Good Air as a company that specialises in HVAC maintennace, offering trouble shooting and repairing services for ‘problem’ air conditioning systems, we see with the many different and bespoke air conditioning systems installed.
A disturbing trait is emerging where VRF systems show signs of trouble, in that when things go wrong, they tend to go from bad to worse over relatively short timeframes and can render complete systems unusable well before expectations. Trust your HVAC maintenance and repair to professionals.
Most of the VRF system has self trouble analysis function, and when system in error status, the outdoor unit or indoor unit can display the error code. The difficults is that the same error can be cause of diffirent reasons and here VRF repairing should be as per desision of HVAC technician. Somitimes the system does not showing any error, but VRF not working properly. Here It requirs some special equipment and tools to reqtify the problem.
If VRF repairs, such as a compressor or other refrigeration component replacement is required or remedial work such as relocation of an indoor unit is required; all of the measures relating to a new installation will be required – there are no shortcuts without consequences.
One significant difference from new build installations is that there is likely to be significantly more pressure to get the system back up and running due to the building occupants complaining of no air conditioning. Thats why it very important to have qualified technicians and professional VRF repairing tools to comleate all repairing works within minimized time frame.
Variable Refrigerant Flow (VRF) systems maintenance are one of the most difficult. A disturbing trait is emerging where VRF systems show signs of trouble, in that when things go wrong, they tend to go from bad to worse over relatively short timeframes and can render complete systems unusable well before expectations. It is heighlyy important to maintenance VRF system by professionals.
Given that these systems are relatively expensive and the cost and disruption associated with early replacement is very high we advice to trust your VRF installation, maintenance and repairing to professionals.
Whats going wrong in VRF maintenance:Given that these systems are relatively expensive and the cost and disruption associated with early replacement is very high we advice to trust your VRF installation, maintenance and repairing to professionals.
There are several areas we see as possible contributors to early failure: Obsolescence of VRF systemSome of the earlier VRF systems introduced 10-15 years ago are now effectively obsolete, with parts being increasingly expensive and difficult to source. Where parts are unavailable or expensive and the system is reliant on R22 refrigerant, the point of no return is quickly reached, leaving the only viable option for the building owner to replace the system.
Poor installation of VRF systemRefrigerant leaks, improper evacuation, poor or no pressure testing and the lack of nitrogen purging during pipework welding can all result in premature failure of the systems.
Poor maintenance of VRF systemSome of the contributing factors are:
It is very difficult to determine if refrigerant levels are correct by simply connecting refrigerant pressure gauges, due to the widely varying operational states that can exist as the indoor units all behave independently. Where a loss of refrigerant has been detected, the only sure way to re-charge the system with the correct volume of refrigerant is to decant all of the refrigerant out of the system and replace it with a known (weighed) quantity. Time and cost pressures often mitigate against this practice.
The right peopleVRF systems are complex and requiring very high standards of design, installation and maintenance. Professional vrf maintenance companies may be more expensive than typical service providers, but these costs fade into insignificance compared with the costs attached to premature system failure.
If the above guidelines are followed, we remain optimistic that a life expectancy in excess of 12-15 years could be achieved.
