Carbon Monoxide Alarms

  • Carbon monoxide alarms sound an alarm when carbon monoxide is detected. CO is a toxic gas that cannot be seen, felt, tasted or smelled. The effects of CO poisoning can cause household members to become extremely ill or even cause death. Due to damage, poor maintenance, or defects, appliances like furnaces, ovens, fireplaces, kerosene heaters, and grills may silently emit CO. Advanced warning of CO poisoning is only possible if you install and maintain a CO detection device.

Downflow Subbases

  • A downflow subbase keeps a downflow furnace raised off of a combustible floor, which is a requirement for installation.

Equipment Supports

  • Furnace support blocks raise the equipment up to keep it away from water if the equipment is in a basement that is sometimes wet. Also, a different type of support can be used as vibration isolation dampers when installing equipment in an attic.

Furnace Hot-Surface Ignitors

  • Furnace hot surface ignitors are found on most modern furnaces to light the gas flames upon unit start-up. Electricity passes through the ignitor and makes it glow red hot. Operating under normal conditions a hot surface ignitor will last for 3 to 5 years. During that time ignitors will eventually crack and need to be replaced. Like a light bulb, they are a regular replacement item. Most ignitors are interchangeable as long as they fit in the furnace space provided.
LPT-00A LP Conversion Kit

Furnace LP Conversion Kits

  • All furnaces and boilers on our site are ready for use with natural gas. If you want to operate the furnace or boiler on Propane (LP), simply use a conversion kit here. 

Venting Accessories for High-Efficiency Furnaces

External Filter Racks

  • Every forced air heating and air conditioning system requires a filter of some kind to protect the equipment.  These filter racks connect to the return end of the furnace or air handler, and hold the filter in place.
Furnace High Altitude Adapter Kits

Furnace High Altitude Adapter Kits

  • These are high altitude kits for Goodman gas or LP furnaces.  They are typically required when the installation is above 7,000 feet or more.
