Your furnace runs almost the whole year here
Park City needs heat from August through June. That is eleven months where the burner is the thing standing between your house and a 12 degree night. It cycles on and off for hours at a time, and every one of those starts puts wear on the igniter and the ignition control board. When one of those parts finally gives out, it usually happens on the coldest nights, because that is when the furnace is working hardest.
Summer is short and mild, with afternoons around 72°F, so the air conditioner gets little use most years. A system that sits idle for months can be slow to start when a hot stretch finally calls for it. Summit County also sees its share of winter storms and high wind, and with them, power outages. Most furnaces need electricity to run the blower and controls even on gas heat, so when the power drops on a cold night, the heat drops with it.

A new furnace and air conditioner would cut about $160 a year off heating and cooling for a typical Summit County home.
Estimates for a typical Summit County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Utah 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.
Utah requires HVAC contractors to hold a state license.
The Division of Professional Licensing tests HVAC contractors before they get that license, and it keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it follows them from one repair to the next. In Utah, work under $7,000 does not need a licensed contractor. That line is set by the state, not by how simple or safe the job looks.
A heating and cooling repair can fall on either side of that line depending on what it costs. Under $7,000, the person doing the work is not required to hold the state license. Above it, the license is what stands behind the repair, and gas connections are the part worth being careful about, since a bad one is what makes this kind of job dangerous.

- Why is my heat not working?
- Most furnaces stop for one of a few reasons. The igniter can fail, so the burners never light. A dirty flame sensor can shut the system off even when the flame is there. A clogged filter can starve the furnace of airflow until it overheats and shuts itself down. At 12°F on a winter night here, a furnace that will not stay lit needs a contractor out soon, since a house can lose heat fast at that temperature.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, the problem is usually with the refrigerant side, not the fan. A dirty coil, a low refrigerant charge, or a failed compressor can all leave you with air movement and no cooling. Check the outdoor unit first. If the fan on it is not spinning, or you hear it humming without turning, that points to the compressor or the fan motor rather than the coil.
- What can I check before calling for HVAC repair?
- Start with the filter. A filter clogged with dust cuts off airflow and can make a furnace or air conditioner shut down on its own. Next check the thermostat, since a dead battery or a setting left on the wrong mode will look like a bigger problem than it is. If the system is electric, check the breaker too. If none of that explains it, a contractor will need to look at the parts inside the unit.
