Need To Know's About Installing Commercial Air Conditioners

We'll visit, assess and plan the most suitable and most cost effective solution for your commercial site and give installation and equipment recommendations. This service is 100% free.
The most regular issue we find from previous installer work is that the units are incorrectly sized for the required space and therefore are not cooling effectively or efficiently. Planning your commercial air-con install is important.
Coalfields are one of the few qualified air conditioning and refrigeration engineers located in the Hunter Valley.
If you experience a breakdown and require an immediate fix, we can promptly install a temporary solution, allowing you the freedom and space to make the right decision for replacement equipment.
The solutions we can provide are from a simple split-system unit, right through to industrial package air conditioners. We assess your site first and make recommendations.
To reduce energy consumption, we often install automated variable air volume systems (VAV) to monitor and adjust air quantity to perfectly suit the conditioned space.
