timmmay: I had a Daikin repaired within warranty no issues.

and i expect nothing less when it's under warranty!

Mitsubishi indicated yesterday they had something they could do for us, but wanted to clarify with management. We had our Fujitsu for 9 years before we replaced it with this, and it was working 'fine'. I can see a number of people reporting this component failing after 7-8 years, so perhaps it's a known issue.

 

Hopefully, they will come to the party in some way.

 

Fujitsu is what I have. 17 years old and going 24x7 in winter months. Still working.

I went for one of the bigger Kilo Watts ones as figured it would work less harder and last longer.

Only gripe is it’s floor unit one and when set at 18 degrees lowest setting, it heats room to 25 degrees, plus when outside temperature below 8 degrees a lot of time deicing, so just gets to 18 inside then.

7 years is on the low side of what I'd expect, but the lack of information on the condition of the PCB itself (water / dirt / insect ingress etc) would make me think that it has lasted as long as it should.

I'd also be interested to know the service history of the external unit.

I don't know why people think expensive things should last 10 years... because it's the lowest double digital number?

It's like saying that cars should last 100,000k's.

Who decided that was the mythical number?

Use case, care, price paid, installation quality, location of unit are all factors and are often discounted by the person trying to claim 'but it should have lasted longer'. Very few things are fit and forget...

You have that wrong - cars are supposed to last 100,000 miles.

"It's the putting right that counts."

Great outcome, well done.

Good on you😄 . 

I think homeowners have to make sure that they are having it serviced every year to say that they are doing the maintenance. Read the copy of warranty, service and maintenance. IMHO if there is no intervening factors like vermins or moulds, etc, then the heat pump should last as what they are expected to last, 12 to 15 years. Mine is 9 years old Mitsubishi, serviced every year. I hope it lasts for another 3-6 years.

I read the manuals for both my heat pumps. Neither said it needed to be serviced. Both said to clean the filters, that's it. Heat pump servicing can be useful to clean it out, sanitise, etc, but I'm not sure it's required. One company I got to do a service just cleaned the filters and hosed the outdoor unit, which I can do myself. Another company opened both up and gave them a decent clean, which I get done every 2 or 3 years.

I wonder if I need the ducted indoor unit cleaned. Probably. More difficult to reach it.

Servicing heat pumps is a pretty well known scam. You need to use a reputable tradesman and make sure the service is actually required. I wonder, if you use the same firm each year, whether or not you are being taken advantage of; of course your specific circumstances might be different.
