Furnace Heat Exchanger Repair Pocatello ID
A plain-language look at what Furnace Heat Exchanger Repair involves and when it is needed.
See how it worksFurnace heat exchanger repair Pocatello ID is the process of inspecting, cleaning, or replacing the metal component that separates combustion gases from your home's breathable air. A cracked heat exchanger can leak carbon monoxide, so we start with a combustion analyzer and visual inspection of the entire exchanger. If the crack is small and accessible, we clean and seal it. If the metal is fatigued or warped, we recommend heat exchanger replacement Pocatello Idaho to restore safe operation.
Pocatello winters push furnaces hard from October through March, and that constant cycling stresses heat exchanger metal. Homes in older neighborhoods like Old Town and the University Area often have 15- to 25-year-old furnaces where cracked heat exchanger symptoms Pocatello ID show up as headaches, soot, or a yellow flame. We also see furnace limit switch tripping and furnace short cycling when airflow is restricted. If you search furnace heat exchanger repair near me Pocatello ID, we're the local crew that answers.
A cracked heat exchanger leaks carbon monoxide, so testing comes before any repair.
- What it is
- Repair or replacement of the metal component that separates combustion gases from your home's air.
- When you need it
- When you see a yellow flame, soot, headaches, or your CO alarm sounds.
- What to expect
- A combustion test, camera inspection, written quote, and repair or replacement.
Our Heat Exchanger Repair Process
We follow a five-step process that starts with safety testing and ends with a furnace you can trust. Every visit includes clear explanations, so you understand what we found and what we did.
-
Safety Check
We start by testing for carbon monoxide at the supply registers and in the flue. A gas leak detector and combustion analyzer give us baseline numbers. If CO is present in your living space, we shut the furnace down immediately and ventilate the area before continuing.
- CO test
- Gas leak check
- Baseline readings
-
Full Inspection
Next we pull the blower assembly and inspect the heat exchanger with a borescope camera. We check for cracks, rust, soot streaks, and warping. We also test the flame sensor, thermocouple, and limit switch. This takes 45 to 90 minutes depending on furnace access.
- Borescope camera
- Flame sensor test
- Limit switch check
-
Repair or Replace
If the crack is minor and accessible, we clean the exchanger and apply a high-temp sealant rated for 2,000 degrees Fahrenheit. If the metal is fatigued, we quote heat exchanger replacement Pocatello Idaho. Most replacements take four to six hours and include new gaskets and fasteners.
- Seal or replace
- New gaskets
- OEM parts
-
Reassembly and Testing
After repair or replacement, we reassemble the furnace, check the inducer motor and blower motor capacitor, and fire the unit. We run it through three full heating cycles, watching for flame rollout, short cycling, and proper temperature rise. You see the readings before we button up.
- Three cycles
- CO re-test
- Draft check
-
Walkthrough and Report
We walk you through what we found, show you the before-and-after combustion readings, and explain any maintenance you should do. You get a written report with part numbers and test results. If you need a follow-up, we schedule it before we leave.

Tools and Methods We Use
Move across a circle, or focus it and press Enter, for an illustrative thermal view of the photograph.
Combustion Analyzer
Measures carbon monoxide, oxygen, and temperature in the flue and supply air. It tells us if the heat exchanger is leaking and how efficiently the furnace burns fuel.
Borescope Camera
Lets us see inside the heat exchanger without disassembling the entire furnace. We use it to find cracks, rust, and warping, and we show you the footage.
Gas Leak Detector
Sniffs out gas leaks at connections, the gas valve, and burner assembly. Fast and accurate, it helps us confirm safety before we test the exchanger.
Manifold Gauge Set
Checks gas pressure at the valve and burners. Proper pressure prevents overheating and extends heat exchanger life.
Multimeter and Clamp Meter
Tests electrical components like the flame sensor, thermocouple, limit switch, and control board. We verify each part before condemning the exchanger.
Thermal views are illustrative, generated from the photographs.
Methods
Blower Motor Capacitor Tester
Checks the capacitor that starts the blower motor. A weak capacitor restricts airflow and overheats the heat exchanger.
Anemometer
Measures airflow at registers and the blower. Proper airflow keeps the heat exchanger from overheating and cracking.
ACCA Quality Standards
We follow ACCA quality standards for airflow, combustion, and safety testing.
NATE Certification Protocols
That means consistent, reliable results every time, no matter which brand of furnace you own.
EPA Section 608 Safety Practices
We follow EPA Section 608 handling practices for combustion safety and refrigerant. These rules protect your home and our techs during every heat exchanger repair.
Idaho HVAC Contractor License Compliance
We pull permits when required and ensure every repair meets local Pocatello code.
When You Need Heat Exchanger Repair
CO alarm call
Your CO alarm goes off while the furnace is running in your Pocatello home.
Shut the furnace off, open windows, and call (208) 764-8111. We dispatch a tech with a combustion analyzer and gas leak detector. We test the exchanger, confirm the leak, and repair or replace it the same day if possible.
Outcome: You get a safe furnace and documented CO readings proving your home is protected.
Old furnace cold air
Your furnace is 18 years old and blows cold air, but the flame sensor looks clean.
We inspect the heat exchanger with a borescope camera. At that age, cracks are common. We quote repair versus replacement with clear pricing, then complete the work in one visit.
Outcome: You either get a sealed exchanger or a new one, plus a furnace that heats reliably.
Tenant headaches
You're a landlord in Chubbuck and your tenant reports headaches when the heat runs.
We prioritize safety calls. Our tech tests CO levels, inspects the exchanger, and provides a written report you can share with tenants. We repair or replace the exchanger and verify safe operation.
Outcome: Your tenant gets safe heat, and you get documentation showing the furnace passed testing.
Short cycling
Your furnace short cycles every few minutes and the limit switch keeps tripping.
We check airflow, the blower motor capacitor, and the heat exchanger. Restricted airflow often causes overheating. We restore airflow, repair any exchanger damage, and test the limit switch.
Outcome: Your furnace runs longer, heats evenly, and stops tripping the limit switch.
Metallic smell
You smell a metallic burning odor when the furnace runs in your University Area home.
That smell often means the heat exchanger is overheating or cracking. We inspect it with a camera, test combustion, and repair or replace the exchanger. We also check the air filter and blower motor.
Outcome: The odor is gone, and your furnace runs safely with proper airflow.
How Heat Exchanger Repair Works in Pocatello
Pocatello winters are long and cold, with temperatures dropping below zero from December through February. That constant demand stresses furnace heat exchangers, especially in older homes in Old Town and the University Area where furnaces often run 20 years or more. We see cracked heat exchanger symptoms Pocatello ID homeowners describe as headaches, soot, or a yellow flame.
Homes at higher elevations like Pocatello Heights and Gibson Jack deal with altitude-related combustion issues that can accelerate exchanger wear. We adjust gas pressure and airflow to compensate. If you need furnace heat exchanger repair in Tyhee or anywhere in Bannock County, we bring the right tools and parts.
We also check for furnace limit switch tripping and furnace short cycling, which are common when air filters are neglected. Our local experience means we know which neighborhoods have harder water, older ductwork, or drafty crawlspaces that affect furnace performance. Call (208) 764-8111 for a diagnostic.
- Old Town Pocatello: Many homes here have original furnaces from the 1980s and 1990s. Heat exchanger cracks are common, and we often recommend replacement.
- Highland Area: Newer construction with tight envelopes. We check for negative pressure issues that can pull CO into living spaces if the exchanger cracks.
- Chubbuck: Mix of rentals and owner-occupied homes. We provide written reports for landlords and test CO levels on every visit.
- Tyhee: Rural properties often use propane furnaces. We adjust gas pressure and inspect exchangers for heat stress from propane combustion.
- University Area: Older homes with retrofitted furnaces. We see undersized ductwork that restricts airflow and overheats heat exchangers.
- Sub-zero winter temperatures: Furnaces run constantly, expanding and contracting the heat exchanger until cracks form. We test CO levels and inspect for fatigue.
We walk through your concerns and furnace history We lay drop cloths and set up tools We review findings and next steps
From problem to finished result.
Cracked Exchanger in Old Town Bungalow
Before: A 1920s bungalow in Old Town had a 22-year-old furnace blowing cold air. The homeowner reported headaches and a metallic smell. CO readings in the supply air were 18 ppm, well above safe limits.
After: We replaced the cracked heat exchanger with an OEM-spec unit. Post-repair CO readings dropped to 2 ppm. The furnace now heats the home evenly, and the homeowner no longer gets headaches.
We recommended a new air filter every 90 days and an annual combustion test. Keeping airflow clean prevents the new exchanger from overheating.
Short Cycling Fixed in Chubbuck Rental
Before: A Chubbuck rental furnace short cycled every four minutes. The limit switch tripped repeatedly, and the heat exchanger showed early signs of warping. The tenant complained of uneven heating.
After: We replaced the blower motor capacitor, cleaned the flame sensor, and repaired a small crack with high-temp sealant. The furnace now runs 15-minute cycles, and CO readings are at 1 ppm.
We set the tenant up with a filter replacement schedule and a reminder for annual service. Landlord gets a written report each year.
Emergency CO Call in Highland Area
Before: A family in Highland Area called at 11 p.m. when their CO alarm went off. The furnace was still running. We walked them through shutting it down and ventilating the home.
After: Next morning we confirmed a cracked heat exchanger near the burners. We replaced it with a Lennox-compatible unit and tested CO levels at 0 ppm. The family had safe heat by 3 p.m.
We installed a new CO alarm near the furnace and recommended annual combustion testing. They now schedule service every October.
Heat Exchanger Problems We Solve in Pocatello
A failing heat exchanger shows up in different ways, and each one needs a specific fix. We diagnose the root cause, repair or replace the exchanger, and verify your furnace is safe before we leave.
- Cold airFurnace blowing cold airCold air usually means the heat exchanger is cracked or the flame sensor is dirty. Running the furnace can spread carbon monoxide through your home. We test the flame sensor and inspect the exchanger with a camera. If the sensor is dirty, we clean it. If the exchanger is cracked, we repair or replace it and verify CO levels are safe.
- Short cyclingFurnace short cyclingShort cycling overheats the heat exchanger, causing cracks and warping. It also drives up your energy bill and shortens furnace life. We check airflow, the limit switch, and the blower motor capacitor. Restricted airflow is often the culprit. We restore proper airflow and inspect the exchanger for damage.
- Strange noisesFurnace making strange noisesBanging, rumbling, or screeching can indicate a cracked heat exchanger, a failing blower motor, or a loose inducer motor. Ignoring it risks CO leaks. We isolate the noise source, test the blower motor and inducer motor, and inspect the exchanger. We repair the failed component and verify the exchanger is intact.
- Limit switch trippingFurnace limit switch trippingA tripping limit switch means the furnace is overheating, which cracks the heat exchanger over time. It can also cause the furnace to shut down entirely. We test the limit switch, check airflow, and inspect the exchanger for cracks. We replace the switch if needed and repair any exchanger damage we find.
- Ignition failureFurnace ignition failureIgnition failure leaves you without heat and can stress the heat exchanger as the furnace tries to light repeatedly. It may also indicate a gas valve issue. We test the igniter, flame sensor, and gas valve. If the exchanger is cracked, we repair or replace it. If ignition components failed, we replace them and restore reliable heat.
