The Ameristar team is pleased to announce that the M4HP4 heat pump has been improved to deliver increased performance ratings and more air handler matches. The 9th digit of B or A will be advanced to C or B, respectfully, to reflect the change.
Old models will be phased out and sold prior to the new models being phased in and sold. There will be no price change from the previous model to the new model.
New models will not be available for order until current inventory is depleted (first order date is as we deplete inventory of the old model). Updated technical specifications are available for download on the Ameristar website, including changes in electrical properties and dimensions.
