The Services We Provide
” Specialised Air-conditioning and Refrigeration Service Providers “
DUESIM INVESTMENT
Air Conditioning Services
Ideally air conditioning equipment should be serviced twice each year and here are some of the activities we do:
- Clean and inspect air filters.
- Clean coils. Dirty condenser coils raise the refrigerant pressure to a higher level than needed, increasing your electricity bill.
- Check electrical connections and measure the voltage.
- Check for refrigerant leaks on flares and service valves.
- Check controls and safety devices of the system to ensure proper and safe operation.
- Take and record temperature and pressures.


Refrigeration Installation
This process involves:
- Site Assessment: assess the site to determine the best location for the refrigeration unit, considering factors such as space, accessibility, and electrical supply.
- System Selection: Based on the client’s needs and the site assessment, technicians recommend appropriate refrigeration systems, which may include walk-in coolers, display cases, or industrial chillers.
- Installation: Technicians install the refrigeration units, connecting them to electrical and plumbing systems, ensuring proper insulation, and setting up any necessary controls or monitoring systems.
In House staff training
We train our staff the following tasks:
• follow plans and specifications to install, commission, service and maintain equipment
• drill holes, install mounting brackets and cut, bend and join piping
• install parts such as compressors, motors, condensers, evaporators, air filters, switches and gauges
• install and connect piping to refrigeration systems
• check that parts are installed, lined up and fit properly
• test systems for leaks and then fill them with refrigerant according to relevant standards and
regulations
• test refrigeration and air handling units and make adjustments to ensure they work correctly
• use computers to monitor systems and remotely adjust the operation of all equipment in a given
building.

Air-conditioning maintenance
- Clean and inspect air filters. – A restricted air filter can cause your air conditioning unit to waste energy and can shorten the life of the compressors.
- Clean coils. Dirty condenser coils raise the refrigerant pressure to a higher level than needed, increasing your electricity bill.
- Check electrical connections and measure the voltage. Faulty electrical connections can cause unsafe operation and reduce the life of major components.
- Check for refrigerant leaks on flares and service valves.
- Check controls and safety devices of the system to ensure proper and safe operation.
- Take and record temperature and pressures. An accurate record of your equipment’s vital data can indicate potential problems.
