My Mitsubishi Air-Con was installed earlier this year and I was told it would need a service same time next year. However, it leaked after 6 months and I had to call them in. They are now suggesting this unit is serviced 3 times/year which is very costly for me. I asked advice from another company whom I told this unit was in constant use but they still said they would only service it twice/year and that perhaps my installer were 'trying it on' - their words not mine. They went on to say that only in environments such as restaurants and hair salons would a unit require more service checks.

What does anyone else think? I am really stuck now and don't know what to do.
