Why Summer Prep Matters in the Bay Area

The Bay Area experiences significant temperature variation, with inland valleys like Livermore and San Ramon reaching 100°F while coastal cities stay cooler. This guide covers preparation for all microclimates.

Pre-Season AC Inspection Checklist

Start by replacing your air filter—a clogged filter reduces efficiency by up to 15%. Check your thermostat batteries, clear debris from outdoor units, and ensure vents aren't blocked by furniture.

Professional Tune-Up Benefits

Annual professional maintenance catches refrigerant leaks, worn belts, and electrical issues before they cause breakdowns during peak cooling season. Most tune-ups take 1-2 hours and cost $80-150.

Optimizing Efficiency for Hot Days

Use ceiling fans to circulate cool air. Set your thermostat to 78°F when home and 85°F when away. Close blinds on south-facing windows during afternoon hours.

When to Schedule Service

Book your summer tune-up in April or early May before HVAC companies enter their busy season. Last-minute service calls in July may have longer wait times.

Frequently Asked Questions

Quick answers to common questions

During heavy use, check your filter monthly and replace it every 1-2 months, or as needed if you have pets or allergies.

The DOE recommends 78°F when home. Each degree lower increases energy use by about 3%.
