Neglecting furnace maintenance

After investing a considerable amount of money into a high-efficiency, state-of-the-art furnace, I assumed I could take my winter comfort for granted.

Other than changing the air filter every once in a while, I totally neglected the heating system. Within a couple of years, I noticed the performance of the furnace had diminished considerably. I figured there was some defect in the unit. Although I’d chosen a well-known manufacturer, I was worried that the furnace was inferior quality. I called a local HVAC contractor to take a look at the heater. When he accessed the inner workings, he found a significant buildup of contaminants. He asked how long it had been since I’d had the furnace serviced. After I admitted that I’d never scheduled professional maintenance, he explained that dust and other debris can wreak havoc with furnace operation. As pollutants accumulate on the various components, they restrict airflow through the system. The furnace then needs to run longer and work harder to achieve the thermostat setting. Plus, the dander, bacteria, mold spores and harmful toxins can get spread into the breathing air and cause concerns with indoor air quality. He explained that moving parts of the motor require lubrication, wires need to be tested and it’s super important to inspect the integrity of the heat exchanger. Once he completed a thorough cleaning, adjustment and tuning of the furnace, it was back to running like brand new. The technician convinced me to enroll in a maintenance plan that includes service for the heating system every fall. I need proof of this service to fulfill the stipulations of the manufacturer’s warranty coverage.
