Furnace Repair in Jacksonville, FL

Furnace Repair in Jacksonville, FL

Furnace repair in Jacksonville typically costs between $150 and $650 depending on the part that failed, and most repairs can be completed the same day you call. When your heat stops working on a cold January night, you need someone who will answer the phone, tell you exactly who is coming, and give you a written price before any work begins. That is how Brandt HVAC Co Jacksonville operates, and it is the standard Devin Marlowe has held this company to since day one.

Jacksonville’s climate is unique for Florida. We get stretches of genuinely cold weather, especially in neighborhoods like Riverside, Arlington, and Mandarin, where older homes often run furnaces hard from December through February. Those furnaces sit idle for months at a stretch, then get asked to fire up during a cold snap. That pattern, long idle periods followed by sudden demand, is exactly what causes many of the failures we see. A furnace that ran fine in March has had eight months for a blower bearing to seize, a pressure switch to rust, or a heat exchanger to develop a hairline crack. So if you flipped your thermostat to heat and nothing happened, or you heard a bang, or you smell something odd coming from the vents, you are not alone. This is the busiest time for furnace work in Jacksonville, and we are ready for it.

We are part of the Threshold Group family of home-service companies, established in 2003. Each location is independently owned and operated, and our Jacksonville location is led by Devin Marlowe. Our home service philosophy is straightforward: a live person answers the phone 24 hours a day, a written price comes before any work starts, and every technician is background-checked and introduced to you by name and photo before they ever ring your doorbell.

Furnace repair is a core part of our broader Heating & Furnace service. Whether your system is a Trane, a Rheem, or something else entirely, the approach is the same: diagnose it properly, explain it in plain language, and fix it right the first time. If a repair ever fails within the guarantee period, a return visit is free under our 365-Day Done Right Promise. That is not marketing language. It is the written guarantee on every repair we do.

When You Need Furnace Repair

Here are the most common reasons Jacksonville homeowners call us. If any of these sound familiar, we can usually get a technician to you the same day:

• The furnace is blowing cold air. This often points to a failed igniter, a tripped flame sensor, or a gas valve that is not opening. In older Jacksonville homes with original ductwork, it can also mean a blower motor has stopped spinning while the burner still fires, which is a problem that needs immediate attention.
• The system short cycles. If your furnace kicks on for two or three minutes, shuts off, then restarts a few minutes later, you are likely dealing with a dirty flame sensor or an overheating limit switch. Short cycling wastes gas and wears out components faster.
• You hear banging, rattling, or screeching. A loud bang at startup is often delayed ignition, which can be dangerous. A high-pitched screech usually means a failing blower motor bearing. Neither is a noise you should live with.
• There is a burning smell that will not go away. A quick whiff of dust burning off when the season first starts is normal. A persistent smell, especially one that smells like rotten eggs, is not. Call us immediately. Natural gas is odorized with mercaptan so you can smell a leak, and a gas leak means turning off the furnace and calling a professional today.
• Your energy bill jumped for no obvious reason. A furnace that is losing efficiency will run longer to hit the same temperature. That usually means a dirty burner, a failing heat exchanger, or a blower that needs attention. Even a 15% drop in efficiency shows up on your monthly bill.
• The pilot light will not stay lit, or the furnace will not ignite at all. This could be a thermocouple, a control board, or an igniter that has simply worn out. Modern furnaces use hot surface igniters, and they do fail; in our experience, most igniter replacements happen between years 8 and 12 of a furnace’s life.

If you are in San Marco, Ortega, or anywhere else in Duval County and you are experiencing any of these issues, call us at (904) 456-0205. We will tell you what we think is going on, give you a straight answer about whether it is worth repairing, and get someone out to you fast.

Our Furnace Repair Process

Every furnace repair we do follows the same process. It exists so you are never guessing, never waiting on a callback, and never surprised by a bill:

1. You call, a live person answers. No phone tree, no “press 2 for service,” no voicemail that gets returned hours later. Whether it is 2 in the afternoon or 2 in the morning, a real person picks up the phone at Brandt HVAC Co Jacksonville.
2. We schedule a technician and tell you who is coming. Before the appointment, we send you the technician’s name and photo. When they arrive, they wear a Brandt HVAC uniform and show you a photo ID badge at the door. This is part of the Threshold Verified standard we follow on every single visit. If someone shows up who you were not told to expect, that visit is on us and we make it right.
3. The technician diagnoses the issue and explains it in plain language. We show you what is wrong before we quote a single dollar. You will hear the real trade term, like “flame sensor” or “limit switch,” and then we explain exactly what that part does and why it failed. You should never feel talked down to or confused.
4. You get a written price, and no work starts until you approve it. This is non-negotiable at our company. The price on the sheet is the price you pay. Parts, labor, everything. No surprises when the invoice comes.
5. We make the repair, test the system, and walk you through what we did. After the work is done, we run the furnace through a full cycle and verify the repair with you standing there if you would like. Then we explain the written guarantee, which covers the repair for 365 days.
6. If the repair fails, we come back free. That is the 365-Day Done Right Promise in action. No argument, no additional charge, no fine print. If it was not done right, we make it right.

Furnace Repair Pricing in Jacksonville

Here is what we typically see in the Jacksonville market. These are real ranges from actual service calls, not national averages pulled from a website, but we want to set realistic expectations today. Every home is different, and your exact price comes in writing before any work begins:

Repair Type	Typical Cost Range	What Affects Price
Flame sensor cleaning or replacement	$90 – $180	Part quality, furnace brand (Trane and Lennox parts can run slightly higher)
Hot surface igniter replacement	$150 – $300	Igniter type, furnace age and accessibility
Limit switch replacement	$140 – $280	Location of the switch, whether the blower assembly must be removed
Pressure switch replacement	$160 – $320	Specific switch calibration, venting setup in older homes
Blower motor replacement	$350 – $650	Motor horsepower, ECM vs. standard motor, furnace brand (Goodman and Rheem replacement motors are generally mid-range)
Gas valve replacement	$250 – $500	Valve type, propane vs. natural gas configuration
Control board replacement	$300 – $550	Board complexity, whether it is an OEM or aftermarket part

What affects your final price: older furnaces with discontinued parts cost more to repair because the parts are harder to source. Homes in historic districts like Riverside and Avondale often have tight mechanical closets or crawlspace installations, which can add labor time. And the brand matters. A Trane or Lennox control board costs more than a comparable Rheem or Goodman board, simply because of how the manufacturers price their OEM components.

We give free estimates on every repair, and the estimate is always in writing before work starts. Call (904) 456-0205 and we will get you an exact price for your specific furnace and situation.

Furnace Brands We Service in Jacksonville

Brandt HVAC Co Jacksonville works on every major residential furnace brand. We carry or can quickly source parts for Trane, Lennox, Goodman, and Rheem, along with the rest of the major manufacturers. One thing we have learned from years in this trade: the brand matters less than the quality of the installation and the maintenance it has received. We have seen 20-year-old Rheems running like new and 6-year-old high-end Tranes with cracked heat exchangers. What matters is that the technician knows how to diagnose the specific system in front of them, not just the brand name on the cabinet.

If you are looking for ongoing care and prevention rather than a one-time repair, we also offer Heating & Furnace maintenance plans that keep your system from failing in the first place. A furnace that is tuned up before the Jacksonville cold season starts will almost never surprise you on the coldest night of the year.

Why Jacksonville Homeowners Choose Brandt HVAC Co Jacksonville

We know you have options for furnace repair in Jacksonville. Here is what we think actually matters when you are choosing who to let through your door:

• You know exactly who is coming. Every Brandt HVAC technician is background-checked and identity-verified under the Threshold Verified standard. Before your appointment, we send you the technician’s name and photo. They arrive in uniform, and they show you a photo ID badge before they step inside. If you are home alone, or you have young kids, or you just do not like the idea of opening your door to a stranger, this is the standard we built our company around.
• The price is written down before any work starts. We do not do verbal quotes. You get a written price, you read it, you agree to it, and only then does anything happen. The number on that sheet is the number you pay.
• The guarantee is also in writing. Every repair includes a written guarantee, and if the repair fails within the guarantee period, we return at no charge. This is covered by our 365-Day Done Right Promise, and it has been part of how we operate since 2003.
• A live person answers the phone, always. Furnace problems do not happen on a schedule. They happen at 9 PM on a Tuesday in February. When you call us then, a person picks up. Not a machine, not a callback queue. A person who can start solving your problem immediately.

The name Brandt comes from an old word for a firebrand, a fitting name for the work of keeping a home warm. That origin story is a nice piece of history. The real reason people choose us is simpler: we tell the truth, we show up when we say we will, and the person at your door is exactly who we said they would be.

FAQs – Furnace Repair

How much does furnace repair cost in Jacksonville?

Most furnace repairs in Jacksonville cost between $150 and $650, depending on the component that failed. Simple fixes like a flame sensor cleaning run under $200, while a blower motor or control board replacement can run $350 to $650. Every repair at Brandt HVAC Co Jacksonville starts with a written, no-obligation estimate so the price is confirmed before any work begins. Call (904) 456-0205 for an exact quote on your specific furnace.

How fast can you get to my home for a furnace repair?

Most furnace repair calls in Jacksonville can be scheduled the same day, and our phones are answered 24 hours a day, 7 days a week by a live person. If your heat is out on a cold night, we prioritize no-heat calls and can often have a technician to you within hours, not days.

Is it cheaper to repair or replace a furnace?

As a general rule, if the repair costs less than 30% of the price of a new furnace and your furnace is under 15 years old, repairing makes sense. Once a furnace passes 18 to 20 years and needs a major component like a heat exchanger or a blower motor, replacement usually becomes the better long-term decision. We will always give you an honest recommendation with real numbers so you can decide with confidence, not pressure.

Will the technician be someone I can trust in my home?

Yes. Every Brandt HVAC technician is background-checked and identity-verified through the Threshold Verified standard. Before your appointment, we send you the technician’s name and photo. When they arrive, they wear a branded uniform and show you a photo ID badge at the door before entering your home. This is a non-negotiable part of how we operate, not a courtesy.
