Get Every Room Comfortable Without Opening Walls

Many Rhode Island homes have rooms without ductwork, making them difficult to heat or cool. Ductless mini splits provide efficient heating and air conditioning without major renovations. Each indoor unit offers individual temperature control, helping reduce energy waste. Proper sizing and placement ensure year-round comfort in basements, sunrooms, and bedrooms.

Pick the Setup That Fits Your Home

Every home is different. Most of our installs fall into one of these 3.

Single zone

One room

One outdoor unit and one indoor unit. Great for a bedroom, home office, sunroom, or addition.

Multi zone

More rooms or the whole house

One outdoor unit runs two to eight indoor units, and each room gets its own setting.

Keeps heating below 0°F, so it can replace or back up oil, propane, or baseboard heat.

What Goes Into an Install That Lasts

Many mini split problems trace back to sizing, the line set, or the drain. Here is what a good install looks like.

Sized and placed for each room

Each room is sized by how much heat it loses and gains, not square feet alone. Too big and it short cycles and leaves the air damp. Too small and it runs nonstop. Then the indoor unit goes high on a wall where the air can reach the whole room.

Outdoor unit and power done right

A stand or wall bracket keeps the outdoor unit above Rhode Island snow. Each system gets its own breaker and outdoor shutoff switch, and line hide covers protect the lines and keep the outside neat.

A tight, clean line set

The copper lines are pressure tested and put under a deep vacuum to pull out air and moisture before the refrigerant is released.

A drain that won't back up

The drain line slopes down and away, or runs to a small pump, so water never backs up into the room.

Questions About Ductless Mini Split Installation

A single zone mini split for one room usually costs $3,500 to $6,000 installed. A multi zone system usually costs $5,000 to $10,500 or more, about $1,000 for each added zone. Clean Heat RI and Rhode Island Energy rebates can lower the price.
