How To Troubleshoot When Your Room Heating Is Not Working

January 23, 2023

Faults with an HVAC system can range from simple to complex. Before seeking professional heating repair in Alpharetta, GA, try some DIY troubleshooting solutions. A self-inspection of your HVAC system can help you identify and fix certain issues without incurring technician costs.


Ignoring HVAC repairs and continuing to use a malfunctioning heating unit can lead to poor indoor air quality, uncomfortable temperatures, disturbing noises, allergies, and headaches. Common causes of HVAC problems include dirty filters, blocked air vents, obstructions near air registers, incorrect thermostat settings, blown fuses, insufficient fuel, or a broken heat exchanger.


Troubleshooting Your Heating System



Get a New Air Filter


How often you replace your air filter depends on your environment. Homes with pets or in polluted areas should replace filters every 30 days, while smaller families without pets can wait 60-90 days. Dirty filters can cause heating issues and unhealthy indoor air. Ensure timely replacement to avoid problems. For professional heating services in Lawrenceville, GA, and nearby areas, hire reliable experts.


Adjust the Thermostat


Forgetting to adjust the thermostat for seasonal changes can impact your system’s performance. Consider installing a programmable or smart thermostat for convenience. If your thermostat is malfunctioning, recalibration or professional help may be needed.


Remove Obstructions


Furniture or objects blocking air vents can disrupt airflow and heating efficiency. Ensure vents and exhausts are clear to allow proper air circulation.


Open the Gas Valve


If the gas valve was turned off during cleaning or maintenance, ensure it’s open. The lever should be parallel to the gas pipe. If gas is still not supplied, schedule a heating repair or consider heater replacement in Lawrenceville, GA.


Fix the Circuit Breaker


While furnaces generate heat by burning fuel, components like blower fans and thermostats require electricity. Check the circuit breaker for issues and restart it if necessary.


Schedule an Inspection


Regular maintenance prevents wear and tear. If you haven’t scheduled a seasonal tune-up recently, book one immediately to avoid system malfunctions.
