Had the Omega Climate Systems ducted heating unit installed just over three years ago. Selling point at the time was that it comes with ten year warranty.
Just recently it decided to start playing up and it was strange since heating wasn't used for some time (since it's summer time) but the unit just started humming loudly (some fan) but there was no air flow in the house. I guess it was some kind of internal cooling.

Called Omega and arranged someone to come out and take a look.
Repairman showed up a day or two later. He went straight for the only control board in there (felt like he already knew exactly what the problem was even before taking a look and it was something he gets to do a lot :P)
Quickly replaced the flimsy looking thing and charged $410 for it. Add $170 call out fee on top of that.

Then it turns out that those ducted heating units have only three year warranty (I don't replace these things that often so I don't know what a standard would be but that just seems weak) and conditional 10 year warranty (that calls for regular servicing and so on).

After the repairman left I did a bit of snooping around and found the same control board for about $250 and one place that charges only $120 if you send them the damaged part since they try to recycle those things.

Sent an email to the company with these details and never got a reply.

So, four months out of three year warranty a part burns out for no reason and you get charged hundreds of dollars for the same flimsy part and few minutes of work.

I just feel ripped off and stuck with substandard heating unit. Stay away from this stuff...
