Based in Castroville, Not 25 Miles Away

Most companies ranking for emergency AC service in this area operate out of San Antonio, roughly 25 miles east along US-90. When your house is heating up fast, that distance matters. A/C Technical Services is physically located in Castroville, which can mean shorter drive times and faster arrivals for residents across Medina County, including LaCoste and Rio Medina.

On-time service isn’t a slogan for us. It’s a commitment we’ve kept for over 34 years, serving Castroville and the surrounding communities. We believe in being there on time for our customers.

34 Years in Castroville. 52 Years of Industry Experience.

A/C Technical Services was founded in 1991 by Gregg and Carol Zinsmeyer. Gregg has 52 years of experience in the HVAC industry, having grown up in the air conditioning business. That depth of knowledge shows up in how we diagnose problems, how we treat customers, and how we stand behind our work.

Every repair is backed by a warranty, and our team holds ABC Contractor Accreditation with recertification in 2021, 2022, and 2023. Gregg remains active in local and national HVAC industry organizations, so our technicians work from current standards and methods. Customers consistently describe us as fast, professional, honest, and reliable, and we take that seriously on every call.

Available Around the Clock for Emergency Air Conditioning Repair

We’re available days, nights, and weekends for Castroville residents who can’t wait for a next-business-day appointment. Same-day service options are available, and our bilingual team helps support clear communication with every customer. Free estimates mean you’ll know the cost before any work begins. Savings opportunities may also be available on our website.

Call A/C Technical Services at (210) 791-8172 to reach Castroville’s local emergency air conditioning company. We’re here around the clock.

Signs Your AC Needs an Emergency Call Right Now

Some AC problems can wait for a scheduled appointment. These can’t:

No cold air at all during extreme heat, when indoor temperatures can become dangerous within hours
Short-cycling, where the system turns on and off repeatedly without completing a full cooling cycle
Ice or frost on the indoor unit or refrigerant lines, a common sign of frozen evaporator coils or restricted airflow
Burning or electrical odor coming from any part of the system
Loud banging, grinding, or screeching from the outdoor condenser, often signaling a failing compressor or motor
Tripping circuit breakers each time the AC runs, indicating an electrical fault that shouldn’t be repeatedly reset
Water pooling around the indoor air handler, typically caused by a blocked condensate drain
Hissing or bubbling sounds near the refrigerant lines, pointing to a possible refrigerant leak
A thermostat that won’t respond or can’t hold the set temperature despite the system running

If any of these describe what you’re seeing, call now. A wait-and-see approach isn’t worth the risk in South Texas heat.

What to Expect When You Call for Emergency AC Service

We keep the process straightforward so you’re not left guessing at a stressful moment.

Dispatch
When you call, we get a technician moving toward your location promptly. Our Castroville base means we’re not navigating metro traffic to reach you.

Diagnosis
On arrival, your technician performs a full diagnostic to identify the root cause, whether that’s a failed capacitor, a refrigerant leak, a compressor issue, or something else entirely.

Clear Quote Before Any Work
You’ll receive an explanation of what failed and why, along with a quote, before we touch anything. No surprises on the invoice.

Repair & System Test
We complete the repair and run the system through a full test before we leave. If a residential AC system is beyond repair, we can present honest replacement options without pressure.

Getting there on time and getting it right the first time is how we’ve operated since 1991.
