I updated the natural gas gas furnace in my loft a little over multiple years ago. I was forced to buy a new oil furnace when the seasoned one hastily malfunctioned in the middle of a blizzard. The cause of the failure was an excessive buildup of dust and debris within the inner really workings. The accumulation of contaminants had clogged airflow, leading to longer running times and added wear and tear. The gas furnace ultimately overheated which caused a crack in the heat exchanger. Because a new heat exchanger costs as much as a whole new oil furnace, I opted for the upgrade of a new gas furnace. I spent extra for a higher AFUE rating, better safety features and extended manufacturer’s warranty. I also made sure to enroll in a service contract with the Heating, Ventilation, and A/C supplier that handled the upgrade. The service program includes annual cleaning and problem shooting of the gas furnace every year. This repair fulfills the obligations of the manufacturer’s warranty and ensures continued coverage. Plus, the service contract provides priority scheduling, discount on parts and labor, and no added charges for overtime service. I can call on the Heating, Ventilation, and A/C supplier at anytime, day or night or weekends, and get a licensed professional to the house within the hour. They guarantee their work, and offer flat rate pricing. The professional wears foot coverings to keep from tracking dirt through the house, and picks up any discarded parts or debris. Through the service plan, I also benefit from a discount when I eventually purchase a new gas furnace. The proactive annual repair keeps my heating unit operating at peak efficiency, capacity and reliability.
