AfterFast, Reliable Furnace Repair Across Knoxville
Furnace repair in Knoxville typically runs $150-$700, and most calls get a same-day or next-day visit. We work on furnaces throughout the Tennessee River valley, from North Knoxville ranch homes to rural properties past Karns and Corryton where propane does the heating because natural gas lines never reached the road. If your heat is out on a cold night, call (747) 966-3037 and a live person answers, not a voicemail queue.
Luis Serrano leads our Knoxville service area. He keeps crews coordinated out of the brand’s Memphis office, but the technicians who show up at your door work the Knoxville metro every week. They know the difference between a 1960s electric furnace in East Knoxville and a propane system on an exposed ridgeline in Seymour, because they drive both routes regularly.
Why Meadowsweet Heating & Air Is Knoxville’s Preferred Furnace Repair Company
Knoxville homeowners call us for furnace repair because we show up with a written price before any work starts, every single time. That price is honest, itemized, and explained by a background-checked, uniformed technician. No estimates over the phone with a big range that balloons once someone opens the furnace cabinet. What you’re quoted is what you pay.
We’re part of the Cedarwell family of HVAC companies, established in 2004. The Cedarwell Care Promise guides every furnace repair visit in Knoxville: a written price up front, shoe covers and drop cloths protecting your floors, and a photo of the clean-up sent before the crew leaves. Every job is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print.
Families in Knoxville tell us the same thing: they want a furnace fixed without worrying about muddy boots in the hallway or the tech leaving fasteners on the living room floor. Our crews follow the C.A.R.E. values code on every visit. Clean up like it’s their own home. Ask before moving anything. Respect quiet hours when kids are napping. Explain the price before the work. A live person answers our phone 24 hours a day, 7 days a week, including holidays when a furnace picks the worst possible moment to quit.
Furnace Tune Up in Knoxville
A Furnace Tune Up in Knoxville runs $80-$200 and is the single most effective way to keep your heating system from failing during the ice storms that routinely hit the Tennessee Valley in January and February. We inspect the burners or heating elements, test the heat exchanger, check gas pressure on propane systems, measure airflow through the blower, and calibrate the thermostat. For Knoxville homes with vented crawl spaces, we also look at the duct connections and insulation where conditioned air leaks into damp dirt.
Propane Pressure Check
On rural Knoxville properties where natural gas isn’t available, furnace owners often swap propane tanks or have a regulator replaced and never have the manifold pressure re-set. The furnace starts sooting, short-cycling, or tripping the limit switch. During a tune-up we verify pressure matches the manufacturer’s spec for your outdoor unit and altitude, which prevents misdiagnosis down the road.
Electric Furnace Element Test
Homes in North and East Knoxville built from the 1950s through the 1980s frequently still run on electric strip heat. We test each resistance element individually, check the sequencer that stages them, and make sure the blower motor and capacitor are moving enough air. Failed elements are the reason many of these older furnaces blow lukewarm or cold air even though the thermostat says the heat is on.
Emergency Furnace Repair in Knoxville
Emergency Furnace Repair in Knoxville is available 24 hours a day through our live-answer phone line at (747) 966-3037. We don’t route you to an answering service. A real person answers, takes your address and what the furnace is doing, and dispatches a technician the same day or overnight depending on where you are in the metro. Typical emergency repair costs fall in the $150-$700 range depending on what’s failed.
No-Heat Calls in Winter
When temperatures drop into the teens and your furnace won’t fire, this isn’t a comfort issue. It’s a health risk, especially for households with infants, elderly family members, or pets. We prioritize no-heat calls across Knoxville and the surrounding communities in Powell, Seymour, Louisville, and Clinton. If your home runs on propane and the tank is low, tell us on the phone so we can coordinate a refill check before we arrive.
Short Cycling and Tripping Breakers
A furnace that starts, runs three minutes, shuts off, and repeats is short cycling. In Knoxville we see this most often on propane systems where gas pressure is off after a refill, and on older electric furnaces where a strip-heat element has failed and the breaker trips to protect the circuit. These aren’t problems to reset and ignore. They get worse, and in a workshop or outbuilding, a failed system can freeze pipes overnight.
Trusted Brands We Service in Knoxville
Our technicians service furnaces from Trane, Lennox, Goodman, Rheem, and the other major equipment lines we support across all nine brands we carry parts for. We stock common ignitors, flame sensors, capacitors, pressure switches, and gas valves locally for Knoxville dispatch, which means many furnace repairs are completed same-day without waiting on a parts shipment. If you have a Trane propane furnace at a rural property or a Goodman electric furnace in an East Knoxville mid-century ranch, we know these systems well and can usually diagnose them faster because we see them every week.
Common Furnace Repair Problems We See in Knoxville Homes
- Propane furnaces sooting after a tank swap. Rural Knoxville homeowners often get a new propane tank or a pressure regulator swap and the furnace never runs right afterward. The gas pressure is no longer matched to the furnace, or the burners were never cleaned, and the system soots up and short-cycles until it’s fixed.
- Electric strip-heat furnaces with one dead element. In houses built during TVA’s cheap-power era, electric furnaces from the 1960s and 70s use staged resistance elements. When one burns out, the system still runs but blows air that never feels warm, and static pressure through undersized original ductwork makes it worse.
- Mold-degraded ductwork in vented crawl spaces. Knoxville sits in the Tennessee River valley where humidity gets trapped by the surrounding ridges. Ductwork in unencapsulated crawl spaces absorbs that moisture, insulation turns black, and flex duct partially collapses. A furnace repair often turns into a duct remediation once we see what’s down there.
- Oversized or undersized systems on exposed properties. Homes on ridgelines and valley floors around Knoxville experience cold-air drainage that drops temperatures several degrees below nearby hilltops. Without wind shelter, a furnace sized for a protected neighborhood runs constantly or cycles too often, especially in detached workshops and outbuildings.
Pricing for Furnace Repair in Knoxville, TN
Furnace repair in Knoxville falls between $150 and $700 on most service calls. A furnace tune-up runs $80-$200. The spread depends on what’s actually failed: an ignitor, flame sensor, or capacitor replacement lands on the lower end, while a blower motor replacement or heat exchanger repair lands higher. What moves a Knoxville furnace repair toward the top of the range is crawl-space access, multiple failed components, or ductwork remediation that reveals itself once we open things up.

| Furnace Repair | $150-$700 |
| Furnace Tune-Up | $80-$200 |
Every estimate is free. We provide a written price before any work starts, whether that’s a quick ignitor swap in a Knoxville neighborhood or a longer propane furnace repair on a rural property past the county line. Call (747) 966-3037 and we’ll schedule a visit and tell you honestly what the repair will cost before a single tool comes out.
One thing worth understanding about older Knoxville homes: because TVA’s historically cheap electricity made electric strip heat the default from the 1950s through the 1980s, furnace repair here frequently means troubleshooting resistance-heat elements in a 1960s-70s electric furnace rather than a gas burner. That’s a service profile that barely exists in most U.S. metro markets. We see it every week in North Knoxville and East Knoxville, and our diagnostics are built around it.

FAQs About Furnace Repair in Knoxville
Yes, we repair propane furnaces throughout Knoxville and the rural communities north of the city where natural gas lines never reached. Propane furnaces need specific gas-pressure verification, burner cleaning, and combustion testing that’s different from natural gas systems. We carry the test equipment and replacement parts for propane systems on our trucks.
If you’re buying the house, schedule a tune-up after closing and before the first cold snap. Sellers often skip furnace maintenance, and a propane system that hasn’t been checked in a few years can hide clogged orifices or a failing blower capacitor that only shows up when you need real heat. Call (747) 966-3037 for a written price.
It depends on what’s failed and the condition of your ductwork. A simple element or sequencer replacement on an older electric furnace can run $150-$400 and buys you reliable heat, but if the heat exchanger is degraded or the ductwork in your crawl space is mold-damaged and undersized, you’re putting money into a sinking foundation.
Many Knoxville homeowners with 1960s-70s electric furnaces end up converting to a heat pump, especially as TVA electricity rates have risen significantly from what they were when those homes were built. We’ll give you a straight assessment: if a $200 repair gets you three more reliable winters, we’ll say so. If a conversion is the better long-term move, we’ll explain the numbers and handle the rebate paperwork. Call (747) 966-3037 for an honest evaluation.
Valley-floor neighborhoods around Knoxville sit in cold-air drainage zones. When cold air settles at night, it flows downhill and pools in the Tennessee River valley, dropping temperatures several degrees below nearby hilltops. Your neighbor up the ridge may sit 15 feet higher in elevation but 6 degrees warmer at 6 a.m. Your furnace isn’t necessarily malfunctioning. It’s just carrying a heavier load.
That said, if your furnace runs constantly and the house still feels cold, airflow through the ductwork may be restricted by collapsed flex duct or mold-insulated seams in a damp crawl space. We see that constantly in mid-century Knoxville homes. A furnace tune-up with an airflow check answers the question definitively. Call (747) 966-3037.
Yes, we do. Workshops, detached garages, and outbuildings on rural Knoxville properties need their own furnace or heating system, and those units fail for different reasons than house systems. They’re exposed to wind, they sit on concrete, and they’re often sized wrong for the real heating load because the building was never load-calculated.
We sent our tech out past the county line toward the Karns community, where a homeowner runs a propane furnace because natural gas never reached their road. The complaint was short cycles and cold rooms in a shop building. Our tech pulled the burners, found a clogged orifice and a failing capacitor on the blower motor, verified the heat exchanger was clean, then ran a load calculation to confirm the oversized tonnage was fighting the building’s exposed, unsheltered position. We re-set the propane manifold pressure, replaced the capacitor, and added a thermostat calibration so the house and outbuilding zones stopped calling for heat at the same time. That’s a standard call for us, not an unusual one. Call (747) 966-3037 and describe your outbuilding setup. We’ll bring the right test equipment.
Most furnace repairs in Knoxville run $150-$700, with furnace tune-ups at $80-$200. Simple fixes like an ignitor, flame sensor, or capacitor replacement sit at the lower end. A blower motor replacement, heat exchanger repair, or gas valve replacement climbs toward the top of that range. Ductwork remediation discovered during a repair adds cost but is something we show you before any additional work proceeds.
We give every Knoxville homeowner a written price before work starts. No one sees a surprise invoice at the end. Call (747) 966-3037 for a free estimate, and we’ll tell you exactly what your furnace repair will cost.
