How to Prepare Your AC for Summer: Complete Checklist

Summer in South Bay can bring temperatures that make a working AC essential. Preparing your system before the heat arrives prevents uncomfortable breakdowns during peak season.

DIY Checklist

1. Change Your Air Filter A clean filter improves efficiency and air quality. Replace it now and mark your calendar for monthly checks during heavy use.

2. Clear Debris Around Outdoor Unit Remove leaves, grass clippings, and debris from around your condenser. Maintain at least 2 feet of clearance on all sides.

3. Check Your Thermostat Test that your thermostat is working correctly. Consider upgrading to a programmable or smart thermostat for better efficiency.

4. Inspect Visible Ductwork Look for obvious gaps, tears, or disconnections in accessible ductwork. Leaky ducts can waste 20-30% of cooled air.

5. Clean Supply Vents Vacuum dust from supply and return vents. Ensure furniture or drapes aren't blocking airflow.

Professional Tune-Up Recommended

While DIY maintenance helps, a professional tune-up catches issues you can't see:

• - Refrigerant level check
• Electrical connection inspection
• Coil cleaning
• Blower component check
• Full system safety inspection

When to Schedule

Schedule your tune-up in early spring before HVAC companies get busy. Waiting until June often means longer wait times and higher prices.

Warning Signs to Watch For

• During your preparation, note any of these issues for professional attention:
• Unusual sounds during startup
• Weak airflow from vents
• Strange odors when system runs
• Uneven cooling between rooms

A small investment in preparation now prevents emergency repairs during the hottest days of summer.
