With prolonged hot temperatures, we often use air conditioning (AC) to provide comfort, but then shocked to see a bill of electricity soaring. According to experts, there are some mistakes we have done unconsciously that degrade usability, usability, and even sacrifice safety.
Quoted from Time on Thursday (21/7/2016), Mark Mendell, a scientist at the Indoor Environment Group, Lawrence Berkeley National Laboratory, said, “If we have a system that care is perfunctory, the system can be contaminated with microorganisms that can be dangerous if inhaled.”
According to Mendell, asthma and allergic problems include the impact that may arise as a result.
Here are eight common mistakes people make related to AC at home and suggestions for adjustments to help our lungs and wallets:
- Not Replacing or Cleaning the AC Filter
At the very least we have to replace the filter in the central AC unit once in three months, or it can be up to once a month if the cooling system is installed continuously. If you neglect to do this, dirty filters may interfere with airflow or even freeze the evaporator coils, says James Braun, professor of engineering and a director of the Center for High Performance Buildings at Purdue University. Filthy filters can increase cooling power bills by 5 to 15 percent while shortening overall system life. Fortunately, replacement filters are not too expensive. If it has a split AC, there is usually a panel that can be opened in order to wipe the filter using a cloth without changing the filter.
- Not Performing Annual Services
According to James Braun, there are some video clues to clean our coils and AC strings. Cleaning is important to keep the operation in order to keep the system smooth and efficient. Or it could be calling a handyman to clean the air conditioner once a year. In the US, the Department of Energy provides tips on finding an air purifier expert.
- No Programmed Thermostat
There are some people who always remember having to adjust the thermostat before leaving home. But most people need a programmable thermostat to save on electricity bills.
The programmed thermostat automatically raises the temperature when we’re at work or outdoors, Braun said. He added that now there is a “smart” thermostat that can be programmed using a smart phone. Like what ActronAir Australia does. They have ActronConnect’s Zone Screen that can gives you easy control over which zones are on or off. You can even give each zone the name you prefer: Kate’s Room, TV Room, or whatever you like. And if you have the Ultima upgraded system, the actual temperature of each zone is also shown.
- Installing Temperature Too Low
Research shows that the human body can actually adjust to hot or cold temperatures, usually within one to two weeks. We can trim about 3 percent of the total electricity bill from AC usage for any 1 degree Fahrenheit-increase in temperature equivalent to a temperature increase of 0.56 degrees Celsius. Coupled with the potential environmental benefits due to reduced use of air conditioning. Try to install about 70 degrees Fahrenheit (about 22 degrees Celsius).
- Less Use of Fan
Fans of various types, especially those mounted on the ceiling, can help circulate the cold air throughout the house. This fan help reduces the load on the AC system, Braun said. Make sure the ceiling fan rotates against the clockwise direction of the summer, since such rotations provide better airflow.
- Wrong Placement for Thermostat and Ventilation
If sunlight or lights hit the thermostat almost all day, temperature readings by the thermostat can be missed, forcing the air conditioner to cool the room even though the chamber is cool enough. Especially if we are all day outdoors so we do not realize that the cooling system has been working hard because one put the thermostat, Braun said.
- Cooling the Empty Room
If the air-conditioning channel is open in every room in the house, we instead cool the unused part of the house every day. Try walking around and close the blow channel that opens into unused spaces. Also close the closet doors so that the closet space does not confiscate the cold air.
- Not Utilizing Curtains or Curtains
The bright sun is the main enemy of our air conditioning system. By closing the curtains we are blocking sun exposure and protecting our space from the heat of the sun, experts say.
