Living or working near an old and moldy air conditioner can increase your chances of respiratory infection. Mold also causes symptoms like throat irritation, wheezing, and congestion. If you are feeling any of these symptoms, it may be time you checked out your surroundings for mold.
If you work in an air-conditioned building with poor ventilation, it can raise your risk of “sick building syndrome.” Symptoms include headaches, dry cough, dizziness and nausea, trouble concentrating, fatigue, and sensitivity to odors.
TL;DR: Carbon monoxide (CO) leaks from your HVAC system can be dangerous and go unnoticed without proper attention. Signs of CO leakage include flu-like symptoms, yellow or flickering pilot lights, soot buildup, and strange odors.
Leakage from a damaged air conditioner can harm the environment and release toxic fumes that can make you and your family sick.
Dry eyes, lethargy, dehydration, dry or itchy skin, headaches, respiratory issues, allergies and asthma, noise pollution, infectious diseases, and indoor pollutants are among the common health concerns associated with prolonged exposure to air conditioning.
It is advisable to use a humidifier alongside your home conditioner if you experience any air conditioning sickness symptoms. Also, drink a lot of water during the day to reduce this effect.
If any of the dirt, bacteria, dust, and other particulate matter that's hiding in your vents gets into your lungs, it can cause some serious infections and sleep issues. Sleeping with the AC on can also cause some physical issues, including dehydration.
Legionella bacteria can proliferate in air conditioning systems, particularly in cooling towers. Inhalation of contaminated aerosols can lead to Legionnaires' disease, a severe form of pneumonia. Symptoms include high fever, cough, and muscle aches. In extreme cases, it can be fatal.
Chronic freon poisoning consists of long-term exposure and typically affects HVAC technicians. A leaky air conditioner or refrigerator can cause acute freon poisoning. According to WebMD, the symptoms of acute freon poisoning include: Sore throat and swelling in sinuses.
In more severe cases, avoidance may not be enough. Then, treatment may include corticosteroids or other immunosuppressive medication to reduce inflammation and prevent your immune system from reacting to the allergens you inhale.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
Freon: This refrigerant is common in older AC units. While it's essential for cooling, a leak can be harmful if inhaled in large amounts. Carbon Monoxide: Not directly a part of the cooling process, but if your AC is combined with a furnace or has any combustion processes, there's a risk of CO production.
[12] The symptoms usually disappear hours or in some cases days after removal from that environment.
One significant health risk is refrigerant poisoning. Inhaling Freon or other refrigerants, even in small amounts, can lead to headaches, dizziness, and nausea. Exposure to refrigerant fumes can quickly escalate to more severe health issues, such as loss of consciousness and even death.
They can make your family sick:
Your family may suffer upper respiratory infections if they experience coughing, headaches, sneezing, nasal congestion, sore throats, runny noses, and low fevers due to dirty air-conditioning filters.
A dirty AC system can lead to many breathing problems. If you have a runny or stuffy nose that develops when you're inside but goes away when you leave, this is a clear indication that your air conditioner's filter is dirty.
Possible Harmful Chemicals: Other sources suggest that portable AC exhaust could contain harmful chemicals and gases like benzene, toluene, formaldehyde, carbon monoxide, and nitrogen oxides. These substances can cause respiratory issues, headaches, dizziness, and other health problems if present [2] [3].
One of the most overt signs of a Freon leak is a sweetish smell comparable to nail polish remover. This may indicate the general location of the leak and where to begin testing. Oil spots on tubes, joints or near HVAC components may come from the oil in refrigeration coolant which would indicate a leak.
Fatigue or Feeling Sick May Relate to the AC
The cold temperatures may cause fatigue, headaches, dizziness or other symptoms of a cold or flu. A simple solution for this problem is turning up the temperature.
Legionnaires' disease, the pneumonic form, has an incubation period of 2 to 10 days (but up to 16 days has been recorded in some outbreaks). Initially, symptoms are fever, loss of appetite, headache, malaise and lethargy. Some patients may also have muscle pain, diarrhoea and confusion.
If your air conditioner smells musty, take action to solve the odor immediately. Mold inside the HVAC system impacts indoor air quality, and it can spread and grow in other areas of the home as well as cause health issues or increased allergy symptoms due to breathing indoor air heavy with spores.
Drink more water to keep yourself hydrated and your throat and nasal passages moist. If you are experiencing exhaustion, headaches, and sore muscles and joints, turn that air conditioning down! Your air conditioner should be set at a comfortable, room temperature.
Here's what to consider: Climate and Weather: In regions with warmer climates or on cooler summer evenings, a fan might be all you need to stay comfortable. However, an AC is better when dealing with extreme heat or high humidity.
