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