HVAC aficionados aside, most of us aren’t too concerned, or thrilled, with our furnace’s inner workings—at least until something goes wrong, when that mysterious ka-thunk in the basement could transform a perfectly relaxing evening into a one-way conversation with a blower fan.
Knowing how your system works gives you a leg up on maintenance and repair. And it may even keep you sane. Depending on how your current system fares, you may even choose to upgrade or replace your system entirely.
In this article, we’ll explore the mysterious inner workings of two popular solutions: central heating, specifically furnaces, and ductless units—the new kid on the block.
Central Heating 101: Furnaces
Although furnaces may seem intimidating on the surface, they’re actually quite simple. If you’ve ever wondered what the commotion in your basement is all about, keep reading.
Essentially, cold air is fed into furnaces and hot air blows out.
Here’s how it works:
- Starting in the furnace, the burner produces a flame that warms a heat exchanger—a block of metal pipes that retains heat.
- Next, air is blown over the heat exchanger, like a giant hairdryer, and pumped out through ductwork to the air vents.
- Waste is blown out the chimney, and return air ducts bring cold air back to the furnace to be reheated. Rinse and repeat.
And that’s what makes your home warm and toasty, folks. Since nothing in life is perfect. Here are some drawbacks to forced-air systems:
- Heat leakage from poorly sealed ducts, leading to wasted energy.
- Poor return ducts can lead to home pressurization and heat escaping outdoors.
- Air filters get clogged and gummed up.
As the new kid on the block (well, in North America, anyways), ductless heating systems are turning heads—giving bogged-down central heating a run for its money.
Deconstructing the main idea of central heat, ductless systems deliver room-by-room, or zone-based, heating for total home comfort. Typically, you can customize the temperature of any room with a wall-mounted interface, known as a “head.”
All “heads” connect to a single, outdoor air intake/compressor unit, which is easily hidden by a shrub or bush. That might not sound particularly exciting on paper, but you’ll definitely feel the difference. Ductless cooling and heating systems do it better, with a sleek, attractive unit, and programmable, remote-control capabilities.
Installing a furnace isn’t an undertaking for the faint of heart. By contrast, ductless units are surprisingly easy for your contractor to install, and they’re much more efficient than baseboard heaters.
Whether you go ductless, or opt for classic central heating, let comfort guide you. You’ll be glad you did.
