Design and Installation

We have partnered with Toshiba Air Conditioning to deliver high quality air conditioning installations. We are a 7 year warranty approved partner with Toshiba so you will benefit from long term peace of mind that your investment will stand the test of time.

Our expertise isn't limited to office and home systems - we are experts at designing systems for specialist applications, such as laboratory close temperature and humidity controls, computer and server rooms and industrial cooling systems.

Preventative Maintenance

Of course, all equipment requires regular maintenance if it's expected to last long. This is an area we excel in. We don't just clean filters..... our air conditioning maintenance is carried out to high industry standards to ensure that the systems operate at high efficiency and give you many years of service.

Ventilation Services

a breath of fresh air

Careful Design

Good ventilation ensures that we have a clean and healthy environment in which to live and work in. That's why we give close attention to the design of ventilation systems, because when it comes to the health of building occupants, it must be done right.

In an enclosed space such as an office, CO2 levels can quickly increase when occupied. Poor air quality can lead to loss in productivity and an increase in sickness.A good ventilation strategy not only provides a constant supply of fresh, clean air, it also conserves energy preventing heat loss from opening windows. Heat recovery ventilation is an effective method for providing fresh air at low energy cost.

How can we help?

We can design and install a ventilation strategy to suit your needs.

If you require service or maintenance of ventilation systems, we can provide cleaning and maintenance of ventilation systems and ductwork.
