Eleven months of work, most of them cold
Your furnace carries this house from October through May. On the nights that drop to 16°F, it cycles on and off for hours, and every start puts a load on the igniter and the ignition control board. When one of those parts wears out, the furnace stops mid-cycle and the house goes cold fast at that temperature.
Summer asks less of the system but the heat is real, afternoons averaging 86°F. The air conditioner runs harder to hold the house at temperature, and a low refrigerant charge or a failing capacitor shows up as warm air blowing when it should be cold. Weld County also sees its share of wind, 172 damaging wind events over the last ten years, and an outdoor unit takes that weather straight on. Add in the power outages that hit Colorado households, and a furnace or air conditioner that will not restart on its own after the lights come back is worth checking.

A new furnace and air conditioner would cut about $120 a year off heating and cooling for a typical Weld County home.
Estimates for a typical Weld County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Colorado fuel prices and NOAA climate normals. Your home will differ.
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. Make sure it's set to heat and the setpoint is above room temperature, since a setting bumped a degree or two can look like a dead system. Check your breaker panel next, since a tripped breaker will kill a furnace or heat pump without any other warning. If the furnace has a standing pilot, look for the flame. If it uses an igniter instead, you won't see a flame until it's actually firing, and a bad igniter is one of the most common reasons a furnace won't start. At 16°F on a winter night here, a furnace that won't fire needs attention fast, so if the basics check out, it's time to call for repair.
- Why is my system running but not cooling the house?
- Check the air filter first. A clogged filter chokes off airflow, and the coil can freeze up behind it, which stops cold air from reaching your vents even though the blower keeps running. Look at the outdoor unit too. If the fan isn't spinning or the coil is caked with debris, the system can't get rid of heat properly. Set the thermostat fan to auto rather than on, since running the fan constantly can push warm air through before the coil has cooled it. If the filter is clean and the outdoor unit looks fine but the house still isn't cooling on an 86°F afternoon, the system likely needs a contractor to check refrigerant levels or the compressor.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings first, since a dead battery or a setting left on the wrong mode causes more no-heat and no-cool calls than people expect. Check the breaker panel and any switch near the furnace or air handler, since a flipped switch looks exactly like a dead unit. Replace the air filter if it's dirty, since restricted airflow causes problems on both the heating and cooling side. If the outdoor unit is covered in snow, ice, or leaves, clear it, since Greeley sees enough wind and winter storms that debris around the unit is a real possibility. If none of that fixes it, a contractor will need to diagnose the rest.
