Warm weather most of the year is the norm for Florida—except
on those days when it’s roasting hot! We rarely get a break from the heat during
fall, and one of the major problems for air conditioning systems at this time
of year is that they’ve already accumulated immense amounts of wear through
summer. The spring tune-up and inspection you scheduled for you AC seems like half
a lifetime ago.
That preventive maintenance visit in spring is the best way to help your air conditioning system make it through the fall heat. But you can make the AC’s job much easier if you recognize its limits and don’t push it over them. You’ll reduce the chance you’ll need AC repair in Lake Worth, FL.
The 20°F Air Conditioning Limit
All central air conditioning systems that are accurately
sized for the space they are cooling can lower the indoor temperature by 20°F. For
example, on an intense 90°F day, your home’s air conditioner can lower the
indoor temperature to as low as 70°F. This doesn’t take into account other
factors in the house that can allow in extra heat (such as sun exposure on
windows) or keep heat out (effective insulation). But it does give you a good
concept of what the AC is capable of and how to best set the thermostat.
So if the temperature outside is around 95°F, we don’t recommend
you set the thermostat lower than 75°F. In general, the higher the setting, the
better it is for the AC as well as your bills. The smallest difference between
the indoor and outdoor temperatures means slower heat gain in your house. Pick
a higher temperature that you still find comfortable and make it the regular
target. We recommend aiming for 78°F.
Putting the thermostat lower than the AC’s cooling capacity
won’t give you a cooler house—it will only force the air conditioner to run
continually as it tries to reach an impossible setting. This wastes power and can
overstrain the air conditioner to the point it needs to be repaired.
Why ACs Have This Limitation
You might wonder why a home’s central air conditioning
system would be limited to a 20°F capacity. Why not make the AC more powerful for
the extremely hot days?
The reasons manufacturers design residential air conditioners
this way is for energy efficiency and comfort. To lower the temperature more
than 20°F would require sending out air that’s extremely cold—almost the
cold of a refrigerator’s freezer. This drains so much energy that it would
rarely be worth it. Worse, the intense cold would create uneven cooling: anyone
near the room vents would be so cold they’d need to wear a coat on a hot day.
The 20°F capacity results in the best cooling situation for homes when it comes
to comfort and energy use.
