Fixed speed units as the name suggests uses a fixed speed compressor that cycles on and off as necessary whilst an inverter unit makes use of a digital scroll compressor that does not cycle on and off but instead runs at varying speeds as necessary.
It has been calculated that the nature of the digital scroll compressor can amount to a saving in power consumption of between 40 and 60% depending on extent of use.
Whilst the inverter units are considerably more expensive to purchase, the resulting power saving should ensure that the difference in cost will be reclaimed within 2 years once again depending on the extent of usage.
Most manufacturers insist on a service interval of no longer than 6 months for warranty purposes on new units.
I would therefore assume that this should be standard practice throughout the life span of the unit.
This is however a guideline only in certain circumstances depending on the environment, (amount of dust or pollution in the air) it may be necessary to service more regularly. A brick factory for example may will need to have their units serviced every 3 months to keep them in good working condition.
Regular servicing of units will optimize performance, thereby saving on power consumption and increase lifespan of unit as well as POSSIBLY preventing costly breakdowns from occurring.
It should not be necessary to regas unit at all if unit is installed properly, however flaring and connection of pipes if done correctly will mean that no leakage should occur.
However, given that this is done by a technician on site there is no guarantee that human error will not occur from time to time in which case this needsite to be repaired.
Also bear in mind that pipe failure and general wear may also occur resulting in leakage which should also be repaired as soon as possible as unit cannot be topped up repeatedly as it is not legal to release the gas into the air. If I am caught doing this I can be heavily penalised with a hefty fine.
If less than 20% of the gas in the unit is lost it is possible to top up the gas once. If the gas has already been topped up once or more than 20% of the gas has been lost then due to the nature of R410 gas, the unit will have to be repaired and the gas will have to be recovered from the unit and weighed in from scratch. The reason that the gas cannot be topped up more than once is that due to the nature of R410 gas (it is a mixture of gasses) the performance of the gas will be affected, affecting the performance of your unit.
Yes, we supply and install various brands of air conditioners depending on preferences or budget as well as taking into account the environment in which the air conditioner will be used. The frequency of use will also determine whether you need to purchase a fixed speed or inverter unit. We also install units purchased from chain retailers (Game; Makro; Builders Warehouse etc) however this is not the preferred option as this complicates warranty claims and sometimes results in clients purchasing incorrectly sized units, therefore it is recommended that you contact us to do a site visit before purchasing a unit.
No you can use your air-conditioner on heating to heat a room quickly and efficiently. Using an air-conditioner on heating is less costly than using an electric heater as it uses less electricity than an electric heater.
