Heat pump ratings part 4 continues our expert and unbiased reviews with a look at the Arcoaire, Armstrong Air, Bosch, and Brivis brands.
This brand is from INTERNATIONAL COMFORT PRODUCTS which is a part of UNITED TECHNOLOGIES CORP. The PERFORMANCE SERIES offers basic 13 and 14 SEER units with a durable baked on finish while the DURACOMFORT DELUXE 16 is a premium heat pump with sound reducing features such as a compressor blanket and quietshift technology when going into the defrost mode.
The DURACOMFORT DELUXE 18 (pictured above) is their offering in the ultimate category as the units have five stages of compressor operation as well as a variable speed fan for quiet and efficient operation. The brand only uses a wire mesh protection for the condenser coil and their guarantee is not as good as some of the other brands. The brand is only available through authorized dealers in the USA and Canada.
This brand is from ALLIED AIR ENTERPRISES INC. which is owned by LENNOX INTERNATIONAL and they are sold through dealers in the USA. The 4SHP13LB units are 13 seer units with a scroll compressor for durability and an insulated compressor for quiet operation. They also use QuietShift technology for smoother transitions in and out of the defrost mode. The 4SHP18LS models are premium units that have a two stage compressor to more closely match the load requirement of the home but their warranty in this category is not as good as others.
The 4SHP20LX (pictured above) is their entry in the ultimate category of heat pumps and it has a 20 SEER efficiency rating but the guarantee is not as good as some of the other brands. All of the units feature their MHT technology which enhances heat transfer in the outdoor unit and provides for a compact unit.
The BOVA heat pump offers state of the art technology in a compact unit. They have an electronic expansion valve for refrigerant control which allows for effective heating even down to outdoor temps of 5F. They are quiet when operating but are only backed by an average guarantee and are only sold through their contractor network.
