Mistakes with air conditioning increase your energy bills by 50%: how to avoid them
In extreme climates, air conditioning is very valuable; But there are common mistakes that increase energy bills and affect your finances.
Summer is just beginning and many families are already seeing their electricity bills skyrocket (or will be about to). In some cases, energy bills are reaching levels not seen in years, even approaching $800. What many do not know is that part of that extra expense can be related to common errors in the use or maintenance of air conditioning.
Although it is normal for consumption to increase during the hottest months, experts point out that certain oversights can cause the system to work harder than necessary and considerably increase the monthly cost. The Consumer Reports organization identified three common problems that affect equipment efficiency and that, fortunately, have a solution.
Choosing an air conditioner of the wrong size
One of the most common mistakes occurs when purchasing equipment. Many people think that a more powerful air conditioner will always be better, but that is not necessarily true.
If the unit is too small for the space it is meant to cool, it will constantly work to try to reach the desired temperature. On the other hand, if it is too large, it will quickly cool the room, but may not remove enough humidity from the environment, leaving it feeling uncomfortable.
Before purchasing equipment, it is advisable to correctly measure the space and review the manufacturer's recommendations. Factors such as the number of windows, sun exposure and the number of people who usually occupy the room also play a role.
Poor sealing in the home allows cold air to escape
Another common problem occurs in the installation of windows and doors that, when they are not well sealed, cold air escapes and hot air enters from the outside. As a consequence, the device must work for longer to maintain the temperature.
“Most new window air conditioners come with insulating panels to go over the adjustable plastic side panels,” explained Chris Regan, a member of Consumer Reports' testing team. "But to maximize efficiency, it will still be necessary to use weatherstripping around the perimeter of the unit. And always use the manufacturer's installation and safety hardware."
If the equipment generates strange vibrations or unusual movements, it could also be a sign of a poor installation that needs checking.
Not changing filters on time
Maintenance is probably the aspect most ignored by users and one that causes the most financial havoc. Over time, filters accumulate dust, dirt, and pet hair, reducing airflow and forcing the system to consume more energy. When this happens, the air conditioner loses its ability to cool properly and stays on for longer.
Manufacturers recommend periodically checking the filters and replacing them when necessary. In homes with pets or where the system runs many hours a day, changes may be required more frequently.
Small habits that help save
In addition to maintenance, there are simple measures that can reduce electricity consumption. Keeping the blinds closed during the hottest hours, preventing furniture from blocking the air vents, and correctly programming the thermostat help improve the efficiency of the system.
The US Department of Energy also recommends using appropriate temperatures during the summer to balance comfort and energy savings.
Before assuming that a high bill is exclusively a consequence of the heat, it is worth reviewing these aspects. In many cases, correcting them can make a significant difference to your wallet all season long.
