  • 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.
  • Expansion Valve: The expansion valve helps control the cooling. If it breaks, your AC might not cool your home enough, making it too warm.
