Furnace Repair: How to Troubleshoot Common Heating Malfunctions

A furnace uses numerous components to provide consistent warmth throughout your home. Repairs on forced-air or gas designs can be expected to occur every so often and increase with improper care. Whereas an electrical design can sit idly until repairs can be performed, gas heaters are more time-critical in many circumstances. Your forced-air system can suffer a range of problems requiring the assistance of professional technicians. A gas leak, for instance, requires an immediate exit of the structure along with turning off the supply valve. Many additional complications could arise with your gas unit, including the pilot light going out, insufficient heating, blowing of cold air, igniting problems, and inconsistent cycling. Periodic maintenance can decrease the need for furnace repair. Having a professional perform a regular checkup on the system once or twice a year ensures proper component operation and provides improved efficiency.

Atlanta Heating: Where You Begin Depends on the Problem

Atlanta heating professionals inspect and clean all major components of your forced-air system including the flue, controls, burners, valves, belts, pulleys, filter, motor, and the return air duct. Certain components require adjustment and lubrication for optimal performance. A slipped belt or particle buildup on components affects the ability of an HVAC to operate. This, in turn, causes various parts to take on increased workloads to provide the same operational efficiency. You will experience higher energy costs, more frequent repairs, and inconsistent operation when maintenance is not performed as recommended. The pilot light could go out because of a faulty thermocouple, a clogged opening, or due to improper flame settings. Clogging can be remedied by using a wire to push through the buildup. This should not be performed unless the gas supply and power have been turned off. When your furnace is not supplying sufficient heating, you should verify the airflow is not being blocked and thermostat settings are correct. Acquire the help of an Atlanta heating professional when these small steps do not alleviate the problem.

In some situations, your furnace might stop providing heat altogether, causing an uncomfortable environment. Thermostat malfunctions are the most common reason for an HVAC malfunction, with blown fuses or breakers coming in as second. Gas furnaces have the additional possibility of the pilot light being out. Turn off the main power to the system, then check to see if any of these items are causing the issue. Resetting the system is another option in cases where the motor has been overloaded. A furnace might cycle too frequently or fail to kick on when necessary, making it difficult to receive a consistent, comfortable temperature. This can be caused by a faulty thermostat, clogged filter, or blower malfunctions. Broken belts often contribute to a negative air discharge during operation.

Multiple problems are possible regardless of whether or not your heater is gas fueled or electrical. Begin by evaluating the above items and then call a qualified Bardi professional for further inspection of the problem. In some cases, a furnace repair might be unavoidable, and would be better handled by an experienced professional.
