When your furnace stops heating in Katy, you need a repair crew that understands what they’re walking into. Furnace repair in Katy typically runs $150 – $700, and most jobs are diagnosed in a single visit. Our technicians know the difference between a Cinco Ranch subdivision furnace and a propane system out past FM 1463, because we’ve worked on both. If your heat is out or your burner won’t stay lit, call Luis and the team at Meadowsweet Heating and Air Houston at (346) 201-5395. A live person answers, day or night.
Why Meadowsweet Heating and Air Houston Is Katy’s Preferred Furnace Repair Company
We’re part of the Cedarwell family of HVAC companies, built since 2004 around one idea: the job isn’t done until your home looks and feels the way it should. Every Meadowsweet visit includes the Cedarwell Care Promise: a written price before any work starts, shoe covers and drop cloths inside the house, and a photo of the clean-up before the crew leaves. Katy homeowners tell us the same thing over and over: they’ve had repair crews leave dirt on the carpet and mystery charges on the invoice. That doesn’t happen here.
Luis Serrano leads our Katy service area with a simple standard. Background-checked, uniformed technicians follow the C.A.R.E. values code on every job: clean up like it’s their own home, ask before moving anything, respect the family’s time and quiet hours, and explain the price before the work begins. If there’s a sleeping baby or a nervous dog, we adjust. That’s not extra service. That’s the baseline.
Every repair is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print. Katy families ask about this more than almost anything else, and Luis will tell you the same thing he tells everyone: the promise is real, and it’s one reason our Furnace Repair team gets called back year after year.
Styles & brands we work with
Emergency Furnace Repair in Katy
Emergency Furnace Repair in Katy means getting heat back into a house when the temperature drops and the burners won’t fire. Out past the Grand Parkway, that’s not a minor inconvenience. It’s a cold night in a house with kids, and it needs a fast response. We dispatch locally to Katy, and our live-answer line at (346) 201-5395 means you talk to a person, not a voicemail queue, at 2 a.m. on a Sunday.
Propane Furnace Failures on Acreages
Homes north and west of I-10 often sit beyond natural-gas mains, which means propane. When a propane furnace fails, it’s usually one of three things: a regulator at the tank losing pressure, a sooted heat exchanger from a tank run low, or a gas valve not taking the signal. We diagnose the whole fuel path, from tank regulator to burner, not just the furnace cabinet.
Wind Load and Rollout Switch Trips
Exposed rural lots with no wind shelter push cold north wind through flue terminations. This causes rollout switch trips that keep repeating until a tech adds a concentric vent termination. If your furnace has been shutting down on the coldest nights and a previous tech shrugged, ask us to check the venting.
Furnace Maintenance in Katy
Furnace Maintenance in Katy is a $80 – $200 visit that catches the failures before they strand a family on a cold night. We inspect the heat exchanger, clean the burner assembly, check gas pressure (natural or propane), test the ignitor, and measure airflow. On rural properties, we also check the propane tank regulator and line pressure, because that’s where Katy acreage furnaces fail first.
Tune-Up Details That Matter Here
Katy’s humid winters, short as they are, push condensate through high-efficiency furnaces even in January. We check condensate drains and traps on every tune-up. A clogged drain on a 90%+ furnace will shut the unit down, and it’s a five-minute fix if caught early and a callback if not.
Written Report After Every Visit
After each maintenance visit, you get a written report of what was checked, what we found, and what it costs to fix anything that’s worn but not yet failed. Our technicians are not paid on what they sell. They’re paid to be accurate. Luis stands by that.
Trusted Brands We Service in Katy
We service Carrier, Trane, Lennox, and Goodman furnaces, along with Rheem, York, Daikin, Bryant, and American Standard. Katy’s rural stock leans toward Goodman and Trane 80% propane units, while newer Cinco Ranch and Cross Creek Ranch homes often run two-stage Carrier or Lennox systems. We keep common ignitors, flame sensors, gas valves, and blower motors stocked for these brands, so a repair doesn’t stall waiting on a part from across Houston. If you have a dual-fuel Carrier Infinity with propane backup out near FM 1463, we’ve been there. That combination is common on acreages, and we know its lockout modes.

AfterCommon Furnace Repair Problems We See in Katy Homes
- Propane regulator pressure loss. On unincorporated acreages, tanks run low and regulators lose pressure. The house won’t hold 68°F, and homeowners discover it only when the furnace runs constantly without reaching setpoint.
- Sooted heat exchangers from low tanks. A propane furnace on a nearly empty tank burns dirty. Carbon builds up in the heat exchanger, and eventually the flame rollout or high-limit trips. We see this regularly in Katy’s rural sectors.
- Workshop and outbuilding airflow problems. A furnace that’s fine in the main house trips high-limit in a converted barn or shop when a woodworking dust collector changes return airflow. Shared undersized ducts make it worse.
- Wind-driven rollout switch trips. Exposed properties with no wind shelter have flue terminations that catch north wind. The rollout switch trips on cold nights, and the fix is a concentric vent, not another switch replacement.

FAQs About Furnace Repair in Katy
We repair both, and we have extensive experience with propane systems on unincorporated acreages outside Katy city limits. Big swaths of Katy north and west of I-10 sit beyond natural-gas mains, so propane valve trains, buried line pressure, and dual-fuel heat-pump lockouts are regular work for our techs. That’s work that rarely shows up inside the Grand Parkway. Call (346) 201-5395 and tell us if you’re on propane.
Probably not, though it’s worth checking. On exposed lots with no wind shelter, a furnace that won’t reach temperature on north wind days usually points to wind load through the flue termination, causing rollout switch trips or flame instability. A sooted propane heat exchanger can also cause weak heat, and we’d check both. We’d start with a static pressure and combustion analysis, then fix the actual cause, not just reset the switch. Get an exact diagnosis by calling (346) 201-5395.
Your dust collector is changing the return airflow enough that the furnace trips its high-limit switch. This is common in converted outbuildings with shared or undersized ducts, because a woodworking dust collector pulls a lot of air and upsets static pressure. The furnace thinks it’s overheating and shuts down for safety. We’d check static pressure across the return, rebalance or reseal the ducting, and confirm the high-limit switch isn’t weakened. In Katy’s rural workshops, this is one of our most common calls.
Yes, we service dual-fuel Carrier Infinity, Trane, Lennox, and Goodman systems with propane backup on Katy acreages. Dual-fuel lockouts happen when the heat pump defrosts or when outdoor temperatures fall below the switchover setpoint and the propane furnace doesn’t take over as expected. We check the thermostat configuration, the outdoor sensor, and the gas valve signal path, then verify the board is commanding the right stage. These systems are common along FM 1463 and in Cross Creek Ranch, and we know their failure modes well.
Once a year, fall is best. Katy’s humid winters push condensation through high-efficiency furnaces even in mild weather, and on propane systems the regulator and line pressure need a yearly check that natural gas systems don’t. We also recommend a maintenance visit before the first real cold snap, especially on exposed acreages, because wind-driven venting problems reveal themselves then. A $80 – $200 maintenance visit catches a sooted heat exchanger or a weak ignitor before it strands a family. Call (346) 201-5395 to schedule.
Big swaths of Katy north and west of I-10 sit beyond natural-gas mains, so furnace repair here means diagnosing propane valve trains, buried line pressure, and dual-fuel heat-pump lockouts. Work that rarely shows up inside the Grand Parkway. Our techs drove 25 minutes past the energy corridor to a Cross Creek Ranch acreage off FM 1463 where a Trane 80% furnace was short-cycling on a cold snap. The blower motor was drawing high amps, and the propane regulator at the tank was causing a lazy flame. We replaced the blower capacitor and adjusted the gas valve, then checked static pressure across the shop’s ducted return. 0.62 inches water column. Spot on for the exposed steel building it heats. That’s the work we do for Katy, and we’re ready for your call.
