Why San Antonio Homeowners Choose Aramendia Plumbing, Heating and Air

There are plenty of air conditioning companies in the San Antonio area. What sets us apart are named, defined commitments, not vague assurances. Our technicians hold ACE-certified status, which requires higher passing scores than standard HVAC certifications, annual re-certification to stay current with advances in equipment and technology, and training in ethical service practices. That standard applies to every service call, whether it’s a minor repair or a full system replacement.

Guarantees That Define the Terms

All work is backed by the Service Experts Guarantee. For installations, that means up to three repair attempts on any unresolved issue, with a comparable replacement if the problem still isn’t fixed, all within one year. For service calls, if the same issue returns within 30 days, we come back at no additional cost. These aren’t general promises. They’re defined terms you can hold us to.

What to Do When Your AC Isn’t Cooling

A few quick checks can help before you call. These steps won’t replace professional service, but they can give our technicians useful context when you do reach out.

First, confirm your thermostat is set to cool and the target temperature is below the current room temperature. A recent power outage or battery change can reset settings without you noticing. Next, check your air filter. A heavily coated filter can restrict airflow enough to affect cooling performance on an otherwise functional system.

If the indoor unit is running but you hear nothing from the outdoor unit, look from a safe distance for visible ice buildup on the lines or unit. If you see ice or notice any unusual odors, turn the system off and call a professional.

Repair, Replacement, & Ongoing AC Maintenance in San Antonio

We organize our air conditioning services into three areas: repair to restore existing equipment to safe, reliable operation; replacement when a system is older or has needed frequent repairs; and ongoing maintenance to reduce the chance of mid-season failures. Knowing which stage your system is in can clarify next steps and help keep costs predictable.

Regular AC maintenance supports both repair and replacement decisions. A seasonal tune-up includes cleaning, refrigerant and coil inspection, and checks that help your system run efficiently through long stretches of heat. Keeping coils clean, filters replaced, and critical components inspected reduces strain on the system and surfaces small concerns before they become larger repairs. This is especially important in a climate that pushes cooling equipment hard for months at a time.

Our Maintenance+ membership includes seasonal tune-ups, a 15% discount on services, and additional member benefits. Through 8/31/26, Maintenance+ members also receive a $0 diagnostic when a recommended repair is completed and paid at time of service. For homeowners who want to start with a single visit, a Precision Tune-Up is currently available at $99 (regularly $189).
