Air Conditioning works to cool or warm your home, creating a comfortable living environment by filtering the air and removing the moisture which causes humidity. The principle behind air conditioning is simple. Two coils (one inside your home, the other outside) are connected by pipes filled with refrigerant. This fluid has the property of easily absorbing and rejecting heat, and is pumped through this circuit of pipes by a compressor. Two fans pass air over these coils.During the cooling cycle, warmed refrigerant circulates through the outside coil where it releases heat and cools down. It moves back inside, and is circulated through the indoor coil.The hot air inside your home is blown over this cold coil (and filtered and dehumidified at the same time) where it cools down and, in turn, cools your home. During this process the refrigerant warms up and moves back outside to repeat the cycle. (Your domestic fridge is a good example of this process.) When heating your home, warmth is generated by ‘reversing' the operation of the air conditioner.

Instead of expelling the hot air and circulating cool air it does the reverse - hence the term ‘reverse cycle' air conditioning. Where to locate your Air Conditioning unitTo ensure optimum performance, single package units or the outdoor section of split systems should have adequate ventilation and, if possible, be placed in a shady area.Direct sunshine and restriction of air access will reduce the air conditioner's performance.Adequate clearance from obstructions is essential to ensure that exhaust air is not re-circulated back through the outdoor coil. Saving EnergyGenerally the best temperature to set your air conditioning to is around 24 - 25°C in summer and 17 - 19°C in winter.You can save considerably on the amount of energy consumed for each 1°C of cooling or heating that you do without. For example when it's 35° outside, setting your air conditioner to around 25, rather than say, 22, can save a significant amount of energy without your system running constantly. Balance between comfort and efficiency of the system.

Shade your windows in summer with curtains, awnings, or shutters to reduce heat absorption by up to 80%. Heavy linen curtains with pelmets will also help trap heat in winter. This all helps in reducing the overall running costs of your air conditioning..au Caring for your Air Conditioning unitAir conditioning maintenance is always based on individual use, but in general you should check filters once a fortnight and replace the batteries in your remote control (where applicable) once a year. At the same time check the outdoor unit is clear of leaves, shrubs or dirt build up. To clean, simply brush or hose the outdoor coil. Please read the filter section below for more information. FiltersThe primary purpose of filters is to protect the indoor coil from dust build up which could reduce the overall performance of the air conditioner. It is important to regularly check and clean your filter. The majority of service calls are due to a dirty or blocked filter and in most cases a service fee is charged even if the air conditioner is under warranty.

Most air conditioners in the split range now have a specially treated additional filter that traps fine pollens etc which greatly helps people suffering from allergies.Ducted systems can now have electrostatic air filters fitted, which is the ultimate in home or office filtration.york ac unit coverAir conditioning maintenance is just one simple fortnightly operation. air conditioners at big lotsBecause the air filter in any air conditioner screens out dust and pollen particles, it should be removed regularly and washed. is there a tax credit for ac unitsThis simple operation is covered in the individual unit's instruction manual.All filters have a limited life span and will need replacing as over time they lose their dust holding capabilities.

We recommend replacing the filter in a ducted system yearly and in a split system every two years.

An air filter is a vital part of your home’s forced air HVAC (heating, ventilation, and air conditioning) system. Most homes have at least two filters that stand guard over your home’s air; their specific job is to remove bacteria and harmful particles, regularly cleansing the air. Why are filters important? 100% of the air in your home passes through a filter, typically twice every hour. Since clean, quality air filters keep the air in your home fresh, the people inside stay healthier.

A quality filter captures the harmful bacteria typically found in sneezes, coughs, viruses and molds, as well as pollutants like dust and car fumes. Clean filters also keep your HVAC system healthy—they enable it to run more efficiently, keep repair costs to a minimum, and reduce monthly energy bills. About half of your monthly energy bill is attributed to HVAC, and keeping clean air filters is the single most effective way to improve HVAC efficiency. Clogged filters make the HVAC work harder as it conditions your home, which raises your energy bill. (And if there are no filters, the coils will clog, which is even worse for your system.) How often should I change filters? We recommend changing filters at least every 3 months, but every 1 to 2 months will usually serve you better (especially if you have a busy lifestyle, family with allergies, pets in the home, etc.).

Regular filter changes cut 5% - 10% off your energy bill every month according to the Environmental Protection Agency (EPA). Where are air filters located? Air filters can be found inside the return vents in your home. These returns might be on the ceiling, wall, or in the system itself. Most homes have 2 or 3 returns inside the house, or alternatively, two 5” filters that go within the HVAC system itself. Typically the inside returns are more accessible, which makes filter changes easier in these locations. What about different sizes? Filters for returns come in all sorts of sizes—one size rarely fits all, even within one house. Dimensions range from 10” x 10” to 30” x 36.” Most (but not all) filters are 1” thick but occasionally, homes will have 2”–5” thick filters. How do I determine filter size? Sizing filters is easy. If there is an old filter in the return, the size should be listed on the side of the filter. Remember that each home typically has different sizes throughout, so you’ll want to check sizes at every return.
