Paul requested 3 quotes from Air Conditioning Professionals in Montmorency
Daikin oudoor unit RXD80CV4 has a possible error code E7 according to diagnostic test.
Indoor unit's light remains on, but unit does not operate. Power cycling at mains can result in the internal unit running, but no cooling, just fan.
May consider preventative servicing of other three units depending on quote.
