Your San Diego Maintenance Calendar
🌱 Spring
Service AC before peak heat
A tune-up now prevents a $400 emergency call in July when every HVAC tech is booked.
Test and balance pool water chemistry
Algae blooms in warm water fast — weekly testing all summer saves costly treatments.
Inspect roof before storm season
Gulf Coast and Southeast storms cause the most damage to roofs already weakened by UV.
Flush water heater and check anode rod
Hard water common in warm-climate cities accelerates sediment buildup.
☀️ Summer
Replace HVAC air filter monthly
AC runs 8–12 hours daily in summer — a clogged filter cuts efficiency by 15% and shortens the system's life.
Check exterior caulking for heat cracking
Extreme heat causes caulk to crack, letting moisture into walls.
Service irrigation system
Peak watering season — a broken head wastes hundreds of gallons and kills landscaping.
Clean AC condenser coils
Dirty coils make your AC work 30% harder — one of the highest-ROI maintenance tasks in warm climates.
🍂 Fall
Annual HVAC tune-up
Shoulder season is the best time — cheaper and available before heating demand kicks in.
Clean gutters and downspouts
Fall debris clogs gutters before rainy season, causing fascia rot and foundation water intrusion.
Test smoke and CO detectors
Required annually; battery replacement every 6–12 months.
Clean dryer vent
Leading cause of house fires — even more critical in dry, warm climates.
❄️ Winter
Flush and inspect water heater
Mild winters are still hard on water heaters — sediment buildup cuts efficiency 20–30%.
Clean refrigerator coils
Dusty coils in warm homes work harder — cleaning extends compressor life.
Deep clean kitchen exhaust and oven
Grease buildup is a fire hazard; winter is a good time for deep cleaning.
Inspect and test whole-home security system
Burglary rates rise during holiday seasons — confirm sensors and cameras are working.
