Layton furnaces run long and hard from October to May
Your furnace works eight months of the year here, longer than in most places. On winter nights averaging 22°F, it cycles on and off many times to hold the house at temperature. Each start puts a load on the igniter and the flame sensor, and over eight months that adds up faster than it would somewhere milder.
Most homes in Davis County heat with gas, so when the furnace won't light or won't stay lit, there is no backup warming the house. Winter storms in this area have knocked out power before, and a furnace with no power will not run even if the gas is on. If yours is short cycling, blowing cold air, or not turning on at all, that is the strain of a long heating season catching up with a worn part.

A new furnace would cut about $110 a year off heating for a typical Davis County home.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
Utah requires HVAC contractors to hold a state license.
The Division of Professional Licensing issues that license, and it covers the contractor, not each job, so the same license applies whether they're replacing an igniter or putting in a new furnace. Work under $7,000 does not need a licensed contractor under Utah's rule, and most furnace repairs fall under that amount.
Most homes in Davis County heat with gas, and furnace repair often means working on a gas connection, which is the part of the job where a mistake is dangerous, not just costly. Above $7,000, the license is what stands behind that work. Below it, Utah's rule does not require the contractor to hold one.

- Why won't my furnace turn on?
- Most often it's the thermostat, the power supply, or the gas supply to the unit. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Check the switch on the furnace itself, it looks like a light switch on or near the unit, and make sure it's on. If the breaker for the furnace has tripped or the gas valve got shut off, that will keep it from starting too. With winter lows here averaging 22°F, a furnace that won't start is worth calling in on the same day.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running its fan without the burners lighting. That points to an ignition problem, a flame sensor that isn't reading correctly, or the furnace shutting itself off partway through the cycle. It can also mean the thermostat fan setting is on instead of auto, which just circulates room air with no heat behind it. A contractor can tell which one it is from the furnace's behavior when it's running.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit usually means the thermocouple isn't sensing the flame anymore, so the gas valve shuts it back off. A draft blowing across the pilot or a dirty pilot opening can also put it out. This is a gas furnace part, and 86.4% of homes in Davis County heat with gas, so it's a common call here. Don't keep relighting it repeatedly, have a contractor look at the thermocouple and the pilot assembly.
