Is It Difficult to Install a Ductless Mini Split?


When homeowners are looking to purchase a new air conditioner, they go into it knowing it’s a huge investment. Therefore, they may be tempted to cut corners and do an installation on their own to save money. However, the thing about big investments is that you really need an experienced professional on your side to make sure it operates as effectively and efficiently as it’s meant to. So, our answer to “Is it difficult to install a ductless mini-split” is going to be, “For you, maybe not… for one of our professionals, definitely not!”

Installing a ductless system on your own could leave you with a system that doesn’t operate as well as it could have otherwise or with broken air handlers later on down the line, which we’ll elaborate on below. Read on as we uncover what you need to know about ductless installation.

Should I Hire a Pro for Installation?

Here’s the thing–it is actually easier for our professionals to install a ductless system in your home than it is a traditional central air conditioner. This is because there is no ductwork to consider, and therefore fewer connections to make, and less concern about saving space. Another component of space-saving is the fact that the air handlers can be wall-mounted, up and out of the way.

This said, it’s imperative that you hire a professional for your ductless system installation. Each outdoor unit has up to 4 indoor air handlers connected to it through a conduit–this conduit contains a power line, refrigerant line, and condensate line to rid the air handler of moisture. The conduits are fed through a hole we drill in your drywall behind it and attached to each air handler.

Special Considerations for Ductless Installation

Let’s dive into why it’s so important to hire a professional for this job. Ductless systems operate on heat pump technology. This means they operate using refrigerant. Refrigerant is a chemical blend that condenses and evaporates in order to chill or heat air and return it to your home.

One of the problems that can occur with shoddy ductless installation is refrigerant leaks. These are bad enough for a standard heat pump, as it will cause a drop in cooling power and compressor damage. It’s potentially even more hazardous for a ductless system since the refrigerant is contained in a line snaking its way behind your drywall. This will cause property damage and can be unhealthy for you and your family too.

Water or refrigerant leaks behind the air handler can also cause the air handler to split from the wall, damaging the wall and potentially breaking that air handler. This is why professional service is so important!

Are Ductless Systems the Right Choice for Every Home?

Ductless systems are ideal for bigger spaces with multiple rooms. Each air handler can be independently controlled so if you’re looking for this sort of zoned-cooling (and heating) a ductless system might be perfect for you! In a smaller home or studio setting, if you have the room outside for a standard heat pump or central air conditioner, you might be better off with this, assuming you also have the room for ductwork.
