Most HVAC maintenance guides are written for four-season climates where systems get a break in mild weather. That's not South Broward. In Pompano Beach, your AC is arguably more critical infrastructure than your water heater. This guide is built specifically for our climate.
Pre-Summer Check (March–April)
This is the most important maintenance window. Before temperatures climb into the 90s, confirm your system is ready.
- Schedule a professional tune-up — techs are fully booked in June, available now
- Replace the air filter
- Clear the condensate drain line with a cup of diluted bleach
- Test the system at multiple thermostat settings
- Check the condenser unit for winter debris accumulation
- Verify thermostat batteries and calibration
Peak Summer (May–September)
Your system is working at maximum load. Monthly attention prevents failures during the worst possible time.
- Check filter every 30 days — replace if gray
- Inspect the condensate drain pan weekly — standing water means a clog
- Listen for new noises after heat waves — thermal stress can loosen components
- Keep vents clear — furniture placed over return air registers kills efficiency
- Use ceiling fans to reduce thermostat load (fans cool people, not rooms — turn them off when you leave)
Hurricane Season Considerations (June–November)
South Florida HVAC systems face specific storm risks.
- Before a storm: Turn the system off — power surges during storms are a leading cause of compressor failure
- During: Never run the system — flying debris can impact the condenser fan blades
- After: Walk around the outdoor unit before restarting — check for dents, debris inside the unit, and level ground beneath
- If the unit was flooded, do not restart until a technician inspects it
Fall Transition (October–November)
Temperatures drop (somewhat). Humidity stays high. This is a good time for a secondary inspection.
- Professional coil cleaning if not done in spring
- Check refrigerant level — the shoulder season is the right time to address a slow leak
- Inspect insulation on refrigerant lines — South Florida sun degrades it over time
- Test heat strips if your system has them — occasional cold nights do happen
Year-Round Habits
- Set thermostat to 78°F or above when home
- Keep interior doors open to allow airflow
- Don't close vents in unused rooms — it raises system pressure
- Check that outdoor unit hasn't settled or tilted — affects refrigerant oil return
When to Call a Professional
Self-maintenance covers a lot, but these situations require a licensed technician:
- Any refrigerant issue (EPA regulations, safety)
- Electrical repairs inside the air handler or condenser unit
- Coil cleaning (improper cleaning damages coil fins)
- Anything you're unsure about — a $79 diagnostic visit is always cheaper than a compressor replacement
