This Means Your Furnace is in Dire Need of Repair


When winter unleashes its chill, your furnace stands as your home’s steadfast defender, swiftly heating your living spaces and allowing for comfort even on the coldest days. Generally, furnaces are reliable, but sometimes issues arise, like when your furnace starts and stops before reaching the desired temperature. This issue, known as short cycling, signals a need for furnace service in Bellevue, WA.

Understanding Short Cycling & Furnace Repairs

Short cycling happens when your furnace initiates a heating cycle but shuts off prematurely, failing to complete its heating task. The cycle, typically starting with a signal from the thermostat to activate the heater, is cut short. Instead of running until the target temperature is reached, the furnace shuts down early, leaving your home inadequately heated.

Causes and Implications of Short Cycling

Combustion and Flame Sensors:

Furnaces operate on combustion principles, utilizing a pilot light ignited by an electronic system. A flame sensor ensures that the pilot light is functioning to avoid gas leaks. However, if the sensor becomes dirty or malfunctions, it may fail to detect the flame, causing the furnace to shut down to prevent gas hazards.

Thermostat Issues:

Malfunctioning or improperly placed thermostats can send incorrect signals to the furnace, leading to short cycling. Ensuring your thermostat is accurately calibrated and positioned away from drafts and direct heat sources is crucial for optimal furnace operation.

Overheating:

Your furnace might also short cycle due to overheating. This can happen when the heat exchanger gets too hot, triggering the safety switch to shut down the furnace. Overheating can be caused by restricted airflow due to dirty filters or blocked vents.

Improper Furnace Size:

If your furnace is too large for your home, it may heat quickly and then shut off, not running long enough to evenly distribute the heat. This can result in uneven heating and additional strain on the furnace components.

Frequent Wear and Tear:

Regular use can lead to wear and tear on furnace components, contributing to issues like short cycling. Regular maintenance can identify and rectify these problems early.

The Importance of Professional Furnace Repairs

Addressing short cycling quickly is crucial, as it can lead to bigger issues if ignored. Not only does it impact your home’s comfort, but it also strains your furnace, potentially leading to more significant repairs or even premature replacement.
