Ductless Mini Split Services in Baltimore, MD

The Mighty Ductless provides ductless mini split services across Baltimore, MD – single-zone and multi-zone installation, commercial systems, and repair and maintenance, all handled by Maryland-licensed, EPA 608–certified technicians. Whether you need a new system in a Canton rowhome, a multi-zone upgrade in Towson, or emergency repair in Catonsville, we deliver transparent pricing and same-day scheduling across Baltimore City and the surrounding counties.

Single-Zone Mini Split Installation

A single-zone ductless mini split pairs one outdoor condenser with one indoor head. It’s the right fit when you’re conditioning a single room your central system never quite reaches: a converted attic, a finished basement, a sunroom, a home office built off the back of a rowhome. Most single-zone jobs run $3,000 to $5,500 depending on unit size (usually 9,000 to 18,000 BTU) and how far the lineset has to travel. Not sure what you need? Our mini split sizing calculator gives you the right BTU for your room in seconds. We pull the permit, mount the unit, run the electrical, and start the system in one visit, and we clean up before we leave.

Multi-Zone Mini Split Installation

When you want to condition several rooms, or an entire rowhome, from one outdoor unit, that’s a multi-zone setup. A single condenser feeds two to five indoor heads, each with its own thermostat, so the upstairs bedroom and the downstairs living room aren’t fighting over one setting. These projects typically land between $7,000 and $12,000 based on zone count and layout. Older Baltimore homes with plaster walls and no existing ductwork are exactly where multi-zone earns its keep, since there’s no way to retrofit ducts without tearing the place apart.

Commercial Ductless Systems

Storefronts, offices, server rooms, and additions have heating and cooling needs a residential setup wasn’t built for. We design and install commercial ductless systems sized to the space and the load, handled by the same licensed, certified crew that does our home installs. Not sure what your building needs? We’ll come measure and give you a straight answer.

Maintenance & Repair

A mini split that’s cared for runs quietly and efficiently for well over a decade. One that’s ignored loses capacity, drives up your electric bill, and tends to fail on the hottest day of the year. We offer annual maintenance (coil cleaning, refrigerant check, drain-line flush, electrical inspection), and we repair systems too, including ones we didn’t install. If your unit is short-cycling, leaking water, throwing an error code, or just not cooling like it used to, call before it gets worse.

The Brands We Install

We install Mitsubishi, Daikin, and LG, and we’re a Mitsubishi Diamond Contractor, which means factory training and extended warranty options you won’t get from a general handyman. Every system goes in to manufacturer spec by an EPA 608–certified technician, so your warranty stays intact.

Serving Baltimore City and the Surrounding Counties

We’re based in Baltimore and work across the metro: Towson, Columbia, Dundalk, Catonsville, Essex, Parkville, Glen Burnie, and Cockeysville. Wherever you are, the mini split installation process is the same: an honest assessment, transparent pricing, and a system sized for your actual home instead of an upsell. Many Maryland homeowners also qualify for EmPOWER Maryland and BGE rebates that bring the cost down, and we’ll walk you through what’s available.
