AfterFast, Reliable AC Repair Across Houston
AC repair in Houston typically runs $150 – $650 and most calls are completed same-day when you reach us early. We’re Brandt HVAC, and our AC Repair team dispatches from our Houston office to homes across the metro, from the Heights down to Meyerland and out toward Channelview. When your system quits in August and the attic’s pushing 150°F, you need someone who knows Houston’s housing stock, not a dispatcher reading from a national script. Call (984) 538-9003 and a live person picks up, 24 hours a day.
Why Brandt HVAC Is Houston’s Preferred AC Repair Company
We’ve been part of the Threshold Group family since 2003, and every Brandt location is independently owned and operated by people who live where they work. In Houston, that means our technicians know the difference between a 1960s Gulfton slab ranch and a 1980s Katy tract home before they walk through your door.
Our customers here tell us the same thing: they chose us because we send a name, photo, and background-checked profile before anyone arrives. That’s the Threshold Verified standard. If someone shows up who you weren’t told to expect, that visit is on us. No exceptions.
Phones are answered by a live person, 24/7. Not a callback queue. Not an automated tree. A real person who can get a technician moving toward your neighborhood.
Every repair starts with a written price you see and approve before any work begins. Every repair also includes a written guarantee under our 365-Day Done Right Promise: if it fails, we return at no charge. No argument. No additional fee.
AC Not Blowing Cold Air in Houston
AC Not Blowing Cold Air is the call we run most often in Houston from May through September, and it’s rarely as simple as “add refrigerant.” Houston’s Gulf Coast dew points in the mid-70s°F mean your system is fighting latent moisture load that most U.S. markets never see. When the evaporator coil ices over from low refrigerant or a weak blower motor, that 140 – 155°F attic heat finishes the job fast. Most diagnostic and repair calls fall in our $150 – $650 range, with refrigerant recharges, capacitor replacements, and blower motor repairs at the lower end and compressor or major electrical work toward the higher end.
What We Check First
We start with refrigerant level and superheat measurement, then test blower motor amp draw and capacitor microfarads. In Houston’s older homes, we also measure static pressure across the evaporator because collapsed attic flex duct is so common it mimics a bad compressor. We’ve found brand-new condensers fighting original 1960s ductwork that was never replaced after Harvey.
When It’s Not the Refrigerant
Short cycling from an unbalanced single-zone system, a thermostat that’s lost calibration, or a contactor welded shut can all blow air without cooling. We check the whole chain, not just the obvious part. Our written price covers the diagnosis and the fix, spelled out before we start.
AC Service in Houston
AC Service in Houston means more than a quick filter swap and a glance at the condenser, which is why Houston AC Maintenance is something we take seriously. With our effective cooling season running March through November, Houston systems accumulate run-hours that make annual coil cleaning, drain line flushing, and refrigerant checks genuinely critical. A tune-up runs $80 – $200 and includes a written report of what we found, not a sales pitch. Our technicians aren’t paid on what they sell, so the recommendation you get is the one we’d make to our own families.
What the Visit Covers
We clean the condenser coils, flush the drain line with nitrogen, check refrigerant charge and superheat, test all electrical connections and capacitor values, and measure temperature split across the evaporator. In Houston’s unconditioned attics, we also inspect accessible ductwork for collapsed runs and delaminated liner.
Why Annual Service Matters Here
Nine months of continuous operation means capacitors degrade, contactors pit, and refrigerant leaks develop slowly enough that you don’t notice until August. Catching a weak capacitor in March beats a no-cool call on a Saturday night in July. The homeowner who schedules service now rarely needs emergency repair later.
Trusted Brands We Service in Houston
We repair and maintain all major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and our Houston Trane service team carries common parts on every truck. Our Houston technicians carry common capacitors, contactors, and refrigerants on their trucks, and we source parts locally for faster turnaround on specialty components. Whether it’s a 15-year-old Rheem in a Braeswood ranch or a newer Daikin mini-split in a Midtown renovation, we’ve worked on it. We don’t push brand switches unless your system is genuinely unrepairable or unsafe.
Common AC Repair Problems We See in Houston Homes
- Collapsed attic flex duct after Harvey-era emergency replacements. In Meyerland, Friendswood, and other flooded neighborhoods, outdoor condensers were replaced under emergency permits without ductwork inspection. We regularly find 2018-vintage equipment fighting original 1960s flex duct that was never swapped out.
- Iced evaporator coils from low refrigerant or weak blower motors. Houston’s extreme attic heat turns a minor refrigerant leak into a frozen coil fast, and the subsequent water damage can destroy ceilings below the air handler.
- Short cycling from single-zone systems on unbalanced two-story plans. A downstairs thermostat that satisfies too quickly leaves upstairs rooms hot, so the system kicks on again before the compressor has proper off-time. Capacitor failure often follows.
- Electrical panels that can’t handle modern compressor inrush current. Many Houston homes built before 1980 have panels or wiring that need attention before a like-for-like swap can even be considered safe.
Pricing for AC Repair in Houston, TX
Most AC repair calls in Houston fall between $150 and $650, with the final price depending on what failed and how accessible it is in your attic or crawl space. A capacitor replacement or refrigerant recharge sits at the lower end. Compressor replacement or major electrical work pushes toward the higher end. We give you a written price before any work starts, every single time. No exceptions. That price includes parts, labor, and our 365-Day Done Right Promise. If you’re comparing quotes, ask whether the other company’s price includes the guarantee and whether they’ll put it in writing before they touch your system. We also offer AC Repair in Houston tune-ups at $80 – $200, which often catch problems before they become emergency calls. Estimates are free. Call (984) 538-9003.

FAQs About AC Repair in Houston
It could be low refrigerant, but in Houston it’s just as often a weak capacitor, a failing blower motor, or collapsed attic ductwork that can’t move enough air across the evaporator coil. We test superheat and subcooling to confirm refrigerant status before adding any, because overcharging causes its own problems. Call (984) 538-9003 for a free diagnostic estimate.
Houston’s dew points in the mid-70s°F mean your system must dehumidify, not just cool, and an evaporator coil that cycles off too quickly never stays below dew point long enough to pull moisture from the air. Undersized ductwork, short cycling, or an oversized unit are common culprits in local homes. We measure indoor relative humidity and static pressure to find the real cause, not just the symptom.
Not necessarily. Many post-Harvey replacements in Meyerland and Friendswood got new condensers but kept original attic flex duct, so the equipment itself is fine but it’s fighting ductwork that should have been replaced. We inspect the full system before recommending replacement. A duct repair often restores performance for a fraction of the cost.
Yes. Attics in Houston routinely reach 140 – 155°F in summer, and air handlers operating in that environment work harder, draw more amperage, and fail faster than identical equipment in conditioned spaces. Annual service, including coil cleaning and electrical connection tightening, is genuinely preventive here, not upselling.
Most residential AC repairs in Houston run $150 – $650, depending on the component and accessibility. Capacitors and refrigerant recharges are at the lower end; compressor or electrical panel work is at the higher end. We provide a written, itemized price before any work begins, and that price includes our 365-Day Done Right Promise. Call (984) 538-9003 for a free estimate.
When your AC quits in Houston, you need more than a fast truck. You need someone who understands why your 1970s slab ranch with original attic ductwork behaves differently than a new build, and who’ll tell you the truth about whether a repair or a full system approach makes sense. We’re Brandt HVAC. Call (984) 538-9003. A live person answers, 24/7, and we’ll send you a name and photo before anyone knocks.
