Refrigerant gas is used in air conditioners to produce heat and cooling. If there is a refrigerant gas leak, then the air may not be as cool or warm as it should be. Refrigerant gas leaks can occur, sometimes due to poor installation, others because a system has been knocked or bashed accidentally and the seals become broken. You may not be aware that this has happened until the system is not working and the majority of the refrigerant gas has leaked out, which could happen over a matter of months.

Reverse cycle refers to the single system that can provide both heating and cooling.

This can happen when the system reverts to HEATING operation after DEFROST operation. Moisture generated by the defrost function becomes steam and is released.

Inverter systems have a compressor that can vary its speed, which means the same result can be achieved with lesser effort. Inverter systems are cheaper to run quieter and prolong the life of the system.
The benefits include:

  • Up to 40% saving in running costs
  • Quieter operation
It is important to get the right size system. A system that is too small will have to work too hard and for too long. By having a system that is too small, it will reduce the life of the system and increase the running cost. To be sure you purchase the ideal system to suit you we recommend you consult with our qualified staff.
Regular maintenance is essential to keep your air conditioner operating at optimal levels.
Benefits include:
  • Reduce running cost.
  • Maximises the life cycle of your air conditioner.
  • Reduces your air conditioner breaking down.
  • Check to see if there is a power failure. Wait until power is restored. If a power failure occurs during operation, the system automatically restarts immediately after the power supply recovers. Check if a fuse has blown or circuit breaker has tripped.
  • Change the fuse or reset the circuit breaker; switch off and leave for 20 minutes then switch back on again. If the system fails again or there is still no power call Mammut Air Conditioning for repair.

Not only the size of the area that needs to be conditioned but also the amount of existing glazing (glass) and the heat load generated from the number of people occupying the area will determine the size (rating) of the system required. Thompson Cooling recommends a site visit by one of its sales consultants to determine the correct system sizing for your home or office. If a site inspection is not possible then floor plans will aid in the preparation of your quotation.

A ducted air conditioning system is designed to air condition more than one room within your home. The indoor fan coil unit is situated manually in the ceiling space and is connected to the outdoor condensing unit. Individual outlets are situated in each room with the air conditioning controlled by a central controller. Unlike the ducted system, the split system is primarily designed to air condition only one room. If you are looking for an even flow with air conditioning throughout the entire home, our air conditioning installers recommend a ducted system

Some air conditioning systems are controlled manually, others by infra-red remote control. Split systems, for example, have an infra-red remote control with functions to control temperature settings, timers, and humidity levels. Ducted systems are controlled generally through a centrally located wall-mounted controller. This unit controls temperature settings, fan speeds, humidity levels and timer functions.

The most energy-efficient method of heating and/or cooling your home or office is reverse cycle air conditioning. Essentially, operating costs are determined by how long the air conditioning system is running and the size of the area to be cooled. It is essential that the correct size unit is installed. An undersized unit will be significantly more expensive to run taking longer to heat and cool the area effectively.

Ducted systems can be designed so that only parts of the house (zones) can be air conditioned at a time. Check that the zone switch is turned on.
This applies to the installation of a ‘split’ system. If the installation is back-to-back, the indoor unit is positioned on the interior wall adjacent to the outdoor unit, reducing the length of the connecting (refrigeration) pipe-run between the two units.

Ventilation systems can be categorized as one of four types: exhaust, supply, balanced, and heat-recovery.

The main difference between the two types of fans is their application. While a ventilation fan works to bring clean air into an enclosed space from an outside source, an exhaust fan removes pollutants from the indoor air in a home or commercial space.

Exhaust ventilation systems work by depressurizing your home. The system exhausts air from the house while make-up air infiltrates through leaks in the building shell and through intentional, passive vents. Exhaust ventilation systems are most appropriate for cold climates.
