Tracking Down the Cause of the Power Loss
Once on site in Summerville, we began with a full diagnostic of the HVAC system.
With no power reaching the unit, several components needed to be checked carefully. As we opened the system, the cause became clear. A lizard had found its way inside the unit and damaged multiple critical parts.
The inspection revealed a defective control board, failed thermistors, a damaged contactor, and a compromised reversing valve coil. Any one of these issues could stop a system from operating. Together, they explained why the unit would not start at all.
Situations like this are not unheard of in the Lowcountry.
Summerville’s warm climate and local wildlife can create unique challenges for outdoor HVAC equipment. Small animals can squeeze into tight spaces, and once inside, they can wreak havoc on wiring and electronics.
Replacing Components and Restoring Operation
After explaining the findings to the homeowner, we replaced the damaged control board, thermistors, contactor, and reversing valve coil. With the new components installed, we moved into the testing phase.
We ran the system in both heating and cooling modes, allowing multiple natural calls from the thermostats to ensure consistent operation. We also confirmed the heat kit engaged properly when needed, which is critical for comfort during cooler spells in Summerville.
Once performance was verified, we reassembled the unit. As part of our process, we neatly reorganized the system wiring. Clean wiring improves reliability, reduces future troubleshooting time, and reflects the level of care we bring to every job.
A Reliable Result for a Familiar Customer
By the time we finished, the HVAC system was running smoothly again. Power was fully restored, heating and cooling responded correctly, and all components worked together as designed. For the homeowner, the relief was immediate.
The feedback said it all.
“Thanks, Guys!!” Short, simple, and appreciated.
