10 air conditioner mistakes that waste energy and money

10 air conditioner mistakes that waste energy and money

As the summer heat increases, more and more individuals around the country are bringing home air conditioning systems (ACs) to keep cool. Although these devices are sturdy, one must use them carefully to ensure maximum energy efficiency. Not doing so could be costly for the environment and one’s pockets. Most people make these ten common mistakes while using their ACs, leading to a waste of energy and money with time.

Blocking the air vents
Blocking the unit’s air vents is a big mistake that wastes lots of energy. Placing furniture, curtains, or other objects in front of the vents blocks air circulation, so the room takes longer to cool. As a result of the obstruction, the AC has to work longer, putting a lot of strain on the system. This can also lead to increased wear and tear or internal damage, requiring more upkeep. To avoid this mistake, one should keep the area in front of the air vents clear of any obstacles.

Forgetting to clean the air filter
The AC unit constantly sucks in air from the surroundings. This air then undergoes a chemical reaction that converts it from gas to liquid and back to gas, which helps bring down the temperature. However, the air absorbed into the system carries a lot of dust, dirt, and dander, which the filters catch. So, one must clean the filters frequently. Forgetting to do so can make the AC work harder. It could also push dust into the room or damage the cooling unit internally. Regularly cleaning the filter helps the system work more efficiently and allows cool, clean air to circulate faster throughout the room.

Installing AC units in a sunny spot
Window AC units must be installed in a spot under a shade. Placing them under the sun’s direct heat causes them to work harder, which consumes more energy. For ACs with outdoor units, experts advise installing them in a clear spot where trees, shrubs, or any other structures do not block them. One should also ensure the device is sealed in properly and no gaps are left for the cool air to escape.

Waiting until summer to check on the AC
Most people wait until summer to check on their AC units. While this may sound normal, it is not a good idea. The reason behind this is simple. Not checking the AC beforehand can cause cooling problems at the peak of summer. AC companies tend to be the busiest around this time, making it difficult to have any troubles fixed promptly. So, one must have the AC tuned up around the spring months to ensure it is ready to keep the home cool throughout the summer.

Ignoring preventative maintenance
This ties in rather well with the previous point. In addition to special check-ups and tuning just before summer, one should try to follow a regular maintenance schedule throughout the year. For window ACs, this can be as simple as installing them at the right place and cleaning the air filters regularly. For larger HVAC units, however, this is a bit more tedious. One will have to clean the condenser coils in the exterior box of the HVAC system at least twice a year.

People should schedule a yearly tune-up appointment with an air conditioning technician. It may include recharging the refrigerant, ensuring proper lubrication in the system, and checking and replacing dirty coils, old air filters, and clogged condensate drains. Actively taking care of the HVAC unit can prolong its lifespan and ensure efficient functioning.

Letting the AC run all day
Leaving the unit running all day, even when no one is at home, is a bad habit many people follow. This mistake can increase energy consumption and utility bills.

Not investing in a programmable thermostat
Gone are the days when one had to adjust the thermostat frequently to maintain the room’s temperature. Today, individuals can simply invest in a programmable thermostat. It can manage the home’s temperature throughout the day and help significantly reduce cooling costs. The device can also automatically shut off the AC when not required, helping increase its lifespan.

Forgetting to check the drain
Some ACs use drains to collect moisture and direct it outside the house. These can get clogged over time, leading to problems with the AC and the surrounding walls and flooring. One should clean the drains at least once every two years to avoid clogging.

Setting the temperature too low
Some people do not understand how an AC system works. They believe that turning the temperature all the way down will make the room cool faster. It does not work like that! Air conditioners run at the same power to reach any set temperature. Setting the temperature lower than required only makes the cooling system work longer, which can be detrimental in the long run. Instead of doing this, individuals can consider investing in a programmable thermostat and setting it at the required temperature, not lower.

Shutting doors inside the home
In homes with a centralized cooling system, shutting the doors may be counterproductive. With the doors closed, the cool air does not have the chance to circulate in the house, making the HVAC system work harder. This ultimately leads to increased energy consumption and high electricity bills.

Top 6 foods that may reduce dementia risk

Top 6 foods that may reduce dementia risk

Many individuals mistakenly believe that dementia is a disease, but it’s a term used to describe symptoms related to memory, social abilities, and thinking. These symptoms can be challenging to manage and can impact daily activities. However, healthcare professionals often recommend implementing a healthy meal plan as a way to improve management. If you’re interested in learning about how your food intake can reduce the risk of developing dementia, read on. What is dementia? As previously mentioned, dementia is not a specific disease. Instead, health conditions like Alzheimer’s disease are among its most frequent causes in older adults. Other known causes of dementia include damage to the blood vessels that supply nutrients to the brain, the formation of balloon-like proteins in the brain, and the breakdown of connections and nerve cells in the brain. While memory loss is one of its most recognizable signs, this symptom alone does not mean one has dementia. Most symptoms of this group of health issues can vary depending on the cause. Hence, here are some of the most common signs to look out for. Memory loss Difficulties while communicating Reasoning and problem-solving issues Poor control of movements and coordination Disorientation Confusion What are the foods that can help reduce the risk of dementia? Typically, dementia and Alzheimer’s are known to be caused by a combination of several factors, such as environmental, lifestyle, and genetic. Furthermore, developing issues such as high blood pressure, diabetes, and heart disease can contribute to cognitive decline in patients. Therefore, healthcare professionals suggest the consumption of nutrient-rich foods to reduce dementia risk as one grows older. Some of the foods that can be added to one’s meal plan are: Avocados Avocados are one of the most commonly known superfoods, which can provide the brain with the needed energy without a spike in blood sugar levels.
Avoid these 15 common shower mistakes

Avoid these 15 common shower mistakes

There is nothing a warm shower cannot resolve. Showering after a long day can be a stress reliever and enhance one’s mood instantly. It also has several other health benefits besides cleansing the body, including facilitating cold relief, boosting immunity, and relieving muscle pain. However, not bathing the right way can give rise to skin conditions such as rashes and eczema. Here are some common mistakes one should avoid while bathing and showering: Not moisturizing after a shower Wiping after a bath can reduce the body’s moisture, causing dry skin, which can lead to rashes and itching. Dermatologists recommend applying body lotion and moisturizer immediately after a shower to retain skin texture and prevent dryness. One should look for hypoallergenic moisturizers that do not have any added fragrances. Bathing in scorching hot water Scorching hot water can damage keratin cells in the skin’s outer layer. Consequently, the skin becomes dry and dehydrated. It is important to balance the water temperature before stepping into the shower. Ideally, the temperature of the water should be lukewarm. Using the wrong towel An absorbent towel that does not feel rough is ideal for wiping oneself after a shower. The most effective way to select the right towel is to check its density, measured in grams per square meter (GSM). Towels with GSMs between 400 and 550 are considered ideal for use after bathing. One should avoid towels below a GSM of 400, as these towels can be thin and rough, causing skin dryness. Moreover, towels made of superior-quality Egyptian or Turkish cotton are extremely soft and perfect for the skin. Soaping the arms and legs excessively While it is important to wash and clean one’s arms and legs, these areas typically do not collect much oil and dust. Hence, scrubbing them excessively can dry out these areas and hamper their natural texture.
15 signs of a weak immune system

15 signs of a weak immune system

The immune system is a complex network of organs, cells, and proteins that act as the body’s defense mechanism against diseases and infections. The system —the innate immune system that people are born with and the adaptive immune system, which develops due to exposure to toxins and microbes. Both parts work together to keep infection-causing germs and toxins. So, weak immunity can make the body susceptible to diseases and other health issues. High stress levels The American Psychological Association suggests that chronic stress weakens the immune system. This is because stress lowers the number of white blood cells (i.e., lymphocytes) in the body that fight infections, increasing the risk of infections such as the common cold. Persistent cold Most adults develop two to three colds per year, which usually last from 7 to 10 days. During this period, the immune system forms antibodies to fight the virus. However, if one keeps catching a cold or is dealing with common cold symptoms for a long time, it could be a sign of weak immunity. Slow-healing wounds When one develops a cut or a wound, the body immediately goes into damage control mode to stop any bleeding and regenerate skin. Immune cells in the body guide this process. However, when dealing with a weakened immune system, wounds take longer to heal. This can make one more susceptible to infections as well. Frequent infections Those with a lowered immunity are at a higher risk of contracting infections such as pneumonia, meningitis, bronchitis, and skin infections. They are also more likely to experience autoimmune disorders, organ inflammation, blood disorders such as anemia, and growth and developmental delays. According to the American Academy of Allergy, Asthma, and Immunology, some signs of weak immunity include: – Having more than four ear infections in a year – Developing pneumonia twice within a year – Dealing with chronic sinusitis or more than three episodes of bacterial sinusitis in a year Fatigue If one constantly feels tired despite getting enough sleep, it may be a sign of weak immunity.
