HVAC Brands We Service

Systems & Units Serviced by Factory-Trained Technicians Since 1978

When your Carrier, Trane, or Goodman system needs attention, the technician you call should know that brand’s components, control boards, and common failure points, not just HVAC in general. H.J. Faust, Inc. has served Burlington, WI, homeowners and commercial properties since 1978, building an install base of more than 20,000 clients along the way. We install Lennox systems and service all major brands, whether or not we were the ones who originally installed the equipment. That covers everything from a single-family furnace repair to a commercial rooftop unit replacement. We also offer free estimates and same-day service to keep the process straightforward from the first call forward.

Brands We Install & Service in Burlington

We install Lennox and service every major HVAC brand on the market, including:

• American Standard
• Armstrong Air
• Carrier
• Bryant
• Daikin
• Goodman
• Honeywell
• Mitsubishi
• Rheem
• Trane
• YORK

If you bought these brands from us or anyone else, we can repair, maintain, or replace it. Brand-specific service matters because HVAC control boards, refrigerant configurations, and diagnostic protocols vary by manufacturer. A technician who knows a brand’s product line can identify failure modes accurately rather than working through a generic checklist.

Our service coverage spans the full range of system types:

• Gas furnaces
• Central air conditioners
• Heat pumps
• Boiler systems
• Mini-split systems
• Rooftop units (commercial)

Across all brands and system types, we handle:

• Heating and cooling repairs
• Routine seasonal maintenance
• System installation and replacement
• Refrigerant pressure diagnostics
• Capacitor and contactor inspection
• Blower motor and compressor service
• Thermostat calibration
• Heat exchanger integrity checks

If your current system isn’t meeting efficiency or performance expectations, Lennox offers an upgrade path worth considering. We can walk you through the options honestly, based on what your situation actually calls for, not on what carries the highest margin.

Factory-Trained Technicians with a No-Upsell Inspection Policy

Our technicians are fully licensed, insured, NATE-certified, and factory-trained. NATE certification (North American Technician Excellence) is the nationally recognized credential in heating, cooling, ventilation, and refrigeration. It means our techs have been tested against industry standards, not just trained in-house. Every field and office employee completes a minimum of four training sessions per year to stay current on new equipment and technologies.

We also train from the ground up. We develop our mechanics through our structured Internal Apprenticeship & Development Program, a multi-year curriculum combining classroom instruction with hands-on field work under direct Senior Mechanic supervision. That structured pipeline is how we keep our workforce among the most thoroughly trained in the area.

Every service call starts with a thorough inspection before we recommend anything. We don’t suggest a repair or replacement unless your system actually requires it. Hundreds of Google reviews back that up. Customers consistently point to our promptness, clear communication, and thorough work as reasons they return. We’re also BBB accredited and available 24/7 for emergency heating and cooling calls, with competitive pricing and flexible scheduling to fit your situation.

Annual Maintenance Agreement: Twice-Yearly Service with Priority Scheduling

We recommend a spring check-up for your air conditioning system and a fall check-up for your heating system each year. Catching small issues before the season peaks can help prevent the breakdowns that happen at the worst possible time. Our Annual Maintenance Agreement makes that easy.

Agreement benefits include:

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

The no-overtime-charge provision and the 10% parts-and-labor discount are the details that add up over time. If a repair comes up between scheduled visits, agreement members can pay less and wait less.
