AC tune-up and maintenance in Tampa Bay

A system around the bay runs 3,000 hours or more a year in 76–78 % humidity. The things that fail in August (a clogged drain line, a dirty coil, a weak capacitor, a slow refrigerant leak) are the things a spring visit finds in May. Maintenance does not make a 15-year-old system new; it makes the summer predictable.

Call or send the form and get connected with an independent local air-conditioning contractor who serves your part of Hillsborough or Pinellas. Ask what the visit includes before it starts.

What a real tune-up includes

• Condensate drain line flushed and the float switch tested: the single most common August failure in closet and garage air handlers.
• Evaporator and condenser coils inspected and cleaned; a condenser under oaks in Carrollwood or in salt air on the beaches needs it more than once a year.
• Refrigerant pressures and temperatures measured, and compared, not just "topped off". A system that needs refrigerant every spring has a leak.
• Capacitor and contactor tested under load; blower motor and condenser fan amperage checked.
• Thermostat calibration, filter, and airflow; static pressure if the system has never been measured.
• On a heat pump, the defrost control and the strip heat tested before winter.

What maintenance is not

It is not a way to sell a replacement. If the contractor finds a system at the end of its life, you should hear that with the evidence (compressor amperage, coil condition, age, refrigerant) and get a written quote you can sit on until the fall. A maintenance visit that ends with "you need a new system today" on a running unit deserves a second opinion.

It is also not duct cleaning. Dirty ducts are usually leaking ducts pulling attic air in; the fix is sealing (see the ductwork page), and a duct-cleaning pitch that comes with a tune-up should get the same second look.

When

Spring, before June, for cooling; a fall check for heat pumps and strip heat. Maintenance plans from local contractors typically cover two visits a year; ask what each visit includes and whether parts are discounted, and read the terms. Manufacturer warranties sometimes require documented annual maintenance, so keep the invoices.
