It is a myth that HVAC units cause a cold

Some people suffer from a summer cold, especially when using a cooling system.

This has led them to know that a cooling system is the cause of this cold, but in reality, HVAC systems only cool the house.

The frigid produced by these HVAC systems, on their own, can’t cause a cold in humans. The cool and dry indoor air created by a cooling system predisposes you to upper respiratory diseases. It causes dryness in your mucus cavity, irritates the skin, and aggravates your eye membrane, but all these make it easy for you to contract a cold. However, there must be a cold causing organisms in the air for you to catch a cold. Air conditioners also increase the body stress factor. These stress factors come about when your body moves from one air conditioning mode to another, from heat to cold and heat. This constant body temperature change alters your body’s immunity, leaving you vulnerable to disease attacks. In some cases, your body might be suffering from an allergic reaction that mimics cold. It is regular for allergy sufferers to exhibit frigid symptoms that can particularly be mistaken for cold. It is regular to find allergy-inducing contaminants like pollen, dander, dust, and dirt in your heating and air conditioning system’s filters that get blown into your indoor space and may cause allergic reactions. To avoid catching a cold when air conditioning your home in summer, you have to clean your heating and air conditioning unit thoroughly and replace its air filters, but you also have to open your home windows to let in the fresh air and expel stale air from your home. Install an air cleaner to clean your home’s indoor air.
