Natural Gas Furnaces - Buying Tips
If the last time you shopped for a furnace was over a
decade ago you’ll notice that furnace technologies have changed. Older
furnaces were often oversized for the home they were heating. That means
you may not want to replace your furnace to the same specifications.

- Take into account the construction of your home,
your climatic region, ductwork design, filter system and space
limitations before recommending a size of furnace
- Offer a variety of models in different price and
efficiency ranges that meet your needs.
- Give you the Annual Fuel Utilization Efficiency
(AFUE*) rating on each furnace they suggest to help you make an

delivered to your home compared to the heat lost up the chimney.
High efficiency models will deliver between 90-97% of its heat to
- Leave a written estimate that includes details
on equipment, efficiency and warranty for your closer inspection
- Help you understand the EnerGuide label on the
furnaces that are recommended
- Determine if an Energy Star furnace is right for
* AFUE ratings - The Annual Fuel
Utilization Efficiency (AFUE) rating measures the amount of fuel
converted to space heat in proportion to the amount of fuel entering the
furnace. This is commonly expressed as a percentage. Energy Star labeled
furnaces must meet or exceed 90% AFUE energy efficiency rating.
EnerGuide labels are on every natural gas furnace sold
in Canada. EnerGuide is a labeling system that is regulated by our
government. Find out more details about EnerGuide
