My AC Stopped Working in Greer, SC – What Do I Do First?

my AC stopped working what do I do first?

It always seems to happen at the worst possible time.

You’re relaxing after a long day, the South Carolina heat is doing its thing, and suddenly…the house starts feeling warmer. You walk over to the thermostat, and sure enough… your air conditioner stopped working.

Before you panic (or start shopping for a window unit), take a deep breath. There are a few simple things you can check before calling in the pros.

Here’s what the team at Waldrop Plumbing Air Electric recommends.


1. Check Your Thermostat

It sounds obvious, but you’d be surprised how often this solves the problem.

Make sure:

  • It’s set to Cool
  • The temperature is set lower than the current room temperature
  • The batteries aren’t dead (if your thermostat uses them)

If you recently experienced a power outage, your thermostat may have reset itself.


2. Check Your Breaker Panel

Sometimes your air conditioner trips a breaker.

Head to your electrical panel and look for any breakers that are sitting halfway between ON and OFF.

If you find one:

  • Turn it completely OFF.
  • Then switch it back ON.

If it trips again immediately, stop there. Repeatedly resetting breakers can be dangerous and usually means there’s a larger electrical problem that needs professional attention.


3. Look at Your Air Filter

A clogged air filter can restrict airflow enough to cause your system to freeze up or even shut down.

If your filter looks dirty enough to write your name in it…

It’s time for a new one.

Replacing filters every 1–3 months helps your system run more efficiently and can prevent many common AC problems.

4. Check Your Outdoor Unit

Walk outside and take a look at your condenser.

Ask yourself:

  • Is it covered in leaves or grass?
  • Are shrubs blocking airflow?
  • Is it making unusual noises?
  • Is the fan spinning?

If it’s packed with debris, gently clear away anything blocking airflow.

Just don’t stick your hands inside the unit.


5. Is Your AC Frozen?

If you notice ice on the refrigerant lines or the outdoor unit, your system may have frozen.

Turn the thermostat from Cool to Off, then switch the fan to On.

This helps thaw the ice.

Don’t restart cooling until everything has completely melted, or you could damage the compressor.


6. Listen for Strange Sounds

Your air conditioner is trying to tell you something.

Different noises often point to different problems:

  • Buzzing could mean electrical issues.
  • Grinding may indicate motor problems.
  • Clicking could be a failing relay.
  • Hissing may signal a refrigerant leak.

If your AC sounds like it’s auditioning for a horror movie…

It’s probably time to call a technician.


7. Don’t Ignore Burning Smells

If you smell something burning, turn your system off immediately.

Electrical odors can indicate overheating wires, failing motors, or other safety hazards.

This isn’t a DIY situation.


When Should You Call an HVAC Professional?

If you’ve checked the basics and your AC still isn’t cooling, it’s time to bring in the experts.

Common issues we diagnose every summer in Greer include:

  • Failed capacitors
  • Refrigerant leaks
  • Frozen evaporator coils
  • Blown fuses
  • Faulty contactors
  • Clogged condensate drains
  • Worn blower motors
  • Compressor problems

Most homeowners can’t safely diagnose these issues without specialized tools.


How to Prevent Your AC from Stopping Again

The best repair is the one you never need.

A few simple habits go a long way:

  • Change your air filter regularly.
  • Keep the outdoor unit clear.
  • Schedule annual AC maintenance.
  • Address unusual noises early.
  • Don’t ignore weak airflow or longer cooling cycles.

Routine maintenance often catches small problems before they become expensive breakdowns.
