AfterFast, Reliable Furnace Repair Across Longwood
Furnace repair in Longwood typically costs $150 to $700 for most jobs, and we can usually get a technician to your door the same day you call. Longwood’s housing stock has a specific set of problems we’ve come to know well: 1970s and 80s concrete block homes with original ductwork failing in attics that hit 150°F, and Historic District wood-frame houses that need a slower, more careful hand. If your heat is out or short-cycling, call (747) 966-3037 and a live person will answer, day or night.
At Meadowsweet Heating & Air, we service furnaces across Longwood, from the neighborhoods along SR 434 to the CR 427 corridor. Luis Serrano leads our team, and every job includes a written price before we turn a single screw. No surprises, no pressure.
Why Meadowsweet Heating & Air Is Longwood’s Preferred Furnace Repair Company
Longwood homeowners call us because we understand what’s inside their walls. Homes built in this city’s 1970s and 80s boom share a common set of issues: flex duct that has separated from ceiling registers, blower motors running hot against collapsed static pressure, and heat exchangers stressed by years of restricted airflow. A technician who only knows newer Lake Mary builds will chase the furnace itself and miss the duct failure behind it. We don’t.
Luis Serrano and the crew run on a simple system called the C.A.R.E. values code: Clean up like it’s our own home, Ask before moving anything, Respect your family’s time and quiet hours, Explain the price before the work. Shoe covers and drop cloths go down on every visit. Before we leave, you get a photo of the clean-up. That’s the Cedarwell Care Promise, the standard behind every job since 2004.
And when you call (747) 966-3037, a live person picks up. Not a voicemail queue. Nights, weekends, holidays. That matters when your furnace quits on a 38°F February morning in Longwood.

Gas Furnace Repair in Longwood
Gas Furnace Repair in Longwood means working on systems often installed when Jimmy Carter was president. The job usually involves diagnosing why the furnace won’t light, won’t stay lit, or won’t push warm air, then repairing or replacing the failed component: gas valves, ignitors, flame sensors, blower motors, or pressure switches. In Longwood’s 1970s and 80s homes, the problem is frequently not the gas side at all. Collapsed flex duct in a hot attic strangles airflow, drives up static pressure, and makes a perfectly good gas valve look lazy. We check the duct run before condemning the furnace. Gas furnace repair in Longwood runs $150 to $700, diagnostic included.
Ignitor and Flame Sensor Replacement
Older gas furnaces in Longwood, especially Bryant, Rheem, and Goodman units from the 80s and 90s, fail to light when the silicon nitride ignitor cracks or the flame sensor builds up oxidation. We carry common ignitors and sensors on the truck, so most of these jobs finish in one visit. The part is small; the labor is straightforward; the price is written before we start.
Gas Valve and Burner Service
When a gas valve sticks or the burners corrode, you might smell gas or the furnace will lock out entirely. We test the gas supply at the valve, inspect the manifold pressure, and clean the burner tubes before replacing anything. Longwood’s attic humidity accelerates corrosion on burner surfaces, and a furnace that sits idle through Florida’s long cooling season tends to collect rust that a heating cycle then reveals.
Furnace Tune Up in Longwood
Furnace Tune Up in Longwood is an annual inspection and cleaning that costs $80 to $200, and in our view it’s the single best defense against the specific failures this city’s older homes throw at furnaces. A tune-up includes checking the heat exchanger for cracks, testing the ignitor and flame sensor, measuring gas pressure, inspecting the blower motor and belt, and verifying the thermostat’s response. On a 1980s Longwood furnace, we also look hard at the duct static pressure, because that’s where the real trouble hides.
Heat Exchanger Inspection
Heat exchanger cracks are the failure we most want to catch before they matter. In Longwood’s 40-to-50-year-old furnaces, a cracked exchanger can release combustion gases into the living space. We visually inspect what’s visible, run a flame test for drafts, and measure CO at the supply register. If the exchanger is compromised, we say so plainly and quote replacement options. Safety isn’t up for negotiation.
Blower Motor and Static Pressure Check
Longwood’s original ductwork, run through unconditioned attics and degraded by 140-150°F heat, often starves the blower motor. The motor runs hot, pulls high amps, and eventually fails. During a tune-up, we measure static pressure on both the supply and return side. If the numbers are out of range, we show you the readings and explain what’s causing it. A $99 tune-up that catches a collapsing duct before it kills a $600 blower motor is money well spent.
Trusted Brands We Service in Longwood
Meadowsweet Heating & Air services furnaces from Goodman, Rheem, York, and Daikin, along with Carrier, Trane, Lennox, and Bryant. For Longwood customers, that matters because the city’s older housing stock leans heavily on brands installed during the 1980s and 90s. We stock common ignitors, flame sensors, pressure switches, and capacitors locally, so parts for a 1987 Goodman or a 1992 Rheem don’t mean a week of waiting. A live person answers 24/7, and if we don’t have the part on the truck, we can source it fast and keep your family warm.
Common Furnace Repair Problems We See in Longwood Homes
- Short-cycling from collapsed flex duct. In Longwood’s 1970s and 80s CBS subdivisions along CR 427 and SR 434, original flex-duct boots have physically separated from ceiling registers. The furnace reaches temperature, shuts off, then fires again minutes later because the heat never reaches the rooms. We find this on roughly half the no-heat calls in older Longwood neighborhoods.
- Blower motor burnout from high static pressure. When original ductwork is undersized or collapsed, the blower motor works against resistance it was never designed for. Motors overheat, windings degrade, and the motor fails. Replacing the motor without fixing the duct just means you’ll replace it again in a few years.
- Control-board failures from lightning-driven surges. Longwood sits fully inland in Seminole County, with no lake-breeze moderation from the violent afternoon thunderstorms that sweep the I-4 corridor in summer. Surges travel through the low-voltage furnace circuit and take out control boards and capacitors. We see a spike in these calls from June through September, even though the furnace isn’t running.
- Heat exchanger stress from years of restricted airflow. Cracked heat exchangers in Longwood are rarely a sudden failure. They’re the end result of a decade of collapsed ducts and dirty blowers forcing the exchanger to overheat and contract. This is why we inspect ducts on every furnace repair, not just the furnace.

FAQs About Furnace Repair in Longwood
Because the furnace is almost never the problem. In Longwood’s 1970s and 80s CBS homes, the original flex duct has usually separated from the ceiling registers or collapsed in the attic. The furnace heats up, reaches the thermostat setting, and shuts off, but the warm air never actually reaches the rooms. A tune-up that doesn’t measure duct static pressure will miss this. We measure it on every call. Call (747) 966-3037 and we’ll tell you what’s actually wrong.
Start with the ductwork. In Longwood’s older subdivisions, collapsed or disconnected flex duct accounts for a large share of “furnace problems” that turn out to be distribution failures. If the furnace ignites, the blower runs, and the heat exchanger is intact, the issue is likely in the attic. We diagnose in this order: duct static pressure, blower motor performance, then the gas side. Replacing a furnace without fixing the ducts wastes money and leaves you with cold rooms. A written diagnosis from our team will show you exactly what’s failing before you spend a dollar on replacement.
A furnace tune-up for a 1980s Longwood home costs $80 to $200 and includes everything a standard tune-up does, plus two things specific to this city’s housing stock. First, we inspect the heat exchanger for cracks, because 40-to-50-year-old exchangers stressed by years of collapsed ducts are the ones that fail. Second, we measure static pressure on the supply and return side to detect the duct restrictions that kill blower motors. You get a written report of what we found, what we fixed, and what we’d watch. We don’t pay technicians on what they sell, so the report is honest.
R-22 equipment can still be repaired, especially if the issue is a capacitor, contactor, or control board rather than a refrigerant leak. However, R-22 is no longer manufactured or imported in the United States, and remaining supplies are expensive. If your system needs a refrigerant charge, you’re usually better off putting that money toward a replacement system designed for R-410A or a modern low-GWP alternative. In Longwood, where many homes still run original R-22 condensers paired with aging furnaces, we’ll give you the repair quote and the replacement quote side by side so you can decide with real numbers.

Yes. Longwood’s Historic District includes early-20th-century wood-frame homes that require careful planning for any furnace, air-handler, or duct work. The air-handler placement has to be chosen so it won’t torque floor joists or compromise the structural shell. Interior duct runs often need to fit through walls that were never designed for them. We approach these homes slowly, protect the floors with drop cloths, and use quiet tools during school and nap hours. The crews at Meadowsweet Heating & Air size every repair to the house, not the other way around.
When your heat is out in Longwood, you want someone who knows this city’s houses, not someone learning them on your dime. We know the difference between a failed gas valve and a collapsed duct. We’ll tell you the truth, write the price before we start, and leave your floors clean. Call (747) 966-3037 for a free estimate, or ask for Luis Serrano and he’ll walk you through what’s happening.
