- Condenser: This part is outside. It cools the hot liquid into a gas that lets the heat go outside. If it gets clogged, your AC won’t cool your room well.
- Evaporator: Inside, the evaporator takes heat from the air to cool your space. If it has problems, like too little liquid, it can freeze and not work right.
