I've done a fair bit of googling to try find the answer, but haven't come up with anything definitive, and hoping someone here could shed some light on my problem ..
I had a Mitsubishi MSV-GE60 installed during winter last year - about 8 months ago, and it hasn't been right since day dot. It gets used infrequently, and the two times I went to use it during last winter (too lazy to light the fire) it failed to produce any heat at all. Turns out it had a leak, the installer was apologetic the first time, then extremely apologetic the 2nd time he had to sort/re-gas. He's spent the better part of 12 hours onsite trying to find the leak and/or repair the fault and seems genuinely apologetic that he's had to visit twice.
So I turn it on during the weeks heat-wave to cool us down, and don't get anything below 23 degrees blowing out (when set to the lowest setting of 16 degrees). It heats alright, pumping out air at 46 degrees when last checked (Unit set to highest of 31 degrees), but nothing on the cool side. Is this a sign of a low refrigerant levels? (again!).
The last two times it failed the output temperature didn't vary beyond 24 to 27 degrees on heat or cooling, but this time it seems to be 'one way'. Am I missing something simple perhaps? (filters are clean etc).
I'm thinking I need to get this replaced under warranty, since it's never been right, and also considering getting a 2nd opinion from a different Heat Pump installer .. Just thought I'd ask around myself first.
Any insight would be much appreciated ..
