  • Heating bills are higher than normal

Discover the Comfort Benefits of Boiler Installation

A boiler (also known as a hydronic heating system) is a popular choice for many Pewaukee homeowners and business owners because of the even, comfortable heat it provides. Choosing a boiler comes with the following benefits:

  • Steady, even heat dispersed more efficiently throughout rooms
  • Fewer allergens and less dust in the air because there are no blowers or fans
  • Energy savings when combined with user-friendly zoning and programmable thermostats

Our experts can also suggest in-floor radiant heating. This option provides consistent, even heating concentrated at the bottom third of your home where it can help you feel most comfortable.

Our pros can also recommend customization options, including zoning and ductless systems. And if you need a repair or full replacement down the road, you can trust us to handle that with care, too. In either case, we make installation seamless and provide follow-up maintenance service to keep you comfortable for years to come. Working with Interstate is your guarantee for the best service.
