What happens if the unit is DOA?

If you have NOT purchased the air conditioner from EZYAIR and EZYAIR install it to discover that it is DOA (dead on arrival).

1. EZYAIR will invoice you for the original installation
2. Invoice you for decomissioning the faulty unit
3. Invoice you for re-installing the replacement unit.

You will then have to chase the retailer who you bought it off, to pay for EZYAIR's services. 

As most bulk stores run on such skinny margins, it is likely that you will have fight on your hands to get any money from them to pay for the removal and re-installation of the faulty unit.

~~~~~~~~~~~~~

If you have purchased the air conditioner from EZYAIR and the unit is DOA, EZYAIR will remove the unit and install the new unit, free of charge.

What happens if the unit is damaged in transit?

OK - so you've bought the air conditioner from a bulk store and EZYAIR open it to discover that is has been damaged in transit and advise you the stock is damaged.

1. You have to pack the stock up and wait for it to get picked up.
2. You need to wait for the retailer to authorise a replacement.
3. You have to wait for delivery of the replacement unit.

After all this time, you will have to wait until EZYAIR are available to install your air conditioner (usually a matter of weeks during summer or winter).

~~~~~~~~~~~

If you have purchased the air conditioner from EZYAIR - and they discover it has been damaged in transit - EZYAIR will rush a new unit to your place - and complete the installation on the same day.

What happens if the unit stops working during the warranty period?

If you have NOT purchased the air conditioner from EZYAIR - and it stops working during the warranty period (anywhere up to 5 years later), you need to contact the retailer.

Once you contact the retailer, they will tell you who to call for a warranty claim. You then have to find and produce your proof of purchase and contact the service agent.

You then call the service agent who will come to your home and establish the problem. The service agent will then leave - and return with the part to repair the air conditioner.

~~~~~~~~~~~

If you have purchased the air conditioner from EZYAIR:

• Call 1300 EZYAIR (1300 399 247) at any time during the warranty period and a technician will either diagnose the fault over the phone - or send a technician out FREE of charge to establish the fault.
  
• EZYAIR will either rectify the fault when they come out or book the service call for you.
  
• EZYAIR will have the date of purchase, model number, serial number on file for you, so you don't have to find a thing.
  
• EZYAIR will then do everything they can to expedite a satisfactory soloution for you.

Conclusion

While EZYAIR understand that some customers will purchase from bulk stores - and we are happy to install the units for them - we hope this information gives customers the right information to make an informed decision when purchasing their air conditioner.

How to calculate energy efficiency of an air conditioner

As you can see from our blog on how to read an energy label, a split system air conditioner will ALWAYS output more energy than it consumes.

So how do we work out exactly how efficient a split system is, so we can compare products?

Well, there are two calculations:

1. This calculation in cooling mode is called EER (Energy Efficiency Ratio)
2. This calculation in heating mode is called COP (Coefficient of performance).

How to calculate EER (Cooling efficiency)

• In cooling mode, the air conditioner consumes 1.58kW and outputs 5.2kW.
• Divide the output (5.2kW) by the input (1.58kW).
• Therefore this split systems EER is: 3.41 to 1.
• This means the air conditioner will output 3.41 times as much energy as it consumes!

How to calculate COP (Heating efficiency)

• In heating mode, the air conditioner consumes 1.63kW and outputs 6.7kW.
• Divide the output (6.7kW) by the input (1.63kW).
• Therefore this split systems COP is: 4.1 to 1.
• This means the air conditioner will output 4.1 times as much energy as it consumes!

This sounds great, but how do I compare products?
The EER and COP readings are the easiest and fastest way for you to compare energy efficiency between air conditioners. Most reputable split system manufacturers include the EER and COP readings on their promotional material. Grab the most information you can get, and compare COP and EER's between products.

Conclusion
This co-efficiency is typical of most split system air conditioners and is the reason why split system air conditioning is one of the most energy efficient forms of heating and cooling available on the market today.

How does a split system air conditioner work?

Split system air conditioners operate on a vapour compression refrigeration cycle. This is a thermodynamic process of refrigerant changing state (from a vapour to a liquid to a vapour again) which enables air conditioners to heat or cool.

Figure above: Condenser = 1, TX Valve = 2, Evaporator = 3, Compressor = 4.

1. Super Heated Vapour
We will start the example just before the compressor (No. 4), on the right hand side, where the refrigerant entering the compressor is a saturated vapour. After it goes through the compressor - it's compressed, so it's pressure and temperature of the saturated vapour goes up and it becomes a super heated vapour.

2. Sub Cooled Liquid
The super heated refrigerant is then forced through the condenser coil (No. 1), which has a fan blowing over the coils. This enables the heat to be released from the refrigerant. This process of cooling the refrigerant through the condenser brings the temperature of the vapour down and it changes state, to a sub cooled liquid.

3. Saturated Liquid
Before this sub cooled liquid reaches the evaporator (No. 3), a component inside the evaporator called the pressure release valve ( or TX valve - No.2) abruptly releases the pressure of the refrigerant. This abrupt pressure loss causes flash evaporation of some of the refrigerant and this brings the temperature of the refrigerant down again. The refrigerant is now a sub cooled, saturated liquid.

4. Saturated Vapour
This saturated liquid travels through the evaporator coil (No. 3). The evaporator fan sucks air over the coil and the refrigerant absorbs the heat from the coil. This causes the temperature of the refrigerant to go up, and the temperature of the air to go down. This heat exchange causes the refrigerant to boil and evaporate into a saturated vapour (keep in mind that R410A boils at minus 48.5 degrees, so it's still super cold).

And the Cycle Continues
The saturated vapour then travels through the refrigerant piping back to the compressor, where the refrigerant (in a vapour state) is compressed into a super heated vapour and the cycle continues.

Post Script
If you are learning about refrigeration for the first time. Please keep in mind that it took a colleague of the author, who has a Ph.D in plasma physics, magnetohydrodynamics & astrophysics around a year to get his head around vapour compression refrigeration... so don't sweat it if it doesn't make sense right now!
