Call (858) 293-9400A furnace problem can begin with a small change in sound, airflow, or heat. Turn the system off if you smell gas, and contact the gas utility or emergency services from outside the building.
The thermostat may not be calling for heat, or the furnace may have a power, ignition, fuel, or safety-control issue. A technician can test the system and identify the failed component.
Try this firstCheck that the thermostat is set to heat and the furnace breaker is on.
Call about thisAir may move through the ducts while the burners or heating elements do not operate. A dirty filter, ignition problem, or limit switch issue can contribute.
Try this firstReplace a dirty filter if you have the correct size and type.
Call about thisShort cycling means the furnace starts and stops before completing a normal heating cycle. Restricted airflow, thermostat placement, or a safety-control problem may be involved.
Try this firstMake sure supply vents and return grilles are open and unobstructed.
Call about thisBanging, rattling, squealing, or scraping can point to loose panels, blower parts, or other mechanical issues. New or persistent noises warrant an inspection.
Try this firstCheck that the furnace access panel is fully closed.
Call about thisLow airflow can leave rooms unevenly heated and make the furnace work harder. A clogged filter, blocked return, or blower problem may be the cause.
Try this firstRemove furniture, boxes, and rugs from return-air grilles.
Call about thisA furnace that repeatedly shuts down or needs resetting may be responding to a fault or safety condition. Repeated resets can mask the underlying problem.
Try this firstNote any flashing status-light pattern without opening sealed components.
Call about thisHomes along the Front Range experience changing winter weather and large differences in elevation, which can affect heating demand.
Eastern Colorado includes communities spread across open plains where winter heating is important for occupied homes and buildings.
Southern Colorado includes high-elevation mountain communities, valleys, and Front Range cities with varied winter conditions.
Mountain and western communities have widely varying elevations and winter weather, making dependable indoor heat a practical concern.
| Part | What it does | Signs it is failing |
|---|---|---|
| Thermostat | Signals the furnace to start and stop heating. | The temperature setting does not match system operation, or the furnace does not respond. |
| Air filter | Captures airborne particles before air enters the furnace. | Reduced airflow, excess dust, or a visibly loaded filter. |
| Igniter | Starts combustion in many gas furnaces. | The furnace attempts to start but does not produce heat. |
| Blower motor | Moves heated air through the duct system. | Weak airflow, unusual motor noise, or no air from vents. |
| Limit switch | Monitors furnace temperature and helps prevent overheating. | Short cycling or shutdowns associated with restricted airflow or overheating. |
Furnace configurations differ by fuel type, age, and manufacturer, so diagnosis starts with the equipment at the property.

Call Furnace Repair Colorado and describe the furnace problem, your location, and any symptoms you have noticed. A dispatcher can discuss service availability for your area.
Check the thermostat setting, furnace breaker, and air filter. If the system still will not start, arrange a diagnosis rather than repeatedly resetting it.
Cold air can result from a thermostat setting, ignition problem, fuel issue, airflow restriction, or safety shutdown. A technician can identify the cause after inspecting the equipment.
New banging, squealing, scraping, or repeated clicking should be checked. Turn the furnace off if you smell gas, smell burning, or suspect an unsafe condition.
Have your address, furnace fuel type if known, the symptoms, thermostat setting, and any error-light pattern ready.
Tell us your town and what is happening.
