Fast, Reliable Furnace Repair Across Redwood
Furnace repair in Redwood typically runs between $150 and $700, depending on what failed and how deep into the system the problem sits. Most Redwood calls we handle are resolved in a single visit, and our techs carry parts for Goodman, Rheem, York, and Daikin equipment so we aren’t driving back to a supply house while your house sits cold. If your heat is out, call us at (747) 966-3037 and a live person answers, day or night.
What sets Redwood apart is the mix of homes on the route. A ranch property off FM 78 with a propane furnace from the 1990s sits twenty minutes from a new subdivision full of post-2021 heat-pump retrofits. We know both generations of equipment, and we know which one you’re likely running before we even pull into the drive.
Why Meadowsweet Heating & Air Is Redwood’s Preferred Furnace Repair Company
Meadowsweet Heating & Air is part of the Cedarwell family of HVAC companies, founded in 2004, and built around the Cedarwell Care Promise. In Redwood, that promise translates to something concrete: a written price before any work starts, background-checked uniformed technicians, and shoe covers and drop cloths on every visit so the red Guadalupe County dirt from the drive never ends up tracked across your floors.
Luis Serrano leads our team, and he’s built the Redwood service route around one idea: treat every home like it has a sleeping baby and a nervous dog. Our techs work under the C.A.R.E. values code. We clean up like it’s our own home, we ask before moving anything, we respect quiet hours, and we explain the price before the work. When the job is done, you get a photo of the clean-up before the crew leaves. That’s not an upsell. It’s the standard.
Every repair we make in Redwood is backed by the 365-Day Done Right Promise. If it isn’t done right, we make it right. No runarounds, no fine print.
Boiler Repair in Redwood
Boiler Repair in Redwood usually involves hydronic systems attached to older ranch homes, the ones built in the 1960s through 1980s when natural gas mains hadn’t yet made it past the corridor’s western edge. A boiler heating a home in Redwood is typically either a cast-iron propane-fired unit or an electric boiler in a home that never had a gas line run at all. Repair work here runs $150 to $700, depending on whether the issue is a circulator pump, an expansion tank, a zone valve, or the burner assembly itself.
Circulator Pump and Zone Valve Repairs
When a boiler fires but one room stays cold while the rest of the house warms, the problem is usually a failed circulator or a stuck zone valve. These are common on slab-built Redwood ranch homes where the hydronic loops run under concrete and any air in the lines causes uneven heating. We replace the pump or valve, bleed the system, and verify the thermostat is actually calling correctly before we leave.
Propane Boiler Burner Service
Rural Redwood homes without natural gas service rely on propane-fired boilers. If the burner won’t stay lit or the flame is lazy and yellow instead of sharp and blue, it’s often a dirty orifice or incorrect manifold pressure. We clean and adjust the burner, test combustion, and confirm the flue is drafting. Carbon monoxide is a real risk with any propane combustion appliance, so this is never a job to skip or rush.
Gas Furnace Repair in Redwood
Gas Furnace Repair in Redwood covers both ends of the service route. East of the corridor, some subdivisions have natural gas mains, and those homes run forced-air furnaces from Goodman, Rheem, York, and Daikin. West of Redwood, natural gas stops and the “gas furnace” is usually a propane conversion or a propane-dedicated unit. Diagnosis and repair on either runs $150 to $700, and the distinction matters because propane burners run at different manifold pressures than natural gas and need different orifice sizing.
Ignitor and Flame Sensor Failures
A gas furnace that clicks, tries to fire, then shuts down usually has a cracked ignitor or a fouled flame sensor. We see this constantly on Redwood homes where dusty attic air and the area’s persistent Gulf humidity coat the sensor rod with oxidation. The fix takes under an hour and costs on the lower end of the repair range.
Gas Valve and Manifold Pressure Problems
When a furnace runs but never reaches the thermostat setpoint, or when the flame burns weakly and the burner box soots up, the gas valve may be failing or the manifold pressure was never set for the fuel type. This matters more on propane conversions we see west of the Redwood corridor, where a furnace that was converted years ago may be running with the wrong spring in the valve. We test inlet and outlet pressure on every gas repair, not just the ones that look suspicious.
Trusted Brands We Service in Redwood
We service equipment from Goodman, Rheem, York, and Daikin, among others, and we stock common repair parts for these brands on our Redwood-bound trucks. That means a faulty ignitor, a failed blower motor capacitor, or a sticky gas valve on a Rheem or Goodman furnace doesn’t turn a one-hour repair into a two-day wait. For Redwood customers on a propane system or a recent heat-pump retrofit, we also carry universal parts that work across mixed-equipment installs, which are common out here where a new indoor unit gets matched to an older outdoor unit or vice versa.
Common Furnace Repair Problems We See in Redwood Homes
- Propane heat exchangers cracking after years without combustion analysis. On rural Redwood properties west of the natural gas mains, furnaces often fire for twenty seasons without anyone checking manifold pressure, flue draft, or heat exchanger integrity. We find cracks in exchangers that would have been caught years earlier with an annual tune-up.
- Post-2021 heat-pump retrofits short-cycling in heat mode. After Winter Storm Uri froze coils and burned out heat strips across Guadalupe County, a wave of heat pumps went in fast. Many landed on existing ductwork that was undersized for the original furnace, let alone a heat pump. We measure static pressure on every Redwood retrofit we touch, because airflow problems cause most of the short-cycling we see.
- Blower motors failing during hard freezes in under-insulated homes. Older Redwood ranch homes, especially pier-and-beam builds from the 1960s and 1970s, lose heat through the floor. The blower runs near constantly to compensate, and that heat strip on a heat-pump system draws high amps. Motors burn out. We replace them, then usually recommend the insulation conversation before the next freeze.
- Outbuilding and workshop furnaces running on improvised fuel lines. Redwood properties with workshops, barns, or detached garages often have a converted furnace or hanging heater installed years ago with whatever line was at hand. We repair these but we also check the gas line, the combustion air supply, and the venting, because a workshop heater vented poorly is a genuine hazard to anyone working inside.

What pushes a repair toward the top of the range here is usually access and age. A cracked heat exchanger on a 20-year-old propane furnace off FM 78 runs more than a dirty flame sensor on a three-year-old Goodman in a new subdivision. What rarely changes is the rate: we give a written price before any work starts, so the number you approve is the number you pay. Estimates are free. Call (747) 966-3037 and we’ll talk through what you’re hearing, smelling, or not feeling, then send a tech out.

FAQs About Furnace Repair in Redwood
Yes, we repair propane-fired furnaces regularly in Redwood, and we service more of them than natural gas units on this route. Propane furnaces need different manifold pressure settings and orifice sizing than natural gas units, and we test combustion and draft on every propane repair because the stakes are higher. Call (747) 966-3037 and tell us you’re on propane. We’ll bring the right manometer and the right parts.
Short-cycling on a post-2021 heat-pump retrofit in the Redwood area is usually caused by static pressure in ductwork that was never resized when the heat pump replaced a furnace. The unit moves more air than the ducts were designed for, trips a limit, shuts down, then restarts minutes later. We measure static pressure on every heat-pump repair we do here before touching refrigerant charge. It’s the local failure mode we see most on newer tract builds.
If the furnace runs and the house warms but you hear a loud hum or rattling, that points to the blower motor or capacitor. If the furnace won’t stay lit, the burner flame rolls out, or you smell a strange odor in the heat, the heat exchanger may be cracked. On older propane furnaces in rural Redwood homes, a cracked exchanger is common, and it’s also the one repair that should never wait. If you’re unsure, call (747) 966-3037 and describe exactly what you hear and smell. We’ll bring a combustion analyzer either way.
No, there’s no extra charge for rural Redwood properties west of the corridor or off FM 78. Our service route includes the surrounding Guadalupe County area, and pricing is the same whether your home is in a subdivision or on a ranch set back from the road. The only variable is the repair itself, and you’ll have the written price before any work begins.
Yes, we repair furnaces, hanging heaters, and converted propane units in workshops, barns, and detached garages throughout Redwood. We check the venting, combustion air, and gas line on every outbuilding repair, because improvised installations are common here and the margin for error in a smaller space is a lot thinner. If you’re heating a shop, call (747) 966-3037 and tell us what the unit is and where it’s mounted. We’ll treat the space like it matters, because it does.
