Heating and Cooling Repair in Post Falls

Frontier HVAC Repair fixes furnaces, heat pumps and central air conditioners in Post Falls and in the towns around it: Coeur d'Alene, Hayden, Rathdrum, Spirit Lake and Dalton Gardens.

When a furnace stops heating, the cause is usually one part: an igniter that cracked, a flame sensor coated with residue, a pressure switch, an inducer or blower motor, or a control board. When a heat pump quits in winter, it is usually ice on the outdoor coil, a defrost board or a reversing valve. When central air quits on the first hot week of summer, it is usually a capacitor, a contactor or a condenser fan motor.

Post Falls homes are mostly young, so electronic controls fail more often than worn mechanical parts. Older houses in Coeur d'Alene and Dalton Gardens bring the opposite: tired blowers, metal flues and original ductwork.

Why Furnaces and Heat Pumps Fail in Post Falls

The heating season is long, so furnaces and heat pumps rack up long run times and wear out igniters, motors and capacitors. Heat pumps spend much of the winter running defrost cycles, which is why defrost controls and reversing valves fail here.

Air conditioners sit idle most of the year and fail on the first hot days of July.

Heating and AC Repair Questions

What are the most common HVAC repairs?

On a furnace: igniters, flame sensors, pressure switches, inducer motors, blower motors and their capacitors, and control boards. On an air conditioner or heat pump: run capacitors, contactors, outdoor fan motors, frozen or dirty coils and clogged condensate drains. Thermostat wiring and tripped breakers are the simple causes that look like a big failure.

How often should your HVAC system be serviced?

A furnace or heat pump that heats a North Idaho house from October into April should be serviced every year, ideally before the first hard freeze. A home with central air and a heat pump runs most of the year, so it gets the most out of a check before heating season and another before cooling season. Filters get changed far more often than either visit.

What is considered old for an HVAC?

It depends on the equipment. Gas furnaces outlast air conditioners and heat pumps because the outdoor units sit in the weather and heat pumps run in both seasons. Age matters less than condition: rust in the heat exchanger area, a compressor that struggles to start, or repeated failures of the same part say more than the date on the data plate.

How do you know if the problem is the thermostat or furnace?

If the thermostat screen is blank, the batteries or the low-voltage power to it are the first suspects. If the thermostat calls for heat and you hear nothing at the furnace, the problem is usually the furnace, its door switch or the wiring between them. If the furnace starts, lights and runs but shuts off before the house warms up, the cause is almost always in the furnace, not the thermostat.

Do furnaces last longer than AC?

Usually, yes. A gas furnace sits indoors out of the weather and only works in the heating season, while an AC condenser sits outside through snow, ice and summer heat. In North Idaho the furnace does far more work, so its motors and igniter wear faster than the furnace cabinet itself, but the furnace as a whole still tends to outlast the outdoor unit.

What is the most common part to fail on HVAC?

The run capacitor. It helps start and run the blower motor, the outdoor fan motor and the compressor, and heat wears it out. A weak capacitor shows up as a humming motor that will not start, an outdoor fan that does not spin or a furnace blower that runs slow. On gas furnaces, the igniter and flame sensor come next.
