5 Signs Your Air Conditioner Needs Service Before Summer

The worst time to find out your air conditioner has a problem is during the first 90-degree day of summer — when every HVAC company in town is booked. A quick check now can save you a sweaty, expensive emergency.

1. Weak or warm airflow

If the air coming from your registers feels weak or isn't as cold as it used to be, something's off. It could be a clogged filter, a frozen coil, a duct leak, or low refrigerant. None of those fix themselves, and most get worse the harder the system works.

2. Strange sounds or smells

A healthy AC runs quietly. Banging, rattling, squealing, or screeching usually means a loose or failing component. Musty odors point to mold or moisture in the system, while a burning smell is an electrical issue that needs immediate attention.

3. Higher humidity indoors

Your AC's job isn't just cooling — it dehumidifies, too. If your home feels sticky even when the thermostat is satisfied, the system may be short-cycling or oversized, failing to pull enough moisture out of the air.

4. Rising utility bills

Compare this year's cooling bills to last year's. If usage and rates are similar but the cost is up, your system is working harder to deliver the same comfort. That's a sign of declining efficiency — often a dirty coil, low refrigerant, or an aging compressor.

5. Short cycling

If your AC turns on and off every few minutes, it's short-cycling. That strains the compressor, wastes energy, and shortens equipment life. Causes include an oversized unit, a dirty filter, a low refrigerant charge, or an electrical fault.

The fix is simple: schedule a spring tune-up. A professional inspection catches these issues early, keeps your warranty intact, and ensures your system is ready when the heat arrives.
