As title says, we installed mini splits almost 3 years ago, and about mid February they started giving FO error. We didn't seek help right away as we also have an oil tank, but we now require help!

Homeworks came to check on them, and the lowest estimate for checking it for leaks alone is about 2k, if additional fixing is needed is another 3k.

I'm not knowledgeable on the matter, but the cost seems a tad excessive, so I was wondering if anyone has any HVAC maintenance leads to ask for a second opinion.
