Boiler vs furnace: Which system is right for you?

Understanding the Pros and Cons of Boilers and Furnaces

If you’re considering a new heating system or replacing an old one, you’ve probably come across two main options: boilers and furnaces. Both systems can keep your home warm during Michigan’s long winters—but they work in very different ways.

At Home Run Mechanical, we help homeowners in Ann Arbor and surrounding areas choose the system that best fits their home, lifestyle, and budget. Here's a breakdown of how boilers and furnaces compare—so you can make a confident, informed decision.

What’s the Difference?

Boilers: Boilers heat water, not air. That hot water is circulated through pipes to radiators, baseboards, or radiant floor systems to warm your home.

Furnaces: Furnaces heat air and push it through your home using ductwork and vents. It’s the most common type of heating system in the U.S., especially in homes with central air conditioning.

Pros and Cons of Each System

✅ Boiler Benefits

• Provides quiet, consistent heat without blowing air

• Great for zoned heating and individual room control

• Doesn’t circulate dust or allergens—great for indoor air quality

• Pairs well with radiant floor heat

❌ Boiler Considerations

• Slower to heat up than a furnace

• Higher upfront installation costs

• Not ideal for homes without existing radiant piping

✅ Furnace Benefits

• Heats quickly and warms the entire home fast

• Lower installation costs (especially in homes with ductwork)

• Compatible with central air conditioning

• Easy to upgrade with modern smart thermostats

❌ Furnace Considerations

• Can create dry air in winter

• May cause hot and cold spots depending on duct layout

• Blows dust and allergens around if filters aren’t maintained

Which Heating System is Best for Your Home?

There’s no one-size-fits-all answer—but here’s how to think about it:

Choose a boiler if:

• You want quiet, even heat with no drafts

• You have (or want) radiant floor heating

• You or your family have allergies or sensitivities to dust

• Your home is already equipped for hydronic heat

Choose a furnace if:

• You want quick, whole-home heating

• You already have central air and ductwork

• You’re looking for a more affordable upfront cost

• You want to easily integrate with a smart thermostat or humidifier
