The Best of AHAM’s Air Conditioning Advice

Did you hear that noise? It was summer knocking at the door. After a winter that had most of the U.S. dealing with record-breaking cold spells, I am ready to welcome the summer warmth.
And, it’s not too early to think about pulling out the portable or room air conditioner to help cope with the summer heat when temperatures go from warm to hot.

Maximizing your air conditioner’s cooling potential is not just a matter of flipping a switch. Proper use and care matters for your AC just as it does for all of your appliances. How you use and maintain your air conditioner can affect your energy use and determine whether your AC is ready to go when you need it most.

Even something as simple as where you place your portable air conditioner can make a big difference. We have compiled the best of AHAM’s air conditioning tips to help you get the most out of your air conditioner this summer:

Buying an AC

Once you’ve chosen between a portable air conditioner and a room air conditioner, buying an air conditioner comes down to three major factors: size, capacity and features. Measure the room where the AC will be used. The packaging of many AC units will include a chart of appropriate room sizes, but you can also do the calculation yourself. More power is not necessarily better. You may end up using more energy than you need. That also goes for too small of a unit, as it will have to work harder to cool the space and may not be able to reach the desired temperature for the room. Use this calculator from ENERGY STAR® to find out how much power you need.

AC operating tips

Hot weather can make you cranky and lead you to make bad decisions. One of those is immediately turning your air conditioner to the highest level. This is tempting, but inefficient. Pick a comfortable temperature and set your air conditioner there. Save energy by setting it to a higher temperature if you won’t be in the room for a while. Pull your curtains or shades to block out the sun to make it easier for your portable air conditioner to cool off the room, and make sure your room air conditioner is not in direct sunlight. Consider turning the AC down at night when temperatures outside tend to drop.

If you are using a portable air conditioning unit, keep the exhaust hose as straight as possible. Any kinks can reduce the unit’s efficiency.

AC care tips

Your air conditioner’s use and care manual will include instructions for how often you should clean or replace the unit’s filter. The coils and vents of both window and portable units need to be cleaned periodically. A plastic scrub brush can be used to remove dirt from a room air conditioner. For portable air conditioners, the use and care manual may have specific suggestions, but they may include using a mixture of water and vinegar or other mildly acidic solution to clean a portable air conditioner coil. Finally, break out your vacuum brush attachment to pull out any dirt not picked up during the initial cleaning.
