Ten months of work a year, in a place that loses power
Fernley asks a lot of a heating and cooling system. Heat runs October through May, eight months, and on winter nights that average 23°F the burner is cycling on and off most of the night to keep up. Cooling only has to carry July and August, but summer afternoons average 87°F and that is where a weak capacitor or a low refrigerant charge shows up first, usually as a system that runs and runs but never quite gets the house down to temperature.
Most homes here heat with gas, so the parts that light and sense that flame, the igniter and the flame sensor, are doing the most work of anything in the system. Lyon County also sees real weather, 126 winter storms and 305 damaging wind events over the last ten years, and in Nevada about 13% of households lost power for a full day or more in 2024. A furnace or air conditioner that sits through an outage like that can need a reset, or turn out to have a problem that was already there before the power went out.

A new furnace and air conditioner would cut about $140 a year off heating and cooling for a typical Lyon County home.
Estimates for a typical Lyon County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Nevada 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.
Nevada requires HVAC contractors to hold a state license.
The Nevada State Contractors Board tests and records the contractor before that license is issued. It covers the business doing the work, not the specific repair being done, so the same license carries across different jobs for the same contractor.
For a repair like this, that license is what stands behind the person working on your system. It is the state's record that the contractor was tested and is accountable for the work done in your home, on this job as on any other.

- Why is my heat not working?
- The most common cause is the igniter or flame sensor failing to start the burners, especially if the furnace clicks or tries to start but shuts off again. A dead thermostat battery or a tripped breaker can also stop the furnace cold, and both are worth checking first. With winter nights here averaging 23°F, a furnace that will not stay lit needs a contractor to look at it, since the fix depends on which part failed.
- Why is my system running but not cooling the house?
- If the blower runs but the air is not cold, check the filter first. A clogged filter blocks airflow across the coil, and when that happens the coil can freeze over and stop cooling the house even though the fan is still moving air. A dirty outdoor unit or a refrigerant leak can cause the same thing, and a contractor will need to check the coil and the refrigerant charge to know which one it is.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to heat or cool as needed and that the batteries are not dead, since a blank or unresponsive display can look like a furnace or air conditioner problem when it isn't one. Next check the breaker for the system, and check the filter, since a filter clogged with dust can choke off airflow and make the system seem like it is failing. If the system still is not heating or cooling after that, a contractor will need to diagnose it further.
