Homeowners in San Francisco, San Mateo, and surrounding cities often experience common problems with their furnaces come winter months. Although our area doesn’t typically experience the frigid temperatures those in northern states often face during the winter season, you may still have problems with your furnace at the most inopportune time. When temperatures drop, you may turn on the furnace for the first time this season, and find it isn’t functioning properly. Below are a few troubleshooting tips we think you may find useful. You may be able to address some of these furnace issues without the need to call a professional HVAC technician.
Furnace doesn’t come on. In this case, many times the pilot light may be out, or the batteries in a programmable thermostat are dead. In addition, the electronic ignition system may be malfunctioning. If you’re comfortable doing so, re-light the pilot light or replace the batteries if you have a programmable thermostat.
Power issues. Is your furnace switched to the “on” position? Check the circuit breaker to see if it may have tripped, and reset if necessary. Also take a look at electrical connections to ensure your furnace is hooked up properly and receiving electricity. If your breaker continues to trip, it’s time to call in the professionals.
Not getting heat? Check the thermostat to make sure it’s set at the appropriate level; kick it up three or four degrees to make sure it comes on. Also make sure your thermostat is set to “heat,” and not turned off or set on cooling.
Airflow issues. If it seems you aren’t getting sufficient airflow, check to make sure air registers and vents aren’t blocked by objects such as furniture or boxes. Also take a look to make sure dampers at vents are open, and that the pipes in the duct work are securely connected to air supply vents. If your filters are dirty or clogged with dust, pet dander, dirt, or other debris, it can prevent air from flowing properly. A clean air filter will allow for good airflow, and also improve the air quality inside your home. You may not realize it, but air filters that are dirty and clogged are the primary reason for furnace malfunctions and damage.
