Q. My air conditioner isn’t as cold as it used to be
A. The coil and or filter are probably dirty – it’s essential to keep your air conditioning system regularly cleaned, serviced and if necessary repaired. We will also check if your unit requires refrigerant.
Q. My air conditioner isn’t working as well as it used to
A. If the air isn’t blowing so efficiently as it used to, the air flow may be inhibited by dirt on either the coil or return air filters. Once the Evaporator coil, air filter and blower fan (drum) has been properly cleaned the airflow can double of not triple. Each drum can have up to 400 small fan blades and if the leading edge of each blade gets a build-up of dirt attached it becomes inefficient. A drum turning very slowly can be a sign that you need to replace a fan motor.
Q. My air conditioner is making an annoying noise
A. This is generally due to very dirty filters. If you don’t clean your filters regularly, this is bad for the health of your air conditioner and for you.
Q. Why does my air conditioner rattle when it’s turned on?
A. This may be the blower fan (drum) out of balance due to a build up of contaminants on the drum – a clean will solve the problem.
Q. My air conditioner is giving me hot air instead of cool air
A. First of all, make sure that your remote control is set on the right â€œMODEâ€. If it is, then you will need one of our Air Conditioning Wizards technicians to check the gas level or the compressor.
Q. My air conditioner won’t even switch on
A. First check your batteries in the remote control, and make sure the power is turned onto the unit outside, If your remote won’t work, try switching it on manually. The manual button is usually found near the electrical panel. If you can’t locate it, call a technician. If it switches on manually then our technician will check the receiver board.
Q. How does a usual home air conditioning system work?
A. Air is drawn from the room by the blower fan (drum) and through a return grill, and then passes through an air filter to a heat exchange coil called the evaporator. The evaporator is cold and thus removes heat from air that blows across it. As well as removing heat, water deposits on the evaporator surfaces and the cooled air returns to the room through outlet grills. Moisture falls into a drain pan under the evaporator and drains out through a pipe.
Q. How can the air conditioning system get contaminated with microbes?
A Air drawn into a system contains dust including biological spores and other organic particles. Even the best filters capture only part of this material – the rest falls onto the heat transfer surfaces where combines with water. Spores then germinate and grow rapidly, or â€œamplifyâ€.
Q. Does microbial contamination in my air conditioning system impact human health?
A. Yes – this can be very dangerous for your health. Contaminated air conditioning systems are breeding grounds for mould, mildew and biological contaminants and then distribute these pollutants through the building. These are sometimes known as volatile organic chemicals (VOC’s). Biological growth and bio-aerosol generation are potential airborne allergens which are one of the hardest types of allergens to avoid. Regular, professional cleaning and maintenance by Air Conditioning Wizards ensures the safety of your air conditioning.
Q. How can you prevent the growth of these biological hazards?
A. When you keep your system clean and treated with a broad spectrum antimicrobial, this kills microorganisms including mould, mildew, fungi and bacteria and inhibits their growth for up to 6 months.
Q. What other benefits do I get from keeping my system clean?
A. When you clean and flush your system regularly it operates more efficiently, uses less power and lasts longer.This is because most corrosion in systems is due to sulphuric acid secreted by common bacteria that chemically combines sulphur from the air with hydrogen and oxygen from water.
Q. How do I know which air conditioning system to install?
A. Air Conditioning Wizards’s experience enables us to estimate exactly the system you need for your comfort, health and budget
