If you’ve been shopping for a new furnace lately, you’ve probably noticed more people talking about variable speed models. These aren’t just another “latest feature” — they’re changing how Ottawa homes stay warm while keeping energy bills in check.
What Makes a Variable Speed Furnace Different?
Instead of running at full blast all the time like older models, a variable speed furnace adjusts its airflow to match your home’s heating needs. That means:
- Quieter operation – no more loud start-ups.
- Consistent comfort – fewer temperature swings between rooms.
- Better efficiency – only uses the power needed at the moment.
Why Is This a Big Deal in Ottawa?
Our winters aren’t just cold — they can be unpredictable. A variable speed furnace automatically responds to these changes, giving you a steady, even heat whether it’s -10°C or -30°C outside.

What About Repair Costs?
Variable speed furnaces have advanced components, but that doesn’t mean repairs are complicated for our team. If yours isn’t performing as expected, our Heating Repair & Diagnostic service is here to help.
Do They Save Money?
Yes — the real savings come from running at lower speeds most of the time, using less electricity and reducing wear on parts. Over the life of the furnace, that can mean hundreds in energy savings and fewer repair calls.
