It is essential to have Evaporative Coolers cleaned and flushed prior to first start up of the season. EVERY YEAR.

Let’s explain WHY

Once summer is over and you switch off your system for the last time, over the course of the year, bacteria will start to form inside the sump of your unit.  Often insects and rodents use Evaporative Coolers as a home during Winter as well.

When you switch on your system for the first time all that dirty, bacteria contaminated water will be pumped around your system. Particles of that contaminated water will be pushed throughout your home or workplace – directly into the airways of you, your family, co-workers or friends.

Not only can this cause serious health issues, it can also create an unpleasant odor in the areas it is serving.

Here you can see what the sump of a dirty Evaporative Cooler looks like.

Do you want to breathe in that water?

Our technicians are trained to chemically clean and flush your system.

This will ensure that your Evaporative Cooling system will provide you with CLEAN, SAFE and COOL air this Summer.

When our technicians service your Evaporative Cooling system, you can expect the the following tasks to be carried out.

• Remove water pads and clean off dust, dirt, debris etc.
• Check and tests operations of water pump (clean strainer).
• Check float valve and balance valve to correct water level.
• Check operations of solenoid valve.
• Clean of flush system walls of sump.
• Check roof flashings for leaks
• Check drain for blockages etc.
• Check that water distribution across pads is even and correct.
• Check airflow.
• Test fan motor.
• Check Vee belt (if required) and replace if needed.
• Test electrics, tighten where required and make sure electrical enclosure remains waterproof.
• Test isolation switch.

A Split System needs to be maintained at least once a year in your home or at least twice a year if installed in your office, factory or server room.

Let’s explain WHY

Filters

Your system continually cycles air through the filters and over time they build up with dust and contaminants.  To prevent the filters becoming blocked, and as a result compromise the quality of the air you are breathing, they need to be cleaned.  Blocked filters cause the system to work much harder, greatly reducing the efficiency of the system as well as increasing your power costs.

Refrigerant

A split system is filled with refrigerant. If your system has a small leak and is losing refrigerant, the efficiency of your system will begin to decrease.  Again, resulting in increased power costs to you.  If this refrigerant continues to leak over a long period of time, the increased pressure on the compressor will cause it to run hotter and may result in internal damage.  If your compressor fails, you are looking at a very costly repair which could have been prevented with regular servicing.

Our technicians will always check the refrigerant pressures and system supply air temperatures to make sure your levels are correct.

Electrical components

Roughly half of your split system is made up of electrical components.  These need to be checked at least once a year to ensure the connections are tight and there is no sign of burnt or hot wiring.  An electrical connection over time can become loose due to the basic vibration a system has during normal operation.

A loose wire can cause catastrophic damage if it “shorts out” and results in a fire within your system.  System fires can often lead to your home or workplace burning down.

When our technicians service your Split System, you can expect the the following tasks to be carried out.

• Check all return air filters.  Remove and clean where required.  Report on worn filters requiring replacement.
• Check indoor fans, motors and vee belts.  Lubricate shafts and seals as required.  Replace vee belts if worn or damaged.  Check fan rotation and blade balance and alignment. Record and report any faults.  Ensure spare vee belts are left at fan chamber at all times.
• Check all drains for blockages, this includes internal drain pans.  Ensure that drains have adequate fall.  Test drains by running water through the system.  This includes drip trays if fitted.
• Check indoor pipe connections are tight.  Check for signs of oil around flares.  Ensure that the pipework is insulated over flares to prevent condensation leaks.
• Check airflows and air balancing throughout supplied area.  Check temperatures are correct.
• Check that thermostats are calibrated correctly, temperatures are set to a comfortable level and system is programmed to client’s request.
• Visually inspect all equipment.  Check for rust, damage, loose covers, missing screws, foot mounts, dints in coils or damaged fins.
• Check operating pressures and supply air temperatures.  Ensure refrigerant levels are correct.
• Activate reversing valve. Check magnetic coil. Ensure unit switches correctly from cool to heat.  Run system through cycle.
• Check condenser fans. Ensure they are balanced and operating correctly. Check that safety grilles are in place over fan blades.
• Check all electrical connections.  TIghten as required.  Report any electrical hazards immediately.
