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 a licensed electrician 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 licensed electrician.
