Your Air Conditioner

Q- Why isn’t my air conditioner as cold as it used to be?

In most cases the coil is probably dirty, especially if it has never been cleaned. If the temperature falls down a few degrees after cleaning, then the solution was a simple clean and service. If not, it may require refrigerant.

Q- Why isn’t my air conditioner blowing as hard as it used to?

It is probably very dirty, which prevents the airflow from smoothly passing through. Once the blower fan has been properly cleaned, the airflow will generally double.

The drum has up to 400 small fan blades on it, and when the leading edge of each blade gets a buildup of dirt attached, it simply becomes inefficient. If the drum is turning very slowly, then you may need to replace the fan motor.

Q- Why is my air conditioner “huffing” quite badly?

This is generally due to very dirty filters. If you neglect to clean your filters regularly, you will gradually choke your air conditioner!

Q- Why does my air conditioner rattle when I turn it on?

Usually, this is due to the blower fan being out of balance. A buildup of contaminants on the drum will cause this over time. A service will fix the problem.

Q- Why does my air conditioner smell when I turn it on?

A smelly air conditioner is a dirty air conditioner. A service and proper clean will rectify the problem.

A really bad odour can be caused by small critters crawling up the drain and not being able to get out, sometimes to the point of dying in the head unit. A service and clean will fix this problem.

Q- Why is my air conditioner blowing hot air instead of cool air?

Firstly, check to see that your remote is on the right mode. If it is, you will need a technician to take a look at the gas level and/or possibly the compressor.

Q- Why isn’t my air conditioner switching on at all?

If your remote is in working order (check if the batteries are functional), then you will need to switch it on manually. You will generally find the manual button up near the electrical panel. If you are unable to locate it, call a technician. If it switches on manually then you need to have a technician check the receiver board.

The HydroKleen Service

Q- What is the difference between a HydroKleen service and a traditional cleaning by an air conditioning tradesperson?

Firstly, there is no regulation defining what constitutes an air conditioning maintenance service. Therefore, while some companies hold certifications, industry standards do not exist. 

An air conditioning technician will generally use the traditional “strip and clean” method. This involves removing, in most cases, the head unit, dismantling it and then cleaning it externally. This process can take up to three hours and is simply not cost effective, nor time efficient at today’s hourly rates.

The most commonly used method is for a technician to squirt some alkaline or acidic based chemicals onto the coil, or evaporator, and hope that it will be flushed away by the condensate when the head unit is switched on. However, if there is no humidity, there will be no condensate.

HydroKleen developed a unique technology powerful enough to clean every part without damaging them. Moreover, the cleaning agent we use is safe for both the environment and your health. Finally, we guarantee to leave your home as clean as it was. We provide a prompt, courteous, professional and efficient service.

Microbial Contamination

Q- How does a typical home air conditioning system work?

A typical system functions as follows: air is drawn from the room through a return grill and passes through an air filter and into a furnace (or air handler). Inside the air handler is the circulating blower and a heat exchange coil commonly called the evaporator. The evaporator is cold and thus removes heat from air that blows across it. The cooled air then returns to the room via outlet grills. Meanwhile, water deposits on the evaporator’s surface. The moisture falls into a drain pan under the evaporator and drains through a pipe out of the system.

Q- How does the air conditioning system inside a home can become a source of microbial contamination?

The air drawn into a system contains dust, much of which is made up of biological spores and other organic particles. Even the best filters capture only part of this material, while the rest falls out of the air stream onto the heat transfer surfaces. It combines with the water and the spores germinate and grow rapidly, or amplify.

Q- Does microbial contamination in my air conditioning system impact the quality of the air in my home?

Yes. Contaminated air conditioning systems can become breeding grounds for mould, mildew and other sources of biological contaminants. These contaminants are then distributed throughout the home. System components can act as direct or indirect sources of particles and/or volatile organic chemicals (VOC’s). 

Of greatest concern is biological growth and bio-aerosol generation, most of which are potential allergens. Airborne allergens in the home constitute one of the hardest types of allergens to avoid. Unfortunately, heating and air conditioning systems are excellent harbours for mould, and, moreover, quickly become an efficient distribution network.

Q- How can the growth of these biological contaminants be prevented?

Keep your system clean and treated with a broad spectrum antimicrobial, which does not only kill microorganisms (i.e. mould, mildew, fungi and bacteria) in the system but will inhibit their growth for up to six months.

Q- Can keeping my system clean and free from growth provide other benefits?

If you clean and flush your system regularly it will operate more efficiently, use less power and last longer.

Q- Why would a growth-free system last longer?

Most corrosion in heating, ventilation and air conditioning systems is caused by sulfuric acid secreted by common bacteria which chemically combines sulfur from the air with hydrogen and oxygen from water.
