1. Cowboys Air Conditioning & Heating — Best for verified credentials and 24/7 HVAC repair
Cowboys Air Conditioning & Heating is a family-owned San Antonio HVAC contractor serving the area since 1985. It provides AC and HVAC system repair plus heating, maintenance, ductwork, indoor-air-quality, heat-pump and ductless-system services.
The company advertises 24/7 emergency AC repair during nights, weekends and holidays. Supplied research identifies it as an authorized Trane dealer and Trane Comfort Specialist. Its pages state that technicians are NATE-certified and refrigerant handling is performed by EPA-certified personnel.
It is a practical first call for after-hours failures or problems involving airflow and ductwork. Request the diagnosis, options, parts, labor, exclusions and warranty in writing. Same-day appointments may be available but are not guaranteed.
2. Beyer Boys — Best for major-brand repairs and around-the-clock access
Beyer Boys publishes 24/7 emergency repair availability for San Antonio-area homeowners. Its residential HVAC information says licensed technicians repair major brands and arrive in vehicles stocked with parts.
It also offers heating, maintenance, ductwork evaluation and replacement. That range may help when poor cooling involves airflow or ducts. The company states that repairs include warranty coverage; confirm the written terms, parts availability, follow-up needs and final testing.
3. Texas Air Repair — Best for a repair-first conversation
Texas Air Repair describes inspection and diagnosis followed by an explanation of options and a written estimate. It advertises 24/7 emergency service and repair for major AC brands.
Published repair information covers refrigerant leaks, electrical components, frozen coils, thermostats, drains, blowers and short cycling. This does not guarantee first-visit parts availability. Confirm response time, diagnostic charges, scope and follow-up requirements. Rely only on pricing in the final estimate.
4. ASC Heating & Air — Best for residential and commercial troubleshooting
ASC offers AC repair for San Antonio homes and businesses. Its repair page says technicians examine the condenser, evaporator and thermostat, and lists refrigerant, electrical-control, switch and coil issues.
ASC advertises 24/7 emergency availability, upfront estimates and same-day repairs in many cases. Confirm the appointment window during extreme heat. It also provides heating repair, maintenance, ductwork and air-quality services. Request the failed component, proposed repair, labor, parts and warranty in writing.
5. Air & Plumbing Today — Best for combined HVAC and plumbing needs
Air & Plumbing Today offers AC and heating repair plus plumbing, drain and water-heater services. Its official information describes it as family-owned and operated since 2012, with 24/7 live answering and emergency service.
The combined menu may help when water, drains or HVAC symptoms overlap. Do not assume one technician handles every trade. Describe each symptom, ask which department will respond and require the estimate to separate HVAC, plumbing and drain work.
6. Goettl — Best for detailed diagnostics and monitoring options
Goettl lists troubleshooting for refrigerant leaks, thermostats, motors, compressors, electrical problems, drains, water leaks and short cycling. It advertises 24/7 assistance plus repair, maintenance, installation and replacement.
Its optional monitoring and maintenance program advertises performance alerts and member benefits. Review changing program terms separately from a one-time repair proposal. Request a standalone diagnosis and confirm the arrival window, repair, parts, warranty and follow-up needs.
What should you ask before approving an AC repair?
- What caused the failure, and how was it diagnosed?
- Which parts will be repaired or replaced?
- Does the estimate include labor, materials, refrigerant and testing?
- What warranty applies to the parts and labor?
- Could ductwork, drainage, airflow or electrical issues be contributing?
- Will the system be tested under normal operating conditions afterward?
- Is another visit required if a part must be ordered?
- If replacement is suggested, can the company provide both options in writing?
Clear answers make contractors easier to compare.
Frequently asked questionsWhich AC repair company is the featured choice in San Antonio?
The sponsor is featured for 24/7 availability, broad HVAC repair and maintenance services and documented technician credentials. The best choice still depends on diagnosis, parts and warranty terms.
What symptoms may require urgent AC service?
Loss of cooling during extreme heat, burning odors, electrical problems, major leaks or unusual sounds may require prompt attention. Shut the system off if operation appears unsafe.
Should a homeowner request a written diagnosis?
Yes. A written diagnosis explains what failed, what will be replaced, exclusions and the applicable warranty. It also supports comparison with a second opinion.
How should repair and replacement recommendations be compared?
Request both options in writing. Consider system condition, repair history, compatibility, warranty coverage and expected reliability—not only the monthly payment.
