No two heating systems break the same way, and in Colorado Springs homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often stall on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve leaves the system stuck in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
Most of our service calls are for Furnace Repair. Start there if your system isn't running right.
Warning Signs for Heating Repair
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- The system starting and stopping every few minutes without warming the house
- Banging at startup caused by burners lighting late
- Higher heating bills with less comfort to show for them
- A rotten-egg, burning, or musty smell once the heat kicks on
- A furnace that tries to light, clicks, and then quits
- Cold air, or no air at all, when the thermostat calls for heat
- A heat pump's outdoor unit encased in frost or ice
- Cold rooms in one part of the house while others are comfortable
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (719) 697-8646 for a prompt inspection.
