These heat pumps are made by Nordyne for R.E. MICHEL COMPANY which is a distributor of HVAC systems in the USA. The VT4BE is a basic heat pump with a durable scroll compressor and a composite base pan for quieter operation. The VT4BF is a premium unit with a Copeland Ultratech scroll compressor. The unit uses demand defrost for added energy savings over a timed defrost but the warranty is not as good as many brands. All of the units feature all metal louvered panel construction for protection of the condenser coil from mechanical damage. They also offer R-22 replacement units that are shipped without refrigerant as R-22 is being phased out. The units are only sold through their authorized dealer network.
