AfterFurnace Replacement in Fresno, CA
Furnace replacement in Fresno typically costs between $4,500 and $9,500 installed, depending on furnace size, efficiency rating, and whether ductwork modifications are needed. Most replacements take one full day, and we provide a written price before any work begins. If your furnace is over 15 years old or needs repairs that exceed half its replacement cost, it’s time to have a serious conversation about replacing it. Call (559) 354-6878 and we’ll walk you through whether repair or replacement makes more sense for your home.
This page covers how furnace replacement works, what it costs in the Fresno market, and what makes our process different. If you’re still deciding between repair and replacement, our Heating & Furnace in Fresno page gives a broader look at both options.
At Brandt HVAC Co Fresno, we know inviting a contractor into your home is a trust decision before it’s a heating decision. That’s why every customer knows exactly who’s coming, what they’ll do, what it costs, and what happens if anything goes wrong. It’s the only way we’ve done business since 2003.
When You Need Furnace Replacement
Not every failing furnace needs to be replaced. Some problems, like a home heating system’s worn igniter or a failed capacitor, are straightforward repairs. But certain situations make replacement the smarter financial decision. Here’s what we tell Fresno homeowners to look for:
- Your furnace is 15 to 20 years old. Furnaces in the Central Valley work hard through cold winter nights, and by year 15 most are running at 70% efficiency or less. A new high-efficiency unit can cut heating bills noticeably from the first winter.
- Repair costs are stacking up. If you’ve spent $400 on a blower motor in November and $600 on a control board in December, you’re approaching the point where replacement beats repair. A good rule of thumb: if a single repair costs half or more of a new system’s price, replace it.
- Your heat exchanger is cracked. This is the one repair we won’t band-aid. A cracked heat exchanger can leak carbon monoxide into your living space. When we find one, we shut the furnace down and recommend replacement, not repair.
- Rooms heat unevenly or the furnace runs constantly. In older Fresno homes with original ductwork, an aging furnace often can’t push air evenly through the system. If some rooms are hot and others stay cold, the equipment may be undersized or failing.
- Your energy bills keep climbing. A furnace that’s losing efficiency will show up on your PG&E bill before it shows up anywhere else. If heating costs rise year over year without a rate change or colder weather, your furnace is working harder for less output.
- Strange smells or rumbling noises. A burning smell that won’t go away or a deep rumble when the blower kicks on can signal a heat exchanger failure or a motor on its way out. We inspect first and replace only when it’s the right call.
Our Furnace Replacement Process
Here’s exactly how a furnace replacement with Brandt HVAC Co Fresno works, from first call to final walkthrough. No ambiguity, no surprises.
- Call and describe what you’re experiencing. A live person answers at (559) 354-6878, no phone tree, no voicemail. We ask basic questions about your furnace’s age, brand, and the symptoms you’re seeing.
- We schedule a replacement estimate. Before anyone sets foot in your home, you’ll receive the technician’s name and photo by text or email. Our technicians are background-checked and identity-verified under the Threshold Verified standard, and every one of them wears a photo ID badge they’ll show at the door. If someone shows up you weren’t told to expect, that visit is on us.
- In-home assessment and measurements. The technician measures your home’s square footage, inspects existing ductwork, checks the gas line and electrical connections, and asks about your heating habits. This isn’t a drive-by quote: we size the system properly so you don’t end up with a furnace that’s too big or too small.
- Written price, before any work starts. You’ll get a written quote with the furnace model, efficiency rating, warranty terms, and total installed price. We don’t start anything until you’ve read it, asked every question you have, and signed off. The price you agree to is the price you pay.
- Removal and installation, usually in one day. Our crew removes the old unit, installs the new furnace, connects gas and electrical, verifies airflow, and tests the system for carbon monoxide and proper combustion. Most replacements are done by evening.
- Walkthrough and written guarantee. Before we leave, we show you how the new thermostat works, go over the system, and hand you a written guarantee. Every replacement is covered by the 365-Day Done Right Promise: if something isn’t right within a year, we return at no charge and make it right.
Furnace Replacement Pricing in Fresno
Here’s what furnace replacement actually costs in the Fresno area, based on equipment tier and home size. These are real ranges we quote, not national averages pulled from a website.
| Furnace Type | Efficiency (AFUE) | Typical Installed Cost (Fresno) |
|---|---|---|
| Entry-level single-stage (Goodman, Rheem) | 80% | $4,500 – $5,800 |
| Mid-range two-stage (Trane, Lennox) | 92 – 96% | $6,200 – $7,900 |
| High-efficiency variable-speed (Trane, Lennox) | 96 – 98% | $7,500 – $9,500 |
What moves the number up or down:
- Furnace size. A 2,000-square-foot Fresno home needs a bigger unit than a 900-square-foot condo. Size drives cost, but so does proper sizing: an undersized furnace will run constantly, and an oversized one will short-cycle and wear out early.
- Efficiency rating. An 80% AFUE furnace costs less upfront but wastes 20 cents of every heating dollar. A 96% unit costs more now and pays back through lower PG&E bills over its 15-to-20-year life.
- Ductwork condition. If your ducts are leaking or undersized, we’ll recommend sealing or modifying them. That adds cost but without it, even the best furnace won’t heat evenly.
- Permits and code requirements. Fresno requires permits for furnace replacement, and the cost is included in our written quote. No surprise line items.
Every estimate is free. Call (559) 354-6878 and we’ll give you an exact number for your home, in writing, before you decide anything.
Brands We Install and Why We Recommend What We Do
Brandt HVAC Co Fresno installs all major residential furnace brands. We’re happy to quote a Trane or Lennox system when a homeowner wants top-tier efficiency and a strong manufacturer warranty. We also install Goodman and Rheem for homeowners who want a solid, dependable furnace at a lower upfront cost.
Here’s our honest take: the installation matters more than the brand name on the cabinet. A mid-range furnace installed carefully, with proper sizing and sealed ductwork, will outperform a premium unit installed carelessly. That’s why we put more emphasis on measurements, airflow testing, and combustion verification than on upselling you to the most expensive model on the truck.
If you’re not sure which brand fits your budget and comfort priorities, tell us what you’re hoping to spend and we’ll show you options at that price point. No pressure, no upsell.
Why Fresno Homeowners Choose Brandt HVAC Co Fresno
Furnace replacement is a significant purchase, and we understand that the person paying for it wants to know exactly what they’re getting. Here’s what we deliver on every job, without exception:
- A written price before anything starts. Never a verbal estimate that changes later. You see the cost in writing and agree to it before we touch your furnace.
- A written guarantee with every installation. If the system fails or the installation has a problem within 365 days, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s in writing.
- Technicians you know before they arrive. Name, photo, and background verification are sent to you before every visit. At the door, they show photo ID. The Threshold Verified standard isn’t a marketing phrase, it’s the way we hire and the way we show up.
- A live person answers the phone 24/7. Furnace goes out on a cold January night at 2 a.m.? A real person picks up. No voicemail, no recorded menu, no “your call is important to us” while you sit on hold.
Brandt comes from an old word for firebrand, the glowing piece of wood that starts a fire. We chose the name because our work is about exactly that: keeping a home warm when it matters most.
FAQs – Furnace Replacement
How much does furnace replacement cost in Fresno?
Furnace replacement in Fresno typically costs $4,500 to $9,500 installed, with the final price depending on furnace size, efficiency rating, brand, and whether ductwork needs modification.

Is it cheaper to repair or replace my furnace?
If your furnace is under 12 years old and the repair costs less than half the price of a new system, repair is usually the cheaper short-term option. If the furnace is over 15 years old, has a cracked heat exchanger, or has already needed multiple repairs in one season, replacement typically saves money over the next five years. We’ll give you an honest recommendation either way, with numbers to back it up.

In most cases, yes, if we have the right unit in stock or can source it locally in Fresno by morning.
