Can Mice Get In Through The Air Conditioner?  

Mice can get in through an air conditioner. Most probably, it is a regular problem nowadays. Many people complain that mice get into their homes through the air conditioner and they are very irritated already. 

Mice find the air conditioner and pipe entries comfortable to get in the house. They don’t care about what kind of AC this is. It is easy for them to get in, and make their nest there.    

Can Mice Climb Through Air Vents? 

Mice can climb through air vents. Air vents have very few gaps, and we think it is difficult for mice to climb through them. But we don’t know that mice are more flexible than we think, and they are small in size. That helps them to get in quickly. 

Mice need a hole that can lead them to the house. For that, air vents help them, and as we know, mice can climb so fast.   

Why Do Mice Make Nest In Air Conditioners? 

Mice get in through the air conditioner in search of food and shelter. They roam in the whole house for food. If they can not find any haven, they choose an air conditioner to live in. They like the HVAC system because it is warm. During winter, it can be their favourite place to live. It is also a secure place for them. 

Outside, mice live at 26 to 32° Celsius. That’s why, experts say, mice like to stay at 21 to 27° Celcius. Mice find this temperature inside the air conditioner and the house. So, they make their nest in the air conditioner and look around for food. 

Keeping the AC condenser with a shade and the clean area attracts mice more. They can easily make a nest there. 

Another reason is, when mice don’t get any food, they eat the wires of the air conditioner. Most often, homeowners hear a noise of cutting from the AC. When they inspected the AC, they found a mice nest and mice chewed the wires.
