Why ductless

Comfort without the ductwork

Mini-splits are one of the most flexible and efficient ways to heat and cool your home.

No ductwork needed

A small line set through the wall connects the indoor and outdoor units.

Room-by-room control

Each room or zone gets its own temperature, so no more fighting over the thermostat.

Heats and cools

Mini-splits are heat pumps, so one system keeps you comfortable all year.

Built for cold winters

Hyper-heat models keep heating well below freezing.

Lower energy bills

No duct losses and variable-speed operation make mini-splits very efficient.

Quiet comfort

Indoor units run quietly, and the outdoor unit sits away from living spaces.

Where they work best

Perfect for the rooms that need it most

Additions & sunrooms

Comfort for new rooms without extending your ductwork.

Basements & attics

Our tech was knowledgeable, prompt, thorough, and generous with his time and skill. We had an AC unit that was flooding into our den, and the issue was solved in less than 2 hours. I'd give 6 stars if I could!

FAQ

Mini-split questions

Have a different question? Call us at (773) 387-9104.

What is a ductless mini-split?

A mini-split is a heat pump with an outdoor unit and one or more indoor units mounted in the rooms you want to heat and cool. They're connected by a small line set, so no ductwork is needed.

Will a mini-split heat my home in a Chicago winter?

Yes. Cold-climate models like Mitsubishi Electric Hyper-Heat keep heating efficiently well below freezing. We'll recommend the right model for your space.

How many indoor units do I need?

It depends on the rooms you want to condition. One outdoor unit can run one room (single-zone) or several rooms (multi-zone). We'll size it during your free estimate.

How much does a mini-split cost?

It depends on the number of zones, the model and the installation. We give you a free estimate with a firm, upfront price, and qualifying projects can be financed at 0% APR for up to 24 months.

Do you repair mini-splits?

Yes. We repair all major brands of ductless systems, including error codes, refrigerant leaks, drain problems and units that won't heat or cool. You'll get an upfront price before any work starts.

Do mini-splits need maintenance?

Yes. The indoor units' filters, coils and blower wheels need regular cleaning to keep the air fresh and the system efficient. We can clean and service your units for you.
