This brand is from ALLIED AIR ENTERPRISES INC which is owned by LENNOX INTERNATIONAL and the units are sold in the USA through a dealer network. The 4HP13B models are basic units with all of the standard features but the warranty is not very good. They have a wire guard to protect the condenser coil which doesn't actually protect it very much.
The 4HP16LT models are premium units with an efficiency of 16 seer and a heavy duty compressor blanket for enhanced noise control. The units have louvered metal panels to protect the coil which does a much better job than the wire guards. They have a swept wing fan for sound control but the warranty is not very good when compared to other brands.
All of their units feature "Quiet Shift" technology for much smoother and less noisy entry into the defrost mode.
The DZ14SN model units have efficiencies of up to 15 SEER and Smartshift technology for less noise when the unit goes into defrost.
The DZ16TC is a premium model that can communicate with the other parts of the home's HVAC systems to maximize comfort and efficiency. The unit has a high density compressor blanket for noise control and is backed by a very good guarantee.
The DZ20VC units have state of the art technology and are ultra quiet with a compressor sound blanket and ECM condenser fan motor. The heat pumps have louvered metal panels to protect the coil and are backed by a very good warranty but they are only available through their Comfort Pro dealers.

This brand is from INTERNATIONAL COMFORT PRODUCTS which is a part of UNITED TECHNOLOGIES CORP. The PERFORMANCE SERIES offers basic heat pumps in 13, 14 or 15 SEER efficiencies. The CONSTANT COMFORT DELUXE SERIES offers 16 or 19 SEER premium units but their guarantee is not as good as some of the other brands. The Constant Comfort Deluxe 18 model is their entry in the ultimate category. It has five stages of operation as well as a variable speed condenser fan motor for very quiet and efficient operation. All of their models use a wire grille to protect the condenser coil which does not do a very good job of it. The units are available in the USA and Canada but only through authorized dealers.
