Signs Your AC Needs Emergency Repair

  • The AC is blowing warm air, or not running at all, on a hot day
  • You smell burning or see smoke at a vent or the outdoor unit
  • The breaker trips every time the AC starts
  • Water is leaking from the indoor unit or through the ceiling
  • Ice on the refrigerant lines or the indoor coil
  • Grinding, banging or screeching from either unit
  • The outdoor unit hums but the fan won’t spin

Is a Broken AC an Emergency?

It is when the house is heating up and someone at home can’t handle the heat, or when the problem is electrical or leaking. Babies, older adults, anyone with a health condition and pets are most at risk in a hot house. If your AC quits on a summer afternoon in San Antonio, don’t wait until morning.

If the house is still comfortable and the system just isn’t keeping up, a regular visit is usually fine. See AC repair.

What Should I Do While I Wait for a Technician?

  1. Turn the system off at the thermostat if you smell burning, see ice or have water leaking.
  2. Check the breaker once. If it trips again, leave it off.
  3. Check the air filter. A clogged filter can freeze the coil.
  4. If water is pooling at the indoor unit, the drain line is likely clogged. Turn the AC off and call.
  5. Close the blinds, run ceiling fans and move kids, older family members and pets to the coolest room.

If anyone shows signs of heat illness, call 911.

What Usually Causes an AC Emergency in San Antonio?

  • Failed capacitor or contactor. The most common no-cool call in summer. The AC hums, clicks or won’t start.
  • Frozen coil. Low airflow or low refrigerant. You get warm air and ice on the lines.
  • Clogged condensate drain. Water leaks, or a safety switch shuts the AC off. Our humidity makes this a regular one.
  • Electrical problems. Tripping breakers, burned wires or a burning smell.
  • Refrigerant leak. The system runs but never cools the house down.
  • Failed blower or fan motor. Air stops moving, or the outdoor unit overheats and shuts off.
  • Compressor failure. The least common and most expensive. If repair doesn’t make sense, we’ll tell you straight and walk you through AC replacement.

What Happens When You Call?

  1. Call (210) 404-7723 or book online and tell us what the system is doing.
  2. We send the soonest available technician, same day in most cases.
  3. The technician finds the problem and explains your options before doing any work.
  4. We make the repair, test the system and make sure the house is cooling before we leave.

Do You Handle Heating Emergencies Too?

Yes. The same 24/7 service covers gas furnaces, heat pumps and electric heat. If the heat goes out on a freeze night, see heater repair.

Where Do You Offer Emergency AC Repair?

All of San Antonio and the surrounding area, including Alamo Heights, Stone Oak, Schertz, Universal City, New Braunfels, Alamo Ranch, Boerne, Helotes, Castroville, Bulverde, Fair Oaks Ranch and Shavano Park.

How Do I Avoid an AC Emergency Next Summer?

Most emergency calls trace back to a part that was already wearing out. A spring tune-up catches weak capacitors, dirty coils and clogged drain lines before the heat does. See AC maintenance or the Air Care Membership, which covers both yearly tune-ups.

Emergency AC Repair FAQs

Do You Offer 24 Hour AC Repair in San Antonio?

Yes. Air & Drain Works answers emergency AC calls 24/7, including nights, weekends and holidays.

How Fast Can You Get to My House?

In most cases, the same day. When you call, we’ll give you the soonest time we have for your area.

Do You Repair All AC Brands?

Yes. We repair all brands of central air conditioners and heat pumps.

Should I Keep Running My AC If It’s Frozen?

No. Turn it off at the thermostat and let the ice melt. Running a frozen system can damage the compressor. Check the air filter, then call us.

Can a Clogged Drain Line Shut Off My AC?

Yes. Many indoor units have a safety switch that turns the AC off when the drain line backs up. It protects your ceiling, but the house stops cooling until the drain is cleared.
