In Texas, your air conditioner works hard almost every day. When it isn't cared for, dust and dirt build up, parts wear down, and your home can quickly get hot and uncomfortable.

That's why regular HVAC maintenance is so important. It helps your system last longer, use less energy, and stay ready when the heat hits.

At AC American Air, we've helped homeowners across Stone Oak, Bulverde, and Thousand Oaks keep their homes cool and comfortable for years. Our tune-ups are fast, affordable, and handled by trusted local technicians.

What We Check During Every Tune-Up

We follow a detailed maintenance checklist to make sure your system runs safely and efficiently:

  • Clean condenser and evaporator coils
  • Inspect and replace air filters
  • Check refrigerant levels and look for leaks
  • Tighten electrical connections
  • Lubricate moving parts
  • Test thermostat accuracy and settings
  • Verify airflow and system performance

Each visit usually takes about an hour, and you'll get a full report on your system's condition.

Why Maintenance Pays Off

Regular tune-ups can prevent up to 80% of system breakdowns. You'll also see:

  • Lower energy bills: A clean system doesn't have to work as hard.
  • Better air quality: Fresh filters mean cleaner indoor air.
  • Fewer surprises: Catching small issues early saves you from big repair bills later.

Even newer systems need annual service to stay covered under warranty β€” and to stay efficient during San Antonio's long summers.

When to Schedule Your Maintenance

The best time for an HVAC tune-up is spring or early fall, before extreme temperatures hit. If you haven't had one in over a year, now's the time.

We serve neighborhoods throughout Stone Oak, Bulverde, and Thousand Oaks, with flexible scheduling and friendly technicians.
