What our Propane Furnace Repair includes
Every propane furnace repair call includes a full diagnostic, a written price before work starts, and a post-repair test.
Work order
Propane Furnace Repair- Full ignition diagnostic: We test the igniter, flame sensor, thermocouple, gas valve and control board in sequence with a multimeter and thermocouple tester. You get the actual failure, not a guess, and the diagnostic covers the whole safety circuit, not just the part that tripped.
- Combustion and CO check: A flue gas analyzer reads oxygen, carbon monoxide and stack temperature, and we compare the numbers to the manufacturer spec for your model. This is how we catch a furnace running rich or a heat exchanger that is starting to leak before it becomes a health problem.
- Manifold pressure set to altitude: Severance sits near 4,900 feet, and propane furnaces need the correct manifold pressure and burner air for that elevation. We set it with a manometer and verify the flame color and shape after the adjustment. This is the step most quick repair calls skip.
- Airflow and blower check: We measure static pressure and blower amp draw, inspect the blower wheel and capacitor, and check the filter. Restricted airflow overheats the heat exchanger and shortens the life of the furnace, so we fix airflow problems while we are already in the unit.
- Post-repair heat cycle test: After the repair, we run the furnace through a complete heat cycle and watch it from ignition to blower shutdown. If anything is still off, we catch it before we pack up. You get the readings we took and a plain explanation of what failed.

What Propane Furnace Repair in Severance covers
A propane furnace that runs rich, shorts cycles or bangs on startup is telling you something is wrong. Fixing it properly the first time costs less than replacing parts by guess and keeps your family warm and safe.
Propane Furnace Repair in Severance is the diagnostic and repair work that gets an LP-fired furnace running safely again: testing the igniter, thermocouple, flame sensor, gas valve, control board, blower motor and heat exchanger, then replacing or recalibrating whatever has failed. Propane burns hotter and wetter than natural gas, so LP systems carbon up faster, pilot assemblies foul sooner, and regulators drift out of spec. We check combustion with a flue gas analyzer, verify manifold pressure with a manometer, and confirm airflow before we call a job done.
Severance sits at roughly 4,900 feet in Weld County, and that altitude changes how a propane furnace breathes. Thin air means the burner needs a different air-to-fuel ratio, and units set up at sea level often run rich here, sooting the heat exchanger and tripping the limit switch. Add a January cold snap that pushes the furnace to run nonstop for a week, and small problems turn into no-heat calls fast. If you're searching for Propane Furnace Repair near me Severance CO at 11 p.m., we answer and dispatch.

How our propane furnace repair process works
You call, we show up when we say we will, and you get a straight answer before any work starts.
Tools and methods we use on propane furnaces
Each method answers a different question. Together they leave very little to guess.
Reads oxygen, carbon monoxide and stack temperature at the flue. This is how we confirm the burner is running clean and catch a failing heat exchanger before it becomes a safety issue.
Tests voltage and continuity through the ignition circuit, control board outputs, blower motor and safety switches. It is how we find the actual failed component instead of replacing parts by guess.
Reads the millivolt output of a standing pilot thermocouple so we know whether it is weak or the gas valve is the problem on older propane furnaces.
Lets us look inside the heat exchanger and flue passages without pulling the furnace apart, which is how we confirm cracks and blockages on a safety inspection.

How propane furnace repair runs in Severance
Severance sits at about 4,900 feet in Weld County, and that elevation is the single biggest factor in how a propane furnace performs here. Units set up at low elevation run rich, soot the burner and heat exchanger, and trip the limit switch.
Downtown Severance
Older housing stock with more standing-pilot propane furnaces. Expect thermocouple, pilot assembly and draft work more often than control board failures.
East Severance new builds
Newer high-efficiency condensing propane furnaces. Common calls here are pressure switch faults, condensate drain clogs and flame sensor fouling.
County road properties
Shop and outbuilding propane unit heaters with venting and combustion air problems. We check clearances and make sure the space gets enough air.

PhotoNo-heat call in January
Before: A propane furnace in Severance was blowing cold air with the thermostat calling for heat. The homeowner had already replaced the filter with no change, and the house had dropped to 57 degrees overnight.
After: We found a cracked hot surface igniter and a flame sensor reading below spec. Both were replaced from truck stock, manifold pressure was reset for altitude, and the furnace held 68 degrees within three hours of the call.
Short cycling and high propane use
Before: A Windsor home's propane furnace was short-cycling every few minutes and the propane bill had climbed about 20 percent over the previous winter. The limit switch was tripping repeatedly.
After: We cleaned the burner and coils, corrected a restricted return, and set manifold pressure to the spec for 4,900 feet. The furnace now runs full cycles, and the homeowner reported noticeably shorter run times.
Banging furnace in a rental
Before: A rental property in Eaton had a propane furnace that banged loudly on every startup. The tenant had complained twice, and the owner was worried about the heat exchanger.
After: We diagnosed delayed ignition, cleaned and adjusted the burner assembly, and verified combustion with a flue gas analyzer. The banging stopped, and the heat exchanger passed inspection with no cracks found.
Propane furnace problems we fix in Severance
Propane furnaces fail in predictable ways, and altitude makes some of them worse.
Furnace blows cold air with the thermostat calling for heat
The burner never lights, so the blower pushes unheated air through the house and the temperature keeps dropping.
Pilot light will not stay lit on an older propane furnace
A standing pilot that keeps going out means no heat and, worse, a possible gas smell if the valve is not closing cleanly.
Furnace banging or booming on startup
A boom at ignition usually means delayed ignition, where gas builds up before it lights.
Furnace leaking water around the base
Propane furnaces produce more condensate than gas units, and a clogged drain or a failed inducer can send water onto the floor.
Furnace short-cycling and never reaching setpoint
Short cycles wear out the igniter, blower motor and control board faster, and they burn more propane for less heat.
Why Severance homeowners call us for LP furnace work
Propane furnaces fail in specific ways, and guessing wastes money. Here is what a proper repair gets you.
Heat back the same day
Most no-heat calls we run in Severance are diagnosed and repaired in one visit, usually two to four hours on site.
Safe combustion, verified
A cracked heat exchanger or a blocked flue can push carbon monoxide into your home.
Lower propane bills
A furnace running rich or short-cycling burns more fuel for less heat.

What Severance customers say
Our propane furnace quit on a Sunday night in January and the house was at 58 by morning. They had a tech out before noon, found a failed igniter and a flame sensor that was filthy, and had heat back in about two hours. The price they quoted on the phone was the price I paid. No upsell, no drama.
Furnace was short-cycling and the propane bill had climbed all winter. The tech checked manifold pressure and found it set way too rich for our elevation. He cleaned the burner, reset the pressure and tested combustion. It has run steady since, and the cycles are noticeably shorter.
I manage a few rentals around Severance and Weld County, and I need a furnace tech who actually calls back. They diagnosed a bad control board at one property and a blower motor at another, both in the same week, and sent me the readings and photos afterward. That paperwork is worth as much as the repair.

(970) 1234567A flame sensor or igniter swap sits at the low end; a blower motor, gas valve or control board pushes toward the top. Emergency and after-hours calls add a trip charge. You get the full price before we start, and we do not bill for parts we did not install.
We do. Severance Furnace Repair Pros has worked on LP furnaces across Weld County since 2016, covering Carrier, Trane, Goodman, Rheem, Lennox, Bryant, York and American Standard models. Call (970) 1234567 and we will book a window, usually the same day for no-heat calls.
The most common causes we find are a dirty flame sensor, a failed igniter, a thermocouple that will not hold, or a gas valve that is not opening. At Severance's altitude, a furnace set up for low elevation can also run rich, soot the burner and trip the limit switch. Any of these will leave you with cold air. We test the ignition sequence in order and find the actual failure instead of swapping parts.
Yes. We staff the phone for emergency calls and keep common igniters, flame sensors, thermocouples, capacitors and control boards on the truck. Most after-hours no-heat calls in Severance, Windsor and Eaton get a tech the same night. If we cannot fix it on the spot, we will tell you what is wrong and get the part ordered first thing.
