Recently had new tenants move into a property I have in Logan. The property was advertised as having air con, within 1 week they notified the property managers that the air conditioning system was no working. Managers have sent out their Air Conditioning Mechanic to inspect the system and he has diagnosed a faulty compressor and recommended that the system be replaced. Current system is 9 years old, he has quoted the installation of a 7.0kw Mitsubishi split system for $2491.50 which seems quite reasonable. I'm happy to have this replaced but just wanted to put it out to the PC community to offer any advice or share their own experiences as it is quite a large expense and right on Christmas. I have asked for a second quote in case the first one was misdiagnosed, if he comes up with the same fault and similar quote, I plan to go with the cheaper.
