Preparing Your HVAC System for Summer: A Peninsula Checklist

DIY Spring Checklist

Week Before You Need AC:

• Replace the air filter - Start the season fresh
• Clear outdoor unit - Remove leaves, debris, trim plants
• Clean supply vents - Vacuum dust from registers
• Check thermostat - Replace batteries, test cooling mode
• Inspect visible ductwork - Look for obvious damage

Test Your System:

• Set thermostat to cooling mode
• Lower temperature 5 degrees below current room temp
• Wait 10-15 minutes
• Feel air at vents - should be noticeably cool
• Listen for unusual sounds

When to Call a Professional

Schedule maintenance if:

• AC hasn't been serviced in over a year
• Last summer you noticed issues
• System is over 10 years old
• You hear unusual sounds during testing

Peninsula Summer Insights

Our summers are generally mild compared to inland California, but we do get heat spikes. Homes in Palo Alto, Mountain View, and inland areas can see 90°+ days that really test your AC.

Schedule Early

Don't wait until the first heat wave. HVAC companies get swamped in June and July. Schedule your spring maintenance in April or May for the best availability.
