Service & Maintenance
How often should I clean my air filters?
You should be checking your filters at least once every 3 months (quarterly). This of course depends on how often you use your system but better to be safe than sorry. A good reminder is every time you get your electricity bill have a quick look and after a year or so you will get a gauge on how often you actually need to be cleaning them.
You still however need to have your system serviced by a professional as we need to be cleaning the drain, drain pan and coils at least yearly is a residential situation.
What is done during a professional service by BS Air Conditioning?
During a service of a ducted or split system we will:
1. Check gas charge & temps
2. Clean filters, coils, return & supply air grills (as required)
3. Clean drains & drain pans and checked for blockages
4. Check electrical connections & current draw of components
5. Condition report of all duct work and all zone motor operation (Ducted systems only)
6. Advise if there is any signs of wear and tear or damage to system ect
Can I turn my air conditioner off at the power point or at the fuse box?
It is ok to switch the power off, particularly if you are away for long periods. Most units have a low wattage crankcase heater that keeps the compressor warm. Damage could occur if the compressor is cold at start-up. If you switch off your air conditioner, it must be turned on at least 12hrs before use.
How can I minimise my running costs?
There are three ways to help minimise the running cost of your air conditioning system:
1. Ensure you have the right system for your home and requirements.
2. Maintain your system by getting it regularly inspected and cleaned.
3. Run your system at 24 degrees during summer for efficient electricity use.
Can a dirty air conditioning unit make you sick or lead to legionnaires disease?
Only certain types of air conditioning systems are capable of providing the right conditions for legionnaires disease to survive. They are often found in shopping centres or very large industrial applications. Legionnaires associated in air conditioning cooling towers is also extremely low due to strict regulations that are enforced. This includes regular testing and biocide treatment under workplace health and safety laws.
However a poorly maintained residential or commercial system can also make you sick as it can encourage the growth of mould and other bacteria. Furthermore if your system is cleaned and maintained the filters can help to eliminate any other infectious disease such as colds and flu while the unit is running.
What size system do I need for my house?
Over-sizing is just as bad as under-sizing, so it’s important to use a professional to determine what size system you require. If you buy an air conditioner that is too small for the room it will not cool or heat adequately. If you buy one that is too large, the air conditioner will cool the room before it dehumidifies and this can leave you feeling clammy. We take into account what type of home you have, how many rooms need to be cooled, room size and ceiling height, and existing insulation. From that we can recommend what type of system would be suitable.
To get a rough estimate of what size you will need you can simply get the square metres of the room in question and times by 150 (watts)
example: Lounge room –
1. 4m x 6m = 24m sq
2. 24m sq x 150 watts = 3600 watts
3. 3600 /1000 = 3.6kw
What are the main differences between an Inverter and a Non Inverter?
Thanks to new and advanced technology, Inverter air conditioners are more economical to operate and much quieter than non inverter systems. They are smoother and more stable in operation, and can handle greater extremes in temperature. Inverter air conditioners can also reach the wanted temperature faster than non inverter splits. They are cheaper to run because they have the ability to be able to ‘ramp up & down’ depending upon the load put on them.
Can I install an air conditioning unit myself?
This is becoming a common practice for many DIYs and electricians.
The air conditioning and refrigeration industry is a licensed trade just like electrical plumbing or building. Our technicians undergo a 4 year apprenticeship and have to hold refrigerant license’s. This is also the difference between electricians who hold a install only licence. They may be able to install the system legally but if they come across a problem or the unit does not work for any reason the chances are they wont be able to fix it. Make sure you always employ a FULLY LICENSED company.
Under the Ozone protection and synthetic greenhouse gas emissions regulations, all work which handle refrigerant gases where there is a risk of emissions need a license to legally do the work. A licensed technician is the only one who can install an air conditioning system.
Installing yourself unlicensed can attract very hefty fines and will also void the manufactures warranty.
