In most cases our temperatures are only a degree above that of our capital city Brisbane, but that is little comfort when facing the scorching heat of a summer’s day or the discomfort of tossing and turning through a very warm night. How great it would be to simply turn on the air con and escape the heat for a while or to be able to sleep soundly through the night. We’re going to have a look at what’s involved with installing an air conditioning unit and the importance of having a professional air conditioning installation Bundaberg carried out for you.

Is there really a need to have a professional installer 

I guess that if you are a qualified electrician or HVAC installer and have better than 10 years experience at air conditioning installation this question doesn’t even rate. However, taking into account the fact that you could fry yourself or start a fire that would burn your house down if you lack those professional attributes, then it is probably better to at least contact a professional air conditioning installation Bundaberg specialist and get a quote. This ensures that the installation 

  • Does not void any manufacturer’s warranties 
  • Ensures energy efficiency
  • Ensures air conditioning efficiency throughout your house
  • Will not start a fire
  • Is safe for the users (your family)
  • Is aesthetically appealing 
  • Looks and operates like it was professionally installed
  • Complies with Australian standards

Incidentally, an HVAC installer is a heating, ventilation and air conditioning installer. Usually, a tradesman who is well trained and qualified in all aspects of air conditioning installation.

Some of the processes needed:
  • You need to select the most appropriate location for the internal unit if you decide to proceed. 
  • A wall with internal studs to take the weight of the unit
  • A location that has clear space around the unit to allow free flow of air throughout
  • Unobstructed space of at least 15 – 25 cms around the unit itself
  • Access to the external unit through the wall for plumbing and electrical conduits
  • A location at least 1 mtr away from any other electrical componentry
  • A location away from gas lines or contaminants 

You can see from the above points that you need to discern the best location so that you can obtain the maximum benefit from your unit which a professional air conditioning specialist can ascertain initially, prior to starting your job.

So what’s next if we choose to proceed DIY

Install your internal unit using the studs in the wall as anchors for the base plate of the unit, and do the plumbing and electrical connections suitable for your unit. Wiring and plumbing varies significantly from brand to brand so adhere to the manufacturer’s data and instruction sheets rigidly. Additionally, non-adherence to the manufacturer’s instructions can and may void the warranty and damage the unit.

Installation of the external condenser unit 

The external unit needs to be within 15 mtrs of the internal unit to maximise cooling efficiency and located away from heavy trafficked, hot, dusty, contaminated or wet areas, preferably in the shade. Install isolator switches and circuit breakers to both units also and do the hook-up. The external unit needs to be mounted on rubber feet on a solid base with no movement and good airflow around it. 

The unit then has to be charged with appropriate Australian standards refrigerant using the 2 and 3-way valves and a vacuum pump. Here manufacturer’s instructions are vital so that you gain the correct pressures for the brand unit you have selected. This is, of course, the province of an air conditioning installation Bundaberg specialist. Failing to adhere to these instructions may not only void your warranty but also damage your unit making necessary the costly repairs to your unit by a professional. 

Additionally, it is important to securely affix all piping, plumbing and electrical wiring to outside walls and seal all exterior holes to avoid contamination by outside elements or insect life. 

Finally, the entire system needs to be pressure tested for leaks and efficient operation including safe electrical operation
