AfterHow Much Does HVAC Cost in Boston?
Most HVAC repairs in Boston run between $175 and $825, with AC repairs landing at $175 – $765 and furnace repairs at $175 – $825. A seasonal tune-up is far less, at $95 – $235, while full AC installation runs $4,130 – $8,850 depending on system size and the age of your home’s ductwork. The single biggest factor in what you’ll pay is what’s actually broken, not which company you call.
Here’s what we see across Boston every week: a furnace that won’t fire on a January morning is usually a $175 – $400 fix, while a failed compressor in August pushes toward the top of the AC range. We give you a written price before any work starts, so you’re never guessing at the number while a technician stands in your basement.
HVAC Cost Breakdown (2026)
These are real Boston-market ranges, parts and labor included. Your exact price depends on the system and the diagnosis, but this is the ballpark you should expect to see.
| Service | Typical Boston Range | What It Covers |
|---|---|---|
| AC Repair | $175 – $765 | Diagnostics, parts, and labor for cooling problems |
| Furnace Repair | $175 – $825 | Igniters, blowers, control boards, and heat-related fixes |
| AC Installation | $4,130 – $8,850 | New condenser, coil, line set, and startup |
| Tune-Up / Maintenance | $95 – $235 | Cleaning, inspection, and performance check |
To give you a sense of where your repair might land inside those ranges: a furnace igniter replacement typically sits near the lower end, a blower motor replacement lands in the middle, and a full heat exchanger issue or compressor failure pushes toward the top. On the cooling side, a refrigerant recharge (that means refilling the fluid that moves heat out of your home) and a capacitor swap are common mid-range jobs, while compressor and coil work cost more.
Two things push the price up no matter what’s wrong. First, age and access: a 1920s triple-decker in Dorchester with a furnace squeezed into a basement corner takes longer to work on than a newer build in the Seaport. Second, whether parts are in stock or need ordering. What pushes it down is catching the problem early. A $95 tune-up that finds a worn capacitor often saves you from a $700 emergency call three weeks later.
What Affects HVAC Pricing in Boston
- What’s actually broken. A thermostat or sensor is a quick, low-cost fix. A compressor or heat exchanger is at the top of the range. The diagnosis drives the number more than anything else.
- System age and brand. We service all major residential brands – Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard – but parts availability and pricing vary by brand and by how old the unit is.
- Boston housing stock. Old triple-deckers in Dorchester and Roxbury, tight basements in South Boston, and crawlspaces in older suburban homes all make the work slower. Tight access adds labor time, and labor is part of every quote.
- New England weather load. Boston winters put heavy demand on furnaces and summers strain AC systems. A system that’s been running hard for a decade often needs more than a single part replaced.
- Emergency vs. scheduled timing. A no-heat call at 11 p.m. in February often involves a higher labor rate than the same repair booked on a Tuesday afternoon. Scheduling ahead usually costs less.
- Ductwork condition. Leaky or undersized ducts force your system to work harder. If ducts need attention during an installation, that’s added to the job.
One more factor worth naming: who’s coming into your home. When you’re comparing quotes, you’re not just comparing dollars. You’re comparing whether you’ll know the technician’s name and see a photo and ID badge before they knock. That certainty is part of what Brandt HVAC is built around, and we’ll come back to it.
How to Save on HVAC
You don’t have to pay the top of the range. A few habits keep real money in your pocket:
- Book a tune-up before the season turns. A $95 – $235 tune-up in fall or spring catches small problems before they become emergency repairs. This is the single best return on a few dollars you’ll get on your HVAC.
- Change your filter. A clogged filter makes your furnace and AC work harder and shortens their life. It’s the cheapest maintenance there is.
- Fix it early, not late. A $200 igniter today can become an $800 bill if you wait and let the problem spread.
- Get a written price before work starts. Every Brandt HVAC job begins with a written price you agree to first. No moving numbers, no surprise line items.
- Ask about the guarantee. Every repair we do comes with a written guarantee and the 365-Day Done Right Promise. If a repair fails within 365 days, we return at no charge. That’s a free second visit, not a new invoice.

FAQs – HVAC Cost
How much does a furnace repair cost in Boston?
Furnace repair in Boston typically runs $175 – $825, parts and labor included. Simple fixes like an igniter or sensor sit near the low end, while blower motors, control boards, and heat exchanger work push toward the top. Call (984) 538-9003 for an exact quote, free of charge.
How much does AC repair cost in Boston?
AC repair in Boston usually costs $175 – $765. A capacitor or refrigerant recharge is a mid-range job, while compressor or coil problems cost more. If your AC quit during a July heat wave, call (984) 538-9003 and we’ll give you a written price before anything starts.
Is it cheaper to repair or replace my HVAC system?
Repair is almost always cheaper up front: a typical repair is $175 – $825, while new AC installation runs $4,130 – $8,850. The general rule is that if the repair costs more than a third of a new system and the unit is near the end of its life, replacement makes more financial sense. We’ll give you both numbers in writing so the decision is yours. Call (984) 538-9003 for a free estimate.
Can you come today if my heat or AC stops working?
In most cases, yes. We answer the phone with a live person 24 hours a day, 7 days a week, nights, weekends, and holidays, so you’re never stuck in a voicemail queue. Call (984) 538-9003 and we’ll schedule the soonest available visit and give you a clear price range before we arrive.
What does a Brandt HVAC guarantee actually cover?

That covers a free second visit, parts and labor on the failed repair. It’s written down before we leave, not just promised on the phone. Call (984) 538-9003 to schedule and we’ll walk you through exactly what’s covered.
One Thing We Ask You to Compare
Most HVAC companies compete on the lowest number. We don’t think that’s the whole story. When someone’s coming into your home, the question isn’t only “what will it cost” but “who is this, and how do I know.” That’s why every Brandt HVAC technician is background-checked and identity-verified through our Threshold Verified standard, and why we send you their name and photo before the visit. When they arrive, they show a photo ID badge at the door. If anyone shows up who you weren’t told to expect, that visit is on us and we make it right.
Brandt comes from an old word for a firebrand, which feels right for the work of keeping a home warm. We’ve been part of the Threshold Group family since 2003, and each location is independently owned and operated. Our phones are staffed by a live person around the clock, and every job starts with a written price and ends with a written guarantee. When a repair isn’t done right, the 365-Day Done Right Promise means we come back and fix it, free.
Devin Marlowe leads our team, and the standard he set is simple: you should know exactly who’s at your door, exactly what it costs, and exactly what happens if something goes wrong.
