Sterling, Va. – September 18, 2026 -- Cardinal Plumbing Heating & Air is urging Northern Virginia homeowners to complete a short list of fall maintenance tasks before freezing temperatures arrive, warning that delays can lead to costly winter emergencies like burst pipes and heating failures.
"Fall is the ideal window because homeowners still have time to act before freezing weather puts stress on pipes, outdoor faucets and heating equipment," said Daniel Fuentes, co-founder of Cardinal Plumbing Heating & Air. He noted that a single cold snap in the region can quickly expose weak spots in home systems.
Disconnecting hoses and draining spigots prevents burst indoor pipes
Fuentes recommends homeowners disconnect garden hoses and drain exterior spigots immediately, since leaving a hose attached traps water inside the faucet and can lead to a burst pipe indoors.
Clogged HVAC filters can cause furnaces to overheat
Replacing HVAC air filters is advised to maintain airflow, as clogged filters both increase energy consumption and risk overheating furnaces. Homeowners should also clear leaves and debris from outdoor HVAC units, maintaining a minimum two-foot clearance around the equipment.
Foam insulation tubes protect pipes in unheated spaces
Exposed pipes in basements, crawlspaces, attics and garages should be wrapped with foam pipe insulation tubes to prevent freezing and bursting in unheated areas of the home.
Professional inspections catch carbon monoxide and safety issues
Cardinal Plumbing Heating & Air recommends scheduling a licensed HVAC technician for a seasonal furnace inspection, covering safety controls, electrical components, moving parts and carbon monoxide-related concerns.
"Once freezing weather arrives, service calls often increase as homeowners discover no-heat issues, frozen outdoor lines or equipment that has not been maintained since the previous winter," Fuentes said.
Throughout September, the company is offering $49 heating system tune-ups that include a carbon monoxide safety check for Northern Virginia homeowners.
