When I first started up my gas gas furnace in early October, it acted strange. The oil furnace made a tremendous amount of noise, and a lot of dust blew from the vents. I assumed this was caused by resting idle throughout the Spring, summer time and early fall. I hoped that after running for a few nights, the system would work out the troubles. Unfortunately, this past Winter time was one of the coldest on record. The temperature plummeted to fifteen below zero, with a vicious wind chill and tremendous amount of snowfall. The gas furnace carried an unusually heavy workload and seemed to run constantly, I kept turning the temperature control higher and higher, and yet my condo felt slightly chilly. There were chilly spots and drafts in certain rooms. I absolutely should have called an Heating, Ventilation, and A/C company for repair. Although I made sure to change the air filter every few weeks, I simply never found the time to schedule professional service. The horrible weather created a tremendous amount of work. I spent a lot of hours shoveling the driveway, brushing snow off my car, knocking icicles off the roof and scraping ice. I distraught that the back deck would collapse from the weight of the snow. I should have paid closer attention to the deteriorating performance of the gas furnace. My oil furnace quit while all of us were in the middle of the night, over the weekend, when the temperature had dipped to twenty-3 below zero. There was simply no way to survive without heat until proper company hours on Thursday. I had no choice however to pay extra for emergency service. The Heating, Ventilation, and A/C company confirmed that the malfunction was caused by the buildup of dust and contaminants within the inner finally workings. He said that if I would have called when I first started up the gas furnace, a simple cleaning would have fixed the issue. Instead, I got stuck paying to replace many parts.
