What Type Of Heating
Is Right For Me?

There are plenty of options to keep you and your family warmer in winter months. Some options are more versatile than others such as reverse-cycle ducted systems.
It all depends on your preferences and requirements. Here are some questions you should ask in preparation for an installation quote: 

Energy Efficient

Are you after a system that will be more energy efficient & cost effective in the long term?Some air conditioning sydney systems can cost more initially however consumer more energy in the long term.

Rooms Required

How many rooms require heating in your home? This can open up more options that are more cost effective.

Size of Area

What is the size of the area that needs heating?
Getting an AC system sized to your home is important so your system isn't overworked.

Allergies & Asthma

Do you or your family suffer from allergies/asthma or other respiratory illnesses? Choosing the right systems is just as important selecting the right filtration system for your home, filter option that can capture 90% of particles (MERV13).

The team at Alliance have been so incredible! The electrical team helped us to do a pretty major upgrade on the fuse box. Every step felt clear, transparent and honestly just lovely! Quick to respond to the initial request and had the job lined up and completed within the week. Explained all the pricing, work involved and bonus points that literally everyone who entered the house asked if we wanted them to take off their shoes! Couldn't recommend them more highly.

I recently had some new power points installed and 1 power point and the intercom moved, and the service was excellent. Aden did a fantastic job. He was polite, efficient, and took the time to explain exactly what he was doing throughout the process. I am very happy with the results and would definitely use Alliance again!

Thanks BJ, Theo, Moe and Jake. I think it was probably a challenging installation but they were totally professional, friendly and had great communication. Thanks team! Now I'm looking forward to the warmer weather so I can blast cool air into what would otherwise be a very hot room!

We had a tech from Alliance booked yesterday for a service call on our air con system. A really decent, engaged operator who couldn’t do enough for us through his visit. There was even a couple of extra, system housekeeping tasks that he undertook in a really discrete manner which we didn’t discover until after he’d left. This company has done our air con work for some years now, and we can’t fault them. Thanks very much to the Alliance team (and Emre) for the outstanding customer service.

Tommy, Staad, and Charles did an excellent job installing a replacement split system. Charles took time to work out the most efficient cable routing. Tommy led the team in an installation where the outdoor unit needed to be maneuvered over an outdoor cat enclosure (catio). Calls on approach and arrival on time helped us too.

Frequently Asked Questions

The best heating systems in the market is entirely based on your preference and your home’s requirement.

  • What size do you need?
  • How much will it cost to run?
  • What is the initial installation costs?

Our technicians know and understand air conditioning systems from a large variety of brands. We are authorised dealers of many leading air conditioning brands such as Daikin, Actron Air, Fujitsu, Brivis, Mitsubishi and more. This means that our technicians are qualified to assess, plan and install the most suitable air conditioning solution for you in your home or business. Plus, we also receive exclusive deals and competitions directly from each brand on all their air conditioning systems.

Most importantly, we receive regular and specialised training to make sure our installations are picture-perfect and industry leading.

There are several factors to figure out what the best heating system is most suitable for your home.

These includes:

  • Your budget
  • Functionality of the AC
  • Any allergies/respiratory concerns
  • The amount of rooms
  • The size of the rooms

Our air conditioning technician can provide you with a complimentary, obligation-Upfront Quote to identify the best air conditioning for your home or business. This includes a heat load calculation, space inspection, and efficiency study.

IF IT AIN’T BROKE, DON’T FIX IT” – You’ve heard this saying before, correct? This philosophy doesn’t apply to mechanical devices that can actually breakdown, like your air conditioner.

Gas heating maintenance  should be done every year around the same time and not on a ‘need basis’. This is the best way to keep malfunctions and costly repairs at shore. If you neglect your air conditioner system and skip maintenance, much like your regular dental check-ups, there is a higher chance of it breaking down early or needing major gas heating repairs.

Often more than half of your energy bills comes from heating and cooling appliances, so it only makes sense to keep your air conditioning working efficiently as possible. In fact, research found that proper and regular maintenance of your air conditioner improves efficiency and reduces energy bills by up to 35%. Plus, most importantly, you and your family will be breathing in consistently health and fresh air circulated from the system.

Senior HVAC Technician Josh – “An air conditioning service is not just a filter clean. It is a full system health check and maintenance covering the indoor unit, outdoor unit and interconnecting services. We strip, clean and inspect each part of the system then test and record all the data on a health report sheet for future reference. The idea is to get the system running as efficiently and clean as possible to save the customer money on running costs and improve the hygiene in their home.”

In any room, heat comes from many different sources – computers, machineries, lighting and us, the humans that reside in it. Plus, the sun beaming onto the building, open doors and windows, or areas of leakage in the building can all allow heat to travel into the room. The sum of all these heat sources in Kilowatts tells us the heat load. We use the heat load calculation to identify the air conditioning size needed for your home. The AC’s output must be larger than the heat load/heat gain in your home for the AC to work effetively.

We do have an after-care maintenance agreement which comes in three and five years where your air conditioning’s recommended yearly maintenance is sorted.

This annual service will make sure that the effective functioning of your system is maintained.

Plus, when you sign up for the maintenance program you will also be entitled to an extended warranty on the installation.
