Globalrez supply and install air conditioning solutions across Sydney, Wollongong, Central Coast and the Sunshine Coast.

Regular servicing and maintenance ensure your air conditioner is running at maximum efficiency as well as significantly extending its lifetime and reducing operating costs. Routine maintenance through Globalrez will also mean that your unit will qualify for the full warranty of up to ten years, rather than just the standard one-year manufacturer’s warranty.

Air conditioners contain a refrigerant gas that needs to be quickly pumped round the system by a compressor (to achieve very low temperatures).

In this process, the internal compressor gets very hot and this excess heat must be released. The usual method of exhausting away the hot air is with a hose that needs to go out a window or a door to the outside.

Most home/office portable air conditioners require a 5-inch (12cm) diameter flexible hose to exhaust the hot air from the room. In most cases, this hot air is also exhausted along with the excess humidity in the room, so this must be vented into the outside atmosphere such as a window or external door.

There are a few exceptions to this rule, some dry exhaust air conditioners can be vented into a suspended (false) ceiling or into a spare room that you don’t mind getting hot. These units have built-in water tanks which allow the units to expel hot, dry air out the hose.

Variable speed fans operate on a simple principle – they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. This helps control humidity levels, utility costs and system noise. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, you’ll remain comfortable.

At GlobalRez, we recommend that you schedule tune-up services twice a year—once before the start of the summer months, and once before winter begins. This can help you avoid unnecessary problems during the hottest and coldest months of the year.

We provide a comprehensive maintenance service. While many air conditioning companies simply hover your filters and leave, we fully service both the indoor and outdoor units, making sure that they are operating within normal parameters and are running at their full capacity.

We have installed air conditioners for some of the biggest and best-known companies in Australia. Check out the brands we carry to see just some of the companies we’ve worked with.

Duct cleaning refers to the cleaning of the various heating and cooling system components of forced air systems. This includes the supply and return air ducts and registers, grills and diffusers, heat exchangers, heating and cooling coils, fan motor and fan housing, and the air handling unit housing.

A typical solar hot water system is made up of solar collectors, a storage tank, a gas or electric booster and a solar controller and pump for split systems.

There are two types of systems available

  1.   Close Coupled systems
  2.   Split systems

Close-Coupled systems have the storage tank above the solar collectors all located together on the roof. Close-Coupled systems rely on thermosyphon to operate: cold water from the bottom of the tank falls to the inlet at the bottom of the solar collectors. The water is heated by the sun, rising up through the solar collector and back into the middle and top of the tank.

Split systems have the storage cylinder located on the ground and the solar collectors located on the roof. Split systems use a solar controller and pump to transfer cold water from the tank to the solar collectors to be heated and returned to the middle or top of the tank. The solar controller compares the temperature of the water in the solar collector to that in the tank. When the collector is hotter than the tank the pump is switched on, transferring the solar heated water to the tank.
