I substituted the natural gas oil furnace in my apartment a little over numerous years ago. I was forced to buy a current heating plan when the old 1 suddenly malfunctioned in the middle of a blizzard. The cause of the failure was an excessive buildup of dust in addition to debris within the inner workings. The accumulation of contaminants had blocked airflow, leading to longer running times in addition to added wear in addition to tear. The oil furnace ultimately hot which caused a crack in the heat exchanger. Because a current heat exchanger costs as much as a whole current gas furnace, I opted for the installation of a new oil furnace. I spent extra for a higher AFUE rating, better safety features in addition to extended manufacturer’s warranty. I also made sure to enroll in a maintenance contract with the Heating, Ventilation & A/C contractor that handled the installation. The maintenance program includes annual cleaning in addition to problem shooting of the oil furnace every year. This maintenance fulfills the obligations of the manufacturer’s warranty in addition to ensures continued coverage. Plus, the maintenance contract provides priority scheduling, discount on parts in addition to labor, in addition to no added charges for overtime service. I can call on the Heating, Ventilation & A/C contractor at anytime, afternoon or night or weekends, in addition to get a licensed professional to the home within the hour. They guarantee their work, in addition to offer flat rate pricing. The professional wears foot coverings to keep from tracking dirt through the house, in addition to picks up any discarded parts or debris. Through the maintenance plan, I also benefit from a discount when I eventually purchase a current oil furnace. The proactive annual maintenance keeps my heating equipment operating at peak efficiency, capacity in addition to reliability.
