Furnace Repair Service in Portland, ME
A repair call means something specific is wrong and we need to find it before we can fix it. That's not always a fast process — some faults hide behind other symptoms. We diagnose first, explain what we found, then get your approval before we touch any parts.

When to Call

- Burner ignites then shuts off after a few seconds

How It Works
Our Process for Furnace Repair Service
- 1
Intake call
We ask what the furnace is doing, how old it is, and what fuel type. That shapes what tools and parts we bring on the first visit.
- 2
Diagnostic inspection
We run the furnace through a full cycle, check error codes, test the igniter, flame sensor, pressure switches, and heat exchanger. We look at the actual problem, not just the obvious symptom.
- 3
Findings walkthrough
We tell you what's wrong, what caused it, and what we recommend. If we find a secondary issue, we flag it separately so you can decide.
- 4
Repair approval
You approve the work before we start. If we need a part we don't have on the truck, we tell you lead time honestly before you commit.
- 5
Repair and test
We make the fix, then run the furnace through multiple cycles to confirm it's operating correctly before we leave.
- 6
Documentation
We leave you a written summary of what was found, what was done, and any other items worth watching in coming months.
What's included
- Full diagnostic inspection of the furnace and its controls
- Labor to repair the identified fault on that visit
- Parts needed for the repair, sourced same-day when possible
- Post-repair operational test through multiple heat cycles
- Written summary of the repair and any observed secondary issues
What's not included
- Repairs to ductwork, flue pipe, or gas line — those are separate scopes
- Parts that require a factory order — we'll quote lead time and a return visit separately
- Cleaning or tune-up services unless specifically added to the work order
Real Situations
Common Scenarios in Portland
A homeowner on Munjoy Hill has a 1990s gas furnace that ignites for a few seconds and then shuts off repeatedly.
That pattern usually points to a dirty or failed flame sensor, but it can also mean a cracked heat exchanger tripping a limit switch. We test both before calling it. If it's the sensor, we clean or replace it that visit. If it's the heat exchanger, we walk you through what that means for the furnace's future.
A family in South Portland notices their forced-air furnace runs constantly but the house feels cold and drafty near the floor.
We check the furnace output temperature against what's actually reaching the registers. The gap usually lives in duct leakage or a failing blower motor. We identify the source, quote the fix, and let you decide how to proceed.
An older Cape Cod in Deering has a furnace making a loud metal-on-metal scraping sound when it starts.
That sound is almost always a blower wheel that's come loose or a failing blower motor bearing. We pull the blower assembly, inspect it, and replace what's worn. We don't replace parts that don't need it.
Portland Context
Why this matters in Portland
Portland's winters are long and genuinely cold, and most homes here run their furnaces hard from October through April. A lot of the housing stock in the city — particularly in the West End, Deering, and the neighborhoods east of 295 — has older heating systems that were installed in the 80s or 90s and are now working past their designed lifespan. That age profile means repair calls here tend to involve parts that aren't always stocked locally, which is something we account for when we schedule.
Straight Talk
About pricing & scope
Repair costs vary based on what part failed, whether we have it on the truck, and how accessible the component is inside your particular unit. Older furnaces sometimes reveal a second problem once the first is fixed — we'll tell you if that happens rather than quietly adding it to the bill. You approve every scope change before we proceed.
