Boilers Are a Great Heating Option for Delafield Homes

Boilers are popular heating systems among Delafield homeowners, with significant benefits compared to traditional furnace heat:

  • More efficient than a forced-air system
  • Option of pairing with in-floor radiant heating
  • Quiet operation
  • Improved air quality
  • Less drying than hot air units

If you’re curious if a boiler is right for your home, let’s talk. Not every comfort provider performs boiler installations and repairs, but these are some of our specialties.

Delafield Residents Trust Us to Service Their Furnaces

When it comes to staying warm during cold Wisconsin winters, Delafield homeowners know there’s only one company to turn to—Interstate. From furnaces to heat pumps, there’s nothing our pros can’t handle. We expertly install all types of units, and deliver follow-up maintenance and repair services down the road as needed. We can even help with options like zoning or ductless split systems for rooms that are hard to keep warm. No matter what system or brand you choose, we’ll tailor each installation to your unique comfort needs and budget.

We Expertly Install Air Conditioners, Ductless Systems, and More

Summers in Delafield can get pretty hot. This is when air conditioners run almost nonstop and experience frequent breakdowns. We prioritize repairs to get your system up and running safely. But if your system is past its lifespan, or the cost of a repair is more expensive than its worth, our professional technicians will recommend an air conditioner replacement. They have the knowledge to:

  • Evaluate your home’s size
  • Assess the layout and functionality
  • Suggest a unit with ideal capacity—able to keep up with your needs without overcooling and wasting energy

A properly sized system keeps you comfortable and ensures maximum efficiency, and can last up to 20 years with annual maintenance.

Your Indoor Air Quality Is Our Priority

Indoor air quality (IAQ) plays an important role in your comfort—when the air all around you is free of dust, pollen, pet dander, bacteria, and other impurities, you’ll notice the difference. You’ll also feel better when humidity is balanced—too much and your home can be musty and muggy; too little and you’ll feel itchy and achy. Our Delafield customers know they can leave this often forgotten aspect of comfort to us. We recommend and install:

  • Humidifiers
  • Dehumidifiers
  • Air purifiers
  • UV lights
  • Ventilators
  • Air filters

Not sure what products you need, if any? No problem. Our experts can assess your indoor air quality and make recommendations to ensure the air in your home is clean and healthy.
