Furnace Repair in Fort Collins

Signs Your Furnace Needs Professional Repair

You shouldn’t wait to schedule a furnace inspection if you notice any of the following problems:

• No heat or failure to start. A furnace that won’t start may have an ignition, thermostat, electrical, gas-supply, or safety-control problem that requires professional diagnosis.
• Weak airflow. Limited airflow from the vents can be associated with a dirty filter, blower problem, duct restriction, or another system issue.
• Cool air from vents. If the thermostat is set correctly but the furnace continues blowing cool air, the system may have an ignition, airflow, or heating-component problem.
• Unusual noises. Banging, whining, or rattling sounds coming from your furnace often indicate loose components, worn-out belts, or failing motors. Continuing to run the furnace may worsen the underlying problem.
• Inconsistent heating. If certain rooms remain chilly while others are too warm, your furnace may be struggling to distribute air properly. This points to potential issues with the ductwork, the thermostat, or a deteriorating blower motor.
• Frequent cycling. A furnace that turns on and off repeatedly without reaching your desired temperature is experiencing a condition known as short cycling. This strains your system and is frequently caused by a malfunctioning thermostat, internal overheating, or airflow restrictions.
• Ignition or pilot-light problems. Repeated clicking, delayed ignition, or a pilot light that won’t remain lit can indicate a problem with the ignition system, flame sensor, fuel supply, or safety controls.
• Repeated shutdowns. A furnace that starts and then shuts down before completing a heating cycle may be overheating or responding to a control or airflow problem. Don’t bypass safety controls to keep it running.
• Unusual odors or smoke. Persistent burning smells, visible smoke, or a gas odor require immediate attention and shouldn’t be treated as routine troubleshooting. Stop operating the equipment and seek emergency assistance from a safe location when fire or gas is suspected.
• Yellow burner flame. A healthy gas furnace flame should burn bright blue. A yellow or flickering flame suggests poor combustion and a potential carbon monoxide risk. Treat this as urgent: Turn off your furnace, open doors and windows to ventilate your property, and call us to investigate. If your carbon monoxide detector goes off, evacuate your property and call 9-1-1. 
• Rising energy bills. An unexpected and sustained increase in your monthly heating costs means your system is likely working harder than necessary to produce heat. We can diagnose the source of heating inefficiency and discuss repair options.

Frequently Asked Questions

How Long Do Furnace Repairs Usually Take?

The duration of a furnace repair depends on the nature and complexity of the underlying malfunction. Our team can generally resolve many common heating issues, such as replacing a faulty ignitor, swapping out a worn capacitor, or cleaning a dirty flame sensor, in 1 to 2 hours during the initial visit. More extensive jobs, like replacing a primary blower motor, fixing a cracked heat exchanger, or addressing intricate electrical faults, may require several hours or a half-day of work. Equipment condition, access, required safety checks, and parts availability can also affect the timeline, particularly if a component must be ordered from the manufacturer. 

We arrive in stocked service vehicles, allowing us to complete many repairs in a single visit. 

How Much Will a Furnace Repair Cost?

Repair costs vary depending on the component that has failed and the complexity of the fix. Swapping out a sensor or capacitor tends to be less expensive than replacing a cracked heat exchanger or primary blower motor. We provide a clear, upfront estimate after our diagnostic inspection and before repair work begins.

Why Is My Furnace Blowing Cold Air?

The thermostat fan may be set to “on” rather than “auto,” causing the blower to run continuously even when the heating cycle is off. Other possible causes include a dirty flame sensor, an extinguished pilot light, or a clogged air filter. You can confirm the thermostat setting and check whether the filter is visibly clogged, but don’t attempt to bypass furnace safety controls. We can identify the mechanical or electrical fault and explain your repair options.
