Eleven months of work a year, most of it in the cold
Your furnace carries this house from October through May, eight months of the year. On winter nights averaging 19°F, it cycles on and off for hours at a stretch, and every start puts wear on the igniter and the burner. Most furnaces need electricity to fire the burner, so when the power goes out, the heat stops with it. Colorado saw 13 percent of households lose power for a full day or more in 2024, and the ten years of records here include 184 winter storms.
Summer is shorter, just June through August, but afternoons averaging 88°F still push the air conditioner hard for those three months. The same records show 209 damaging wind events over that span, hard on an outdoor unit and the wiring that feeds it. Between the two seasons, this system runs nearly all year with barely a month of rest.

A new furnace and air conditioner would cut about $110 a year off heating and cooling for a typical Pueblo County home.

Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is set above the room temperature, and make sure it has power if it runs on batteries. If the thermostat looks fine, check the breaker for the furnace and the furnace's own switch, which looks like a light switch near the unit. Gas furnaces also need a pilot or an igniter to light, and if that part has failed the furnace will run air but never get warm. At 19°F on a winter night here, a furnace that will not fire needs a contractor out the same day.
- Why is my system running but not cooling the house?
- The air is moving but something is stopping the heat from leaving the house. A dirty filter is the most common cause, since it blocks airflow across the coil and can freeze it. Check the outdoor unit too. If the coil or fan outside is caked with dirt or leaves, the system cannot get rid of the heat it pulls from inside. If the filter is clean and the outdoor unit is clear, the system likely needs a contractor to check the refrigerant charge.
- What can I check before calling for HVAC repair?
- Check the thermostat first, its setting, its mode, and its batteries if it has any. Then check the breaker panel for a tripped breaker, and look at the furnace or air handler for a power switch that may have been bumped off. Pull the filter and hold it up to a light. If you cannot see light through it, that alone can cause both heating and cooling problems. Telling the contractor what you found saves time on the visit.
