RCM Furnaces

Made In USA For Over 60 Years

We visited the Allied Air Enterprises Manufacturing Facility in Orangeburg, SC. While other companies are moving out of the United States, Armstrong Air (A Lennox Company) consolidated all of their operations to one place and stayed in the United States. All the administrative, technical support, engineering, manufacturing and warehousing is done in one place. Armstrong uses state of the art equipment and processes to assemble their furnaces and air conditioners. I personally watched the entire manufacturing process from beginning to end and will stand by all of the Armstrong products indefinitely. Each Armstrong furnace is test run extensively and proven before it is ever crated and shipped to our distributors throughout Chicagoland. Armstrong has the best quality control and consistency of all the manufacturers because each furnace is run through complete test cycles.

We also maintain and service every brand.

Furnaces and Efficiency (Your Gas Bill)

Most older furnaces are called natural draft because they depend on heat to cause a draft up the chimney. These units also have pilot lights and were considered to be around 80% efficient when new. The heat exchangers in these units lose their heat transfer capabilities and efficiency falls to about 60% after 15 years of age. This is due to the design/material of the heat exchanger which begins to rust after just a few years. The simple nature of these older furnaces make them reliable so most people are reluctant to replace them. The average furnace today is about 80% efficient. This means for every dollar you spend on heating your home, 20 cents goes up your chimney in the form of unusable heat and is wasted. This is considered to be a mid-efficiency furnace. These furnaces began to appear around 1990 and are considered draft induced because there is a small blower that draws air through the furnace and then pumps it up the chimney. The heat dissipation in this design is much more stable and so it remains closer to 80% efficiency for most of its expected service life of around 15 to 20 years. In the past several years people have been becoming aware the high efficiency heating and air conditioning equipment entering the market. The high efficiency furnace is a furnace with two heat exchangers, one or more levels of heat, and multiple fan speeds. The newest are now available with variable speed fans which drastically reduce electricity consumption while reducing noise and greatly increasing comfort. The average high efficiency furnace is 90% efficient but some are as high as 95% efficiency. The result is evident in a simple comparison. Compare an old furnace to a high efficiency one. First you must understand that since a more efficient furnace does not need to be the same size as an old one because it turns more potential heat into the home instead of up the chimney. A 2300 square foot home built in 1990 came with a 150,000 BTU natural draft furnace which is around 70% efficient. (Most people in the industry will agree this is closer to 60% efficiency.) The amount of heat entering the home is about 105,000 BTU. A home this size needs 80,000 to 90,000 BTU of usable heat to properly heat it. Most homes are built with slightly larger than needed furnaces and smaller than needed air conditioners. We install a 100,000 BTU furnace that is 93% efficient and it delivers 93,000 BTU of usable heat into the home. The end result is instead of expelling 45,000 BTU of heat up your chimney, you only loose 7,000 BTU. You have just reduces your energy cost by over 33%! This is a conservative estimate.
