IT IS IMPORTANT THAT THE AIR-CONDITIONING AND REFRIGERATION EQUIPMENT NEEDS REGULAR SERVICING TO PREVENT COSTLY REPAIRS AS A RESULT OF POOR PREVENTATIVE MAINTENANCE. 

Dirty filters on air-conditioning units and dirty heat exchange coils (inside- and outside aluminium coils or “radiators”) on air-conditioning & refrigeration equipment are the major cause in compressor failure (the heart of the unit).  When either of these components gets dirty the unit will feel as if it is not performing as it used to.  This in return causes the compressor to overheat and by running the unit in these conditions will cause the compressor to either seize or burn out its windings.

  

With electric connections and controls starting to worn as time goes by various other problems starts to occur such as burning of the fan motors, faulty capacitors and the extended running of the cooling/heating cycle which result in costly electric bills. 


SERVICES PROVIDED: - (AIR-CONDITIONING & REFRIGERATION) 


FILTER SERVICE

As the name suggests this is mainly nothing more than a filter service where the filters are removed and cleaned.  Where applicable the condensate drain outlets are cleaned and all blockages removed with a blower.  While on site the technician will check the unit by sight, feel and sound to determine if there are any possible faults.  This type of service is recommended monthly.


NORMAL (MINOR) SERVICE: 

This is a basic filter service with extras.  The equipment is checked with gauges and tested with test equipment to ensure that everything is running satisfactory to the manufacturer’s specifications.  Equipment is tested for possible gas leaks and all electrical connections are checked and tightened.  The condensers are washed with water where possible. Where applicable the condensate drain pan is removed and cleaned to ensure flow-free water outlet.  This all gives us a chance to prevent any problems that might occur which could cause damage to the unit.  This type of service would be recommended Bi-monthly in some areas or as often as agreed by the client.

 

MAJOR (CHEMICAL SERVICE):

This is basic a normal (minor) service with a few extra’s.  The equipment to be serviced is removed and stripped.  The heat exchangers (coils) are cleaned with chemical cleaner and high-pressure water.  The rest of the equipment is washed before it is re-assembled.  Electrical components are sprayed with a silicone spray to prevent rust forming on the contacts to ensure good electrical connection points.  All mechanical parts are inspected and adjusted where applicable.  This service is carried out twice a year, depending on where the equipment is situated.

 The same service applies to refrigerant equipment. 

 

SERVICES PROVIDED (VENTILATION)


INSPECTION & ELECTRICAL:

All ventilation type systems will be inspected by feel and sound at first.  This is to test and see if the fan shaft is turning freely and without any noise.  The fan or motor which drives the fans in some cases will then be switched on to determine if the fans are still in good working order.  Fans, which are pulley driven, will have their bearings lubricated and their fan belts checked and adjusted if necessary.  During major servicing the drive motors will be stripped and cleaned and the resistance of the field windings measured to determine if the motor is still operating correctly.  All electrical terminals will be cleaned and the connection screws tightened.

 

SERVICES PROVIDED (ELECTRICAL)

 

INSPECTION & TESTING:

All electrical components will be visibly checked and manually operated whilst the power is disconnected to see if the contactors move in/out without being sticky.  (Sticky or worn contactors could result in phase failures and/or incorrect control operation and this could lead to expensive repair costs later).  Safety controls (pressure switches, overloads, motor protection relays …etc) will be checked and tested to ensure protection of your equipment. 

We deliver a broad range of services that guarantee measurable results and a positive impact on your business.
