HVAC Services We Provide in Eagle

We handle the full range of heating and air conditioning work for Eagle residents and businesses: repairs, new system installations, equipment upgrades, design-build projects, and sheet metal fabrication. We install Lennox systems and service all major brands, including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant. Whatever equipment is in your home or building, our technicians can work on it.

We start every service call with a thorough inspection before making any recommendation. Our approach to repair-vs-replace guidance is straightforward: we don’t suggest more than your system actually requires. When a system is aging and repair costs are stacking up, we can tell you when replacement may make more financial sense.

Signs your heating or cooling system may need attention:

  • No warm air coming from the furnace
  • No cold air from the air conditioner
  • Unusual rattling or pinging sounds during operation
  • A discolored pilot light
  • A furnace that cycles on and off too frequently
  • A sudden, unexplained rise in energy bills

If your system is showing any of these signs, don’t wait for a full breakdown. Catching problems early can mean a lower repair cost and a shorter service window.

Annual Maintenance Agreement

We recommend one spring check-up for your air conditioning system and one fall check-up for your heating system each year. Staying ahead of seasonal demand can help prevent breakdowns, improve efficiency, and extend the life of your equipment.

Our Annual Maintenance Agreement makes that easy. Members receive a furnace check-up and an air conditioner check-up, priority scheduling, no overtime charges for after-hours calls, a detailed 30-point inspection, and a 10% discount on all parts and labor when repairs are needed. It’s a straightforward way to help protect your investment and help you avoid the cost and stress of an emergency call in the middle of a Wisconsin winter. We also offer 24/7 emergency service for heating and cooling calls, with competitive pricing and flexible scheduling to fit your situation.

What Sets H.J. Faust, Inc. Apart from Other HVAC Contractors

We develop our technicians through our structured Internal Apprenticeship & Development Program, which combines structured classroom instruction with direct field experience under Senior Mechanic supervision. On top of that foundation, every field and office employee attends at least four additional training sessions per year to stay current on new equipment, technologies, and processes.

We’re also a company with deep roots in this region. Each year we participate in the Lennox Feel the Love program, nominating a deserving household and donating and installing a new heating or cooling system at no cost to that family. We sponsor the Tall Tales Music Festival, the Burlington Turkey Trot benefiting Love, Inc., and the Transitional Living Center of Burlington, and we support local athletic programs, schools, and the Chamber of Commerce. On every job, our crew recycles all eligible material and disposes of the rest responsibly. These aren’t add-ons. They’re part of how we’ve operated as a privately held company for more than four decades.
