Florida's climate is one of the hardest on HVAC systems in the country. Your AC doesn't get a break. It runs 8 to 10 months out of the year, pulling double duty on both cooling and dehumidification. That workload means Florida systems age faster and need more frequent attention than systems in moderate climates.
Here's what we recommend for a Tampa homeowner.
The short answer: twice a year
Have your HVAC system professionally serviced twice per year:
- Spring (March to April): Before the heavy cooling season. This is your AC tune-up. The technician checks refrigerant levels, cleans the coils, tests electrical components, and makes sure the system is ready for five straight months of near-constant operation.
- Fall (October to November): Before heating season. Tampa winters are mild, but your heat pump or furnace still needs an annual check. This visit focuses on heating mode: checking the reversing valve (for heat pumps), testing the heat strips, and inspecting the blower motor.
What's included in a professional tune-up
A proper HVAC tune-up isn't just "checking the filter." Here's what a quality technician does during a maintenance visit:
Outdoor unit (condenser): - Clean condenser coils (remove dirt, debris, grass clippings) - Check refrigerant levels and test for leaks - Inspect contactor for pitting or arcing - Test capacitor with a multimeter - Check fan motor amp draw - Inspect wiring connections for tightness and corrosion - Clear debris from around the unit
Indoor unit (air handler): - Check evaporator coil condition - Clear and treat the condensate drain line - Test the blower motor and amp draw - Check the air filter and recommend replacement schedule - Inspect ductwork connections at the plenum - Test the thermostat calibration - Measure supply and return air temperature differential
System performance: - Measure airflow across the evaporator - Check the temperature split (should be 15 to 20 degrees between supply and return) - Record system pressures for baseline comparison - Note any components that are showing wear but haven't failed yet
A thorough visit takes 45 to 75 minutes per system.
What you should do monthly
Between professional visits, there are a few things you can handle yourself:
Change your air filter. In Tampa, change it every 30 days during peak cooling season (May through September) and every 60 to 90 days during cooler months. A dirty filter is the number-one cause of preventable AC problems. It restricts airflow, causes the evaporator to freeze, drives up your electric bill, and shortens the life of your blower motor.
Keep the outdoor unit clear. Maintain at least 24 inches of clearance around all sides of your condenser. Trim back landscaping, remove leaves, and don't stack anything against the unit.
Check the condensate drain. If you can see your condensate drain line (usually a PVC pipe near your outdoor unit), make sure water is flowing freely when the system is running. If it's dry, the line may be clogged.
Why skipping maintenance costs more
We hear this often: "My AC is working fine, why would I pay for maintenance?" Here's why:
A neglected AC system loses about 5% of its efficiency per year. After five years without maintenance, a system that started at 16 SEER is effectively running at 12 to 13 SEER. On a Tampa summer electric bill, that efficiency drop can add $40 to $80 per month.
More importantly, most AC breakdowns are preventable. A capacitor that tests weak during a tune-up costs $25 to replace proactively. The same capacitor failing on a 97-degree Saturday afternoon costs $150 to $250 for an emergency call and leaves your family in the heat for hours.
Manufacturer warranties often require proof of annual maintenance. Skip the tune-ups, and you may void the parts warranty on your $8,000 system.
Maintenance agreements
We offer annual maintenance plans that include both the spring and fall visits at a discounted rate, plus priority scheduling and a discount on any repairs needed throughout the year. It's the best way to protect your investment and avoid surprise breakdowns.
