Honest HVAC Repair & 24/7 Emergency Service

HVAC systems rarely fail at a convenient time. In Wisconsin, the coldest nights of February and the hottest afternoons of July put maximum strain on heating and cooling equipment. That’s exactly when breakdowns happen. Our technicians are available around the clock for emergency calls, so you’re never left waiting through a temperature extreme.

Every repair starts with a thorough diagnostic. We identify the problem at the source before recommending any solution, and we don’t recommend more than your system actually requires. That approach applies to everything from minor airflow issues to complete system shutdowns. Competitive pricing and flexible scheduling make it straightforward to get the help you need without working around a narrow service window.

HVAC Installation & Replacement

A well-matched system installed correctly can perform better, can last longer, and can help support warranty coverage. Our installation process starts with a full system evaluation and load calculation to determine exactly what your home or building needs. From there, we help you select equipment, including Lennox heating and cooling systems, matched to your property size, usage patterns, and long-term goals.

Installation includes a review of duct condition and airflow capacity, removal of outdated equipment on replacement projects, and start-up testing once the new system is in place. Whether you’re installing a furnace, heat pump, boiler, or central air conditioning system, each installation is completed to manufacturer specifications. Systems more than 10 to 15 years old that struggle to maintain temperature or require repeated repairs are common candidates for replacement, and we can give you an honest assessment of where yours stands.

Annual Maintenance Agreement

The best way to help avoid an emergency repair call is consistent preventive maintenance. We recommend a spring check-up for your air conditioning system and a fall check-up for your heating system each year, catching potential problems before they become failures during peak-demand season.

Our Annual Maintenance Agreement formalizes that schedule and adds meaningful benefits for enrolled customers:

• Both furnace and air conditioner check-ups included in a single agreement
• Priority scheduling - enrolled customers move to the front of the line
• No overtime charges for after-hours emergency service calls
• 30-point inspection on each covered visit
• 10% discount on all parts and labor when repairs are needed

Coverage begins as soon as your system is approved and payment is received. A technician confirms the equipment is in good working order during a pre-agreement inspection, typically completed the same day.

What Sets H.J. Faust, Inc. Apart for Caledonia Homeowners

Our technicians are fully licensed, insured, factory-trained, and NATE-certified (North American Technician Excellence), meeting nationally recognized standards across heating, cooling, ventilation, and refrigeration. We’ve earned an Excellent rating based on hundreds of Google reviews, with customers consistently pointing to our promptness, clear communication, and thorough work. We’re also BBB accredited, reflecting our accountability to the customers and communities we serve.

What distinguishes our technical staff is the training pipeline behind them. Our mechanics come through the state-approved ABC (Associated Builders and Contractors) Apprentice Program, a five-year curriculum that combines classroom instruction with on-the-job training under direct Senior Mechanic supervision. Beyond that foundation, every field and office employee attends a minimum of four training sessions per year to stay current on new equipment, technologies, and processes.

We also believe in giving back to the communities that have trusted us for over 45 years. Each year, in partnership with Lennox, we participate in the Feel the Love program. We nominate a deserving household in our service area that needs a new furnace, then donate and install one at no cost to the recipient. On every job, our team recycles all eligible materials and disposes of the rest responsibly.
