This brand is from ALLIED AIR ENTERPRISES which is a part of LENNOX INTERNATIONAL. They offer basic units that are available in upflow, counterflow, or basement models. The "basement" models are compact units for those older basements with low ceilings. They offer 83% efficient furnaces that are backed by a very good warranty but they are only available through their dealer  network in the USA.

CROWN BOILER------1*--<1*-----------NA

This brand is distributed by VELOCITY BOILER WORKS and the oil furnaces are made by Thermo Products LLC.

They offer four different models so they will fit almost any type of installation. The units are ready to add an air conditioner and they offer an optional sidewall direct vent kit. They feature a durable efficient ceramic lined combustion chamber.

The HIBOY SHORTY unit (shown here) has a standard blower motor but a variable speed option is available for improved efficiency and comfort. The standard warranty on parts other than the heat exchanger is not very good when compared to other brands. 

DAY & NIGHT-------4*---5*-------------NA

This brand is from INTERNATIONAL COMFORT PRODUCTS (ICP) which is a part of UNITED TECHNOLOGIES CORP. The PERFORMANCE 86 OUF is a basic model that has a ceramic combustion chamber for durability and efficiency. The CONSTANT COMFORT 85 NOMV models have a variable speed blower and durable stainless steel heat exchangers. All of the models offer an optional direct vent kit and are backed by a good warranty. The brand  is available in the USA and Canada but only through their factory authorized dealer network.


This brand is from GROUP OUELLET and is sold in the USA as well as in Canada but only through their authorized contractor network. The AMP 100/200 models are multi-position furnaces with durable stainless steel combustion chambers. They offer basic or variable speed models with efficiencies of 86%. The warranty on the units (especially the heat exchanger) is not very good when compared to other brands.
