What's included
What's Included in Ignition and Pilot Light Repair
Every ignition repair visit covers a full diagnostic of the ignition circuit plus the repair itself. Here's what's standard on the invoice and what we quote separately if it comes up.
Full Ignition Diagnostic
We pull the fault code, test igniter resistance with a multimeter, verify gas pressure at the valve with a manometer, and read flame sensor microamps. This tells us exactly which component failed instead of guessing.
Igniter or Thermocouple Replacement
Hot-surface igniters, spark igniters, and standing-pilot thermocouples are replaced with OEM-spec parts for your Carrier, Trane, Lennox, Goodman, Rheem, York, Bryant, or American Standard furnace.
Flame Sensor Cleaning or Swap
A carboned-up flame sensor is the most common cause of a furnace that lights then shuts off within seconds. We clean or replace it and verify the microamp reading is back in spec.
Gas Valve Pressure Check
We verify inlet and manifold gas pressure against the manufacturer's data plate. A valve running low will light inconsistently and can trip the board into lockout even with a new igniter.
Combustion Analyzer Verification
After the repair, we run a combustion analyzer on CO and flue temperature and give you the printed readout. This confirms the burner is firing clean and the heat exchanger isn't leaking.
Three-Cycle Test and Cleanup
We cycle the furnace three times to confirm it lights every time, vacuum the burner compartment, and walk you through what failed. Old parts and warranty paperwork go home with you.
Service overview
Furnace Ignition Repair Loveland CO: What It Covers
Furnace Ignition Repair Loveland CO is a diagnostic and repair service that restores the ignition sequence on gas furnaces - hot-surface igniters, intermittent pilot assemblies, spark igniters, flame sensors, and gas valves - so the burner fires when the thermostat calls for heat. When a furnace won't ignite, the board usually locks out after three failed attempts and the blower pushes cold air. We test the igniter with a multimeter, verify gas pressure at the valve with a manometer, and check the flame sensor's microamp reading before replacing anything.
Loveland sits at the mouth of the Big Thompson Canyon, where overnight temps swing 30 degrees and furnaces cycle hard from October through April. That cycling cooks igniters and carbons up flame sensors faster than in milder climates. If you're searching for pilot light repair near me Loveland during a cold snap, the odds are good your igniter has cracked or your flame sensor is reading below spec. We stock the common igniters and thermocouples on the truck, so most repairs finish in one visit.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How Our Ignition Repair Process Works
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone Triage
You call 970 489 0849 and describe what the furnace is doing - clicking, silent, short cycling, or blowing cold. We ask for the brand and approximate age, then book a same-day window. Most Loveland calls get a two-hour arrival window, and we text when the tech is en route.
Full Diagnostic
The tech pulls the burner door, checks the LED fault code on the control board, and tests the igniter with a multimeter. Gas pressure gets verified at the valve with a manometer, and the flame sensor is read in microamps. This takes 20 to 30 minutes and tells us exactly which part failed.
Upfront Quote
You get a flat price for the repair before we touch a tool. If the diagnosis turns up a second issue - a failing blower motor or a heat exchanger crack - we show you the reading and quote that separately. No surprise line items on the invoice.
Repair and Test
We install the new igniter, thermocouple, or gas valve, then run the furnace through three full ignition cycles to confirm it lights every time. A combustion analyzer verifies CO levels and flue temp. Typical repair time is 45 to 90 minutes once the diagnosis is done.
Cleanup and Walkthrough
We vacuum the burner compartment, replace the furnace filter if it's due, and walk you through what failed and why. You get the old part, the combustion readout, and the warranty paperwork before we leave. Any follow-up question is a phone call away.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Multimeter
Tests igniter resistance, thermocouple millivolt output, and flame sensor microamp readings. This is the tool that tells us which part actually failed instead of guessing.
Manometer
Verifies inlet and manifold gas pressure against the furnace data plate. Low gas pressure causes inconsistent ignition even with a brand-new igniter.
Combustion Analyzer
Reads CO levels and flue temperature after the repair. Confirms the burner is firing clean and the heat exchanger isn't leaking combustion gas into the supply air.
Inspection Camera
Lets us look inside the heat exchanger and burner compartment without pulling the whole assembly. Useful for spotting cracks, scale, and debris that affect ignition.
Nut Driver Set
Standard hand tool for pulling burner doors, igniter brackets, and flame sensor mounts on every major furnace brand without stripping screws.
Vacuum Gauge
Checks inducer draft pressure and confirms the pressure switch is seeing the vacuum it needs to allow ignition. A weak inducer will lock out the furnace.
Thermometer
Measures supply and return air temperature split to confirm the furnace is actually heating and not just running the blower.
Use cases
When to Call for Ignition Repair
These examples show how the service framework adapts rather than forcing every call through one repair.
Pilot Outage in Downtown Loveland
A Downtown Loveland homeowner was relighting the pilot every two days on an older standing-pilot furnace. The thermocouple was producing only 12 millivolts, well below the 25 needed to hold the gas valve open. Canyon drafts were making it worse. → We replaced the thermocouple, cleaned the pilot orifice, and adjusted the pilot flame to fully engulf the thermocouple tip. Output tested at 32 millivolts. The pilot held through the rest of the season with no relights. Repair cost: $240.
Flame Sensor Lockout in Centerra
A Centerra homeowner's high-efficiency furnace would light, run 8 seconds, then shut off and retry. After three tries it locked out. The flame sensor was reading 0.4 microamps - far below the 4.0 minimum. The sensor was heavily carboned. → We cleaned the flame sensor, verified microamps at 5.8, and ran a combustion analysis showing CO at 12 ppm and flue temp at 118 degrees. The furnace ran full cycles without shutdown. We also found a clogged condensate trap and cleared it. Total: $195.
Problems we solve
Ignition Problems We Fix in Loveland Homes
These are the no-heat calls we run most often in Loveland between October and April. If any of these match what your furnace is doing, call before it gets worse.
Furnace not igniting, blowing cold air
We test the igniter, flame sensor, and gas valve in sequence to find the actual failure point. Most no-ignition calls in Loveland trace to a cracked igniter or a flame sensor reading under 2 microamps. Both are same-day fixes.
Pilot light won't stay lit
We test thermocouple output with a multimeter and check the pilot orifice for debris. In Loveland, canyon drafts and negative pressure from tight construction are frequent causes. Replacement thermocouples are on the van.
Furnace short cycling on and off
We check flame sensor microamps, high-limit switch operation, and airflow restriction from a clogged furnace filter. Correcting the root cause stops the cycling and extends igniter life by years.
Furnace making banging noise at startup
We inspect igniter position, burner alignment, and gas pressure at the manifold. Correcting the ignition timing eliminates the delayed light and the bang. We verify with a combustion analyzer before we leave.
Pricing process
What Ignition Repair Costs in Loveland
$180 - $700 depending on the failed component and access
Failed Component Type
A hot-surface igniter is the cheapest common fix at $180 to $320 installed. A flame sensor runs $150 to $220. A gas valve is the most expensive at $350 to $700 because the part costs more and the job takes longer.
Furnace Brand and Age
Parts for Carrier, Trane, and Lennox are widely available and priced competitively. Older or discontinued models may need a specialty igniter that costs more and takes a day to source.
Access and Location
A furnace in a tight closet or attic takes longer to access than one in an open basement. That labor difference can add $50 to $150 to the job.
Customer reviews
What Loveland Customers Say
★★★★★
“Furnace quit on a Sunday night in January and the house was down to 58 by morning. Called at 7 a.m., tech was here by 10. Turned out the igniter was cracked and the flame sensor was reading almost nothing. He had both parts on the van and had us back to heat in about 90 minutes. Fair price, no upsell.”
★★★★★
“Our old Carrier furnace kept locking out and the pilot wouldn't stay lit. Two other companies told us we needed a whole new furnace. Loveland FurnaceRepair tested the thermocouple, replaced it for under $250, and it's run fine all winter. Honest diagnosis saved us thousands.”
★★★★★
“I manage six rentals in Centerra and use these guys for every no-heat call. They show up when they say, quote the price before starting, and send the combustion readout with the invoice. Had a gas valve fail on a Trane last month and they had it swapped the same afternoon.”
How much does Furnace Ignition Repair Loveland CO cost?
Most ignition repairs in Loveland run $180 to $450 in 2026, with the typical hot-surface igniter replacement landing around $220 to $320. Flame sensor cleaning is usually $150 to $200. Gas valve replacement pushes higher, $350 to $700, because the part costs more and the job takes longer. Diagnostic fee is credited toward the repair when you approve the work.
Why does my pilot light keep going out in Loveland CO?
A pilot that won't stay lit usually means a failing thermocouple, a dirty pilot orifice, or a draft pulling the flame off the thermocouple tip. In Loveland, canyon winds and negative pressure from tight new construction are common culprits. We test thermocouple millivolt output and check for backdraft before replacing anything. Most fixes take under two hours.
