A ductless AC system is capable of cooling an entire home. However, before you head down this path, you must answer a few key questions:

Once you answer these questions, you can more confidently decide if a ductless AC system can get the job done.

As a general rule of thumb, a ductless AC system has the power to cool almost any home. Of course, there are exceptions to this and a few details to take into consideration. Here’s what you need to know.

1. It starts with making the right purchase

You don’t want to “overbuy” or “underbuy.” Instead, you want to purchase the right system for your current needs, with some room to expand in the future should it be necessary.

This is why it’s best to consult with an installation professional. A DIY install sounds like a great idea — especially if you’re on a tight budget — but it could end up costing you money in the long run.

2. The number of indoor air handlers is important

You need enough indoor air handlers to cool your living space, and that’s based primarily on the square footage of your home and the number of rooms. The larger your home and the more rooms you’re cooling, the more air handlers you need.

A single outdoor compressor can power your entire ductless AC system, but you still need to select the appropriate number of indoor air handlers. Choose too many and you’re spending more money than you have to. But if you don’t stall enough indoor air handlers, you may struggle to efficiently cool your entire home.

3. There’s a limit

Remember how we said that a ductless AC system can efficiently cool an entire home? While this is true, you can only put so much strain on the system before it bogs down.

Depending on the manufacturer and type of system, you can connect as many as nine indoor air handlers to one outdoor compressor. However, the fewer number of handlers you install, the less electricity you’ll use. Not to mention the fact that it’ll cost you less money to install.

Tip: compare systems from the five biggest names in the industry:

Doing so helps you to better understand limits, specifications, pros, cons, features, and more.


When the hot summer months arrive in Boston, you’ll be glad that you have a ductless AC system to keep you and your family cool.
