Parts of a Window Type Aircon and Their Uses
Plain-language guide to window-type aircon parts — compressor, evaporator, condenser, filter, thermostat, and drain — for Philippine homeowners.
Why window parts matter
Window chassis pack the whole refrigeration loop in one box. Knowing the parts helps you describe problems to a tech and avoid cleaning the wrong side.
Core parts
- Evaporator coil (indoor face) — absorbs heat from room air; keep filters clean so dust doesn’t choke it.
- Condenser coil (outdoor face) — dumps heat outside; blocked condenser is a classic “blows weak” complaint.
- Compressor — pumps refrigerant; unusual grinding or failure usually needs pro diagnosis.
- Fan / blower — moves room air across the evaporator.
- Capillary / expansion device — meters refrigerant (not user-serviceable).
- Thermostat / controls — tells the unit when to run.
- Filters — first defense against Philippine dust.
- Drain path — carries condensate; clogged drains leave wet window sills.
What owners should touch
Filters and exterior dust-off only. Leave sealed refrigerant and electrical compartments alone. See window-type hub for install fit.
