What’s the Best Type of Furnace to Install?
It’s a question that you never typically envision yourself asking, as you scroll through countless articles on Google. Should you go for the ritzy modulating furnace, or should you stick with the bare-bones single stage? Ultimately, the decision will completely depend on your application, as well as your budget.
To help you with this decision, we’ve broken down the different types of furnaces currently available on the market, so you can feel better informed when going through your next furnace replacement.
Single Stage Furnace
A single stage furnace will heat your home with one heating temperature and blower speed. This means the temperature in your home will jump up and down continuously, as they run on short heating cycles, waiting for the home to dip below a certain temperature before kicking back in again. Single stage furnaces are considered a basic furnace, and will be the most affordable option to heat your home.
2 Stage Furnace
When you start to heat your home, a 2 stage furnace will come on at 60% of its heating capacity for the first 10 or so minutes. When you need higher heat output to bring the house up to temperature quickly, the second heating stage will kick in and run at 100% capacity. The longer, slower heating cycle eliminates the rapid warming that many people find uncomfortable from single stage furnaces. The 2 stage furnace is considerably quieter, and generates more even heat throughout your home.
This is the unit we recommend for most households, as it provides a perfect balance of increased home comfort, high efficiency operation, low noise levels, and long term value.
A modulating furnace is the most expensive type of furnace, as it has complicated electronic components embedded in it. It runs in very precise increments when heating your home: it starts at 40% heat capacity and increasing by 1% as needed to heat your home. This makes the modulating furnace an ideal unit for homes with zoning applications.
We do not typically recommend this furnace for most homes, as it is no more efficient, nor does it provide a high level of home comfort than a 2 stage, variable speed furnace.
There are many factors to consider when making this important investment that could last you upwards of 20 years. If you’re installing a furnace in your ‘forever home’, you might want to spend a bit more money on a modulating or 2-stage furnace.
