Furnace Services FAQs

Why does my furnace smell like it's burning?

When you run the furnace for the first time, a burning smell is usually due to dust that is burning off. If it smells like it’s burning at other times of the year, you might need professional furnace repair.

What's the best furnace size for my home?

Every home is different, so your furnace size will depend on the size of your home and your budget. The team at Black Diamond can evaluate your needs and recommend the best options for you.

How often do I need to change my furnace filter?

This depends on your filter type. If you have a 1-inch filter, this should be changed monthly, but a media filter can last up to six months, depending on conditions in the home.
