Troubleshooting Your Heating System When It's Blowing Cold Air
Whether you use a heat pump, gas furnace or boiler for heat, you count on your system to keep you warm during the cold months. If your heating system is blowing cold air, there are several things to check before calling a professional heating, ventilation, and air conditioning contractor. Some components are common to all systems, including filters, ducts, thermostats, fans, and electrical connections. Each system also has unique components. Here is what to look for to troubleshoot heating problems.
Check Filters
Dirty filters are the most common reason for poor performance. Filters capture airborne pollutants and keep them from entering ducts or being blown into your living space. When filters get dirty, equipment must work harder to produce conditioned air. Eventually, the unit stops working. Clean or change filters according to the manufacturer's instructions. If you live in a dusty area or have pets, you may need to service filters more often.
Check Thermostat
Be sure the thermostat is set for heating. Check temperature settings, and clean the unit. Replace batteries if needed. Make sure the thermostat is not in direct sunlight or next to appliances that generate heat.
Check Electrical Connections
All heating systems have electrical connections and components. Check breakers and switches to verify the system is powered. Frayed wiring and poor electrical contacts can affect performance. Major electrical problems are best left to professionals trained to repair them safely.
Inspect Vents and Registers
Blocked or dirty vents may restrict airflow. Make sure furniture, draperies, or carpets are not blocking vents. Clean registers to enhance airflow.
When to Call a Professional
Heat pumps use refrigerant for both heating and cooling. Improper refrigerant levels can affect heating performance. A professional should inspect and clean pilot lights and tubing on gas and oil furnaces annually. Seasonal tuneups inspect each component of a system to make sure they operate properly.
