Health Dangers That AC Refrigerant Leaks Can Cause

Heating and air conditioning system is the most essential equipment of any residential or commercial area. It keeps you comfortable during the changing outdoor temperatures. Therefore, a malfunctioning AC can be a nuisance, especially in extreme weather. There can be many reasons for an air conditioner to malfunction. One of the most ignored reasons can be AC refrigerant leaks.  A refrigerant is one of the most imperative but at the same time, most overlooked parts of your air conditioning system. 

What is a Refrigerant? 

An air conditioner requires coolant to cycle both cold and hot air and disperse it properly. This coolant is within the unit’s copper tubes. Afterward, it cycles through to circulate cold air and expel hot air outdoors. This chemical blend is responsible for cycling through the system, changing from a liquid to a gas as it absorbs and releases heat from inside your home. However, over time, issues in your line sets can lead to the loss of refrigerant, which can cause many problems. This can cause your AC to malfunction. 

Aside from a dysfunctional air conditioner, many health problems may arise out of refrigerant leaks. If neglecting a leaking air conditioner,  this coolant can have severe effects on your physical health. This guide will teach you the refrigerant leak symptoms and dangers.
