Recommended System Size for Two Car Garages

Sizing a mini-split for a two-car garage comes down to insulation and how you use the space. For a standard, unfinished two-car garage in Phoenix, we typically install an 18,000 BTU unit to keep up with the heat. If your garage is well insulated, a 12,000 BTU unit is often enough — and the smaller system saves you money on both equipment and installation.

Insulation makes a big difference in efficiency and cost, especially in Phoenix's extreme heat. Get a REAL quote online to see exactly what your two car garage needs for Arizona's climate. Learn more about mini-split efficiency or explore system upgrades.

Proper Unit Placement

Indoor Unit

We install the indoor unit on the adjacent wall where your electrical box is located. This ensures efficient operation and minimal line runs.

Outdoor Condenser

The condenser is placed on the exterior wall directly below where the indoor unit is mounted. This keeps refrigerant lines short and efficient.

Why this matters: We avoid running long linesets across the ceiling or up walls because the pumps that remove water from the system don't have warranties and can leak if they fail. Short, direct runs mean fewer potential issues.

Licensed Electrical Work Services

If an electrical line needs to be run from one side of your house to the other, we have an electrician (licensing pending) who will come at a separate time to run the line properly.

Important Warning

Beware of HVAC contractors who don't have an electrical license but offer to do electrical work. This is unsafe and against code. Always ensure electrical work is done by a qualified electrician.
