Ductless Installation FAQ

How long does a typical installation take?

A typical ductless installation where the indoor unit is mounted above a second floor stair landing and the outdoor unit is mounted on wall brackets takes approximately 5 hours. Installation times can vary greatly based on difficulty, heights, and number of indoor units to install.
Our technicians usually arrive at 9:00 am to start the workday.

Typical Crew Sizes

Typical work crews consist of one licenced experienced professional and one HVAC apprentice. However, there may be more crews on-site depending on the difficulty of the installation.

Cleanliness of Installation

Before any work is started, clean drop sheets are placed from the front door to the location of the indoor unit to facilitate movement of our crews. After the exterior hole is made, all dust from the bricks and drywall are swept and vacuumed both inside and outside. All of the garbage created during the installation is taken back by the technician to be disposed or recycled in an environmentally friendly manner.


During installation, one 3" hole has to be cored through the wall. This takes approximately 20 minutes and will create moderate noise throughout the home. After this core, noise is kept to a minimum.

Electrical Shut-down

Most of our units require two spaces on the electrical panel. During tie-in, the main power will be shut down to the entire home for about 30 minutes.


Typically settlement is made after the installation is completed on the same day. We accept cheques, cash, VISA, MasterCard and AMEX. Credit card payments are processed through the phone by calling into our office.
We also offer flexible payment plans for all of our equipment.


After installation, the technician will familiarize the homeowner on the remote controllers operation, the units features, settings and required maintenance.
