What we handle
From a quick fix to a full replacement.
Most furnace calls are repairs that take an hour. Some are end-of-life replacements. We'll tell you honestly which one you've got — and we don't mark up parts.
Furnace replacement
Standard or high-efficiency models. We size them properly and re-pipe the gas line and venting to current code.
Annual tune-ups
Clean the burners, test combustion, check the heat exchanger, replace the filter. Cheaper than a no-heat call in February.
Indoor air quality add-ons
Whole-house humidifiers, UV lights, high-MERV media filters — installed alongside the furnace if you want better air.
How it works
From phone call to walkthrough — done right.
1. Diagnostic visit
Flat-rate diagnostic fee — applied toward the repair if you go ahead. We test, explain, and give you a written estimate before any work starts.
2. Repair or replace decision
We'll tell you whether it's worth fixing or whether you're throwing money at a 20-year-old unit. Honest math — no scare tactics.
3. Clean, code-compliant work
Gas piping, venting, and flue per code. We pull permits when required and pressure-test gas joints with soap and a manometer.
4. Tested and walked through
Combustion analyzer test on every install, then we walk you through the thermostat and filter schedule before we leave.
Why Competitive
We don't promise quality. We deliver it.
We size it for your house, not the catalog
Manual J load calc on every install — most contractors skip it. Wrong size = short cycling, comfort issues, and a lot of wasted fuel.
Mass Save rebates handled for you
We're a registered Mass Save partner. Generous rebates on qualifying heat pumps and high-efficiency boilers — we file the paperwork.
Master Plumber on every install
Licensed Master Plumber (MA #MP17629) on every install — not a sales rep, not a sub.
Clean, labeled, serviceable
Our installs are diagrammed, labeled, and tidy. The next tech who walks in (even if it's not us) can service the system without guessing.
FAQ
Common questions about furnace repair & replacement.
How quickly can you get to a no-heat call?
Same day during heating season. Call (508) 944-7623 — we answer 24/7 and we'll tell you up front whether we can be there in 2 hours or 24.
Should I repair my old furnace or replace it?
Rule of thumb: if the repair is over half the cost of a new unit AND the furnace is 15+ years old, replacement usually wins on running cost. We'll run the numbers with you.
Do you charge a diagnostic fee?
Yes — a flat rate. It's applied toward the repair if you go ahead with the work the same day. No mystery charges.
What brands do you install?
Trane, Carrier, Goodman, Bryant, Rheem. We stock parts for all the common brands and we're brand-agnostic — we recommend what fits your house and budget.
