What Burlington Businesses Expect From an HVAC Partner

Commercial HVAC demands more than technical competence; it demands accountability. When a heating or cooling system fails at your business, you're dealing with uncomfortable customers, disrupted employees, and potential inventory or equipment risk. That's why every technician we dispatch is fully licensed, insured, factory-trained, and NATE-certified. NATE certification represents a nationally recognized benchmark in heating, ventilation, cooling, and refrigeration, and it's the standard every member of our field team meets.

We've held BBB accreditation since 1997, and hundreds of Google reviews reflect a consistent pattern: we arrive on time, explain our findings honestly, and complete work thoroughly. That same reputation earned in residential service extends to every commercial account we serve.

Before we recommend any repair or replacement, we conduct a full system inspection. Our technicians don't suggest work that isn't warranted. To stay current on evolving commercial equipment and efficiency standards, every team member completes a minimum of four formal training sessions per year. When something goes wrong outside business hours, our emergency service line is available around the clock, because HVAC failures rarely wait for Monday morning.

Commercial HVAC Systems We Install & Service

H.J. Faust, Inc. installs Lennox commercial equipment and services all major brands, including Carrier, Trane, Daikin, Goodman, Bryant, and Honeywell. Whether your building is running a system we installed or inherited equipment from a previous owner, we can work on it.

Commercial heating systems:

  • Rooftop packaged units
  • Furnaces
  • Boilers
  • Heat pumps
  • Ductless mini-split systems
  • Unit heaters

Commercial cooling systems:

  • Central air conditioning
  • Packaged units
  • Heat pumps
  • Ductless mini-split systems
  • Air handlers

Beyond equipment installation and repair, we handle ductwork inspection and modification, programmable and smart thermostat integration, zoning controls for multi-room or multi-tenant spaces, and indoor air quality solutions including filtration, purification, and ventilation systems. Maintaining clean, well-circulated air matters in any commercial environment, especially in restaurants, medical offices, and high-traffic retail spaces.

Planned Maintenance for Commercial Properties

Unplanned HVAC failures are expensive for any business. Lost productivity, emergency service premiums, and the ripple effects on staff and customers add up quickly. Consistent preventive maintenance is the most effective way to reduce that risk.

We recommend a spring inspection for your cooling equipment and a fall inspection for your heating systems each year. Seasonal check-ups identify developing issues before they become failures, help maintain equipment efficiency, and support longer system lifespan.

Our Annual Maintenance Agreement is built around that two-visit schedule. Each visit includes a 30-point inspection of the covered equipment. Agreement holders receive priority scheduling when service is needed, no overtime surcharges for after-hours emergency calls, and a 10% discount on parts and labor for any repairs performed throughout the year. For business owners managing tight operational budgets, that predictability has real value.

Trained HVAC Technicians, Every Time

The quality of an HVAC company comes down to the people doing the work. We develop our technicians through our structured Internal Apprenticeship & Development Program, which combines structured classroom instruction with direct field experience under Senior Mechanic supervision. That pipeline produces technicians who are prepared to work on the full range of commercial equipment and building configurations our clients operate.

Ongoing training doesn't stop at certification. Each technician participates in a minimum of four formal training sessions annually to stay current on new equipment, updated service procedures, and changing efficiency standards. When we send a mechanic to your property, they've earned their place on that truck.

Serving Burlington & Surrounding Communities

Our commercial clients are located throughout Racine, Walworth, and Kenosha counties. Whether you operate a single-location small business in downtown Burlington or manage a multi-suite office building in the surrounding region, we have the crew size and equipment access to handle the work.

We also take our community role seriously. Each year, alongside Lennox, we participate in the Feel the Love program, donating and installing new HVAC equipment for a deserving local recipient at no cost. We sponsor many other events and causes, and we actively support local schools, athletic programs, and the Chamber of Commerce. On every job, we recycle all eligible materials and handle disposal responsibly.

Commercial HVAC FAQs

How Do I Determine Whether Commercial Equipment Needs Repair or Replacement?

The answer depends on the equipment's age, repair history, and current condition. Systems older than 10 to 15 years that are experiencing recurring breakdowns often cost more to maintain than to replace, but that assessment requires a proper inspection. We won't recommend capital expenditure without one.

How Often Should Commercial HVAC Systems Be Serviced?

Twice annually is the standard recommendation: a spring inspection for cooling equipment and a fall inspection for heating systems. Businesses with higher-demand environments, such as commercial kitchens, server rooms, or high-occupancy retail, may benefit from additional check-ins. Our Annual Maintenance Agreement covers both seasonal visits and includes priority response and repair discounts.

Do You Work on Systems You Didn't Install?

Yes. We service all major commercial brands regardless of who performed the original installation. If you've recently acquired a property or are switching providers, we're equipped to pick up maintenance on existing equipment.
