Air Conditioning Services in Wheatland, WI

Wisconsin summers bring sustained heat and humidity that push cooling systems hard. When your air conditioner struggles to keep up, our NATE-certified technicians diagnose the problem before recommending a solution. We won’t recommend more than your system actually requires. Every call starts with a thorough inspection.

We install Lennox cooling systems and service all major brands, including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant. For spaces without existing ductwork or rooms that need independent temperature control, we also install mini split systems that deliver zoned comfort without major renovation. Our factory-trained technicians bring the same standard to routine maintenance, emergency repairs, and full system replacements.

Heating Services for Wheatland Homes & Commercial Properties

Wisconsin winters are long and unforgiving, and a furnace failure in January isn’t something you can put off until morning. Our team handles furnace and heat pump installation, repair, and maintenance for both residential and commercial customers. As with cooling, we service all major brands and install Lennox heating systems, and every recommendation follows a complete inspection of your existing equipment.

Heat pumps are worth considering if you want one system to handle both heating and cooling. Cold-climate models are designed to perform efficiently even in Wisconsin temperatures, and a dual-fuel configuration pairs a heat pump with a gas or propane furnace for backup on the coldest days. If you’re unsure which system fits your situation, we can walk you through the options based on your building, your usage, and your budget.

Annual Maintenance Agreement

Consistent maintenance is a reliable way to help avoid emergency breakdowns and extend the life of your equipment. We recommend a spring check-up for your air conditioner and a fall check-up for your furnace, and our Annual Maintenance Agreement makes both easy to manage.

Enrolled customers receive:

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

Signs Your Heating or Cooling System May Need Replacement

Not every problem calls for a new system. We start with a thorough inspection and won’t recommend replacement when a repair is the right answer. 

That said, some patterns are worth knowing:

• Age: Systems between 10 and 15 years old are typically less efficient and more prone to breakdowns, even with regular maintenance.
• Repair costs: When the cost to repair a system approaches half the price of a new one, replacement is often the more economical path.
• Inconsistent temperatures: If rooms in your home or business heat or cool unevenly, the system may no longer distribute air adequately.
• R-22 refrigerant: R-22 has been federally phased out of production and import. Systems still relying on it face shrinking refrigerant availability, and replacement with equipment running an approved refrigerant may be worth considering.

Why Wheatland Customers Choose H.J. Faust, Inc.

Our technicians are fully licensed, insured, factory-trained, and NATE-certified. NATE (North American Technician Excellence) is the nationally recognized credentialing standard for heating, cooling, ventilation, and refrigeration work. Beyond certification, every field and office employee completes a minimum of four training sessions per year to stay current on equipment and process changes.

What sets our training apart is the pipeline behind it. We develop our technicians through our structured Internal Apprenticeship & Development Program, which combines structured classroom instruction with direct field experience under Senior Mechanic supervision. 

We’re also BBB-accredited and have earned an Excellent rating from hundreds of Google reviews. Customers regularly mention our promptness, clear communication, and thorough work. Those reviews reflect what we’re focused on: showing up on time, explaining what we found, and doing the job correctly.

Our community involvement is tied directly to the work we do. Each year, through the Lennox Feel the Love program, we nominate a deserving household in our community that can’t afford a new furnace, then donate and install one 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, and support local schools, athletic programs, and the Chamber of Commerce. Our crews recycle all eligible material on every job and dispose of the rest responsibly.
