The manufacturer’s warranty coverage of a forced air furnace requires proof of annual professional maintenance. Otherwise, any repair costs are the responsibility of the homeowner. This is because manufacturers realize that the chance of a problem with operation increases without regular service. It’s recommended to schedule a tune-up for the furnace in the fall, prior to starting up the heater for the first time. A comprehensive inspection and adjustment makes sure all components are working at their best and ready for the upcoming workload. A licensed technician thoroughly troubleshoots and often uses performance sensors and software to identify any issues with operation. Resolving minor concerns promotes greater reliability and longevity from the system. The technician replaces any worn or broken parts, tightens electrical connections and lubricates moving parts. He verifies the integrity of the heat exchanger, pilot and thermostat. An intensive cleaning removes any buildup of contaminants, such as dust, dander, pollen, lint and mold that would otherwise restrict airflow. If the inner workings of the furnace are clogged with debris, the system needs to run longer and work harder to reach the thermostat setting. The heater will cost more to run and not last as long. It’s also a good idea to have the ductwork inspected and tested for leaks or a buildup of pollutants. Taking care of the furnace and ductwork provides for superior comfort and air quality throughout the winter. Lower utility bills, quieter sound levels and less impact on the environment are just some of the perks. Most maintenance plans include benefits such as priority scheduling, discounts on parts and labors and no added fees for overtime emergency services.
