Room air conditioners can be an affordable alternative to central-air
conditioner systems. New models are considerably more energy-efficient
than those made only a decade ago. Newer features such as electronic temperature
control are more precise than the older knob controls and can also save
you money down the road.
Room air conditioners come in different sizes, with cooling capacities
ranging from 5,000 BTUs (British thermal units per hour) to as high as
30,000 BTUs. The size you need depends on the room to be cooled. Most
of the current models do a good job at cooling, with the better models
keeping the temperature more even than the rest. Check the unit’s
EER (Energy Efficiency Rating) which is posted on every air conditioner.
Also determine the right size air conditioner for the space you’re
cooling (see chart below).
Installation on room air conditioners will normally require two people.
Some models have an outer cabinet that you anchor in the window, into
which you slide the unit. To maintain your air conditioner, clean the
air filter every few weeks. Certain models have a washable filter that
slides out easily. Some units may also have an indicator that tells you
when it’s time to change the filter.
