Tips 5 things to know about your furnace

Published on November 4th, 2014 | by Staff


Five things you should know about your furnace

1. It could kill you.

Well, just like any other fuel-burning appliance, a furnace brings risk of carbon monoxide poisoning. Carbon monoxide is an odorless, tasteless gas that can be fatal to humans and pets. That’s why it’s important to install carbon monoxide detectors to alert you if it is detected in your home.

2. A clean air filter is critical to its efficient performance.

A furnace’s air filter is extremely important to the proper operation of the furnace and to your home’s air quality. An air filter should be replaced every three months or as often as once per month, depending on your region and your particular home.

3. It needs breathing space.

For safety purposes, furniture, rugs and other items commonly stored near furnaces should be at least three feet (or about one meter) from the furnace.

4. It’s only as efficient heating your home as you make it.

It’s important to make sure your home is sealed properly. Use expanding foam to seal gaps and holes around your home’s exterior.

5. It’s fixable by a homeowner.

Some common furnace problems can be fixed with inexpensive replacement parts by homeowners.
