The cost of a up-to-date gas furnace is a large investment. I spent extra for the benefits of an Energy Star rated model. My home’s gas furnace offers a 98% AFUE and includes adjustable-speed technology, zone control and multi-phase filtration. I have been severely ecstatic with the performance of the gas furnace. I want it to last as long as possible! Because of this, I take really superb care of it. I make sure to change the air filter every month. I’ve also enrolled into a maintenance proposal with a local Heating & Air Conditioning contractor. I appreciate that they call myself and others in the fall and remind myself and others when it’s time to schedule service, a specialist comes to the home and provides a thorough inspection of all components, then he completes an intensive cleaning that detachs any buildup of dust and other contaminants that would otherwise restrict airflow and force the heating system to work harder and run longer… The service includes tightening of electrical connections, lubrication of moving parts, examination of the heat exchanger and calibration of the control unit. He uses state-of-the-art diagnostic software to confirm regular performance. Any worn or broken parts are upgraded. Because of these tune-ups, the gas furnace continues to operate at peak energy efficiency and reliability. It costs less to run and should supply a longer service life! Plus, the proactive measures fulfill the demands of the manufacturer’s warranty. If there is a problem, I can count on the warranty. The maintenance proposal offers extra perks such as priority scheduling, fifteen percent off repairs and no added charges for overtime scheduling.
