Ductless Mini-Splits in Concord & the East Bay

Zoned comfort for additions, garages and rooms your main system misses.

Got a room that's always too hot or too cold? A garage you'd like to use year-round, an addition, or an ADU with no ductwork? A ductless mini-split is often the easiest answer. It heats and cools a space without running new ducts, and each zone gets its own control.

All Air Heating and Cooling installs and repairs mini-split systems across Concord and the East Bay. Owner Larry Chambers will look at the space, help you decide where the indoor and outdoor units should go, and explain the price before any work starts. Then we install it neatly and leave the area clean.

Frequently Asked Questions

Do I need ductwork for a mini-split?

No. That's the big advantage. A small line set connects the indoor and outdoor units through the wall.

Can one system cool more than one room?

Yes. Multi-zone systems can run several indoor units off one outdoor unit, each with its own control.

What affects the cost of a mini-split?

The number of zones, the size of the space, how far the units are from each other and any electrical work needed. You'll know the price upfront.

Should I repair or replace my mini-split?

We'll look at its age and the cost of the repair and give you an honest recommendation.
