Relay replacement after we test the circuit
The thermostat calls for cool and nothing happens. Or the unit starts sometimes and not others. Relay replacement is often the fix.
A relay passes power to the motors and the compressor. When it sticks or burns out, the equipment stops listening.
Sometimes it's the board, not the relay
Relays can sit on the control board itself, so we test the circuit to find out whether the relay failed on its own or the board around it did. Then we replace the right part and run the system.
What the visit covers

AC drain line fix, Port St. Lucie
The drain line had backed up because there was no trap. We cleaned the line to ensure proper flow and installed a trap to prevent future backups. Now the unit can drain safely and efficiently.

Leaking unit repair, Port St. Lucie
The unit was leaking water. A damaged drain line was the issue. We replaced the faulty section and tested the system to ensure everything was sealed properly. A leak can lead to bigger problems if not addressed.

AC drain line cleaning, Port St. Lucie
The unit kept shutting off. Clogged condensate drain. We flushed the line, treated it for algae, and watched it drain clean before we left, so the water ends up outside and not on the ceiling.

York system at a local business, Port St. Lucie
A commercial York system and a wall-mounted mini split at the same business. We serviced the outdoor condensers and the cooling equipment so the place stays cold through August.
