How do I know if my AC needs repair?

How can I improve my AC's energy efficiency?

Boosting your AC's energy efficiency can lead to significant savings. Consider these tips:
  • Regular maintenance:
    • Schedule professional tune-ups at least once a year to optimize performance.
  • Programmable thermostat:

  • Seal air leaks:
    • Caulk and weatherstrip windows and doors to reduce drafts.
  • Proper insulation:

How do I fix a frozen AC unit?

Follow these steps to thaw a frozen AC unit:1. **Turn off the cooling system:** Set the thermostat to 'off' to stop the cooling cycle and prevent further damage to the compressor.2. **Turn on the fan:** Set the thermostat's fan setting to 'on' or 'auto.' This circulates warmer air over the frozen coil, helping it thaw more quickly..3. **Find and address the underlying cause:** Inspect the air filter and clean or replace it if it's dirty. If the filter is clean, the problem might be more complex, such as a refrigerant leak.4. **Call an HVAC technician if the problem persists:** If the unit freezes up again after thawing, or if you suspect a refrigerant leak, contact a licensed service provider promptly for diagnosis and repair. Avoid using sharp objects or tools to remove ice.
