Your furnace will only operate at its fullest potential for years to come if you take care of it now. Here are five ways to improve the furnace lifespan and decrease the money you spend to operate it this season and for years to come.
- Change the filter. Replacing the filter is easy and inexpensive. A clean filter ensures that air moves effortlessly through the system. This increases the furnace lifespan because air can be moved without the furnace working harder than necessary. Plus, this conserves fuel and saves you money.

- Tune up your furnace annually. Preventive service at the start of the heating season improves the furnace lifespan, setting up the unit for an efficient, problem-free winter. It’s a great way to catch problems that are just beginning to form and put a stop to them before they get worse.
- Seal leaky ductwork. Forced air systems lose much of their energy through leaky ducts. A licensed technician can get into hard-to-reach places and check for joints and seams that have leaks. These gaps can then be sealed with duct mastic, a heat-resistant material that seals the gaps indefinitely.
- Clean your ductwork professionally. This should be done every three to five years to prevent dust and allergens from being blown into the living space. Vacuum supply and return registers periodically to keep them free from dirt between professional cleanings.
- Keep registers clear of obstructions. Both warm air supply and cold air return vents should be clear of furniture, rugs, curtains and other obstructions. By keeping the vents clear, you promote good air circulation around the home, which results in greater comfort for every occupant and improved system efficiency.
