Circumstances Where You Don’t Need A Permit To Install A Mini-Split

There are a few situations where you won’t need a permit to install a mini-split air conditioner.

The power unit of mini-split air conditioners are measured in units called BTUs. The necessary number of BTUs depends on several factors. These factors are the room size, cooling needs, and how hard the AC works to keep up with weather conditions.

You shouldn’t need a permit if your mini-split ac unit runs off less than 36,000 BTUs per hour. But what if you require a unit that uses more energy than this? Then, you will need to obtain a permit before working on the project.

You do not need a permit for HVAC systems that operate from a window. These generally are not strong enough to cool large spaces like a mini-spit. This is one reason why you need proper permitting before installing a mini-split.

There is an exception where you will need a permit for window units. You will need a permit if the window unit requires affixed brackets to the exterior of the building. Additionally, you’ll also need a permit if there needs to be alterations to the window frame or sash.
