Lennox furnace repair in Tampa typically costs between $150 and $700, depending on the part that failed and which Lennox series you have. Most repairs are done the same day we diagnose the unit, and you get a written price before we touch anything. So no surprises at the door, and no wondering whether the tech is padding the bill.
This page is for Tampa homeowners with a Lennox gas furnace that’s short-cycling, making noise, blowing cold air, or refusing to start at all. If that’s you, call (850) 608-1463 to talk to a live person who can book a same-day diagnostic and get you a straight answer.
How Lennox Products Fail – and How We Fix Them
- Elite® Series (EL296E, EL296V) pressure switch faults. These modulating and two-stage furnaces rely on a pressure switch to confirm the inducer motor is pulling air through the heat exchanger. In Tampa’s humidity, condensation can collect in the pressure switch hose and trip a false fault code. We see this constantly on EL296 units in older Tampa homes near the bay. The fix is usually cleaning the hose and re-testing condensation drainage – not replacing the switch, which saves you about $200 compared to what a parts-swapping tech might do.
- Merit® Series (ML193, ML296) ignitor failures. The ML series uses a hot surface ignitor, a thin ceramic piece that glows red to light the gas. After 8 – 12 years, it cracks. The symptom is specific: the inducer motor spins, the gas valve clicks, but no flame. We replace the ignitor with an OEM-grade part and verify gas pressure while we’re in there, because low pressure from a failing regulator is the second most common cause of the same symptom.
- Dave Lennox Signature® Collection (SLP98V, SLP99V) heat exchanger issues. These high-efficiency modulating furnaces use a clamshell alloy heat exchanger that can develop hairline cracks near the weld seams after years of heating cycles. The tell is usually a faint chemical smell at the registers and declining temperature rise. We inspect with a combustion analyzer during repair calls because a cracked heat exchanger is a carbon monoxide risk and needs to be caught early.
- G61MPV and G71MPP blower motor capacitor failures. These older Lennox workhorses are still in hundreds of Tampa homes built in the 2000s. The blower motor capacitor, a small cylinder that gives the fan motor its starting jolt, fails gradually. You’ll notice the blower humming but not spinning, or slow airflow at the vents. We stock capacitors for these legacy units because they’re still worth repairing when the rest of the furnace is solid.
- ML180 and EL180 rollout switch trips caused by dirty secondary heat exchangers. If you own an 80% efficiency Lennox furnace and it shuts down after a few minutes with a rollout or limit code, it’s often a coated secondary heat exchanger reducing airflow. Tampa dust, pet hair, and yes, that salt air near Channelside, accelerates the buildup. We clean the exchanger and check the airflow path before resetting anything.

Our Lennox Furnace Repair Process
- 1
You call or book online. A live person answers, takes your Lennox model number and symptoms, and schedules a window with a live arrival time you can track on your phone.
- 2
We diagnose before we quote. Your tech runs the furnace through its sequence of operations, checks the control board for stored fault codes, and measures things like gas pressure, inducer current draw, and temperature rise.
- 3
You get a written price. Before any repair, we hand you a number in writing. If the job needs a part we don’t have on the truck, we tell you the exact cost and time to source it.
- 4
We repair with the right part. On newer Lennox units still under warranty, we use OEM parts so we don’t void your coverage. On older units where a quality aftermarket part is actually the better value, we’ll say so plainly and let you decide.
- 5
We test the full cycle. After the repair, we run the furnace through multiple cycles, verify the temperature rise matches the data plate, and check for any secondary issues starting to show.
- 6
You get the guarantee in writing. Every repair is covered by our 365-Day Done Right Promise. If the same issue comes back within the coverage window, we return at no charge and make it right.
What Lennox Furnace Repair Costs in Tampa
Most Lennox furnace repairs in Tampa run $150 to $700. On the low end, you’re looking at things like a pressure switch hose cleaning, a flame sensor cleaning, or a thermostat calibration. On the high end, a blower motor replacement or a gas valve replacement on a Signature series unit can push toward that $700 mark.
Here’s how common Lennox repairs break down in Tampa:
- Flame sensor cleaning or replacement: $150 – $250
- Ignitor replacement: $200 – $375
- Pressure switch replacement: $180 – $350
- Blower motor replacement: $400 – $700
- Gas valve replacement: $350 – $650
- Control board replacement: $300 – $600
What moves the price: which Lennox series you own, whether the unit is under warranty, and whether the failed part damaged anything else. You always get a written price before we start, and the diagnostic call carries a straightforward estimate you can hold us to. Call (850) 608-1463 for an exact quote.

We’re an independent Lennox service provider, which means we answer to you, not to a manufacturer’s sales quotas. Andre Fuller built this company in 2004 with one idea: put the price and the guarantee in writing before anyone touches a unit, because that’s how he’d want to be treated. Get the price in writing first – then we get to work.
Our techs see Lennox furnaces every week, from SLP98Vs in Hyde Park to aging ML180s out in Brandon. They know the fault codes, they know the weak points, and they know what parts to stock. And if your Lennox has reached the end of its life, we service Carrier and Trane too, so you get an honest repair-vs-replace comparison without a brand sales pitch.
Every Lennox repair comes with our 365-Day Done Right Promise in writing. If the repair fails within the coverage window, we return at no charge. That’s not an upgrade or a sales gimmick. It’s just the way we run every job.
FAQs
If your Lennox furnace is still under the manufacturer’s warranty, we use OEM parts on covered components so your warranty stays intact. Lennox warranties cover parts, not labor. Our repair labor is covered separately by our own written guarantee, the 365-Day Done Right Promise, which covers the work we do for a full year. Call (850) 608-1463 and we’ll check your serial number to see what warranty remains.
Most Lennox furnace repairs in Tampa are diagnosed and completed the same day, assuming the part is on our truck or available locally. Ignitors, pressure switches, flame sensors, and capacitors are stocked on our service vans because they fail most often. For less common parts like Signature series control boards, we source from local distributors and typically return within 1 – 2 business days.
If the repair is under $500 and your Lennox is less than 12 years old, repair almost always makes sense. If you’re looking at a failed heat exchanger on a 15+ year old ML series, or a second major repair within a year, replacement starts to win that math. We’ll give you both numbers in writing and tell you which one we’d recommend for your specific unit, not just the one with a higher ticket. Call (850) 608-1463 for an honest answer.
In Tampa, we see more pressure switch condensation faults and dirty heat exchangers than colder-climate contractors would. The humidity here means the furnace sits idle for long stretches, then cycles on during cold snaps, and condensation builds in the pressure switch tubing. Salt air near the bay and Channelside accelerates corrosion on furnace cabinets and electrical connections. We check for these Tampa-specific issues on every Lennox diagnostic.
Yes. We service the entire Lennox furnace lineup found in Tampa homes, including the Merit series (ML193, ML296), Elite series (EL296E, EL296V), and Dave Lennox Signature Collection (SLP98V, SLP99V). We also still repair the older G61, G71, and G26 units that are aging out in neighborhoods around Tampa. If it says Lennox on the data plate, we’ll diagnose it.
