Local considerations

Cold winters at altitude put furnaces under long run cycles, and combustion air supply matters more at elevation. In Golden that determines whether heating calls here are combustion problems or refrigerant-cycle problems, and those need different parts on the truck.

Zone thermostats in Golden multi-zone systems can fail independently without stopping the boiler or furnace. A zone that reads the setpoint but never opens its valve is a thermostat or valve problem, not an equipment problem.

Rising fuel bills combined with longer run times are the quiet signal that a furnace is losing efficiency and the replacement clock is running.

Auxiliary heat covers the shortfall when outdoor temperatures drop far enough that the heat pump cannot keep up alone, which is by design, not a failure.

Details

What is your thermostat reading?

Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

Degrees F

Indoor temperature

Likely cause band: Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
Urgency: Call today
Read next: AC not cooling

Thermostat reading against likely cause. JavaScript is off, so the dial is shown as a table.
Reading	Likely cause	Urgency
60 F	The heating side is not producing heat at all. Ignition lockout, a dirty flame sensor or a tripped limit switch.	Call now
62 F	The burner is lighting then dropping out, or the blower is running without heat behind it.	Call now
64 F	A heat pump that is not completing the switch into heating mode, or one stuck relying on auxiliary resistance heat.	Call now
66 F	Heat is being produced but not distributed. Airflow restriction, duct losses or a zoning fault.	Call today
68 F	Close to a normal winter setpoint. If the room feels colder than this reading, suspect the thermostat itself.	Call today
70 F	Within the normal comfort band. Nothing here points at a fault on its own.	Monitor
72 F	Within the normal comfort band. Worth noting how long the system runs to hold this figure.	Monitor
74 F	Slightly above a typical cooling setpoint. If the system cycles on and off rapidly, that is the fault to chase.	Monitor
76 F	The system is falling behind setpoint. Airflow restriction or a coil that cannot absorb heat.	Call today
78 F	Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.	Call today
80 F	Supply air is close to room temperature. The refrigerant side or the compressor is not contributing.	Call today
82 F	Well above setpoint with the system running. Check for ice on the indoor coil or the line set.	Call now
84 F	Substantial capacity loss. A leak that has been developing across the season is the usual finding.	Call now
86 F	The system is effectively not cooling. Check whether the outdoor unit is running at all or tripping its breaker.	Call now
88 F	Indoor temperature is approaching outdoor temperature, which means no useful cooling is happening.	Call now
90 F	A health risk in a heat event. Move anyone vulnerable to a cooler space and treat this as urgent.	Call now

What to do while you wait

Set the system to off instead of raising the setpoint, which will not force it to run.
Check whether the outdoor unit on a heat pump is iced over, and do not chip at it.
Look at the filter and replace it if light will not pass through.
Never heat a room with a gas range or an outdoor appliance. That is a carbon monoxide risk.

Questions

Golden HVAC questions

What if my furnace is still under warranty?

Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.

My furnace locks out after three tries. What is that?

Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.

Is a cracked heat exchanger repairable?

No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.

Can I run a space heater meanwhile?

Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.

Do I need a carbon monoxide alarm?

If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
