A furnace blowing cold air usually points to a pilot light or ignition issue, a dirty flame sensor, an overheating heat exchanger that tripped a safety limit switch, or a thermostat set to "fan only." Try checking your thermostat setting first—if it's set to "auto" and still blowing cold, call us for a professional diagnosis.
We recommend annual furnace maintenance, ideally in early fall before the heating season kicks in. Washington's damp climate means furnaces work hard from October through March. A yearly tune-up catches small issues early, keeps your system running efficiently, and helps avoid mid-winter breakdowns when you need heat most.
A complete furnace tune-up includes: inspecting and cleaning the burners and heat exchanger, testing the ignition system and flame sensor, checking gas pressure and connections, inspecting the vent system for blockages, testing safety controls and limit switches, replacing or cleaning the air filter, checking thermostat calibration, and measuring system efficiency. We provide a detailed report after every service.
This is called short cycling, and common causes include: a clogged air filter restricting airflow, an oversized furnace that heats too quickly, a malfunctioning thermostat, or a dirty flame sensor that can't detect the flame consistently. Short cycling wastes energy and wears out components faster. Call us for a proper diagnosis—it's often a quick fix.
A burning smell when you first turn on the furnace for the season is usually just dust burning off the heat exchanger—it should go away within a few hours. However, if the smell persists, smells like gas or burning plastic, or you see smoke, shut the furnace off immediately and call us. These could indicate a gas leak, electrical issue, or blocked vent.
Typically, standard homeowners insurance does not cover furnace repairs from normal wear and tear. It may cover damage from a covered peril like a fire, storm, or water damage that affects your furnace. We recommend checking your specific policy. For maintenance-related repairs, we offer upfront pricing and financing options to help manage costs.
Absolutely—a dirty air filter is one of the most common causes of furnace issues. It restricts airflow, which can cause the heat exchanger to overheat and trigger the safety limit switch, leading to short cycling or complete shutdown. It also makes your blower motor work harder, reducing efficiency and potentially shortening your furnace's lifespan. We recommend checking your filter monthly during heating season.
