Re: Main electrical panel
Just a guess but the AC compressor is probably also the heat pump. Without knowing the draw of the individual units it's hard to say but a guess would be that you are drawing about 60 amps when all of them are on at the same time. That's not likely to cause a problem and it is just as likely that they won't all be on at the same time. If you are concerned you could update to a 200 amp panel and service or add circuits by replacing breakers with double breakers.
