Mini-Split Installation in Tucson, AZ

Ductless heating and cooling for the rooms your central A/C doesn’t reach — garages, casitas, additions, workshops and offices.

Ductless

Cool the room you actually use.

A Tucson garage can top 120° in July, and a back bedroom or casita at the end of a long duct run is often the hottest room in the house. A mini-split solves it without new ductwork: an outdoor unit, a small line set through the wall, and a quiet indoor head that cools and heats.

We install, repair and service mini-split systems for homes and businesses, and place the indoor head and line set so it works well and looks clean.

Great for

  • Garages and workshops
  • Casitas and guest houses

Questions

Mini-Split FAQ

Can a mini-split cool a garage in Tucson?

Yes, when it’s sized for the space and the garage is reasonably sealed. Insulating the garage door makes a big difference.

Do mini-splits heat too?

Yes — they are heat pumps, so the same unit cools in summer and heats in winter.

Do you repair mini-splits you didn’t install?

Yes — we service and repair most mini-split brands.

Do you install mini-splits for businesses?

Yes — offices, server rooms and small commercial spaces.
