Commercial & Industrial Air Conditioning & Heating Installation

Can't maintain satisfactory heating or air conditioning temperatures in your office, factory, showroom or warehouse? Poor air quality?


Nortan’s large squad of service technicians have assisted many developers with efficient, rapid air conditioning and heating unit installations.

Commercial developments need more than residential aircon and heating systems. Nortan will design specific commercial systems with greater flow through and power, with cost solutions in mind,

Terry at Nortan owns the company. He can negotiate bulk discounts and cost efficient, quality air conditioning and heating options, installed to your time frame.

We will firstly help you to get the full life out of your current heating and air conditioning solution.  However, if your commercial property requires a new heating or cooling solution, we will assist you to determine the best solution for the unique characteristics of your commercial property - always with both running costs and staff / customer experience in mind.

The following heating and air conditioning solutions are examples of some of the units we recommend.  However, the solution ultimately recommended for your installation will be determined by the specific attributes of your commercial property.

Duct Heaters

Suitable for commercial applications in solid sheet metal ductwork where there may be a separate fan driving the air flow i.e. evaporative coolers for spaces that require large amounts of fresh air, such as a smoking room.

Unit Heaters
