Air conditioner parts replacement in Port St. Lucie

AC parts replacement: one part, not a new system

One part fails and the whole unit stops. It's frustrating, and it's usually fixable. AC parts replacement is most of what we do.

Motors, capacitors, contactors, relays, and boards. We find the one that failed and replace it.

Compatible parts, then a full test

We match the part to the equipment, check the wiring around it, and run the system before we leave. If something else is close to failing, we'll tell you and let you decide.

What the visit covers

  • Diagnosis of the failed part
  • Motor, electrical, and airflow parts
  • Wiring and connection check
  • Performance testing after the repair

Float switch replacement, Port St. Lucie

The drain clogged and the float switch at the evaporator coil did its job and shut the system down. We cleared the drain, replaced the switch, and got it cooling again without water where it shouldn't be.

What Port St. Lucie homeowners ask us

That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.
No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.
Yes. We answer 24/7. Sundays and holidays are billed at double time.
