Air Conditioner Ratings part 8: Reviews of the Concord, Daikin, and Day & Night brands



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 a 16 SEER efficiency that meets all of the latest regional standards. They 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 and 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. 

Daikin DX13SN

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. 

DAY & NIGHT---1*-----3*---------3*

This is one of the brands from INTERNATIONAL COMFORT PRODUCTS which is a part of UNITED TECHNOLOGIES CORP.

The PERFORMANCE 14 (N4A5) units are basic air conditioners that are suitable for all areas of the USA to meet the regional efficiency standards. They have a durable baked on finish but use a wire grille to protect the condenser coil which does not actually do much to protect it. The units are relatively loud during operation and their guarantee is not as good as some of the other brands.

The CONSTANT COMFORT DELUXE 19 (CCA9) is a premium unit with a variable speed fan motor for quieter and more efficient operation. The units have the ability to communicate with the other parts of the home's HVAC system to maximize comfort and efficiency. The CVA9 models are ultimate air conditioners with five stages of cooling operation. They are backed by a very good warranty but are only available in the USA and Canada through their dealer network.
