You don't need to be an HVAC technician to keep your system healthy. These owner-maintained tasks take minimal time and prevent the majority of common breakdowns we see.
Every Month
Check and replace the air filter. In Florida, 30–45 days is the realistic interval for most homes. Hold it up to light — if you can't see through it, replace it.
Clear debris around the outdoor unit. Leaves, grass clippings, and dirt reduce airflow through the condenser coil. Keep 2 feet of clearance on all sides.
Check the condensate drain pan. Look for standing water under your air handler. A small amount is normal; a puddle means the drain is clogging.
Every Quarter
Pour a cup of diluted bleach into the condensate drain. This prevents algae buildup — the #1 cause of drain clogs in Florida's humidity.
Inspect ductwork where visible. Look for disconnected sections, tears, or debris. Leaky ducts can waste 20–30% of conditioned air.
Test your thermostat. Set it 5°F below room temperature and make sure the system responds within a few minutes.
Every Year (or hire a pro)
Professional coil cleaning. The evaporator and condenser coils collect grime that restricts efficiency. This requires specialized cleaners and tools — not a garden hose.
Refrigerant level check. Technicians use gauges to verify charge is within spec. Low refrigerant almost always means a leak that should be found and repaired.
Electrical connection inspection. Loose connections arc, generate heat, and cause component failures. A technician tightens terminals and checks amperage draw.
Blower wheel cleaning. A dirty blower restricts airflow and makes the motor work harder. Cleaning it is like clearing a clogged artery.
The One Thing That Pays for Itself
If you do nothing else, join a maintenance plan. The annual tune-ups prevent the expensive failures — and our VIP members get priority scheduling when their neighbor's AC goes out on the same 95°F July afternoon.
