What Sets H.J. Faust, Inc. Apart

Not every HVAC contractor invests in training the way we do. Our mechanics enter through the Associated Builders & Contractors (ABC) Apprentice Program, a state-approved curriculum that pairs classroom instruction with hands-on field work under direct Senior Mechanic supervision. On top of that structured pipeline, every field and office employee attends a minimum of four training sessions per year to stay current on new equipment, technologies, and processes.

Our commitment to honest service is just as important. Before recommending any solution, we start with a thorough inspection, and we won’t recommend more than your system actually requires.

Our Annual Maintenance Agreement benefits include:

  • Furnace check-up and air conditioner check-up
  • Priority scheduling
  • No overtime charges for after-hours calls
  • 30-point system inspection
  • 10% discount on all parts and labor when repairs are needed

We also participate each year in the Lennox Feel the Love program, donating and installing new heating or cooling equipment at no cost for a deserving family in the community. It’s one of the ways we stay connected to the people we serve.

Heating Services for East Troy Homes

Wisconsin winters don’t leave room for a furnace that’s running on borrowed time. We handle the full range of heating work: furnace repair, preventative maintenance, and heating system installation and replacement. Our technicians are equipped to service furnaces, heat pumps, boilers, geothermal systems, and ductless mini splits, installing Lennox equipment and servicing major brands including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant.

We recommend a fall heating check-up each year before the season begins. Catching worn components, ignition issues, or airflow restrictions early can reduce the risk of a mid-winter breakdown. If something does go wrong, our 24/7 emergency service means you won’t be left without heat when temperatures drop.

Air Conditioning Services in East Troy

When Wisconsin’s humid summers arrive, a struggling AC unit isn’t just uncomfortable. It can drive up energy costs and leave your home feeling unmanageable. We offer AC tune-ups, repairs, and installation and replacement services across all major brands, with Lennox systems available for new installations.

A spring tune-up gives our technicians the opportunity to check refrigerant levels, electrical connections, and mechanical components before peak cooling season. If a problem surfaces mid-summer, our 24/7 emergency repair availability means a fast response is available.

Indoor Air Quality Solutions

Your HVAC system moves air through your home constantly, and what’s in that air matters. Standard filtration catches a lot, but dust, pollen, and other airborne contaminants often require more targeted solutions. We install high-efficiency air purifiers and filters designed to address what basic filters miss.

Humidity control is equally important. Too little moisture during winter months can cause discomfort, while excess humidity in summer can create conditions that promote mold growth. We offer humidifiers, dehumidifiers, and ventilation systems solutions to help maintain a balanced indoor environment year-round.

Commercial HVAC for East Troy Businesses

Commercial HVAC systems carry different demands than residential ones: greater load requirements, multi-zone configurations, and operational continuity that can’t afford long delays. H.J. Faust, Inc. delivers end-to-end commercial solutions, including design-build projects, new construction, systems upgrades, and sheet metal fabrication. We don’t hand off partial work. We manage the full scope.

Our 24/7 emergency response covers commercial accounts as well. Whether you’re managing a retail space, office, or industrial facility, an unexpected HVAC failure doesn’t have to mean extended downtime.
