Furnace Igniter Repair Services in Sandy, Utah
Honest recommendations, professional workmanship, and transparent pricing you can trust.
When your furnace runs but never actually lights, a failed igniter is one of the most common reasons. It is a small part, but without it your furnace cannot produce heat, and on a cold night that is not something you want to wait on. We provide furnace igniter repair services near you in Sandy, UT. We diagnose the real cause, replace a failed igniter with the correct part for your furnace, and get your heat back on, often the same day. Our licensed technicians give you an upfront, flat-rate price before any work begins, and we are available after hours when your furnace goes out at night.
What Does a Furnace Igniter Do?
The igniter is the part that lights your furnace’s burners. When your thermostat calls for heat, the igniter heats up and ignites the gas so your furnace can start producing warm air. Most modern furnaces use a hot surface igniter, a small element that glows red hot, while some use a spark igniter instead. Either way, if the igniter fails, the gas never lights. That is why a bad igniter usually means no heat at all, even though the rest of the furnace sounds like it is trying to start.
Signs Your Furnace Igniter Needs Repair
A failing igniter has some fairly clear symptoms. Call us if you notice:
- No heat, or a furnace that runs but never lights
- Cold air coming from the vents even though the furnace is running
- The furnace trying to start, then failing to ignite
- Repeated clicking, or the furnace cycling on and off without heating
- A blinking error light on the furnace that points to an ignition problem
- The furnace starting, running briefly, then shutting down and locking out
- An older igniter that has been slow or intermittent lately
Why Furnace Igniters Fail
Igniters wear out, and a few things speed that up:
- Normal wear. Hot surface igniters are brittle and degrade a little with every heating cycle, so they simply have a limited lifespan.
- Cracks or hairline fractures. A tiny crack in the element stops it from heating properly.
- Dirt or oils on the element. Even the oils from a bare hand can create a hot spot and shorten its life, which is one reason it is worth leaving to a technician.
- Power surges. A voltage spike can damage the igniter or the control that runs it.
- A dirty flame sensor. When the sensor cannot confirm a flame, the furnace keeps trying to reignite, which wears the igniter out faster.
Because a Sandy winter keeps your furnace cycling for months, igniters here tend to see plenty of use.
Repair or Replace the Igniter? We Diagnose First
A furnace that will not light does not always come down to the igniter. Before we replace anything, we test the igniter, the gas supply, the flame sensor, and the control board to confirm what is actually stopping ignition. Sometimes the real fix is a dirty flame sensor or a safety switch, not the igniter. If the igniter has cracked or burned out, we replace it, since a hot surface igniter cannot be repaired once it fails, and we use the correct part for your furnace. Either way, we show you what we found and give you honest options, along with our furnace repair service if the problem turns out to be something else.
How We Repair Your Furnace Igniter
- Schedule your service: Call (801) 509-9331 or book online at a time that works for you.
- We diagnose the cause: We confirm whether the igniter is the problem, or whether something else, like the flame sensor or control board, is stopping ignition.
- We replace it with the correct part: We install the right igniter for your furnace, handling it carefully so skin oils do not shorten its life.
- We test the full sequence: We run the furnace through a complete ignition and heating cycle and confirm the safety controls work.
- We make sure you have heat: We verify the furnace is lighting reliably and heating your home before we leave.
Because a furnace igniter involves both gas and electrical connections, this is a job for a licensed technician rather than a DIY fix.

A hot surface igniter cannot be repaired once it cracks or burns out, so it is replaced. We confirm the igniter is the cause first, then install the correct part.
How much does furnace igniter replacement cost?
It depends on the igniter type and your furnace model, but it is one of the more affordable furnace repairs. We give an upfront, flat-rate price, and we can often fix it the same day.

Yes. When your furnace goes out at night, we can help, and an after-hours fee applies to calls after 5pm.
