Heat Pump Ratings part 9: Reviews of DiamondAir, Ducane, Ecologix, & Everrest Elite Series

BRAND--------BASIC-PREMIUM-ULTIMATE

DiamondAir------<1*-------<1*---------NA

This brand is manufactured for sale on the internet. They offer basic heat pumps with a 13 seer efficiency and durable scroll compressors as well as a premium model. The warranty is not very good but they are inexpensive.

DUCANE-------<1*---------<1*---------NA

This brand is from ALLIED AIR ENTERPRISES INC which is owned by LENNOX INTERNATIONAL. The 4HP13B models are basic units with all of the standard features but the warranty is not very good and they have a wire guard to protect the condenser coil which does not actually provide much protection. The 4HP16LT models are premium units with an efficiency of 16 seer and a heavy duty compressor blanket for enhanced noise control. They have a swept wing fan for sound control and use quietshift technology for quieter operation when entering and exiting the defrost mode. The units are only sold through authorized dealers and the warranty is not very good when compared to other brands.

ECOLOGIX------<1*---------NA---------NA

This brand is made and sold in Canada. The units are designed for cold climates and have digital communicating controls. The variable speed compressor is located on the inside of the home which is different and could cause noise issues but it is inside of a well insulated cabinet. Their website is not much help and does not have a stated guarantee for their products.

EVERREST ELITE SERIES--1*--5*------5*

These units are made by GOODMAN MANUFACTURING which is a part of DAIKIN GLOBAL. The ASZ14 models are basic 15 seer heat pumps with an average warranty. They have louvered metal panels to protect the outdoor coil and use smartshift technology for quieter operation. 

The ASZC16 series offers premium heat pumps with the ability to communicate with the rest of the home's HVAC systems. They also have a two speed condenser fan for quieter operation and are backed by a very good warranty. The AVZC20 units are their entry in the ultimate class. They have a variable speed condenser fan motor as well as compressor for very efficient and quiet operation. They are backed by an industry leading guarantee but are only available through authorized dealers.
