Fujitsu High Static Single Phase R32 (HP)

Starting with a Pro, it’s great in summer, the whole house cools quickly as an air-conditioning system should do. In winter though, the heating is not as great compared to other systems available. It does quickly take the chill away, but can take a… Read more

while to really heat up. The heating system would take at least an hour to climb 1 degree and it wouldn’t reach the set temperature of 22 degrees Celsius. When it got to 19-20 degrees, it started to blow cool air over our heads (very uncomfortable during winter days). It was explained to us that the system will back off when it gets near the set temperature when the fan is set on Medium. So, in winter when it’s really cold, that weak air flow will become cold as well (makes no sense to me why they design it like this for heating). The only way to keep it blowing hot air is to set it on high, this would eventually lead to the house heating past the set temperature where it wouldn’t self-turn off when it reached temperature. The only thing we could do was set it on a timer to run for 2-3 hours and switch it back on if it was still cold. Not very efficient, effective or automatic and would be very expensive to run if we let it run its climate control way. The unit also has a defrost mode, where it can take 20mins or more to start heating, or stops midway to run the defrost mode.

Install Pitfalls: After install, check that the ducts have been taped properly. We found that some of the ducts had not been properly taped up or at all, one duct was even scored across. We had to tape these up ourselves so the hot air was not flowing out into the roof space but towards the rooms in the actual house. The unit itself had also not been taped up on one side, so again a lot of hot air was escaping from that part.

We went with a HVAC installer who used subcontractors to do each part of the job, which we didn’t know that was how they worked and we wouldn’t recommend it. They turned out to be a service which stopped when the money was paid and provided mediocre service when the system didn’t work properly, instead of sending in the original installers to fix it properly. Telling us there was no problem, until we went into the roof ourselves and found things hadn’t been done properly.

The installers also did not install drain pipes in the outdoor condenser to direct the water away from our house. They also did not install the condenser on feet to raise it so we could add the drains in ourselves, when we found this issue and saw that the condenser will produce a lot of water during heat mode. The manufacturer advise that it is not a requirement, but a recommendation to install the drains and to install on feet, so we are left with a problem that will damage our house structure over time. So make sure you instruct your installer to install the drain pipes and direct it into a drain or at least away from the house.

The huge twin condenser fans of a 16kwh unit are scary when they are blowing outside and you can feel the draw from the fans.
