a technician — a cracked heat exchanger is a carbon monoxide hazard.
Every Franklin Square 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.
When you call about Furnace Blowing Cold Air in Franklin Square, tell us what changed first, whether the system is still running, and if you noticed ice, water, odors, unusual noises, breaker trips, or weak airflow. These details help us arrive prepared and protect the equipment from further damage.
Call a technician immediately if you smell gas, see a yellow or orange flame, notice carbon monoxide detector alerts, or if the furnace will not start after basic troubleshooting. For Franklin Square residents, Long Island Climate is available same-day and 24/7 for emergencies — call 516-643-4486.
