What is the most expensive repair on a furnace?

One of the most expensive furnace repairs is replacing a cracked heat exchanger. This issue is common in older heating systems and can pose a safety risk due to potential carbon monoxide leaks. Many homeowners compare the cost of repair versus replacement to determine the best long-term solution.

What is the most common furnace failure?

The most common furnace failure is a faulty ignitor. When the ignitor stops working, the furnace can’t start properly, leading to problems like no heat, short cycling, or blowing cool air. Symptoms are often noticeable during winter, prompting homeowners to seek repair services.

What is the average cost to repair a furnace?

The average cost to repair a furnace typically ranges from $150 to $900, depending on the part needing attention. Minor repairs include thermostat adjustments or filter replacements, while major repairs like blower motors or ignition components can be more expensive. Emergency service during peak winter months may also increase costs.

Are furnace repairs covered by homeowners insurance?

Homeowners insurance usually does not cover furnace repairs caused by age, wear, or maintenance issues. Coverage may apply if the furnace is damaged by a sudden, unexpected event such as fire, severe weather, or water damage. Routine breakdowns and mechanical failures are generally not covered.

What is the life expectancy of a furnace?

Most furnaces last 15 to 20 years depending on the model, installation quality, and maintenance. Furnaces receiving regular tune-ups, filter changes, and timely repairs run more efficiently and remain in good condition longer than neglected systems.

Why Furnaces Short Cycle and What It Means for Your Home

Furnace short cycling is a common problem that can reduce efficiency, increase energy bills, and strain your heating system. Homeowners often ask, how do I fix my furnace from short cycling? Short cycling occurs when your furnace turns on and off rapidly without completing a full heating cycle. This can be caused by dirty air filters, clogged vents, thermostat issues, or a malfunctioning blower motor. Understanding these causes is the first step in preventing further damage and ensuring consistent heat throughout your home.

Common Causes of Furnace Short Cycling

Dirty or clogged air filters: Restricted airflow forces your furnace to work harder and shut down prematurely.
Thermostat problems: Malfunctioning or incorrectly placed thermostats can trigger frequent on/off cycles.
Overheating components: A dirty blower or blocked ducts can overheat the furnace and cause it to shut down for safety.
Improperly sized furnace: A unit that’s too large for your home may heat too quickly, cycling off before reaching optimal efficiency.

How Do I Fix My Furnace From Short Cycling?

To fix furnace short cycling, start by performing basic maintenance:

Replace or clean air filters regularly.
Inspect and clean vents and ductwork.
Check the thermostat and consider upgrading to a programmable or smart thermostat.
Ensure the furnace is correctly sized for your home.

For persistent problems, professional furnace repair services are recommended. Coastal Heating and Cooling technicians can diagnose and repair issues with the blower motor, thermostat, or control board to restore your furnace to safe and efficient operation.
