Most AC repairs in Kirby run between $150 and $650, and we can usually have a technician at your door the same day you call.

Why Brandt HVAC Co San Antonio Is Kirby’s Preferred AC Repair Company

Styles & brands we work with






AC Service in Kirby
AC Service in Kirby means something a little different depending on the age of your house. For a newer subdivision home west of Foster Road, service usually means a seasonal checkup, a capacitor replacement, or a refrigerant top-up on a builder-grade unit that was never quite dialed in. For an older ranch house east of Binz-Engleman, service often means chasing down airflow problems caused by original 4-inch duct runs that were never designed for a modern AC load. Either way, we start with a full diagnostic, write down the findings, and quote you a firm number before any repair begins.
Seasonal Maintenance and Early Warning Repairs
Kirby’s heat means your system runs hard from April through October. A capacitor that is about to fail will often show signs weeks before it dies: the outdoor unit hums but does not start, or the fan spins slower than it should. Catching these things during a routine service can prevent a no-cool emergency on the hottest day of the year. Most Kirby homeowners spend $80 to $200 for a tune-up that includes checking refrigerant pressures, testing capacitors, and measuring static pressure across the coil.
Refrigerant and Airflow Diagnostics
When a Kirby home is not cooling evenly, the problem is rarely as simple as “low Freon.” We check static pressure first. Many older ranch homes here have ducts that cannot move enough air for the unit sitting outside, which causes coils to freeze and compressors to strain. A refrigerant recharge, meaning refilling the fluid that moves heat out of your home, runs $150 to $450 depending on the volume and system type. If the issue is low airflow rather than low refrigerant, the fix is often a duct adjustment or blower speed change – usually under $300.
AC Unit Repair in Kirby
AC Unit Repair in Kirby covers the outdoor condenser, the indoor evaporator coil, and the blower motor that pushes conditioned air through your ducts. In the tightly-packed ranch homes that dominate Kirby’s original town grid, we see a lot of condenser units crammed into small side yards with poor clearance, which shortens the life of fan motors and compressors. In the newer subdivisions, we see the opposite: equipment sized by rule of thumb rather than a real load calculation, leaving the unit undersized for an August heat wave.
Condenser and Coil Repairs
A fan motor that seizes on a Bryant or Goodman condenser will shut the whole system down. Depending on the motor type and access, you are looking at $200 to $480 in Kirby. Evaporator coil repairs trend higher when the coil is frozen repeatedly due to duct problems, which is why we never just thaw it and leave. We find out why it froze. Most AC unit repairs in Kirby land between $150 and $650, parts and labor included, always quoted in writing before we start.
The Exact Quote Promise
Every AC unit repair in Kirby begins with a written price. Not an estimate range, not a ballpark, not a “well, depends on what we find.” A written price. You see it, you agree to it, then we work. That is how Devin Marlowe runs this company, and it is why Kirby homeowners answer the door when our techs arrive.
Trusted Brands We Service in Kirby
We service all major residential HVAC brands, and we keep common parts stocked for the brands Kirby homeowners actually have. That means Rheem and York condensers in the older ranch homes, and Daikin and Bryant builder-grade units in the neighborhoods that went up in the last ten years. Having the right part on the truck means we finish most repairs in a single visit instead of making you wait while something ships. If your system is under manufacturer warranty, we handle the paperwork and only charge for labor and non-covered parts.
Common AC Repair Problems We See in Kirby Homes
- Frozen evaporator coils in older ranch homes. The original 4-inch ducts choke airflow, the attic turns into an oven on 100°F days, and the coil freezes solid. We thaw the coil, then fix the airflow problem so it does not happen again the following week.
- Builder-grade systems in newer subdivisions that are undersized for the load. Many new-construction AC units in Kirby were sized by rule of thumb, not a real Manual J calculation. The result is a system that cannot hold 72°F on a 100°F day, regardless of what the thermostat says.
- Blower motors that burn out early. Unbalanced ductwork drives high static pressure, which makes the blower motor work harder than it should. We see blower failures in Kirby homes that are only four or five years old, which should not happen.
- Capacitors that fail on the first really hot day. A capacitor is a small, inexpensive component that gives the compressor and fan motor the kick they need to start. When it fails on a 98°F afternoon, the whole system goes down. We replace these for $150 to $250, and we keep common sizes stocked for Kirby service calls.

Why Some Kirby Homes Freeze Coils While Others Do Not
The single biggest difference between a comfortable Kirby home and one with constant AC problems is ductwork, not equipment. Many 1950s-to-70s ranch homes in Kirby still run their original 4-inch duct runs, so on 100°F days the attic becomes an oven that freezes evaporator coils. We see this pattern almost daily on the east side but rarely in the newer subdivisions to the west. If your home is east of Binz-Engleman and your coil keeps icing up, the problem is almost certainly in the ducts, not the refrigerant.
Last July we got called to a 1960s ranch off Ackerman Road where the AC would run for an hour then blow warm. Our tech found a Goodman condenser with a weak capacitor and a frozen evaporator coil caused by the home’s original 4-inch ducts choking airflow. We replaced the capacitor, thawed the coil, and corrected the refrigerant charge, then showed the homeowner how undersized ducts were driving static pressure through the roof. That is the kind of diagnosis you only get from a tech who has worked through a Kirby summer in an attic.
Builder-grade systems in Kirby’s newer subdivisions have the opposite problem. They are often sized by rule of thumb instead of a real Manual J load calculation, leaving them short on tonnage for August afternoons. The new homeowner skips warranty registration and discovers the compressor is not covered when it fails in year two. Then there is the first-summer surprise: hot master bedrooms, frozen coils, and blower motors that burn out early because the ducts were never balanced after construction. Our AC Repair team corrects what the builder’s installer left unfinished.

FAQs About AC Repair in Kirby
Most frozen coils in Kirby’s older ranch homes trace back to original 4-inch ductwork that cannot move enough air, causing the evaporator coil to drop below freezing and ice over. The attic temperatures on a 100°F day make it worse. The fix is typically a blower adjustment, duct modification, or both, not just adding refrigerant. Call (361) 470-8872 and we will find the real cause.
Yes, and it usually means the builder’s installer sized the unit by rule of thumb instead of a real load calculation. The first truly hot August exposes it. A Manual J calculation on your specific home will show whether the system is undersized, and we can quote a correction. Estimates are free.
Only if the equipment was registered with the manufacturer within the required window, usually 60 to 90 days after closing. We see many Kirby homeowners skip this step and discover too late that the compressor or coil is not covered. If you are not sure whether your system was registered, call us at (361) 470-8872 and we will help you check before you pay for a repair you may not need to pay for.
That is a balancing or duct-run problem, not an AC failure. A room at the end of a long duct run, or one with undersized supply branches, will never cool properly until airflow is corrected. We measure airflow at each register and give you a written quote for the fix. In Kirby’s ranch homes, this is one of the most common repairs we make after the first heat wave.
Check the thermostat setting and the circuit breaker first: a breaker tripped by a hard-starting compressor is common on Kirby’s hottest afternoons. If both are fine, the problem could be a failed capacitor, a seized fan motor, or low refrigerant. Do not keep running a system that blows warm air. That strains the compressor and turns a small repair into a big one. Call (361) 470-8872 and we will walk you through a quick check over the phone, then send a tech if needed.
If your AC is struggling in Kirby, TX, call (361) 470-8872 now. You will get a live person, a straight answer, and a written price before any work starts. If it is not done right, we make it right. That is the deal.
