Pay heed to the 1 star reviews, a case of buyer beware. When you book a service, they quote a $79 call out fee which is covered if the service is taken. They never mentioned upfront (when you book) a further diagnosis fee of $200+ before they even quote. Granted the technician is clear on the diagnosis cost when onsite (nice surprise for customers)...but what does one do when service shows up and ask for more money just to look at the problem? Send him/her away and throw away the $79 call-out? Again diagnosis cost was said to be covered if service is accepted.
In my case, it was diagnosed that the hotwater system failed because the off peak power meter was faulty (which energy aust fixed the next day). The Omega diagnosis took 2-3 minutes and you add up the the call-out and diagnosis fees. Since no service can be provided by Omega, it was a very costly all-out. Granted in some other cases, the diagnosis could take a lot longer and Omega can provide service. No issue with the 3 min mine took. My point is you need to understand how Omega charging works before you engage. Also treat the advertised discount for not being on time as marketing gimmick. My technician was 45 minutes after service window. The HWS was installed by Omega originally (previous homeowner and that's how I got to them). The HWS has a sticker for 15% discount off future services. I never mention the lateness and the discount because I always want to test how a business operate. In this case, I suspect what they will get away with, Omega will. When I rang up to enquire about Omega's charging method, the lady on the phone said her job is only to schedule work and can't help with bills, so I paid a visit to Omega's premise today. So I did confirm these matters in person before committing to this feedback. You judge for yourself whether to use Omega Services or not.
