Spaces Where a Ductless Mini Split Makes the Most Sense

Finished Basements

Comfortable year-round without extending existing ducts.

Home Additions

Heating and cooling for a new room without overloading your current system.

Garages and Workshops

Temperature control in a space you actually want to use.

Sunrooms and Bonus Rooms

Relief for rooms that run hot in summer and cold in winter.

Homes Without Ductwork

A practical option for older homes with radiators or baseboard heat.

Problem Rooms

A dedicated unit for the one room that never feels right.

Converting Your Home to Ductless Mini Splits

Older homes, additions, garages, and finished basements often benefit most from a ductless conversion. If your current equipment is aging or no longer meets your needs, we can remove the outdated system and install a mini split setup designed to fit your home without invasive construction. The result is clean, consistent heating and cooling right where you need it.

Mini Split or Central System? How to Choose

Not every home needs ductless equipment throughout. A quick comparison can help:


  • Choose a mini split for a single room, an addition, or a home with no usable ducts.
  • Choose a central system when you have good ductwork and want whole-home comfort from one unit.
  • Consider both when a central system serves most of the house and one problem area needs extra help.


We will explain the tradeoffs for your home so the decision is clear.

Mini Split FAQs

  • Do mini splits need ductwork?

    No. Each indoor unit connects to the outdoor unit through a small line set, so no ducts are needed. That is what makes them a good fit for additions and older homes.

  • Can one mini-split cool my whole house?

    Usually not. A single indoor unit is best for a room or an open area, so whole-home coverage often takes several units. We can map out what your home needs.

  • Will a mini split work in a finished basement?

    Yes, basements are among the most common places for them. A dedicated unit can keep the space comfortable without relying on your main system.

  • Can I control each room separately?

    In most multi-unit setups, yes. Each indoor unit can be set to its own temperature, so you can adjust comfort for each room.

  • How do I maintain a mini split?

    Clean the indoor unit's filters regularly and keep the outdoor unit clear of debris. A yearly professional tune-up helps the system stay efficient and reliable.
