In our experience, there’s no real “rule of thumb” that can be applied to air conditioning sizing. The unique properties of your home and the placement of your air con needs to be carefully considered.
Essentially, you need to ensure your unit has enough kW to cope with the hottest day of the year.
The very best way to accurately determine what size air con you need is to have a trained technician conduct an inspection of your home and make a recommendation.
That really depends on your air conditioner and how hot or humid your room is.
If the outside temperature isn’t extreme, let’s say it’s around 26 degrees, but it feels very humid, running your unit on dry mode at around 23 or 24 degrees is the best way to go.
However, if you’re the sort of person who wants the temperature to be 18 degrees or less all the time, running your unit on dry mode doesn’t offer any cost-saving benefits.
Relax! This is simply part of the normal condensation process.
The majority of the water caused by the condensation will drain away out of the inside unit and down the drain pipe. You may notice a small puddle on the ground from time to time which will eventually dry up on a hot day.
However, if you notice persistent dripping even when the air conditioner isn’t turned on, then this is likely a sign of a problem and needs to be checked out by an air conditioner professional. It may be a case of a blockage in the drain pipe, causing water to build up inside the unit, instead of flowing away freely to the drain.
Try the “organic” approach. You can do things like add curtains and blinds on all windows facing east and west. If possible, delay heat-generating activities, such as cooking & baking, until the evening on hot days.
You air con will also work most efficiently when you set it to a reasonable temperature. The general consensus is the following:
Also, you can save considerably on your power bill for every 1°C of cooling or heating that you do without (around 10% per degree).
For example, when it’s 36° outside, setting your air conditioner to around 25°C, rather than say, 21°C, can save a significant amount of energy without your system needing to run constantly. Because it’s so hot outside, 25°C will seem comparatively cool and you won’t be wasting power trying to make your home super-cool.
Relax! This is normal. It is simply caused by the cool air coming out of your air con meeting the hot humid air in the room and as a result forming water vapour.
The usual reason for this is that mould and mildew has accumulated inside your unit due to a lack of maintenance.
However, the smell could also be caused by a deceased gecko or rodent having crawled inside your unit.
If you are noticing a bad smell coming from your air conditioner, it’s best to arrange for a technician to check it out.
This usually only happens in winter when the unit is in heating mode. What happens is that your air conditioner first checks the temperature of the refrigerant (Freon) which is often in liquid form when it’s colder. Basically, the lower the outside temperature, the longer it takes for your unit to start up.
You can if you install a multi-split system. This is where multiple internal units are all linked to the one external unit, rather than having one internal unit for every external unit. This option is ideal if you don’t have the budget or ceiling space for ducted air conditioning.
Only on hot dry days and nights. However, when the weather is particularly humid, you should set the fan speed on low for increased comfort. This will help to remove more moisture from the air and actually make your home cooler.
When you purchase and install an air conditioner with Acer Services, you’ll automatically be covered by two separate warranties:
2. The manufacturer’s warranty which is usually for 5 years, depending on the brand
But for your ultimate piece of mind, we also offer a free extended installation warranty for both domestic and commercial air con units:
No, even though they share the name and were once sister companies, Mitsubishi Electric broke away from Mitsubishi Heavy Industries in 1921. They are now direct competitors, pushing each other to produce the most innovative air conditioners on the market.
In our experience in dealing with second hand units, definitely not. In most cases, second hand units are between 5 and 10 years old and probably obsolete. The filters will be worn and/or dirty and parts will be difficult and expensive to find.
For total peace of mind, it is much better to buy a new air conditioner and take advantage of the manufacturers’ warranty.
Yes. Dust and dirt build-up on the indoor coil is the single most common cause of poor efficiency in air conditioning systems. Getting a regular service for all your air conditioners will ensure that your system works efficiently when you need it most, and will continue to work for many years to come.
