Each zone gets its own head and thermostat, so you condition only the spaces you use. For older downtown homes, that means comfort without tearing into plaster walls and original ceilings.
Where mini-splits shine
- Additions and bonus rooms the main system can't reach
- Historic cottages where new ducts would harm the structure
- Garages, workshops, and she-sheds
- Sunrooms and enclosed porches
- A single hot or cold room that never balances
- Whole-home comfort in homes without existing ducts

What's included with ductless mini-split in Covington
Every ductless mini-split job is scoped and documented up front — here's what you get when we roll up to your Northshore home or business.
- Load calculation for the specific space, whether it's an addition, a hot garage, or a historic cottage room
- Right-sized single or multi-zone system so you condition just the rooms that need it
- Planned line-set routing that keeps runs short and hidden instead of draped across a wall
- Condensate drain routed for gravity or a pump so it clears reliably in our humid, high-water-table conditions
- Wall, ceiling, or floor head placement chosen for even throw and for preserving finishes
- Zoning setup so each head holds its own temperature and you're not overcooling empty rooms
- Startup verification of charge, drainage, and each zone's performance
Perfect for Covington's historic homes
Downtown Covington, Old Covington, and the Ozone neighborhood are full of 19th-century cottages with plaster walls, original millwork, and no practical route for modern ductwork. Mini-splits let us add efficient, quiet comfort while preserving what makes those homes special.
We plan line-set routing, condensate drainage, and electrical carefully so the installation is clean and unobtrusive — critical in historic districts where appearance matters.
Sizing, zoning, and drainage
A mini-split done right starts with a load calculation per zone, thoughtful placement of each head, and a proper condensate drainage plan — in our humidity, the units pull real moisture and that water needs somewhere to go. We'll advise how many zones you need and where line sets and drains should run.
Published mini-split installation benchmarks run about $1,900–$4,800 depending on the number of zones and complexity.
Our ductless mini-split process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Size the space
We run a load calc on the addition, garage, or cottage room so the head matches the real cooling and heating need.
- 2
Plan the routing
We map line-set and drain paths before we drill, keeping runs short, hidden, and easy to service.
- 3
Place the heads
We choose head locations for even airflow and, in historic rooms, for the least impact on original walls and trim.
- 4
Install and connect
We mount the indoor units, set the condenser, run the line set, and route condensate to drain reliably.
- 5
Commission each zone
We verify charge, test drainage, and confirm every zone holds its setpoint before we hand it over.

Ductless Mini-Split FAQs
Published installation benchmarks run about $1,900–$4,800, depending on the number of zones, line-set routing, and electrical and drainage work. A single-zone system for one room sits at the lower end; a multi-zone whole-home system costs more. We provide a written, line-item estimate after assessing your space.
