AC repair in Jacksonville and the First Coast

Most AC repairs on the First Coast come down to the same short list: a capacitor, a contactor, a drain line, a blower motor, a coil that needs cleaning, a charge that needs a leak found before it needs refrigerant. A system that runs 3,000 hours a year in this humidity wears these parts first, and a contractor who works the First Coast sees each of them every summer.

Call any hour. If the system has stopped altogether, go to the not-cooling page and call; the three safe checks are there.

What a diagnosis should include

Ask what was measured, not only what was replaced.

• Airflow: static pressure across the air handler, the filter, and the coil. A dirty coil or a crushed return duct makes a healthy system look sick.
• Refrigerant: pressures and line temperatures, superheat or subcooling against the manufacturer's chart. "It was a little low" without a leak search is a recharge, not a repair.
• Electrical: capacitor microfarads against the label, contactor points, amp draw on the compressor and both motors, the condition of the disconnect and the whip.
• The drain: the trap, the float switch, the pan, and where the line terminates outside. In an attic air handler the secondary pan and its switch matter as much as the primary.
• The thermostat and its wiring, the defrost board on a heat pump, and the age and model of the equipment, written on the ticket.

The repairs this climate produces

In order of how often they come up between May and September.

• Capacitor and contactor: parts on the truck, done on the visit.
• Condensate drain: cleared, trapped, and the float switch tested; a drain that clogs every summer needs the trap and the slope looked at, not another vacuum.
• Blower or condenser fan motor, often after a summer of running through a dirty filter.
• Evaporator coil cleaning, or replacement on a system whose coil has leaked; on an older R-410A system a coil replacement is the moment to price the whole system.
• A refrigerant leak found and repaired, then the charge weighed in. A slow leak on a 12-year-old system is the classic repair-or-replace decision.
• Control boards and thermostats after a surge. Whole-house surge protection at the panel is an electrician's job; ask the contractor whether the air handler has its own.

When repair stops making sense

A compressor on a system past ten years, a leaking coil on a system that uses R-410A, or a second major repair in the same year: these are the points at which a written replacement quote belongs next to the repair quote. The replacement page covers what that quote should say (SEER2, refrigerant, permit, your utility's rebate) so the two numbers are comparable.

Condensers at the Beaches, on the Intracoastal, and along the river wear faster in salt air; a contractor should say whether corrosion on the coil or the cabinet is what they are seeing.
