Maintaining Your High Efficiency Furnace

Once furnaces reach 90{1c74626021d9c5a8d5059ea98d64b8f290317673ada7d772ef8a992974ff6973} AFUE or better, venting and combustion processes change considerably. High efficiency furnaces are direct-vent appliances, which means that both exhaust and intake air (combustion air) are piped directly to the outside. No indoor combustion air is utilized. The combustion chambers are sealed for better control of the combustion process.

Any gas fired appliance must have combustion air. On residential homes with open basements the intake air on some models draws its combustion air from inside the home. Some models require a separate combustion air intake vent from exterior air source.

Venting you high efficiency furnace can be straight forward or complicated. You must do the math. The installation manual will have a venting chart, which gives maximum lengths for each size of piping allowable. Depending upon the length of run, the BTU output of the furnace, and the amount of elbows needed, will determine the pipe size required for proper venting. Newer furnaces now require vent pipe to meet the CSA 636 pipe standard which is easy identified as being white PVC pipe with correct markings.

The condensate developed by the furnace is required to be disposed of. You can use plastic and some metal drains or you can use a condensate pump to pump directly into on of your drain lines.

Keep in mind that regular and proper maintenance of your furnace is relatively inexpensive, will extend the life of your heating system, save you energy ollars, and ensure your homes comfort and safety. Make sure your home heating system is working at peak efficiency.

While Canada’s EnerGuide label helps you to compare how much energy a product uses, the ENERGY STAR symbol helps you to identify which ones are the most energy-efficient. When shopping, look for the EnerGuide Label along with the ENERGY STAR symbol.

Using a programmable thermostat, you can adjust the times you turn on the heating or air-conditioning according to a pre-set schedule. Programmable thermostats can store and repeat multiple daily settings (six or more temperature settings a day) that you can manually override without affecting the rest of the daily or weekly program.

Professional home inspector’s will run your furnace and check all registers and cold air returns to ensure proper operation. The home inspector will also remove covers and inspect for leaks, rust and condition of filter.
