Ten months of heat, one month of cooling
Your furnace carries this house September through June. On winter nights that average 14°F, it cycles on and off for hours to hold the temperature, and every cycle puts wear on the igniter and the blower motor. When one of those fails on a night that cold, you find out fast.
The air conditioner gets one real month of work, in July, with afternoons averaging 79°F. A system that sits idle most of the year can develop problems that only show up the first time it has to run, so a weak capacitor or a low refrigerant charge often waits until that first hot week to announce itself. Madison County has seen 103 winter storms and 60 damaging wind events over the past ten years, and outages that follow can knock out a furnace's ignition system even when the rest of the house still has power.

A new furnace and air conditioner would cut about $100 a year off heating and cooling for a typical Madison County home.
Estimates for a typical Madison County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Idaho 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.
Idaho requires HVAC contractors to hold a state license.
Idaho tests the contractor and keeps a record of who holds that license, through the HVAC Board. It is issued to the contractor, not to each job, so the same license covers this repair and whatever comes after it.
That license is what stands behind the person working on your system. Since Madison County falls under the state's rule, the license itself, not a separate county sign-off, is what the state checked before this contractor was allowed to take on heating and cooling work.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the igniter, or the power to the unit. Check that the thermostat is set to heat and the temperature is above room temperature. Check your breaker panel, since a tripped breaker will shut the whole system down. If the furnace runs but no warm air comes out, or it tries to start and shuts off again, that points to the igniter or a safety switch, and a contractor will need to look at it. With winter lows here averaging 14°F, a furnace that will not hold on is not something to wait out.
- Why is my system running but not cooling the house?
- Start with the filter. A clogged filter chokes off airflow and the air conditioner cannot pull enough heat out of the house even though it keeps running. Check the outdoor unit too, and clear away any leaves or debris blocking it. If the filter is clean and the outdoor unit is clear but the air coming out is not cold, the system may be low on refrigerant or have a failing part, and that needs a contractor to check.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set correctly and the batteries are not dead. Check your breaker panel for a tripped breaker, and check the filter, since a dirty filter causes problems in both summer and winter. If the system has a switch nearby that looks like a light switch, make sure it has not been bumped off. If you have checked these and the system still is not working right, a contractor will need to diagnose it further.
