Our story
Grown exponentially in a few short years
Miller Heating and Cooling started in 2020 with a simple idea: quality products and friendly service at reasonable rates, for heating, cooling and electrical installation, sales and servicing in the Fredericton area and beyond.
Our small, mostly family run business has grown exponentially in a few short years, and branched into the electrical world as well. Today we are a licensed New Brunswick electrical contractor too, so one team can handle your heat pump and the wiring behind it.
Brett Miller applies the expertise gained from over 3000 completed projects to every job, big or small.
