Ductless Mini Split & Heat Pump Installation in Columbia, MD
By Eli, owner of The Mighty Ductless - a Maryland-licensed, EPA 608-certified ductless HVAC contractor based in the Baltimore area. Published September 2026.
The Mighty Ductless installs ductless mini split heat pumps in Columbia, Maryland and across Howard County. We handle single-zone and multi-zone systems, from one room that never gets comfortable to whole-home heating and cooling, with licensed, EPA 608-certified work and an itemized, all-in price up front. Every system we install is a heat pump, so the same wall units that cool your rooms in July heat them through Maryland winters. Installation costs $3,000 to $5,500 for a single-zone system and $7,000 to $12,000 for a multi-zone system covering two to four rooms, fully installed, including the Howard County permit. Most single-zone installations are finished in one day. We are a ductless-only specialist and a Mitsubishi Diamond Contractor. We size every system with a room-by-room load calculation, and the in-home estimate is free: call (443) 535-1477.
Ductless cooling and heating for Columbia homes
A ductless mini split pairs one outdoor unit with one or more quiet wall-mounted indoor units, each with its own thermostat. That makes it the practical fix for the rooms a central system handles badly: a bonus room or finished basement, a bedroom over the garage, an addition that was never tied into the ductwork, or an upstairs that runs hotter than the rest of the house. Because a heat pump moves heat instead of creating it, it delivers roughly three times more heating energy than the electricity it consumes, and zoning lets you heat or cool only the rooms you use. Not sure what capacity you need? Our sizing guide walks through it room by room.
Heat pump replacement in Columbia
If your home runs on an aging heat pump, electric baseboard, or window units, compare ductless before you default to another ducted unit. If your ducts are in good shape, we will tell you honestly that a conventional replacement may serve you fine. If they are leaky, in a crawlspace, or missing, ductless usually wins on both comfort and running costs. Higher-efficiency models may qualify for Maryland EmPOWER rebates, which we factor into your estimate. And if your home already has a furnace or boiler, a mini split does not require removing it: many of our customers run the mini split as primary heat and keep the old system as a backup they rarely touch.

What does mini split installation cost in Columbia?
Mini split installation in Columbia costs $3,000 to $5,500 for a single-zone system and $7,000 to $12,000 for a multi-zone system covering two to four rooms, fully installed - the same pricing we offer across the Baltimore area. The figure includes equipment, labor, refrigerant charging, electrical hookup, and the permit. Where your project lands depends on the brand, the BTU capacity, how many indoor units you are running, and how the line set has to be routed in your home. See our mini split cost guide for the full breakdown.
Do I need a permit for a mini split in Columbia?
Yes. Columbia is in Howard County, and installations here run through Howard County's permitting office - a different office than our Baltimore City and Baltimore County jobs, and one we handle regularly. Maryland requires a licensed contractor to pull HVAC permits, and we take care of it as part of every job, so the work is inspected and code-compliant. An unpermitted install can create problems at resale and voids many manufacturer warranties.
Which mini split brands do you install in Columbia?
We install and service Mitsubishi, Daikin, and LG ductless systems, including Mitsubishi hyper-heating models rated to deliver heat at -13°F. During your in-home assessment we recommend the brand and capacity that fit your home and budget rather than pushing a single product line.
