The simplest method for remembering the distinction between these two types of heating systems is that a furnace utilizes air to disperse heat all throughout your home, whereas a boiler uses water. A furnace warms the air, which is then spread all across the residence by a blower motor and a duct system that connects to each room using vents. On the other hand, a boiler unit will heat up water to generate steam. This steam is then pushed throughout your home using your duct system, which, again, connects to every room via air vents.

Yes, your home’s boiler unit is responsible for heating your home and the water that runs through your water line. As such, it combines the functions of a water heater and a heating system, making it ideal for homeowners who want to decrease their carbon footprint and maximize their energy costs.

All homes are different. Therefore, before determining which boiler is best for your home, you will need to book a consultation appointment with the professional and certified HVAC team at Dunn Heating. During this appointment, a technician will come to your home and conduct an inspection before providing you with a recommendation as to which system is ideal for your needs. At the same time, they will also provide you with an installation quote.

What Homeowners Say About Dunn Heating HVAC Services

“After a weekend away we arrived home Sunday night with no AC. I called Dunn first thing Monday morning and had a technician here within the hour! He explained that the unit could either be repaired or replaced and gave us a quote. We decided to replace the unit and that same morning they had a crew here installing it! The installers were friendly, neat, professional and skilled.
Very happy with Dunn and would recommend.

“In December my furnace started acting up and wouldn’t stay on. I called Dunn Heating that morning and they sent a technician to my house within an hour. Gary had the furnace up and running in no time, and it’s been running great ever since. I have told all my friends about Dunn Heating’s fast and courteous service. I am going to sign up for the yearly maintenance program too. Thanks Dunn Heating!
