Welcome to Jeff Mouritz GAS&AIR

Choosing an air conditioning system to provide year round comfort is very much a personal decision and a matter of taste. No two people are the same and for that reason, each air conditioning or heating installation varies from the next. Experience tells us that by offering the right information,you can easily choose the right cooling or heating product to satisfy your particular need.

One of the reasons more customers turn to us is because we guarantee air conditioning performance.We have our own fully trained professional installation teams that work for GAS&AIR all year round and everything is supported by our in-house air conditioning service division.

No matter the requirement we offer air conditioning solutions that work.

At Jeff Mouritz GAS&AIR we are continually striving to become Perth’s, indeed Western Australia’s, best air conditioning company. For over 40 years we have specialised in Air Conditioning for all types of Residential and Commercial applications. This might be a small Split System Reverse Cycle unit in townhouses or flats, Ducted Inverter Refrigerated systems in large 2 storey residences right up to industrial sized Evaporative units in schools, office complexes and industrial units.
