Get your free estimateFast, Reliable Furnace Repair Across Floresville
Furnace repair in Floresville typically runs $150 – $700, and most jobs are completed in a single visit. When your heat quits on a January night and the wind is blowing across the caliche flats, you need someone who knows Floresville homes, not a call center reading from a script. Our Furnace Repair team works on the systems actually installed in this part of Wilson County: older gas furnaces in 1970s brick veneer homes, newer high-efficiency units in the subdivisions off 181, and everything between. Call (361) 470-8872 and a live person answers, day or night.
We know Floresville because we work here. The pier-and-beam foundations, the shifting caliche soil, the long summer cooling season that leaves furnaces sitting idle for months before they are asked to fire on the first cold snap. That idle time creates its own problems, and we see them every winter.
Why Brandt HVAC Co San Antonio Is Floresville’s Preferred Furnace Repair Company
Floresville homeowners have a specific fear when they call for furnace repair: that the person at the door will be a stranger they know nothing about. We removed that uncertainty. When you book with Brandt HVAC, you get the technician’s name and photo before arrival. They show a photo ID badge at the door. Every technician is background-checked and identity-verified under the Threshold Verified standard. If someone shows up you were not told to expect, that visit is on us and we make it right.
Devin Marlowe leads our repair operation, and he has built the team around a simple rule: the homeowner should never wonder who is walking up the driveway. That matters in Floresville, where many of our customers are home alone during the day, have young children, or are older and cautious about who they let in. We are part of the Threshold Group family of home-service companies, established in 2003. This location is independently owned and operated, and dispatch is coordinated from the brand’s San Antonio office, with crews serving Floresville locally.
Every job, no exceptions, starts the same way: a written price before work begins. You see the number, you approve it, then we start. Every repair carries a written guarantee. If that repair fails within 365 days, we return at no charge under the 365-Day Done Right Promise. No argument, no invoice, no fine print.
Styles & brands we work with
Furnace Tune Up in Floresville
A Furnace Tune Up in Floresville costs $80 – $200 and is the single best defense against a mid-January breakdown in a house with original ductwork or an older gas furnace. We do not upsell you on parts you do not need. The tune-up involves cleaning the burners, checking the flame sensor, testing the ignitor, measuring gas pressure, inspecting the heat exchanger for cracks, and checking static pressure across the system. In Floresville, we spend extra time on one thing most companies skip: the duct connections under pier-and-beam homes. Loose joints there are the most common cause of “the furnace runs but the house stays cold.”
What the Tune-Up Report Shows You
You get a written report of what we found and what we recommend. You keep it. Use it next year, use it if you sell the house, use it if another company ever tells you something different. No one at Brandt HVAC is paid on what they sell during a tune-up, so the report tells you what the system needs, not what pads a commission check.
When to Schedule in Floresville
Book your tune-up in October or early November, before the first real cold front pushes through Wilson County. Once furnaces start running hard, our schedule fills within a day or two. If you missed the fall window, January is still better than waiting for the limit switch to trip on the coldest night of the year.
Emergency Furnace Repair in Floresville
Emergency Furnace Repair in Floresville runs $150 – $700 depending on the failed part and how long the diagnosis takes. A furnace that quits is not an inconvenience when the overnight temperature drops into the 30s. It is a health and safety issue, especially for older homeowners and families with infants. Our phones are staffed by a live person 24 hours a day, 7 days a week. No voicemail, no automated phone tree, no “leave a message and we will call you in the morning.”
Same-Night Response
We dispatch to Floresville from the San Antonio office, and most emergency calls are answered within hours, not days. If you are off Sutherland Springs Road, in the older neighborhoods near 4th Street, or out toward 181, we have a tech who knows those streets. You will know their name before they pull up.
No Overtime Charge
Emergency doesn’t mean a surprise surcharge at 2 a.m. Our written price is the written price, no overtime line item added because it is dark outside and cold inside. You approve the number before we touch a wrench.
Trusted Brands We Service in Floresville
Our techs work on Rheem, York, Daikin, and Bryant furnaces, along with every other major residential brand: Carrier, Trane, Lennox, Goodman, and American Standard. Because Floresville is served from a nearby metro parts supply, we can usually source capacitors, ignitors, gas valves, and blower motors same-day or next-morning. You are not waiting a week for a part to ship from a warehouse in another state. If your furnace is a York from the late 90s or a Daikin installed five years ago, we have seen it before and we know what fails on it.

AfterCommon Furnace Repair Problems We See in Floresville Homes
- Disconnected duct joints under pier-and-beam homes. Caliche soil shifts with moisture changes across the seasons. The ground moves, the crawlspace moves, and duct joints pull apart. Heated air dumps into the crawlspace instead of the living room, and the furnace runs constantly without warming anything.
- Cracked heat exchangers in undersized original furnaces. A 1970s or 1980s furnace that was sized when the house had less insulation now runs long cycles. That sustained heat stress cracks the heat exchanger. If you smell a faint metallic odor when the burners light, shut the system down and call us. Carbon monoxide is a real risk.
- Weak blower motor capacitors. A capacitor rated at 5 MFD that is reading 3.1 MFD still spins the blower, but too slowly. Airflow drops, the heat exchanger overheats, and the limit switch trips. The symptom looks like a furnace that “runs but won’t stay lit.” The fix is often under $350.
- Nuisance trips from older electrical panels. Many Floresville homes built before the mid-1980s do not have a dedicated breaker for the blower motor. Modern ECM blowers draw differently than the old PSC motors the panel was designed for, and that can trip breakers on the coldest nights when the system works hardest.

Last winter we got called to a 1980s brick veneer home off Sutherland Springs Road where the furnace would light but blow lukewarm. Our tech found the blower motor capacitor reading 3.1 microfarads on a 5 MFD rating, weak enough to starve the heat exchanger of airflow. After a capacitor swap and a static pressure check, the supply temps jumped 22°F and the limit switch stopped tripping. That is the kind of diagnosis you get when someone puts a meter on the component instead of guessing.
Here is what a generic furnace repair page will not tell you about Floresville: your problem is often not the furnace at all. It is the crawlspace. The caliche soil under this part of Wilson County expands and contracts with rainfall and drought. In older pier-and-beam homes, that movement separates duct joints under the house. A “furnace not heating” call in January is frequently a disconnected return pulling cold crawlspace air into the system, not a failed heat exchanger. We find it, we seal it, and the furnace you thought was dead is fine. That is the difference between a company that works in Floresville and one that just lists it on a service area page.

FAQs About Furnace Repair in Floresville
In Floresville, the most common cause is a disconnected or leaking duct joint under a pier-and-beam home. The caliche soil shifts, the duct separates, and the furnace pulls cold crawlspace air into the return side, diluting the heated supply air. The burners are working; the delivery system is broken. Other causes include a weak blower motor capacitor that cannot push enough air across the heat exchanger. Both are diagnosable in one visit. Call (361) 470-8872 and we will put a meter on it.
It depends on what failed and what the system is. A cracked heat exchanger in a 25-year-old furnace is a replace situation, not a repair, because the part cost and the carbon monoxide risk both argue against patching it. But a weak capacitor, a dirty flame sensor, or a failing ignitor on the same unit is often a $150 – $350 repair that buys you several more seasons. We give you the diagnosis, the repair quote, and the replacement quote side by side, and we do not push you either direction. The decision is yours, made with a written number in front of you.
Yes, and in Floresville it matters more than in drier climates. The high humidity and the long summer cooling season put strain on the same blower motor, ductwork, and electrical connections that the furnace uses. A tune-up checks the blower capacitor, the static pressure, the condensate handling, and the duct connections under the house. Those are the components most likely to fail during either season. $80 – $200 once a year is less than one emergency call.
Short-cycling, where the furnace turns on, runs a few minutes, then shuts off and repeats, is usually the limit switch doing its job. In Floresville brick veneer homes, especially those with original ductwork, the common cause is low airflow: a weak blower capacitor, a dirty filter, closed supply vents, or collapsed duct sections under the house. The heat exchanger overheats, the limit switch trips, and the cycle repeats. A static pressure test is the fastest way to identify the airflow problem, and it costs $150 – $300.
Sometimes, yes. Homes in Floresville built before the mid-1980s often have panels without a dedicated breaker for the blower motor. Older PSC motors drew power differently than modern ECM blowers, and a new furnace can nuisance-trip an already loaded circuit on cold nights. We check the panel load and the motor draw before install, and if the panel needs attention, we tell you in writing before the furnace goes in, not after. No surprise electrical work, no code violations left for you to discover later.
