We Prioritize Humidifier and Air Purifier Installation in Dousman Homes

Indoor air quality (IAQ) plays a major role in how comfortable you truly feel at home. From humidity to impurity levels, even the slightest imbalance can make you to feel “off.” Next time we’re at your house to tune up your furnace or air conditioner, ask our experts to assess your IAQ. We’ll take a few measurements, let you know what we find, and then recommend a solution if you need one:

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

Have additional questions about improving and cleaning your air? Just ask! We’re always happy to share our knowledge with homeowners to help you feel more informed—after all, it’s an investment in your family’s comfort and health.

Our Furnace Repairs and Installations Keep Dousman Homes Warm

When it comes to furnaces, not all systems are created equally—nor are the furnace services that each HVAC company provides. Work with the pros at Interstate for exceptional installation, repair, and maintenance services. We have over five decades of experience under our belts and know these systems like the backs of our hands. What other heating options do we offer? We have heat pumps, which heat your home in winter and cool it in summer—and ductless systems that deliver heat directly to the rooms that need it most. And if you do a lot of projects in your garage during winter, we even have garage heaters to help you stay warm and productive in all seasons.

Curious About the Benefits of a Boiler? Wonder No More

Some homeowners pass over boilers because of the initial investment and installation process—but there are lots of reasons why you should consider one instead of a furnace. Boilers are:

  • Often more efficient than furnaces
  • More effective at providing even heat
  • Virtually silent during operation
  • Cleaner because they don’t blow dust around
  • Capable of providing in-floor radiant heating

Think a boiler might be the perfect heating system for your home? Let our pros make a recommendation that best fits your comfort needs and budget. We install these impressive systems in both new construction and home remodels.
