The technician will inspect the furnace for signs of dust, debris, wear and tear of moving parts, heck the heat exchanger for rust and cracks, inspect the burners, and tighten the wires. The technician will check the furnace for minor issues and fix them before they develop into major ones. As debris and dirt can cause friction and damage vital components of the furnace, the technician will clean these parts. They will also lubricate the motor to ensure less friction and longer life for the motor.
You can also ask the technician who comes to check the furnace to inspect the ductwork. This will help spot leaks from cracks, holes, and gaps in the duct work. A properly sealed and insulated ductwork will deliver the heat to where it is required and reduce energy consumption. If heat is lost from the duct work, the unit will have to work more, consuming more energy and undergoing more wear and tear.
Changing Air Filters
While an annual inspection of the furnace by profession technicians will get it ready for the cooler months of the year, you need to change the filers at least once a month. A dirty filer can clog the airways and make the unit work harder. Apart from the greater energy consumption, blocked filers can also lead to uneven heating of rooms. Depending on the type of filter you are using, you need to either change them or wash them before reusing them.
Program the Thermostat
At the beginning of the heating season, program the thermostat to keep the home warm when you are in and cooler when you are away. This will help reduce energy bills without reducing your comfort.
Keep Vents Clear
Another way of ensuring optimal use of the furnace or heating unit is to ensure that the vents are not blocked by drapes, furniture, or other obstacles. Check all vents to ensure that free flow of air is possible.
Scheduling a furnace inspection before the heating season begins can help ensure that you stay warm throughout the fall and winter months without having to worry about unusually high energy bills or sudden breakdown of the heating system.
