Whether your furnace stopped producing heat overnight or you’re planning a new construction project that needs HVAC from the ground up, our NATE-certified team delivers end-to-end solutions rather than just one piece of the puzzle.

Our HVAC services include:

Not sure whether your system needs repair or full replacement? Common signs that it’s time to call include no warm or cool air from the unit, unusual rattling or pinging sounds, a discolored pilot light, frequent short-cycling, and an unexplained spike in energy bills. When a system is aging or breaking down repeatedly, replacement can become more cost-effective than continued repairs. We can tell you honestly which direction makes sense for your situation.

What Sets H.J. Faust, Inc. Apart in Wind Lake

What’s different here is the depth of training behind every technician who walks through your door. Every mechanic we field is fully licensed, insured, factory-trained, and NATE-certified. NATE (North American Technician Excellence) certification is the nationally recognized standard for heating, cooling, ventilation, and refrigeration competency. It means the person diagnosing your system has tested knowledge, not just field experience.

We develop our technicians through our structured Internal Apprenticeship & Development Program, which combines structured classroom instruction with direct field experience under Senior Mechanic supervision. It’s how we develop mechanics who can handle complex installs and unusual diagnostic situations without guessing. On top of that, every field and office employee attends a minimum of four training sessions per year to stay current on new equipment, technologies, and code updates.

Our customer record reflects that investment. We’ve earned an Excellent rating from hundreds of Google reviews, with customers consistently pointing to our promptness, clear communication, and thorough workmanship. We’re also committed to honest repair-vs.-replace guidance: we start every visit with a full inspection and recommend what the system requires. We won’t push a replacement when a repair makes sense, and we won’t recommend a repair when replacement is clearly the better long-term value.

When something goes wrong at 11 p.m. in January, we’re ready. Our 24/7 emergency service means Wind Lake customers can get help when heating or cooling fails at the worst possible time. We also offer competitive pricing and flexible scheduling to keep service accessible.

Annual Maintenance Agreement

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 season can help reduce the risk of breakdowns during the hottest day in July or the coldest night in February. Regular preventive maintenance can also help extend equipment lifespan and support efficiency.

Our Annual Maintenance Agreement makes both visits easy and affordable. Enrollment includes:

• 30-point inspection covering both your furnace and air conditioner
• Priority scheduling—agreement members are served first
• No overtime charges for after-hours emergency calls
• 10% discount on all parts and labor when repairs are needed

Equipment must be in good working order at the time of registration, and coverage begins once the system is approved and payment is received. For Wind Lake customers who want to help protect their equipment investment year-round, the agreement is a straightforward way to do it.

Community Commitment in Wind Lake & Beyond

Each year, in partnership with Lennox, we participate in the Feel the Love program. We nominate a deserving household in our area that needs a new heating or cooling system and then donate and install one at no cost to the recipient. It’s one of the most direct ways we connect the work we do every day to the community around us.

We also 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 team recycles all eligible material and disposes of the rest responsibly to reduce our ecological footprint.
