Furnace Repair in San Antonio, TX

Furnace Repair in San Antonio, TX

Furnace repair in San Antonio typically costs between $150 and $650 depending on the part that failed, and most repairs are done the same day we diagnose the problem. If your furnace is blowing cold air, cycling on and off, or making sounds it never made before, the fix usually comes down to a failed igniter, a worn blower motor, a cracked heat exchanger, or a control board that’s given up. Our Heating & Furnace team at Meadowsweet Heating and Air San Antonio handles all of it, on equipment from Rheem, Bryant, Daikin, and York, with a written price before any work starts. Call (254) 271-2545 and a live person answers, day or night.

We know a furnace that quits in January in San Antonio isn’t just an inconvenience. It’s a cold house, a rearranged schedule, and kids who can’t sleep. Luis Serrano and the rest of our crew get that, and we plan every repair visit around it.

When You Need Furnace Repair

San Antonio winters are mild compared to the Midwest, but January nights still drop into the 30s, and a furnace that’s been idle since March can fail the first cold snap you ask it to work. These are the symptoms that mean it’s time to call:

• The furnace blows cold air. Usually the igniter or flame sensor has failed. The burners light, then shut off, and the blower pushes unheated air through the vents.
• It cycles on and off every few minutes. Short cycling is often a dirty flame sensor or an overheating limit switch. It wastes gas and wears down the blower motor faster than it should.
• You hear a loud bang when it starts. Delayed ignition, common on aging gas furnaces, means gas builds up before the burners catch. It’s loud and worth fixing before it gets worse.
• The furnace runs but some rooms never warm up. Duct leaks, a failing blower motor, or a clogged filter can starve the far bedrooms of heat while the living room stays toasty.
• Your gas bill jumps without explanation. A furnace working harder than it should will show up on the CPS Energy bill. Losing efficiency is a slower failure, but it costs real money every month.
• The carbon monoxide detector goes off. This is the one that can’t wait. Turn the furnace off, open a window, and call us. A cracked heat exchanger can leak CO into the house, and we take that call ahead of everything else.

If you’re anywhere in San Antonio, from Alamo Heights to Stone Oak to the far west side near SeaWorld, we’ll send a background-checked, uniformed technician who arrives with drop cloths and shoe covers in hand.

Our Furnace Repair Process

1. You call, a person answers. No voicemail queue, no call-back in 48 hours. You’ll talk to someone at (254) 271-2545 who takes down what you’re seeing and schedules a window that works for you.
2. The technician arrives and protects the house first. Shoe covers go on before the door opens. Drop cloths go under the furnace and along the path from the door to the equipment, including any hallway where kids and pets walk.
3. We diagnose the problem and show you the written price. Before any work starts, you get a line-item price in writing. The C.A.R.E. values code we work under means the price is explained in plain terms: what failed, what it costs, and what your options are.
4. The repair is done, and we clean up like it’s our own home. Every tool, every screw, every scrap of wire leaves with us. We’ll send you a photo of the finished clean-up before the crew pulls out of the driveway.
5. You’re covered for a full year. The 365-Day Done Right Promise means if the repair isn’t right, we come back and fix it. No runarounds, no fine print.

Furnace Repair Pricing in San Antonio

What you’ll pay depends mostly on what failed. Here’s what families across San Antonio can expect:

Repair Type	Typical Cost Range
Flame sensor cleaning or replacement	$100 – $180
Igniter replacement	$160 – $300
Thermostat replacement	$120 – $260
Blower motor replacement	$350 – $650
Control board replacement	$280 – $550
Heat exchanger replacement	$650 – $1,400

Three things move the price in San Antonio. First, the age of your furnace: parts for a 20-year-old unit take longer to source than parts for a five-year-old Rheem. Second, the part itself: a blower motor costs more than a flame sensor, and labor varies with how deep into the cabinet the part sits. Third, the brand: we service all nine major brands, but some parts are pricier than others. A York control board and a Daikin control board aren’t the same cost.

Every estimate is free. The price we quote you is the price you pay, in writing, before work begins. Call (254) 271-2545 and we’ll come take a look.

Furnaces We Service Across San Antonio

Our technicians work on gas furnaces, electric furnaces, and heat pump backup systems in homes from the King William district up through Hollywood Park. We carry common parts for all nine brands we service, which means fewer second trips and faster fixes for families who need heat tonight. If you’ve got a Bryant furnace that’s been in the house since you moved in, or a Rheem that the previous owner installed, we know the equipment and we know how to source what it needs.

Part of the Cedarwell family of HVAC companies since 2004, Meadowsweet Heating and Air San Antonio has spent two decades around San Antonio’s specific heating quirks: furnaces that sit unused for nine months and then get asked to run hard in February, dust from construction and cedar season clogging burners and blowers, and homes built in the 1980s and 1990s that are now hitting the end of their original furnace’s life.

Why the Cedarwell Care Promise Matters for Your Family

Most HVAC companies stop at fixing the system. We’re accountable for how the house looks and feels when the crew leaves, because that’s the part families with kids and pets actually remember.

Here’s what that looks like in practice. Your toddler’s play mat stays clean because drop cloths go down before the work starts. Your dog doesn’t track anything through the house because shoes never touch your floor. Your sleeping baby’s nap isn’t interrupted by a blaring radio in the driveway, because our crew respects quiet hours. And you get a photo of the clean-up before the crew pulls away, so you can see the space is right without having to come home and check.

Luis Serrano built this standard into how we work because he’s spent enough time in other people’s homes to know what actually matters: a crew that asks before moving the coat rack, explains the price without jargon, and leaves the hallway cleaner than they found it.

FAQs – Furnace Repair

Is it cheaper to repair or replace a furnace in San Antonio?

If your furnace is under 12 years old and the repair is under $650, repairing is almost always the better financial call. If the unit is over 15 years old and the repair is a heat exchanger or blower motor, replacement starts to make more sense, especially since a new furnace will run noticeably more efficient than one built in 2008. We’ll give you both numbers in writing and let you decide. Call (254) 271-2545 for an honest assessment, not a sales pitch.

Can you repair my furnace the same day?

In most cases, yes. We stock common parts for Rheem, York, Bryant, Daikin, and the other major brands on our trucks, and we’re in San Antonio neighborhoods every day. When a part has to be ordered, we’ll tell you that upfront and give you a realistic timeline. Nights and weekends are no different: a live person answers the phone 24/7.

How much does a furnace repair cost in San Antonio?

Most repairs fall between $150 and $650. A simple flame sensor cleaning runs about $100 to $180, while a blower motor replacement runs $350 to $650. The heat exchanger is the expensive one at $650 to $1,400, and at that point we’ll walk you through whether replacement is the smarter spend. Estimates are free, and the price we quote is the price you pay.

Do you service my furnace brand?

We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The nine brands cover the vast majority of furnaces installed in San Antonio homes over the last two decades. If you’re not sure what you have, tell us over the phone and we’ll figure it out together.

What should I check before calling for furnace repair?

Check the thermostat is set to heat and the filter isn’t clogged. A dirty filter is the most common cause of overheating and short cycling, and it’s a two-minute fix that costs ten dollars. Check that the gas valve to the furnace is open and the breaker hasn’t tripped. If all of that looks right and the furnace still isn’t heating, call (254) 271-2545 and we’ll come diagnose it.

Is it safe to keep using my furnace if it’s making a banging sound?

The banging sound is delayed ignition, where gas builds up before the burners light, and it’s not something to ignore. The furnace is designed to contain that ignition, but the force over time can crack the heat exchanger. Carbon monoxide is a real risk with a cracked heat exchanger, which is why we recommend shutting the furnace off and having a trained professional inspect it rather than continuing to run it. Call us and we’ll come out.
