What Our Heat Exchanger Service Includes
Every heat exchanger job starts with a full diagnostic. What we find determines what we do. Here's what's covered in a standard visit - and what's quoted separately if needed.

Work order
Furnace Heat Exchanger Repair- Camera Inspection: We insert a borescope camera into the heat exchanger to look for cracks, holes, and corrosion. This is the only way to confirm a heat exchanger failure without pulling the whole unit. You see the footage on our screen.
- Combustion Analysis: A combustion analyzer measures CO, CO2, and oxygen levels in the flue gas. High CO readings or abnormal oxygen levels point to a heat exchanger problem. We test before and after any repair to confirm the fix worked.
- Heat Exchanger Repair or Replacement: If the crack is accessible and the furnace is worth saving, we repair or replace the heat exchanger. If the unit is too old or the damage is too extensive, we quote a full furnace replacement instead. You decide.
- Component Check: While we're in the furnace, we check the igniter, flame sensor, thermocouple, blower motor, control board, and limit switch. If any of these are failing, we let you know. Replacing them now saves a second service call later.
- Safety Test: After the repair, we run the furnace through a full heating cycle and test CO levels in the supply air and flue. We confirm the flue is drafting properly and the limit switch is working. You get a written summary of the test results.

Furnace Heat Exchanger Repair Severance CO
A cracked heat exchanger is a safety issue, not a wait-and-see problem. We inspect it properly, show you what we find, and fix it right. That's how you keep your family safe and your furnace running.
Furnace heat exchanger repair in Severance means finding the crack, hole, or corrosion that's letting combustion gases mix with your home's air. The heat exchanger is a metal shell inside your furnace - it separates the burner flame from the air your blower pushes through the ducts. When it fails, you're not just losing heat; you're risking carbon monoxide in your living space. We use an inspection camera and combustion analyzer to confirm the problem before we quote anything.
Severance homes take a beating from Colorado's freeze-thaw cycles. Furnaces here run hard from October through April, and that constant expansion and contraction is what cracks heat exchangers over time.

We see cracked heat exchanger repair in Severance, Colorado on everything from 1990s Carrier units to newer Goodman and Rheem furnaces.

How Our Heat Exchanger Service Works
Five steps from your first call to a safe, working furnace. No guesswork, no pressure.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Measures CO, CO2, and oxygen in the flue gas. High CO or abnormal oxygen readings point to a heat exchanger problem.
Tests the flue for proper draft and combustion efficiency. A blocked or leaking flue can stress the heat exchanger.
Tests gas pressure at the valve and burners. Incorrect pressure can cause incomplete combustion and heat exchanger damage.
Tests electrical components - control board, blower motor, igniter, flame sensor. We use it to rule out electrical issues before condemning a heat exchanger.

How Heat Exchanger Service Works in Severance
Severance sits in Weld County, and our climate is hard on furnaces. Winter temperatures drop below zero regularly, and the freeze-thaw cycles in fall and spring stress metal components.
Severance High School Area
Newer homes here often have high-efficiency furnaces with sealed combustion chambers. Heat exchanger inspection requires specific tools and training.
Weld County Road 74 Corridor
Mix of older and newer homes. We see everything from 1990s Carrier furnaces to recent Trane installs. Heat exchanger failures are common in the older units.
Eaton Town Line
Rural properties here often use propane furnaces. Propane burns hotter than natural gas, which can stress heat exchangers faster.

PhotoCracked Heat Exchanger in 12-Year-Old Carrier
Before: A Severance homeowner called us because their CO detector went off twice in one week. The furnace was a 12-year-old Carrier that had never been inspected. We found a 3-inch crack in the heat exchanger and CO levels at 45 ppm in the supply air.
After: We replaced the heat exchanger and tested combustion after the repair. CO levels dropped to 0 ppm in the supply air. The furnace is now running safely, and the homeowner has a written inspection report for their records.
Furnace Blowing Cold Air in Windsor
Before: A Windsor family called us in January because their furnace was blowing cold air. The thermostat was set to 70 but the house wouldn't get above 62. We diagnosed a cracked heat exchanger and a failed blower motor.
After: We replaced both the heat exchanger and the blower motor. The furnace now heats the home to 70 degrees in under 30 minutes.
CO Alarm in Older Goodman Furnace
Before: A Greeley rental property had a Goodman furnace from the early 2000s. The tenant reported headaches and nausea when the heat ran. The CO detector showed elevated levels. We found a cracked heat exchanger and a blocked flue.
After: We replaced the heat exchanger and cleared the flue blockage. CO levels returned to zero. The property manager avoided a full furnace replacement and the tenant stayed in the unit.
Heat Exchanger Problems We Solve in Severance
These are the calls we get most often from Severance and Weld County homeowners. If any of these sound familiar, don't wait.
Furnace blowing cold air
A cracked heat exchanger can cause the furnace to short-cycle or lock out, leaving you with no heat when you need it most.
Carbon monoxide detector going off
A CO alarm means combustion gases are entering your home. This is a life-safety issue - leave the house and call for help immediately.
Furnace banging or popping noise
Banging noises often mean the heat exchanger is expanding and contracting unevenly - a sign of cracks or blockages.
Yellow or flickering burner flame
A healthy gas flame is blue. Yellow or flickering flames mean incomplete combustion, which produces carbon monoxide and stresses the heat exchanger.
Furnace leaking water
Water around the furnace can mean a clogged condensate line, but it can also indicate a cracked heat exchanger in high-efficiency units. Both need attention.

What Severance Homeowners Say
Our furnace started blowing cold air in January and we couldn't figure out why. Called these guys - they came out same day, pulled the blower, and showed us a crack in the heat exchanger on their camera. Quoted us repair and replacement. We went with repair since the furnace was only 9 years old. Heat's been working fine since. Straight shooters.
Our CO detector went off at 6 a.m. on a Saturday. We called Severance Furnace Repair Pros and they had a tech out within two hours. He confirmed the heat exchanger was cracked and shut the furnace down. Came back Monday with the replacement part. I appreciated that they treated it like the emergency it was.
I manage several rental properties in the Severance and Greeley area. I've used these guys for heat exchanger issues on a few older furnaces. They're honest about when a repair makes sense and when it's time to replace. Their pricing is fair and they document everything. Good outfit.
