Carbon monoxide (CO) is continuing to be a major concern. Many of the existing properties have their original furnaces in them. These furnaces are used nine months out of the year, and most do not have routine maintenance.

Furnaces that operate dirty are prone to extensive damages. The blower motor must work harder to move air throughout the home. This is also true when furnaces have damaged and clogged filters. Routine maintenance is paramount for safe operation of any furnace or heating appliance.

CO is the byproduct of burning fuel or gas. Heat exchangers are designed to contain and move carbon monoxide up to the flue stack, where that stack will safely remove the unwanted CO into the atmosphere. The exterior of heat exchangers are designed to heat the ambient air and move that heater air into the home through the air ducts.
