Your AC usually gives you warnings before it stops working.
A good tune-up isn’t just “cleaning the unit.”
Before we improve anything, we first need to understand how the whole system is performing.
We start with airflow:
✔️ Filters
✔️ Indoor blower
✔️ Supply air
✔️ Ductwork
Because your system needs to breathe.
Then we check the electrical side:
✔️ Capacitors
✔️ Contactors
✔️ Low voltage & high voltage
✔️ Electrical connections
Weak parts usually show signs before they fail.
Then we verify the cooling operation:
✔️ Temperature difference
✔️ Indoor & outdoor coils
✔️ Compressor performance
✔️ Refrigerant cycle
A tune-up is about understanding the system as a whole and catching small problems before they become expensive repairs.
