How to know if your gas furnace is working properly

Your home’s heating and cooling system contribute a lot to your overall monthly utility expenses.

Therefore, you have to ensure your HVAC system operates in its best form.

For a gas furnace, you can check it periodically for signs of problems and fix them to restore it to its best performance. You can also have an HVAC professional analyze the HVAC equipment and produce a report for its performance. When checking the furnace to ensure it works well, it ensures it is quiet when operational, save for the occasional sounds a furnace produces when working. Check for unusual rumbles, squealing, and screeches as the furnace works. When you hear any of these sounds, your furnace is faulty. Call an HVAC repairman to troubleshoot and fix the HVAC equipment. A well-functioning gas furnace should also be odorless except for dirt smell and some burning dust in the first few cycles. Turn off your gas furnace if you smell unusual burning odors and reach out to your HVAC supplier. However, if you smell burning rubber, natural gas, or plastic, you should leave your home immediately and call 911. Check for wear and tear, rust, dirt deposits, or soot. Look at the color of the flame inside the furnace. If it is blue, your gas furnace is running as it should. But if the flame is yellow, your burner may be receiving insufficient oxygen and producing carbon monoxide. Check and clean air filters to ensure the heating system runs well. Identify your furnace’s specified temperature rise on a plate within the blower. Use an instant-read thermometer to check the temperature increase by positioning the thermometer inside a register near the blower component. The temperature rise needs to be close to the manufacturer’s specification. If it is not, you need to reach out to an HVAC technician for a professional solution.
