$19k for 3 zone 24k BTU HyperHeat

I received a quote for a 3 zone Mitsubishi Hyper Heat system. Outdoor unit is 24k BTU, indoors are 2x 6k and 1x 9k. All in price was $19k.

Is this a reasonable price in Massachusetts?

It seems high to me since the main components seem to be about $5k-$6k and they said they would be able to complete the install in one day, but I don’t actually know anything about this.

I’m trying to get a few more quotes but the several installers I called scheduled a few weeks out just for an estimate.
