A/C HVAC advice ?

[waheri3]

We plan to replace our 3 ton A/C unit with a heat pump designed to work in conjunction with our oil burning furnace. The heat pump will be the principal heat source until the outside temperature drops to 30 degrees or so, at which point the oil burner will take over.

We’ve received several estimates from HVAC companies, including American Air Systems and Gunstock HVAC. American Air Systems proposes a Bosch heat pump (model # BOVA 36HDN1-M18M) and Gunstock has proposed a Samsung unit (model SAMCCXH36UPB).

Would appreciate feedback from anyone who has received services (including new installations) from either American Air Systems or Gunstock HVAC. Also, would like feedback from folks who have experience with either of the Bosch or Samsung units described above.
