MIAMI HEAT PUMP-----------5*---------NA

These heat pumps are available in North and South America. The HPX series units are basic forced air units with a stainless steel cabinet and cupro-nickel heat exchangers for durability. They have stainless steel insulated drain pans to eliminate leaks from corrosion and sweating and offer many options including a desuperheater for domestic hot water production. The warranty on this brand is very good and they have an online store where they can be purchased by consumers which results in a huge cost savings. 


This brand offers basic units that have standard MERV 13 filters for improved air quality and oversized heat exchangers for added efficiency. They offer optional two stage compressors, variable speed blowers and desuperheaters for domestic hot water. The units are only sold through dealers in the USA and Canada but it is a limited network.

The R SERIES models are water to air units that feature two stage scroll compressors and a variable speed fan for added comfort and efficiency.
