Commercial Air Conditioning & Refrigeration Installation, Maintenance & Servicing
in the Northshore and Auckland area

Whatever your specifications, North Shore Refrigeration & Air Conditioning can offer the right commercial HVAC installation to suit your needs


As an experienced HVAC company, we focus on ensuring optimum energy efficiency for economic and environmental reasons. With that in mind, we utilise Mitsubishi commercial heat pumps and TemperZone ducted air conditioning climate innovations to maintain the perfect temperature throughout the year and improve air quality by filtering airborne pollutants. By working with such leading commercial heating and cooling system manufacturers, we can offer you the best, most cutting-edge products available on the market today.

To accommodate your HVAC (heating, ventilation and air conditioning) system specifications, our process includes an in-depth analysis of your space and involves the following steps;

  • Calculate cooling load based on size, occupants, sunlight and heat from equipment such as computer servers or other appliances.
  • Determine the best type of HVAC system for the space, including central air conditioning or duct-free split systems.
  • Map out the optimal air distribution system for moving the cool air around your space.
  • Determine the best control system for your commercial building's HVAC installation, including sensors, thermostats, controls and building automation.
  • Ensure your HVAC heat pump system installation for your commercial property or office meets building regulations outlined in Form 12A.
Once your new system is installed, tested, commissioned and optimised to sustain performance, as an IQP (Independent Qualified Person), we recommend our annual planned preventative maintenance. By regularly servicing your equipment, you'll avoid expensive breakdowns, preserve a healthier environment and keep your system performing its best for longer. However, as fully licensed technicians, we also provide a convenient 24/7 air conditioner repair service out of our North Shore base if the unexpected happens.

Create a Healthy Home or Workspace with Fresh Air Ventilation

Auckland’s humid climate, especially in newer homes, townhouses, and commercial buildings, means effective ventilation is more important than ever.
At Northshore Refrigeration & Air Conditioning, we recommend Mitsubishi Electric Lossnay Fresh Air Ventilation Systems — a smart solution to bring clean, healthy air into your home or business.
How It Works
Lossnay systems bring in fresh, filtered air from outside (not from roof spaces) and expel stale indoor air. This helps reduce dampness, mould, and condensation, improving air quality and comfort whether at home or in the workplace.
Thanks to Heat Recovery Technology, these systems capture heat from outgoing air to pre-warm or pre-cool incoming air. This results in a healthier, drier environment that’s easier and more energy-efficient to heat or cool all year round.
Solutions for Homes and Commercial Spaces
The Mitsubishi Electric Lossnay range offers versatile options for different needs:
  • VL-100 Single Room Lossnay:
    compact units ideal for bedrooms, offices, or areas prone to condensation.
  • Vertical Series and Ceiling-Concealed Systems:
    perfect for homes with limited space.
  • Commercial Lossnay Systems:
    ideal for offices, shops, cafes, and schools, these energy-efficient units can be upgraded with optional CO2 sensors to adjust fresh air based on occupancy.
Combine Lossnay with Your Heating and Cooling
Mitsubishi Electric Lossnay Ventilation systems can be seamlessly integrated with a ducted air conditioning system. This combination helps maintain balanced fresh air flow while efficiently managing your home’s temperature.
Why Choose Mitsubishi Electric Lossnay?
  • Constant flow of fresh, filtered air
  • Helps reduce moisture, mould, and condensation
  • Heat recovery to pre-heat incoming air
  • Options for residential and commercial use
  • Optional Wi-Fi Control
Lossnay Wi-Fi Control
The Lossnay Wi-Fi Control makes the invisible visible. You can upgrade your Mitsubishi Electric Lossnay whole home system with Wi-Fi Control to see exactly how many degrees it is pre warming or pre cooling your home in real time.
