Your AC is one of the most important systems in your home — especially in Kendall and surrounding areas, where heat and humidity are part of everyday life. And when something goes wrong, it usually gives you small signs before the real damage shows up.

Here are 7 warning signs your AC needs urgent repair. Ignoring them can lead to higher bills, bigger problems, or a full system breakdown.

1. Your AC is running, but not cooling

If the air feels warm, weak, or inconsistent, something is wrong. The problem could be:

• Low refrigerant

• Blocked airflow

• A failing compressor

Don’t wait — the longer the system struggles, the more expensive the repair becomes.

2. Water leaking around the unit

A little condensation is normal. But puddles, dripping, or water near the indoor unit is not.

This usually means:

• A clogged drain line

• A dirty coil

• A broken or stuck flow switch (which may shut off your AC)

Left untreated, water leaks can damage walls, ceilings, and floors.

3. Strange noises — buzzing, banging, or rattling

Your AC should sound like a quiet hum. If you hear new or unusual sounds, it’s your system asking for help.

These noises may signal:

• Loose parts

• A failing fan motor

• Electrical problems

The fix is usually simple if caught early.

4. Bad smells coming from the vents

Burning, moldy, or chemical smells are red flags, they may indicate:

• Mold in the system

• A dirty drain pan

• Electrical or overheating issues

If it smells burnt — turn off the AC immediately.

5. The AC keeps turning on and off (short cycling)

This means the system can’t complete a full cooling cycle, here you have some possible causes:

• Refrigerant issues

• Dirty coils

• A failing thermostat

Short cycling wastes energy AND shortens your AC’s lifespan.

6. Higher electricity bills for no clear reason

If your bill jumps but your routine hasn’t changed, your AC is working too hard, this usually happens when:

• Filters are clogged

• Coils are dirty

• A part is failing and draining energy

A small repair today can prevent a large bill tomorrow.

7. The AC shuts off by itself

Many people think the AC is “broken,” but sometimes it’s actually protecting you. Most systems in Florida have a flow switch — a safety device that shuts down the AC when too much water builds up inside. This prevents leaks and expensive damage.

If your AC keeps shutting off, you likely need a simple drain cleaning or maintenance check.
