Troy HVAC Services

Full-Service Heating & Cooling for Troy Homeowners & Businesses

Since 1978, H.J. Faust, Inc. has delivered reliable HVAC services to residential and commercial customers across southeastern Wisconsin, now serving Troy, WI, and the surrounding Walworth County area. Over more than four decades, we’ve built a regional install base of more than 20,000 clients, earned an Excellent rating from hundreds of Google reviews, and maintained our BBB accreditation. Our NATE-certified technicians are factory-trained, fully licensed, and insured, so every call, whether routine maintenance or an urgent repair, is handled by someone who meets nationally recognized standards in heating, cooling, ventilation, and refrigeration.

Troy residents can reach us any time at (262) 418-0700, including nights and weekends for heating and cooling emergencies.

Heating & Air Conditioning Services in Troy, WI

We handle the full range of HVAC work: furnace repair and replacement, air conditioning service, preventive maintenance, system upgrades, new construction, and design-build projects. We install Lennox systems and service all major brands, including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant, so no matter what equipment is in your home, we can work on it. We serve both residential and commercial customers.

Before we recommend any solution, we perform a thorough inspection. You won’t hear us push a replacement when a repair makes sense or suggest an upgrade your system doesn’t need. That inspection-first approach applies equally to a simple tune-up and a full system evaluation.

Common signs your heating or cooling system needs attention:

• Furnace blowing lukewarm or cool air
• AC running but not cooling the space
• Rattling, pinging, or unusual sounds during operation
• Pilot light that appears yellow or orange instead of blue
• System cycling on and off more frequently than usual
• A sudden, unexplained increase in energy bills

Wisconsin winters put serious demand on heating equipment. When a system starts showing these signs, prompt service can help prevent a minor issue from becoming a mid-January breakdown. If it’s already an emergency, our technicians are available around the clock: 24/7, with no overtime charges for agreement holders.

What Sets H.J. Faust, Inc. Apart

Technician quality is the single biggest variable in HVAC work, and we invest in ours differently than most. Our mechanics train through the state-approved Associated Builders and Contractors (ABC) Apprentice Program, a structured, five-year curriculum that combines classroom instruction with hands-on field work under direct Senior Mechanic supervision. That’s not a weekend certification course. It’s a multi-year commitment to developing real mechanical skill. 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.

Each year, we also participate in the Lennox Feel the Love program, nominating a deserving family in our service area for a free heating or cooling system, then donating and installing it at no cost to them. It’s a named, co-sponsored program directly tied to our work, and it reflects what we think a community-rooted company should do.

A few more reasons Troy residents call us:

• Honest repair-vs-replace guidance: Inspection first, recommendation second
• Competitive pricing and flexible scheduling to fit your timeline and budget
• Responsible material handling: We recycle all eligible material on every job and dispose of the rest properly

Annual Maintenance Agreement for Troy, WI Residents

We recommend a spring check-up for your air conditioning system and a fall check-up for your heating system each year. Scheduling maintenance before peak season means your equipment is ready when temperatures make it matter most, not failing on the hottest day in July or the coldest night in January.

Our Annual Maintenance Agreement covers both visits and includes a 30-point inspection, priority scheduling, no overtime charges for after-hours calls, and a 10% discount on all parts and labor when repairs are needed. Regular maintenance can help prevent breakdowns, support efficiency, and extend the working life of your equipment. It’s a cost-effective way to help protect your investment year after year.
