Control board replacement, after we rule out the cheap stuff
The unit won't start, ignores the thermostat, or cycles for no reason. It can feel like the whole thing is haunted. Sometimes it needs a control board replacement.
Often it doesn't. A fuse, a relay, or a loose wire can act just like a bad board.
Boards cost more than fuses, so we test first
We check the control circuit before we order anything, because a board can cost several times what a fuse or relay does and the symptoms look almost identical. If it really is the board, we install a compatible one and confirm heating, cooling, and blower operation.
What the visit covers
- Control circuit testing
- Compatible board installation
- Wiring and safety checks
- Full startup test

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.
