HVAC Repair Services

When a heating or cooling system fails, the first thing we do is inspect it thoroughly before recommending anything. We diagnose and repair furnaces, air conditioners, heat pumps, and related components, and we don’t recommend more than your system actually requires. That commitment to honest assessment is one of the reasons customers keep calling us back. If a repair makes sense, we’ll repair it. If a replacement is the better long-term call, we can explain why.

Furnace failures during a Wisconsin cold snap aren’t just uncomfortable. They can be a genuine safety concern. Our technicians are on call around the clock for exactly those moments. Common repair work includes heat exchanger inspection, refrigerant evaluation, airflow diagnostics, and air handler checks.

HVAC Installation & System Upgrades

We install Lennox systems and service all major brands, including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant. Our installation work spans new construction, design-build projects, full system replacements, and targeted upgrades. We also handle sheet metal fabrication in-house, which means we can deliver end-to-end solutions rather than coordinating around a separate trade.

Proper system sizing is one of the most important variables in any installation. An oversized or undersized system can cycle inefficiently, wear out faster, and cost more to run. We size and configure equipment to match your home or building’s actual load, not the closest standard option. Competitive pricing and flexible scheduling make it easier to move forward when you’re ready. Explore our installation services: heat pumps, mini split systems, and central air conditioners.

Indoor Air Quality Solutions

Comfort isn’t only about temperature. High outdoor humidity in Wisconsin summers can push indoor moisture levels up, creating conditions that affect air quality and overall comfort. We inspect air filters, ductwork, and moisture levels as part of our IAQ evaluation and can recommend whole-home air purifiers and humidity control systems tailored to your situation.

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

Every technician we send to your home is fully licensed, insured, factory-trained, and NATE-certified. NATE (North American Technician Excellence certification) is an independent, knowledge-based credential covering specific equipment categories in heating, cooling, ventilation, and refrigeration. It’s a nationally recognized standard.

Beyond individual credentials, our workforce pipeline is what separates us from competitors. We develop our mechanics through the state-approved ABC (Associated Builders and Contractors) Apprentice Program, a five-year curriculum that combines classroom instruction with hands-on field work under direct Senior Mechanic supervision. Every field and office employee also completes a minimum of four training sessions per year to stay current on new equipment, technologies, and processes. That structured investment in our team shows up in the quality of every job.

Customers notice. We’ve earned an Excellent rating from hundreds of Google reviews, with consistent feedback about promptness, clear communication, and thorough work. We also maintain BBB accreditation, reflecting our accountability to the customers and communities we serve.

Annual HVAC Maintenance Agreements

We recommend a spring check-up for your air conditioning system and a fall check-up for your heating system each year. Catching worn components before peak demand season is a reliable way to help avoid an emergency breakdown when you need your equipment most.

Our Annual Maintenance Agreement makes that easy. It includes both a furnace check-up and an air conditioner check-up, priority scheduling, no overtime charges for after-hours calls, a 30-point inspection, and a 10% discount on all parts and labor when repairs are needed. It’s a straightforward program with concrete benefits, not just a reminder to schedule.

Rooted in the Community

Each year, in partnership with Lennox, we participate in the Feel the Love program. We nominate a deserving household in our community that can’t afford new heating and cooling equipment, then donate and install a system at no cost to the recipient. We also sponsor the Tall Tales Music Festival, the Burlington Turkey Trot benefiting Love, Inc., and the Transitional Living Center of Burlington, while supporting local schools, athletic programs, and the Chamber of Commerce. On every job, we recycle all eligible material and dispose of the rest responsibly.
