To be proactive as a consumer, always confirm any installation, service or repair of your refrigeration or air conditioning systems is carried out by an authorised business like HeatNCool Tech and appropriately licensed technician.
The greenhouse effect is a term that describes how natural gases in the earth’s atmosphere reduce the amount of heat escaping from the earth into the atmosphere. The more these gases are released into the atmosphere, the more the earth will heat up. These gases act like a blanket around the earth — they allow the sun’s rays in to warm the earth’s surface, but they also prevent much of the heat from escaping. It is a bit like car windows on a sunny day — they allow the sun’s rays in to heat up the car, but prevent much of the heat escaping. That is why the inside of your car is warmer than the outside air on sunny days. Increases in the earth’s temperature can occur naturally as a result of climatic fluctuations caused, for example, by solar cycles and changes in the sun’s radiation. Human activity such as burning of fossil fuels (coal, oil and natural gas) and land clearing, however, are increasing the concentration of greenhouse gases in the atmosphere. These extra gases are like additional blankets around the earth. They allow the sun’s energy to reach the earth’s surface, but they prevent more heat from escaping. This means that the earth slowly heats up. This is called the enhanced greenhouse effect — it causes global warming and it is changing our climate.
Ozone depletion refers to the destruction of the ozone layer, the commonly used name for a part of the atmosphere about 20 to 30 kilometres above the earth. The ozone layer prevents the sun’s harmful ultraviolet radiation reaching Earth’s surface. Exposure to this radiation can cause skin cancer, eye damage and other health problems. Ozone depletion is caused by, amongst other things, chlorofluorocarbons and hydrochlorofluorocarbons (known as CFCs and HCFCs, which are also powerful greenhouse gases) and halons. These chemicals destroy atmospheric ozone. Ozone depletion has been observed by scientists since the late 1970s and in many parts of the planet more ultraviolet radiation reaches Earth’s surface than in the past.
If you decide to throw out an air conditioner that is no longer working, there may still be refrigerant inside the unit. If the unit is not disposed of properly, then the refrigerant may escape into the atmosphere, which will contribute to global warming. Before you place the air conditioner in your hard rubbish collection or take it to the tip, you’ll need to have the refrigerant ‘recovered’ from the unit by a licensed technician. The recovered refrigerant is forwarded by the licensed technician to Refrigerant Reclaim Australia (RRA) which is the sole facility in Australia approved to destroy refrigerants in an environmentally friendly manner. At HeatNCool Tech we can do this for safely for you.
In older units or units using older designs that still use R22, the refrigerant is both a synthetic greenhouse gas and an ozone depleting substance, which means that the environment is harmed in two ways through the release of these substances. If refrigerant is allowed to leak from your air conditioner during installation and maintenance, not only is the refrigerant doing direct environmental damage but the system will use more electricity as it works harder to deliver the same amount of heating or cooling with less refrigerant. This increases your electricity bill, shortens the life of your equipment and does unnecessary damage to the environment.
All servicing and repairs must be completed by a technician that holds a full refrigeration and air conditioning license. At HeatNCool Tech we have the correct qualifications to undertake the work required, including work involving handling of refrigerant. The reason that your unit may need servicing or repair could be due to an issue with the components that hold and/or transport the refrigerant within the unit, causing the refrigerant to leak out of the system. If a leak exists, all affected parts must be repaired or replaced before the unit can be refilled with refrigerant.
To answer this question, you will need specialist advice. Getting that advice is important because, if you buy a unit that’s too big, you’ve wasted money and it may operate inefficiently. If you buy a unit that’s too small, you won’t be as comfortable and you will probably spend a lot more on electricity bills than you need to because the unit is being overworked. Think about the space you want to heat or cool and then consult with a specialist from HeatNCool Tech.
The answer depends on a couple of things, including whether the unit is well suited to the room it’s installed in. Other things being equal, buy a unit with the highest star rating for the power output you need. The more stars it has, the more energy efficient your air conditioner is, the less it will cost you in power bills and the less damage you are doing to our environment. Compare the energy efficiency of units you are considering at www.energyrating.gov.au or look at the Energy Rating Label on the product. No matter how good your system is, or how well it has been sized to suit the room, it won’t operate efficiently if it is poorly installed. This will reduce the system’s cooling and heating capacity, increase your electricity costs and shorten the life of your system.
The most common residential split-system air conditioner is an air conditioning unit made up of two units — an outside unit, the compressor, and an inside air outlet unit, usually referred to as the “wall hung head unit”. The two units are connected by pipes that carry refrigerant. An alternative to the standard unit is the multi-split system, which has multiple indoor units connected to a single outdoor unit. A split-system air conditioner can be used for cooling and heating.
