Top 5 Signs Your Air Conditioner Is About to Break Down

Know the Warning Signs Before It’s Too Late

When summer heat hits Lancaster and Los Angeles, the last thing you need is a broken air conditioner. Unfortunately, many AC units don’t fail overnight — they give warning signs first. If you catch these early, you can avoid an emergency breakdown and a sky-high repair bill.

Here are the top 5 signs your AC is in trouble:

1. Warm Air Instead of Cool Breeze
If your system is blowing air but it’s not cold, it could be a sign of low refrigerant, a compressor issue, or blocked airflow. Don’t ignore it — this is one of the first signs of AC failure.

2. Weird Noises You’ve Never Heard Before
Rattling, buzzing, grinding, or banging sounds usually mean something is loose or damaged inside the unit. A fan, belt, or motor might be on its way out.

3. Sudden Spikes in Your Energy Bill
If your utility bill has gone up but your usage hasn’t, your AC may be working overtime due to internal wear, dirty filters, or refrigerant leaks.

4. Strange Smells Coming From the Vents
Musty odors could indicate mold in your ducts. A burning smell might mean electrical issues. Both are signs your AC needs immediate inspection.

5. Frequent Cycling or Constant Running
Short cycling or nonstop operation often points to thermostat problems, a failing compressor, or improper sizing. This also shortens your unit’s lifespan.
