It took myself and others way too long to fully care about the importance of annual oil furnace service! I dealt with minor problems with the heating plan that were caused by a lack of annual upkeep! While the problems were small and particularly resolved, I still ended up paying a hefty service bill, but plus, any oil furnace malfunction is disruptive, however higher energy bills, diminished comfort and degraded air quality were a few of the consequences. I’d also need to interrupt our bi-weekly routine to meet an Heating and Air Conditioning contractor. I sometimes was forced to take off from work to get the service accomplished. It’s much cheaper and easier to simply schedule proactive service at a convenient time while in the fall season. I have the oil furnace checked and adjusted prior to the heating system. I can then be sure that every component is in tip top shape and working at its best, and the Heating and Air Conditioning contractor provides a thorough cleaning of the inner workings, removing any buildup of dust, dirt and grime. She tightens electrical connections, lubricates moving parts and verifies the integrity of the heat exchanger. She checks the air filter, the control unit and the burner assembly of the oil furnace. I think the heating plan is operating at maximum capacity, efficiency and safety levels. I prefer superior temperature control and air quality while paying less every week. Plus, these services fulfill the requirements of the manufacturer’s warranty. If something should go wrong, the replacement parts are covered. I enrolled in a service plan that includes priority scheduling, no extra fees for overtime services and a discount on repairs.
