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.

Two Trane systems, one bad condenser, Palm City
Two Trane systems in one house, and one had stopped cooling. The fault was at its condenser. We fixed it, checked the refrigerant, and looked over both units. We told the homeowner where each one stands. Nobody tried to sell a second system.

New R-6 ductwork, Palm City
Old ducts out, new R-6 duct in. We sealed every joint, strapped the runs so they don't sag, and reconnected the attic ducts so every room gets its air.
What happens when you call
Tell us what the system does when the thermostat calls. JD usually picks up. If he's under a house or on a roof, someone calls you back. Ask about the diagnostic fee and we'll tell you before anyone drives out.
