What Exactly is a Mini-Split?

A ductless mini-split is an air conditioner that doesn't need ductwork. You have a small unit outside and a quiet air handler mounted high up on your wall inside. They connect through a small hole in the wall. They are perfect for cooling one specific room that your main AC just can't reach.

Breaking Down the Installation Cost

Installing a single-zone ductless system in the Greater Cincinnati area usually runs between $4,000 and $6,000. If you want to cool three different bedrooms, you need a multi-zone system. Those can push the cost up to $9,000 or more. The price comes down to how far the indoor unit is from the outdoor unit, and how hard it is to run the electrical wires.

Where They Make the Most Sense

We see a lot of split-levels in Anderson Township where the top floor bakes all summer. We also see older homes in Mt. Washington with finished attics that get zero airflow. A mini-split fixes those specific hot spots without having to rip apart your ceilings to run new ductwork. They also provide heat in the winter, making a cold sunroom usable year-round.

What to Expect on Install Day

Installing a mini-split is usually a fast job. It only takes our guys about a day. We drill a three-inch hole through your exterior wall, mount the indoor head, and set the outdoor unit on a pad. But before we quote you a mini-split, we check your main system. We stick to our Repairs First policy. We charge an $89 diagnostic fee to check your current setup. Sometimes a hot bedroom is just a stuck damper or a leaky air duct. We fix the simple stuff first.
