With autumn temperatures dropping in the Washington, D.C., and Northern Virginia area, many families are tempted to fire up their furnaces before the first chill. Before you turn the thermostat to a cozy 70 degrees, take a moment to inspect the system. As Patrick Garner, operations manager at Cardinal Plumbing Heating & Air Inc., explains, a simple pre‑season check can save homeowners from costly repairs later in the season.
Start with the filter
The most common culprit behind heating failures is a clogged air filter. “Make sure that thing is not clogged up,” Garner told WTOP. Modern thermostats and smart sensors often alert you when a filter is nearing the end of its life, but a visual check is quick and easy. Replacing a standard filter costs about $20 and takes roughly ten minutes – a small investment that can prevent a cascade of larger problems.
Watch for water buildup
When airflow is restricted, the furnace can freeze and then melt, filling the drip pan beneath the unit with water. If the pan overflows, homeowners may discover a sudden water leak in the attic or on the floor. “Customers will call and say, ‘I’m not getting any comfort here,’ or even worse, ‘Oh my God, there’s now a giant water leak from my attic down to my floor,’” Garner said. A clean filter restores proper airflow and eliminates this freeze‑thaw cycle.
Check vents and thermostat settings
Blocked vents in any room can also choke airflow. Walk through the house and ensure that furniture, curtains, or stored items are not covering supply or return grilles. Additionally, avoid the temptation to turn the thermostat off when you leave the house. “Find a comfortable setting, keep it there. Set a home‑and‑away schedule where the differential of that temperature is minor, because you’re not saving money. You’re actually making a system work a lot harder, and it’s not efficient,” Garner advised.
Plan for aging equipment
Even with diligent maintenance, heating systems age. Once a unit reaches ten to twelve years, it becomes wise to start budgeting for a replacement. “Once your system gets over 10, 12 years, that’s when you really do need to start considering setting aside a little bit of money for replacement,” Garner noted. Early planning can prevent the financial shock of an unexpected breakdown during the peak of winter.
Why early action matters for families
For families who rely on a warm home for comfort, health, and productivity, a functioning furnace is essential. A brief inspection now protects against the stress of emergency repairs, preserves the integrity of the home’s structure, and keeps utility bills predictable. Homeowners who take these steps can enjoy a worry‑free winter, confident that their heating system will perform when it matters most.
