We Deliver Timely Furnace Repair Service When You Need It Most

The NATE-certified technicians at Interstate know how important a working furnace is during brutal Wisconsin winters. That’s why our team stays up to date on furnace repair and maintenance best practices—and we’re also available to answer common questions or offer sound advice.

First, we teach you the top warning signs that your furnace needs attention—these include:

  • A furnace that emits excessive dust, soot, or dirt particles
  • Monthly heating bills that are rising
  • A system that’s louder than usual
  • A unit that constantly cycles on and off
  • Uneven heat throughout your home

If it’s time to install a new furnace, rest assured we are one of Wisconsin’s largest Carrier® dealers and have plenty of energy-efficient system options that are built to last.

Boiler Installation and Repair Service—We Do It All for Waukesha

Though they’re not the most common heating source, boilers (also referred to as hydronic heating systems) are still a popular option for Waukesha home and business owners. These systems are renowned for even, consistent heat and energy efficiency. Top benefits of a boiler include:

  • Steady heat dispersed evenly and efficiently throughout rooms
  • Fewer airborne dust or allergens because air isn’t being blown around
  • An ideal pairing for in-floor radiant heating systems
  • Energy savings when combined with user-friendly zoning and programmable thermostats

Our experts can also recommend ways to customize your home’s comfort system with zoning and ductless options. And if your cooling system needs a repair or replacement installed, the skillfully trained pros at Interstate will accurately diagnose the issue and guide you to the best solution.

Enhance Your Air Quality With a Humidifier or Air Purifier Installation

Indoor air quality is an often overlooked aspect of home comfort—but our Waukesha-area customers know it’s one of our priorities. From in-home air purifiers and ultraviolet lights that prevent contaminants from recirculating through your home’s air to humidifiers and dehumidifiers that keep your home’s air at an ideal moisture level, Interstate provides a variety of options to fit your home’s size, concerns, and budget.
