Why Is My Heater Not Blowing Any Hot Air?



There are a number of reasons why a heating system won’t blowing hot air. An exact answer to this question may not be available until a trained service technician has inspected your equipment. However, there are a few things you can verify before scheduling a repair call.

Replace the Filter

The filter is an important layer in a heating system. It helps keep dirt out of the equipment. When you don’t change the filter every month, it gets clogged. A dirty filter stops airflow and can overheat the system. The team at Gilmore Heating, Air, and Solar can assist you with a broken or overheated furnace in Placerville.

Check the Pilot Light

Pilot lights can blow out, and the indoor air will turn cold quickly when the flame goes out. Relighting the pilot light can be a tricky process, so only light it if you know how to do so safely. If the pilot light goes out repeatedly, call a technician to inspect it. A part may be damaged and need replacing.

Schedule Maintenance

When a furnace system hasn’t had maintenance, it gets very dirty and can stop working properly. A dirty furnace can struggle to deliver warm air, and your house can become cold quickly. It’s time to call the experts for a system tune-up. A maintenance visit will include testing, cleaning, and calibrating your equipment.

Verify the Fan Setting

If you’re experiencing cycles of hot air followed by periods of cold air, check the fan. The fan setting should be on auto. The auto setting ensures that the blower works only when the furnace delivers hot air. When the fan is set to the on position, the fan blows air all the time whether it’s hot or cold.
