Mini-Split Installation

Ductless Mini-Split Systems — Flexible, Efficient Comfort

Garages

Heat and cool your garage for year-round use as a workspace, gym or storage area — without running new ductwork.

Home Additions

New additions often can't connect to the existing HVAC system. A mini-split provides efficient, zoned comfort for the new space.

Basements

Mini-splits are ideal for finished basements that need independent temperature control separate from the rest of the home.

Offices & Commercial Spaces

Control the temperature in individual rooms or zones without affecting the rest of the building — ideal for server rooms, private offices or retail spaces.

Sunrooms & Bonus Rooms

Spaces that get hot in summer and cold in winter are ideal candidates for a dedicated mini-split installation.

High Efficiency

Mini-split systems are often more efficient than extending existing ductwork, and provide precise zone control for the areas that need it.

Is a Mini-Split Right for You?

When a Mini-Split Makes Sense — and When It Doesn't

✅

Good Fit: Garage or Workshop

No ductwork, no problem. A single-zone mini-split heats and cools a garage or workshop independently from the rest of the home.

✅

Good Fit: Home Addition

New additions rarely connect cleanly to existing HVAC. A mini-split gives the new space independent, efficient comfort control.

✅

Good Fit: Finished Basement

Basements are typically the hardest space to condition with central air. A dedicated mini-split solves this directly.

⚠️

Consider Carefully: Whole-Home Replacement

Replacing central air with multiple mini-splits can work but is usually more expensive than a standard replacement. We give you both options honestly.

✅

Good Fit: Server Room or Office

Precise temperature control for a single room or zone without affecting the rest of the building.

⚠️

Consider Carefully: Historic Homes

Mini-splits require wall penetrations for the line set. This affects exterior walls and requires planning in historic or high-end properties.
