Your heating bill this winter was set, in part, by decisions made in Moscow, Riyadh, and Tehran. If you heat with oil or propane, you probably already know this. Every time there's a war, a blockade, or a production cut halfway around the world, the price at the delivery truck goes up. Keith and the team at ECM have been working through this with Kingston-area homeowners for years. The pattern is consistent, and it's not random. Here's what's driving it, and what you can actually do about it.

Geothermal heating doesn't burn fuel. It moves heat. Specifically, it pulls heat from the ground beneath your property. This heat, sits at a stable 8 to 10 degrees Celsius year-round in this region, even when it's minus 25 outside, and transfers that heat into your home.

Depending on how long you plan to stay in your home, that $69 a month could end up costing you three to four times the price of simply buying a furnace outright.

It's mid-February in Eastern Ontario, and if your furnace has been running hard since November, now's the time to check in on it. We've been fielding a lot of heating calls lately, and most of them come down to one thing: homeowners didn't notice the early warning signs until the system failed. Here's what to listen to and watch for.

Look at the edge of the filter frame. You'll see three numbers printed there, something like "16x25x1" or "20x25x4". These represent:

• First number: Width

• Second number: Height

• Third number: Thickness

Write these numbers down. This is your furnace filter size chart starting point. Don't buy yet.

Modern HVAC technology has changed dramatically over the past decade. The systems being installed today operate in ways that would seem like science fiction compared to the furnace your parents had. And the efficiency gains aren't minor adjustments—they're the kind of improvements that genuinely reshape your wallet and your comfort through a Belleville winter. Let’s walk through what's actually changed, why it matters for your home, and how to know if an upgrade makes sense for your situation.
