Furnace service
Heat back on inside two hours. Tune-ups that catch problems in October, not January.
Gas, oil, propane — we service every common residential setup in MetroWest. Annual tune-ups in October surface the small problems while parts are still in stock and we can still get on the schedule. When something fails mid-winter, business-hours no-heat calls get a tech inside two hours.
Pricing
What it costs.
Typical residential furnace pricing in MetroWest. Diagnostic fee comes off the repair total if we do the work the same visit.
-
Annual furnace tune-up
Full inspection per the checklist below. Combustion analysis, safety controls, blower performance, draft test. Book in September for October scheduling.
$189 -
No-heat diagnostic
On-site diagnosis, system test, written findings. Applied in full toward any repair we make the same day. Business hours only — after-hours adds $95 dispatch.
$95 -
Hot surface ignitor or flame sensor
The two most common no-heat failures on modern gas furnaces. Replacement, ignition cycle test, parts on the truck.
$200–$350 -
Inducer motor replacement
The motor that pulls exhaust through the heat exchanger. Replacement, draft pressure verified, full heat cycle confirmed.
$450–$750 -
Blower motor replacement
PSC motors land at the low end; variable-speed ECM motors run higher. Includes wheel balance and amp draw test.
$600–$1,200 -
Gas valve replacement
Manifold pressure verified, gas leak check at every fitting, full burn cycle test.
$500–$850 -
Full furnace replacement (80% AFUE)
Builder-grade 80% efficient gas furnace, professionally sized, code-compliant venting, permits pulled. Single-zone residential.
$4,500–$6,500 -
Full furnace replacement (96% AFUE condensing)
Two-stage or modulating 96%+ efficient gas furnace, condensate kit, PVC venting, permits pulled. Single-zone residential.
$6,500–$9,500
Oil burner service follows similar pricing — nozzle, electrodes, and pump service on tune-ups, $350–$750 typical on common repairs. Mass Save offers a $5,000 rebate when replacing oil with a heat pump system; we'll quote both side-by-side if you're weighing the decision. Wisetack financing available on any repair over $300.

What we check
Every tune-up covers:
- Combustion analysis with calibrated analyzer (CO, O₂, stack temp)
- Heat exchanger inspection with mirror or borescope
- Burner cleaning and ignition test
- Hot surface ignitor or flame sensor cleaning
- Gas valve manifold pressure to manufacturer spec
- Draft pressure and venting integrity
- All safety controls: rollout, limit, pressure switches
- Inducer and blower motor amp draw
- Blower wheel and air filter
- Thermostat calibration and low-voltage wiring
- Static pressure across the air handler
- Condensate trap and drain (on 90%+ systems)
Questions
Worth asking before you book.
When should I schedule a tune-up?
September or October. By November the schedule fills up with the first cold-snap no-heat calls, and the goal of a tune-up is to find problems before the system has to work hard. A November tune-up is better than no tune-up — but September beats both.
Do you service oil furnaces and boilers?
Yes — oil-fired warm-air furnaces and oil boilers both. Nozzle, electrodes, pump pressure, and combustion analysis are part of every oil tune-up. We don't currently install new oil-fired equipment — most oil customers in MetroWest are converting to heat pumps with the Mass Save rebates.
My furnace is 20 years old. Repair or replace?
The honest answer depends on which part failed. A $300 ignitor on a 20-year-old furnace is still worth it. A $1,500 heat exchanger or inducer probably isn't — at that age the next failure is around the corner. We'll quote the repair, quote the replacement, and show you the five-year cost on both.
What's the difference between 80% and 96% efficient?
80% AFUE means 20% of the fuel you buy goes out the chimney as exhaust heat. 96% AFUE condenses the exhaust to capture that heat — annual fuel savings of 15–20% for most MetroWest homes, plus PVC venting (no chimney liner needed). 96% costs about $2,000–$3,000 more upfront and typically pays back in 6–8 years on a Mass gas bill.
Do you handle the permit?
Always. New furnace installs in MA require a gas permit and a building permit in most towns. We pull both, schedule the inspections, and meet the inspector on-site. You don't touch paperwork.
Is a Comfort Club membership worth it?
If you're going to do a tune-up every year anyway: yes. Comfort Club is $189/year and covers both your furnace tune-up in October and your AC tune-up in May, plus 15% off any repairs between visits. Most members break even the first time we catch a $400 part going bad before it fails on a 10-degree night.
What's the warranty on a new furnace?
Carrier residential furnaces carry a 10-year parts warranty when registered (we register every install for you). Heat exchangers are typically 20 years or lifetime on the higher-efficiency models. Our labor warranty is 2 years on full installs, longer on Comfort Club members.
