Air conditioner ratings part 7 continues our expert and unbiased reviews with a look at the Comfortstar, Concord, and Daikin brands.
The ADA2 models are a part of their QUANTUM SERIES and have an efficiency of 14 seer. They have a durable scroll compressor and fully louvered metal jacket to protect the condenser coil from physical damage. Their website is not much help and the warranty on the brand is not very good when compared to others.
This brand is from ALLIED AIR ENTERPRISES which is a part of LENNOX INTERNATIONAL. The units are available in the USA through dealers but it is a somewhat limited network. The 4AC14L models are basic units with all of the standard technology while the 4AC18LT models are premium units.
The 4AC18LT units have sound blankets on the compressors and variable speed condenser fan motors with swept wing fans for very quiet operation. They have Copeland UltraTech compressors with advanced onboard diagnostics to make diagnosing problems easier. All of the units have slotted panels to protect the condenser coil but the warranty on the compressor which is the heart of the unit is not as good as other brands.
The DX13SN is a basic air conditioner with louvered panels to protect the coil as well as a compressor sound blanket to minimize the noise during operation and an ECM condenser fan motor for long lasting energy efficiency. They are backed by an industry leading guarantee in the basic category. The DX18TC is a premium unit with a compressor sound blanket for noise control and a two speed ECM condenser fan for added energy savings. The unit has the ability to communicate with the other parts of the home's HVAC systems to maximize comfort and efficiency.
The DX20VC is an ultimate unit with variable speed compressor technology and a 24.5 SEER rating. They are very quiet when running (less noise than a normal conversation) and the DAIKIN INSIDE onboard diagnostics monitor operation for efficiency and reliability. The brand is backed by a very good warranty but the units are only sold through their authorized dealer network.
