Ten months of heat a year in Thermopolis

Your furnace works September through June here. Winter nights average 12°F, so on the coldest nights it's cycling on and off most of the day to keep up. That kind of run time wears on the igniter and the flame sensor first, and when one of them fails, the burner won't light and the house goes cold.

July and August bring afternoons near 80°F, so your air conditioner gets a shorter season but still needs to be ready. Wyoming sees its share of winter storms and wind, and power interruptions that follow can be hard on a system that was already due for a repair. If your thermostat won't hold a setting or one room won't heat or cool like the rest, that's the kind of problem that shows up first in a house that leans on its system as many months as this one does.

A new furnace and air conditioner would cut about $150 a year off heating and cooling for a typical Hot Springs County home.

  • A new furnace and AC$720 a year
  • An older furnace and AC$870 a year

Estimates for a typical Hot Springs County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Wyoming 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 is set to heat and the temperature is set above the room temperature, then check that the furnace switch and breaker are both on. If the furnace runs a standing pilot, look for the pilot light itself. If it uses electronic ignition and you hear clicking but no flame, the igniter or flame sensor may be the problem, and that is a job for a contractor. With winter nights here averaging 12°F, a furnace that short cycles or will not stay lit needs attention quickly.
Why is my system running but not cooling the house?
Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the system can end up blowing air that is barely cooler than the room. Also check that nothing is blocking the outdoor unit, since it needs open airflow around it to release heat. If the filter is clean and the outdoor unit is clear but the house still is not cooling, the refrigerant charge or the compressor may be the issue, and a contractor will need to check it with gauges.
What can I check before calling for HVAC repair?
Check the thermostat settings, the batteries in it if it has any, and the breaker or switch for the system. Check the air filter and replace it if it is dirty, since a clogged filter can cause problems that look like bigger issues. Look at the outdoor unit if you have one and clear away any leaves, snow, or debris around it. If the system still is not working after that, a contractor can diagnose what is actually wrong.
