Air Conditioning FAQ’s!

Should I repair or replace my faulty air conditioner? 

This is the million dollar question. There are certain things to take into consideration when trying to decide whether to repair or replace.

  • The age of the system?
  • How much is it going to cost to replace the system?
  • How much is the repair? Taking into consideration that other faults may occur after the initial diagnosed fault is repaired.
  • Warranty period on parts/repair compared to a replacement.
  • Wait time for repair – for some older system parts can be unavailable or even have to be sourced from overseas, and these can take 6-8 weeks minimum.

We would say it’s worth paying for a technician to assess the faulty system before making a decision.

During the heating cycle, why is white mist expelled from the air conditioners outdoor fans? 

During winter, most air conditioners defrost when the outdoor temperature is below 6°C. This mist is normal, it is only warm water vapour being expelled.

Does Running My Air Conditioner On Dry Really Save Me Money?

It depends on the air conditioning system and how hot or humid the room is. If the temperature isn’t extreme, say 26 degrees, but it is very humid, running the unit in Dry mode at around 23 or 24 degrees would be a wise choice. Of course, if you’re the sort of person who wants the temp to be 18 degrees or less, running on Dry would be of no benefit at all.

Why is water dripping from the unit?

Relax. This is simply normal condensation. This water can be channelled to a drain or garden bed, however it is only water after all so there really is nothing to worry about. Like rain water, it will quickly evaporate.

What is Reverse Cycle?

Reverse cycle refers to an air conditioner that can be switched to either heating or cooling depending on environmental conditions.
Most air conditioning units these days are reverse cycle.
Reverse Cycle Advantages:

• The most economical form of heating
• Heating and cooling from one main unit
• Unit stays cool to the touch, even when heating
• No exposed metal elements or flame
• They both dehumidify and filter the air you breathe

What is Zoning in Ducted Air Cons?

Zoning allows you to turn on and off the air conditioning in certain areas of the house. This is done through the use of zone controls in the ductwork in the ceiling space. For example, a two storey house may have an upstairs and downstairs zone, commonly called a day night zone.

A larger house may have four or more zones, and depending on the size of the air conditioning, there may be a restriction to how many zones can operate at any one time.

Other zone options include individual zones that are operated by temperature or your phone, tablet or computer.
Motion sensors call also be fitted to raise or lower the temperature when someone leaves the room.

What is the best temperature for an air conditioner?

Temperature should be set to 24 degrees on cooling and 22 degrees on heating. This is a good compromise between comfort and energy consumption. Every 1°C degree difference can increase running costs by up to 10%.

On a hot day, the amount of heat coming through every square meter of unshaded east, west or north-facing exposed window is similar to the heat put out by a small bar radiator.

Installing external shading for windows exposed to the summer sun is the smartest way to keep the sun’s heat out, increase efficiency of air conditioning and save on running costs. Look into insulating your ceilings to reduce how much heat enters your home during summer, and to keep your home warmer in winter.

What is an Inverter?

Traditional air conditioners run similar to a light. You switch the light on when you need it and off when you don’t. Inverter air conditioning systems are kind of similar to a car accelerator – when the energy to remove heat is required, an inverter ramps up. When the target temperature is reached, the inverter slows down.

This means that inverter systems result in a more efficient, energy-saving solution. Here are a few benefits of installing an inverter air conditioner in your home or business: Far cheaper to run than non-inverter air conditioners Less Noise Holds temperature more consistently Handles extreme climates better Target room temperature is reached quicker, whether heating or cooling Takes up less space A much higher heating capacity (up to 30% higher than non-inverter systems) Reliability! Inverter air conditioners are designed to last.

How does an evaporative air conditioner work?

A pump circulates water from the reservoir on to a cooling pad, which in turn becomes very wet. A fan draws air from outside the unit and forces it through the moistened pad. As the air passes through the pad it is cooled by evaporation. The key to effective evaporative cooling is ensuring that each of the cooling pads are completely saturated at all times during operation and that the systems fan & motor are sized and designed to deliver the appropriate airflow for the home.
