3 Signs Your AC Needs Repair – Before the Texas Heat Hits Hard

If you live in Central Texas, you know one thing for sure: summer doesn’t wait. Whether you’re in Austin, San Antonio, or anywhere in between, the heat hits hard—and fast. And the last thing you need is for your air conditioner to give up on you when temps push past 90°.

At Radiant Plumbing & Air Conditioning, we’ve been keeping homes cool and comfortable across the greater Austin and San Antonio areas for over two decades. When your AC isn’t working right, we’re the first call homeowners make—and the last call they’ll need.

Here are three warning signs your AC needs professional attention—before it breaks down in the middle of a heatwave.

1. Poor Airflow or Warm Air

If your vents are pushing out weak air—or worse, air that isn’t cool at all—you may be facing one of several common problems. It could be a clogged filter, failing compressor, ductwork blockage, or even low refrigerant. Whatever the cause, weak airflow is not just uncomfortable—it can overwork your system and lead to bigger issues down the line.

Pro tip: If some rooms are cool and others aren’t, it might be time for a full system checkup or airflow balancing.

2. Loud or Unusual Noises

Your AC should be quietly doing its job in the background—not announcing itself with squealing, banging, or grinding sounds. Strange noises often point to worn bearings, loose belts, or even motor failure. The longer you wait, the worse (and more expensive) the problem becomes.

If your AC is making noise, don’t ignore it. Let a licensed Radiant technician diagnose it early and save you from a full system breakdown.

3. Moisture or Leaks Around the Unit

A little condensation is normal—but excessive moisture, puddles, or active leaks around your indoor or outdoor AC unit are not. This could mean a refrigerant leak (which is hazardous), a clogged condensate drain, or even mold buildup in your system.

Leaks = damage, both to your system and your home. If you notice moisture where it shouldn’t be, it’s time to call in the pros.
