Ten months of work a year on your system
Cortez asks for heat from October through May and needs cooling in July and August. That is ten months of the year your system is running. Winter nights average 19°F, so the furnace cycles on and off for hours to hold the house steady, and every start puts wear on the igniter and the ignition control board. Summer afternoons average 84°F, which is not extreme, but the AC still has to answer for it after eight months of heating wear on the same blower and electrical parts.
Montezuma County has seen 115 winter storms and 22 damaging wind events over the past ten years. Storms like that knock out power, and 13% of Colorado households lost power for 24 hours or more in 2024. A furnace or AC that will not start after an outage is often just waiting on a reset, but if it stays dead, the problem is usually in the parts that took the wear before the power went out.

A new furnace and air conditioner would cut about $110 a year off heating and cooling for a typical Montezuma County home.
Estimates for a typical Montezuma 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 temperature is set above the room's current reading, and check that it has power if it runs on batteries. If the thermostat looks fine, check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts it off too. Gas furnaces also need a pilot light or igniter to fire, so if you hear the blower running but feel no heat, that's worth telling the contractor when they come out. With winter nights here dropping to 19°F on average, a furnace that won't hold heat needs attention fast.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter blocking airflow across the coil. Check it first and replace it if it's gray or clogged. If the filter is clean and the air coming from the vents is warm, the system could be low on refrigerant or the outdoor unit could be blocked by leaves or debris, and both of those need a contractor to sort out. Also check that all the outdoor unit's sides are clear of anything piled against it, since it needs open air to release heat.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first, since a wrong setting or dead batteries can look like a bigger problem. Next check the breaker panel and any power switch near the furnace or outdoor unit, since a tripped breaker or flipped switch will stop the system cold. Look at the air filter and replace it if it's dirty, since that alone causes a lot of the calls people make. If the system still won't run right after that, a contractor can diagnose what's left.
