AfterHow Much Does Furnace Replacement Cost in West Palm Beach?
Furnace replacement in West Palm Beach typically runs $3,500 to $7,500 for a complete system, including equipment and installation. Most homeowners pay around $4,500 to $5,500 for a mid-efficiency gas furnace sized for a standard Florida single-family home. Your exact price depends on the furnace’s efficiency rating, the brand, and whether your ductwork or electrical panel needs updates during the job.
Below, we break down exactly where those dollars go, what pushes the price toward the top or bottom of that range, and how to get a firm written number before anyone starts work.
Key Takeaways
- Complete furnace replacement in West Palm Beach: $3,500 to $7,500 installed.
- Mid-range, most common install: $4,500 to $5,500 for a 60,000 to 80,000 BTU gas furnace from a name-brand manufacturer.
- High-efficiency models (90%+ AFUE): add $1,500 to $2,500 over a standard 80% unit.
- Ductwork replacement or modification: adds $1,500 to $4,000, depending on the size of the home.

Furnace Replacement Cost Breakdown (2026)
Here’s the line-by-line breakdown for the West Palm Beach market. These are real numbers we quote from, not national averages that ignore South Florida’s climate and housing stock.
| Cost Component | Typical Range (West Palm Beach) | Notes |
|---|---|---|
| Furnace unit (80% AFUE, 60,000-80,000 BTU) | $1,200 – $2,200 | Goodman, Rheem, Carrier, Trane entry-level to mid-tier units |
| High-efficiency unit (90-96% AFUE) | $2,200 – $3,800 | Carrier, Lennox, Trane, Bryant two-stage or modulating models |
| Labor and installation | $1,500 – $2,800 | Includes removal of old furnace, flue connections, gas line hookup, electrical, start-up testing |
| Permit and inspection | $75 – $250 | City of West Palm Beach or Palm Beach County mechanical permit |
| Smart thermostat (optional) | $150 – $350 | Ecobee, Honeywell, or Nest upgrade at time of install |
| Ductwork modification (if needed) | $1,500 – $4,000 | Often needed in older West Palm Beach homes with corroded or poorly sealed ducts |
| Electrical panel upgrade (if needed) | $800 – $2,500 | Required if existing panel lacks capacity or is outdated |
That puts a straightforward furnace swap in the $3,500 to $4,500 range. Add a high-efficiency unit and a thermostat, and you’re at $5,500 to $7,000. If the ductwork needs real work or the panel is outdated, the total can land between $7,000 and $9,500.
One thing worth knowing about West Palm Beach specifically: many homes here were built in the 1960s through the 1980s, when air conditioning was the priority and heating was almost an afterthought. We regularly find undersized gas lines and corroded flue pipes in ranch houses in the South End and neighborhoods near Southern Boulevard. Those are local conditions that national cost calculators don’t account for, and they’re exactly why you want a contractor who has actually cut open furnaces in this city, not one reading from a franchise playbook.
What Affects Furnace Replacement Pricing in West Palm Beach
Every factor below moves the final number. Here’s what we look at when we quote a job.
- Furnace efficiency rating (AFUE). An 80% AFUE furnace is the price floor, typically $1,200 to $2,200 for the unit alone. A 96% AFUE two-stage furnace from Trane or Lennox runs $2,800 to $3,800 for the equipment. You’ll pay more up front, but a high-efficiency unit can cut your gas bill noticeably during the short but real West Palm Beach heating season, which runs from roughly December through February.
- BTU sizing. A 45,000 BTU furnace for a small condo in the Northwood area costs less than a 100,000 BTU unit for a 3,000-square-foot house in Ibis or Bay Hill Estates. We size the furnace to a Manual J load calculation, not a rule of thumb. An oversized furnace cycles too often, and that shows up as humidity problems and higher bills.
- Existing ductwork condition. Salt air is hard on metal. Ductwork in homes near the Intracoastal or within a mile or two of the ocean often has rust at the seams and leaks at the supply boots. If we can seal and reuse it, you save. If it’s too far gone and we need to replace runs, plan for the $1,500 to $4,000 add-on.
- Flue and venting requirements. Older West Palm Beach homes often have a standard metal flue pipe, which works fine with an 80% furnace. High-efficiency condensing furnaces need PVC venting instead. Running new PVC through a home that wasn’t built for it adds $300 to $800, depending on distance to an exterior wall.
- Gas line capacity. This is the one that surprises people. Many older homes here have 1/2-inch gas lines sized for a small furnace from 30 years ago. A modern unit may need 3/4-inch or even 1-inch supply. Upgrading the gas line adds $400 to $1,200 when the line runs through an accessible attic or crawl space. If it’s buried under a slab, that number climbs.
- Permit and inspection fees. The City of West Palm Beach requires a mechanical permit for furnace replacement. Fees run roughly $75 to $250 depending on the scope. Some contractors skip permits to keep the price low. We don’t, and you shouldn’t accept that trade. A permitted install means a county inspector verifies the gas connections, venting, and electrical work after we finish.
Because every home presents a different combination of these factors, a real quote requires a visit. The good news: we give you that written price before any work starts, and Brandt HVAC doesn’t play the game of a low ballpark number that grows after the old furnace is on the truck.
Furnace Replacement vs. Furnace Repair: Which Makes Sense?
Furnace repair in the West Palm Beach market runs $150 to $700 for most jobs. The replacement decision usually comes down to three questions.
How old is the unit? Furnaces in South Florida last 15 to 20 years on average. If yours is past that mark and needs a repair over $500, replacement starts to make more sense than pouring money into a system that’s already lived its design life.
What’s the repair? A failed blower motor ($350 to $650) on a 12-year-old furnace is usually worth fixing. A cracked heat exchanger (which can run $800 to $1,500 to replace, when a replacement part is even available) on a 18-year-old furnace is a signal to replace. A cracked heat exchanger is also a safety issue, since it can allow carbon monoxide into the home’s air supply.
Efficiency gap. If you’re running an old 60% AFUE furnace or – worse – electric resistance heat, the new 80% or 96% unit will pay back part of its cost in lower gas or electric bills every winter.
The short version: if the repair is under half the cost of replacement and the unit is under 10 years old, repair it. If either condition fails, get a replacement quote. We’ll give you both numbers in writing and let you decide without pressure.
Step-by-Step: How Furnace Replacement Works With Us
Here’s the exact process, so you know what to expect from the first call to the final inspection.
- You call (728) 220-0996. A live person answers. No phone tree, no voicemail queue. That’s true at 2 p.m. and at 2 a.m. We take your address, the furnace’s age and brand if you know it, and schedule a visit at a time that works for you.
- You get your technician’s name and photo before arrival. Every Brandt HVAC technician is background-checked and identity-verified through the Threshold Verified standard. Before the visit, we send you the name and photo of the person who will walk up your driveway. When they arrive, they’ll wear a uniform and show a photo ID badge at the door. If the person at your door is not the person we told you to expect, that visit is on us. We make it right, no charge and no questions.
- The technician does a full assessment. We measure the home, inspect the ductwork, check gas line sizing and capacity, look at the electrical panel, and test the existing flue. This takes 45 to 90 minutes. Every measurement matters because it feeds the load calculation that determines the right furnace size.
- You get a written price before any work starts. No exceptions. The quote lists the furnace model, the labor, the permit fee, the haul-away of the old unit, and any ductwork, gas line, or electrical work. You see and approve the total. If you don’t approve, we don’t order a single part.
- Installation day. Most furnaces in West Palm Beach homes install in one day. The crew protects the work areas, removes the old furnace, sets the new one, connects gas, electrical, and venting, tests the system, and walks you through the thermostat. Work is guaranteed in writing, and the guarantee covers parts and labor for 365 days. If the repair or installation fails within that year, we return and make it right at no charge under the 365-Day Done Right Promise.
- County inspection. The mechanical permit requires a final inspection by a county inspector. We schedule it, meet the inspector on site, and fix anything the inspector flags – again at no additional cost to you. You shouldn’t have to chase an inspector. We do that.
That’s the whole process. Written price up front, verified person at the door, and a 365-day guarantee on the work in writing. We named the company after the old word for a firebrand – Brandt – because the work of keeping a home warm is exactly that.
How to Save on Furnace Replacement
Furnace replacement is a five-figure purchase in some parts of the country. In West Palm Beach, it’s usually half that, but nobody wants to spend a dollar more than necessary. Here’s how to keep the job lean without cutting corners that cost you later.
- Replace before it fails. Emergency replacements cost more in overtime rates and rushed equipment orders. If your furnace is 15-plus years old, getting a quote in September or October is cheaper than calling in January when the cold snap hits and every contractor in Palm Beach County is booked solid.
- Right-size, don’t oversize. A furnace that’s too big costs more to buy, cycles too often, and wears out faster. A proper Manual J load calculation keeps you from paying for BTUs you don’t need.
- Keep the ductwork if it’s sound. If your ducts hold air and just need sealing, that’s a $300 to $700 job instead of a $2,000 to $4,000 replacement. We’ll tell you honestly which one you need, because the written quote explains exactly what work we’re doing and why.
- Look at the lifetime cost, not just the sticker. The cheapest 80% furnace will work. A mid-efficiency 92% unit costs $800 to $1,500 more but can cut heating costs 20-30%. Over 15 years in a house that sees modest winter use, that math doesn’t always favor the premium unit. We’ll show you both and let you decide – without steering you toward the pricier one for the sake of our invoice.

Why West Palm Beach Furnace Pricing Differs From the National Average
National replacement guides often list $5,000 to $8,000 as the “average” furnace replacement cost. West Palm Beach sits at the lower end of that, for reasons specific to this city.
Florida heating loads are small. A cold winter night in West Palm Beach might drop into the 40s, but the furnace only runs a couple of hours a day, and only for about three months. That means we install smaller furnaces – 45,000 to 80,000 BTU is standard here, versus 80,000 to 120,000 in northern states. Smaller equipment costs less.
The flip side: salt air and humidity punish ductwork and venting here in ways you don’t see in Atlanta or Charlotte. We routinely quote ductwork sealing or replacement on West Palm Beach furnace jobs at rates that national averages don’t capture. And because homes here prioritize AC, many have air handlers in closets or attics where a furnace retrofit takes extra labor to fit the gas and venting into space not designed for it.
Our Furnace Replacement in West Palm Beach page covers the installation process in detail, including the local permit requirements and what to expect from the county inspection.
FAQs – Furnace Replacement Cost
How much does it cost to replace a furnace in West Palm Beach?
Furnace replacement in West Palm Beach runs $3,500 to $7,500 for the complete job, with most homeowners paying $4,500 to $5,500. The range covers equipment, labor, permits, and haul-away of the old unit. Call (728) 220-0996 for a written, free estimate that locks in your exact price.
Is it cheaper to repair or replace a furnace?
Furnace repair in West Palm Beach runs $150 to $700 for most jobs, while replacement runs $3,500 to $7,500. If the repair costs less than half the replacement price and the furnace is under 10 years old, repair usually makes sense. If not, replacement is the smarter money. We’ll quote both options in writing so you can decide with the real numbers in front of you.
How long does furnace replacement take?
Most furnace replacements in West Palm Beach homes take one full workday, typically 6 to 8 hours. Jobs that include ductwork replacement or electrical panel upgrades can run two days. We’ll tell you the expected timeline in the written quote, before any work starts.
How much is a high-efficiency furnace compared to a standard one?
A high-efficiency furnace (90% to 96% AFUE) adds $1,500 to $2,500 over a standard 80% AFUE unit. For a typical West Palm Beach home, that means $4,500 to $5,500 for a standard furnace versus $5,500 to $7,000 for high-efficiency, all in. We’ll show you the payback math for both, based on your actual gas usage.
Can I get a furnace replaced the same week I call?
In most cases, yes. Peak heating season in West Palm Beach runs from late December through February, and during those months same-week scheduling can be tight. Call (728) 220-0996 and we’ll give you a real answer on scheduling – not a promise we can’t keep – and the estimate is free.
Do I need a permit to replace a furnace in West Palm Beach?
Yes. The City of West Palm Beach requires a mechanical permit for furnace replacement, and county inspection verifies the gas line, venting, and electrical connections. Permit fees run $75 to $250. Any contractor who suggests skipping the permit is cutting a corner that can leave you with unsafe work and no legal recourse. We handle the permit and the inspection on every job, and that’s reflected in the written price.
