5 Signs Your AC Needs Repair Before Summer Hits

As temperatures start climbing in Cedar Park, your air conditioner becomes your best friend. But how do you know if it’s ready for another brutal Texas summer? Here are five warning signs that your AC needs professional attention.

1. Warm Air Coming from Vents

If your AC is blowing warm or lukewarm air instead of cold, something’s wrong. This could indicate:

  • Low refrigerant levels (possibly from a leak)
  • A failing compressor
  • Restricted airflow from dirty filters or ductwork issues

Don’t ignore this sign—running an AC with low refrigerant can cause permanent compressor damage.

2. Unusual Sounds

Your AC should run relatively quietly. New or unusual sounds are a red flag:

  • Grinding or scraping: Metal-on-metal contact, possibly a motor bearing failure
  • Squealing: Belt issues or motor problems
  • Clicking: Electrical component failures
  • Banging: Loose or broken internal components

Turn off your system and call a technician if you hear these sounds.

3. Weak Airflow

If the air coming from your vents feels weak, you might have:

  • Clogged air filters (check these monthly!)
  • Blocked or leaking ductwork
  • A failing blower motor
  • Frozen evaporator coils

Start by replacing your filter. If that doesn’t help, it’s time for a professional inspection.

4. High Humidity Indoors

Your AC does more than cool—it also removes humidity. If your home feels sticky or clammy even with the AC running, your system may need:

  • Refrigerant recharge
  • Evaporator coil cleaning
  • Proper sizing evaluation (an oversized unit can short-cycle)

High indoor humidity also promotes mold growth, making this a health concern.

5. Rising Energy Bills

If your electric bills are climbing but your usage hasn’t changed, your AC is working harder than it should. Common causes include:

  • Dirty coils reducing efficiency
  • Refrigerant leaks
  • Aging equipment (systems over 10 years old lose efficiency)
  • Thermostat malfunctions

A tune-up can often restore efficiency. For older systems, replacement might be more cost-effective.

Don’t Wait for a Breakdown

The worst time to discover your AC needs repair is during a 100°F Texas heat wave. Schedule a pre-summer inspection now to catch problems early.
