How often do I need air conditioning and heating maintenance?

At GlobalRez Air Conditioning, 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.

Why should I service my air conditioner?

Regular servicing and maintenance keep your unit running at maximum efficiency, significantly extends the lifetime of a unit and reduces operating costs. In addition, routine maintenance will ensure that the unit qualifies for the full warranty of up to ten years rather than just the standard manufacturer’s one year warranty.

What kind of maintenance do you provide?

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.

Why do air conditioners have a hose?

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

The internal compressor gets very hot in the process and this excess heat must be exhausted away. 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.

Who have you installed air conditioning for?

We have installed air conditioners for most of the biggest and best-known companies in the Australia. Check out our Brands We Carry  to see just some of the companies we’ve worked with. When you choose the Air Conditioning Company, you are assured the highest quality at the keenest of prices.

Can I Use a Portable Air Conditioner in a Room Without a Window or External Door?

Most home/office portable air conditioners require a 5-inch (12cm) in 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 (e.g. 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.

What is Duct Cleaning?

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

What are the advantages of equipment with variable speed fans?

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’re comfort needs will be met.

What is a solar hot water system?

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.

Great company to deal with. Gary has his good stuff together, quote over the phone looking at my property on Google maps. (Agreed with his assumptions about the ease of install), happy with the price. Tom did a site inspection at my convenience, really nice knowledgeable bloke. Team of installers lead by Matt turned up on time. Four really nice blokes, did a great job (full removal of the old system), very happy with the end result. You will not be disappointed dealing with Globalrez. Phil.

Just had our Mitsubishi Heavy Industries ducted air conditioning system installed at the beginning of the week. It was a pleasure to deal with Globalrez. From the initial contact with Gary, who provided all of the information we needed to make an informed decision. They were also the only company we contacted that introduced us to AirTouch 4 system, which allowed us to have a temperature sensor in each of our 5 zones and be able to independently set the temperatures. This system also allow us to nominate any zone as the spill zone and be able to change that at anytime. There was no need for a constant zone, which was exactly what we wanted. The installation team were brilliant. Matt came out initially to do the final check and I liked his can do attitude, and nothing was a trouble for him. On the day of installation, they had the whole team on site and were able to complete the work within the day. Even my neighbours were very surprised on them being able to complete a large job like ours within a day. We’re really happy with the finished product and installation A very professional company to deal with.

Couldn’t be happier with the service of GlobalRez and Justin who installed our air conditioners. Justin was incredibly efficient and personable. His work was very professional and he left our place spotless after he’d finished. Chris and Gary from the GlobalRez office were also very quick to arrange quotes and responded to all emails on the same day.

If I could give these guys more than 5 stars I would. They were outstanding. Two days after an enquiry phone call, Tom and Matt were on site to check what we needed. Then Gary at the office quoted the job quickly and the price was competitive. The install was quick and easy with all the staff on site being courteous and friendly. They cleaned up all the mess of a big job with no fuss and removed all unwanted materials. I have done dozens of renovations and many air con installations in my time and I can say with 100% surety these guys are simply the best I have ever encountered for service, price, installation... the works! OUTSTANDING!!!!!!!!!

Justin installed our duel system last week & I could not be happier with his service. He was professional, gave me a clear expectation of the time frame and cleaned up to the point the place looked better after he left than prior to his arrival. If Justin is typical of the quality of people you have working for you than you are on a real winner. From a very satisfied client.

From the initial inquiry via Globalrez website for a quote, to completion of the installation of my ducted air conditioning system, I could not have been happier with the service I received. Everything was carried out in a totally efficient, prompt and polite manner. When Nathan came out to inspect my home for installation, he took the time to go through what would take place and what he considered would be the best unit for optimal outcome in my situation. With installation day, my home was respected and the removal of my old system and the installation of the new one, went according to what I was told, with the whole team being exceptional! Thank you to all concerned for a stress free, pleasant experience. I would recommend your company and service without any hesitation.

I had a Daikin ducted airconditioning installed 2 weeks ago. Dealing with the Globalrez team from the amiable Gary who managed the booking to the entire installation team was a very pleasant experience. Installation was done within 2 weeks of booking, the team arrived on time and worked in precision that the job was completed within 5 hours. They left the place in a tidy condition you wouldn’t notice that work was done. Operating the controller was explained thoroughly, answered any questions and concerns we raised and they did not leave the place without ensuring that all is working. The price was very reasonable and I can truly say Globalrez is good value for money. Thanks to Gary and the entire team.

Justin was early to the job and worked hard single-handed all day without a break to finish the job. Mitsubishi A/C is great - I had no idea there was so much work in the install. Great job and many thanks to the very personable Justin L.

We had our ducted air conditioning replaced by Globalrez and the process was perfect! Gary was a pleasure to deal with in determining what system was required and quoted an very reasonable and competitive price. Everything was transparent and communication was great. Installation by Tom, Nathan and the rest of the team was fantastic. The installation team consisted of about 7 guys, all of whom were hardworking, professional and courteous. Our old system was removed (including all ducting) and a new system was installed - all in one day! The old system and all rubbish was removed and our place was left spotless! We are now enjoying our new air con in the sweltering Aussie heat. Globalrez provides a platinum service and I can’t recommend them enough!

An extremely professional service from the entire team. From the start dealing with Gary, and then Tom for the installation team - everyone was extremely helpful, polite and full of knowledge. Globalrez installed both a ducted system and split system, and found an outstanding solution for the return air grill. Rubbish was always collected, and worked around hours that suited me. Couldn't recommend the team highly enough (Justin, Nathan, Chris, Riley + others (sorry forgot your names))
