Gas Furnace Ontario: What is the average cost for a new furnace in Ontario?

Furnaces are fundamental to the cold climes of Ontario. And while the sheer comfort of a warm home on a chilly day feels priceless, the tangible cost of installing a new furnace can vary widely. On average, the cost for a new gas furnace in Ontario ranges between $3,000 to $5,000. However, this price can fluctuate based on the furnace brand, efficiency, installation complexity, and additional features.

Remember, though the initial outlay might seem high, a well-chosen furnace will eventually pay for itself in energy savings and prolonged lifespan. It’s essential to view this as a long-term investment, especially if you plan on staying in your home for years to come.

Is it legal to install your own furnace in Ontario?

Navigating the maze of legalities can be as tricky as finding a needle in a haystack. In Ontario, the law stipulates that only licensed technicians can install gas furnaces. This is due to the potential dangers associated with incorrect installation, which can lead to gas leaks, fires, and other safety hazards. If you’re a hands-on person, this might sound like a rain on your parade. But trust me, sometimes it’s better to let the pros handle it.

Furthermore, any DIY attempts can jeopardize your manufacturer’s warranty and may not meet the stringent safety standards required by insurance companies. It’s a no-brainer; the safety and well-being of your family should always be the top priority.

How many years should a gas furnace last?

The lifespan of a gas furnace can often remind us of our own fleeting youth. On average, a gas furnace should last between 15 to 20 years. But here’s the twist – just like humans, furnaces too can age gracefully with a bit of care. Regular maintenance, annual check-ups, and prompt repairs can extend its lifespan, ensuring you get the most bang for your buck.

What size furnace do I need for a 2000 square foot home?

Ah, the age-old question of size. The furnace size you’d need for a 2000 square foot home largely depends on various factors, including the home’s insulation, number of windows, and overall architectural design. Typically, a rule of thumb is 30 to 60 BTUs per square foot for moderate climates. Therefore, a home of this size would generally require a furnace with a capacity of 60,000 to 120,000 BTUs.

However, always consult with a heating specialist. An oversized furnace can increase your energy bills, while an undersized one might not provide adequate warmth. It’s like Goldilocks; you want the size that’s just right.

How many BTUs should a furnace be for a 1500 square foot house? And How big of a furnace do I need for a 1500 sq ft house?

Bundling these two together, for a 1500 square foot house in moderate climates, you’d typically look at a furnace ranging from 45,000 to 90,000 BTUs. Again, remember the Goldilocks principle. Your home’s specific needs might be different, so always consult with an expert before making any decisions.

Do you include the basement when sizing a furnace?

To include or not to include, that’s the burning question. When sizing a furnace, it’s generally recommended to include the basement if it’s a living space or if you plan on using it regularly. A cold basement can affect the overall comfort of your home. It can also lead to issues like frozen pipes in the winter. Better safe than sorry!

Is a higher BTU furnace better?

More doesn’t always mean better. While higher BTU furnaces provide more heat, they may not be the best fit for smaller homes. An oversized furnace can cycle on and off frequently, leading to increased wear and tear and higher energy bills.

What happens if a furnace is oversized?

An oversized furnace might sound like a good idea, but it’s a slippery slope. Apart from cycling on and off frequently, it can also produce inconsistent temperatures, lead to premature breakdowns, and increase your energy bills. Remember, size matters!

Is it better to oversize or undersize a furnace?

Neither, actually. An oversized furnace can lead to higher energy bills, while an undersized one might not heat your home adequately. It’s always best to get the right size for optimal performance and efficiency.

What is one disadvantage of oversizing a furnace?

One major disadvantage is the rapid wear and tear due to frequent cycling. This can lead to frequent repairs and a shorter lifespan.

Is a single stage or two stage furnace better?

A million-dollar question, indeed! Single-stage furnaces are more affordable and have a simpler design. They’re either on or off. On the other hand, two-stage furnaces offer more flexibility as they can operate at a low or high setting based on the heating demand. This ensures better energy efficiency and consistent temperatures. For those willing to invest a bit more upfront, a two-stage furnace often pays off in the long run.
