The moment I started up the furnace in late fall, I knew there was a problem, then a strong odor of burning lint as well as an excessive amount of dust poured from the vents. Although the system provided heat, there was truly less air, plus it was making some truly weird sounds. I tried changing the air filter plus vacuuming out the vents, however my efforts made no difference. I figured it best to call for service instantly. I didn’t want to risk causing further disfigurement by operating a malfunctioning system. Because our local winters tend to last for more than half the year plus frequently bring temperatures well below chilly, the furnace is essential, and going without heat isn’t an option, plus our weekly energy costs are consistently a concern. The furnace needs to operate at peak efficiency, capacity plus reliability. At that time of year, all of the local Heating, Ventilation, plus A/C companies were severely busy. I needed to wait over a week for a professional to come to the house, but during that time, I refused to run the furnace, plus the dwelling was especially cold plus uncomfortable. When the professional checked the furnace, he said that holding off starting it up had been the right decision. The buildup of dust plus other debris within the inner workings was blocking airflow. The added wear plus tear could have truly caused the furnace to overheat plus potentially caused large problems… Fortunately, all that was required was a thorough cleaning plus tightening of a few wires. The furnace ran perfectly throughout the winter.
