Should I Get a Single-Stage, Two-Stage, or Modulating Furnace?

When it comes to furnaces, there are multiple options to choose from: single-stage, two-stage, and modulating. So how do you know which one is best for your home? Below, we'll explore the differences between these three types of furnaces and help you decide which one is right for you.

What is a single-stage furnace, two-stage furnace, and modulating furnace, and how do they work?

Most furnaces in homes are single-stage. That means the furnace has one speed: when it's on, it's running at full power. A two-stage furnace has two speeds. It runs at low power most of the time, but when the temperature in your home drops, it kicks into high gear to warm things up quickly.

A modulating furnace is like a two-stage furnace on steroids. Not only does it have two speeds, but it can run at varying speeds between low and high. That means it can constantly adjust its output to match your home's heating needs.

As a result, modulating furnaces are much more efficient than their single- and two-stage counterparts. They also tend to be much quieter because they're not constantly cycling on and off.

Should I buy a single-stage, two-stage, or modulating furnace? What are the pros and cons?

When considering which furnace to buy, you’ll want to look at factors like installation price, energy efficiency, and operating costs.

  • Single-stage furnaces are the most basic and affordable option. However, they can produce higher energy bills because they operate only at full power when turned on.
  • Two-stage furnaces are more expensive, but they're more efficient because they have low and high settings. This allows them to run at a lower setting most of the time, which saves you money on your energy bill.
  • Modulating furnaces are usually the most expensive option, but they’re also the most efficient due to their variable-speed motor. They can also provide the evenest heating throughout a home, which is useful for heating large, multi-story houses.

If you need help deciding which type of furnace to buy, it depends on your budget, needs, and situation. If you want the most bang for your buck long-term and the most control over your home’s temperature, go with a modulating furnace. But a single-stage furnace will do the job just fine if you're on a tight budget or know you’ll be moving to another home soon.

Are there any other factors I should consider when choosing a new furnace for my home besides price and performance?

Along with price and performance, there are a few other things you may want to consider if you’re in the market for a new furnace. For example, the size of your furnace is critical– you don't want to end up with one that's too small or too large for your home. Improper sizing leads to performance and efficiency issues. (In other words, don’t buy a smaller furnace thinking it will save you money.)

You'll also want to think about the fuel type. If you're looking for something with a lot of heating power, gas furnaces are typically the way to go. However, if you're concerned about the environmental impact of your choices, electric furnaces may be a better option, as they do not emit any pollutants. Whatever your priorities, doing a little research beforehand will help you find the perfect furnace for your home.

Should I replace my old furnace with a new one or just repair it if it's broken?

As your furnace ages, it becomes less efficient and more expensive to operate. At some point, you'll have to decide whether to replace it with a new one or just repair it once again if it's broken.

To help you make that decision, here are a few things to consider:

  • First, take a look at the age of your furnace. If it's 15 to 20 years old, it's probably time for a replacement. Not only are newer furnaces more energy-efficient, but they also emit fewer pollutants.
  • Second, consider the cost of repairs. If the cost is more than half the cost of a new furnace, it makes sense just to replace it.
  • Finally, think about your comfort level. A new furnace will provide more consistent heating, while an old one may produce a lot of hot and cold spots.

Ultimately, whether to replace or repair your furnace is up to you. Hopefully, these considerations will help you make the best decision for your home and budget.
