Why Does My Ac Smell Burnt? Discover the Top Reasons and Solutions
Have you noticed a strange smell from your air conditioning unit that smells like something burning? Then indeed you begin to worry, why does my Ac smell burnt?
As we head towards the summer months, air conditioning is an essential aspect of our daily lives. However, if you find a burnt smell coming from your AC unit, it can be concerning and even dangerous. A burnt smell from your AC should not be taken lightly, and it is crucial to address the issue as soon as possible.
Before we dive into the causes of a burnt smell in your AC, let’s briefly understand how an air conditioner works. An air conditioner works by absorbing warm air from a room and passing it over evaporator coils that contain a refrigerant. The refrigerant absorbs the heat from the air, which cools the air down. The cooled air is then blown back into the room, while the warm air is released outside.
In this article, we will discuss why your AC smells burnt, the potential causes of this odor, and what you can do to fix the problem.
What Causes a Burnt Smell from My AC?
