Introduction

Air conditioners work more efficiently when the evaporator and condenser coils or cooling fins are clean and the fins are straight. Save money and keep your house cooler by cleaning a room air conditioner yourself.

How to Clean Your A/C Unit

Most people assume warm air from their air conditioning unit means it’s low on refrigerant. That’s not always the cause. Many times, window air conditioners and through-the-wall air conditioners can’t blow cold air because the evaporator and condenser coils or cooling fins are clogged.

Professional cleaning can be expensive But you can do the entire job yourself in about an hour with a few dollars in supplies. If cleaning doesn’t do the trick, you can always call in a pro (or buy a newer, more efficient unit). But before you do that, check out our step-by-step air conditioner cleaning instructions below.
