NATE-Certified Technicians Trained Through a Five-Year Program

Not every HVAC company invests in its mechanics the way we do. Every technician on our team is fully licensed, insured, factory-trained, and NATE-certified. NATE (North American Technician Excellence) is the largest nonprofit HVACR certification program in the United States. It means the person arriving at your door has demonstrated competency well beyond the basics.

What sets our training pipeline further apart is the Associated Builders and Contractors (ABC) Apprentice Program. This state-approved, five-year curriculum combines classroom instruction with hands-on field work under direct Senior Mechanic supervision. It’s how we develop mechanics who don’t just follow steps. They understand systems. Every field and office employee also completes a minimum of four training sessions per year to stay current on new equipment, technologies, and processes.

We hold BBB accreditation and have earned an Excellent rating based on hundreds of Google reviews. Customers consistently point to our promptness, clear communication, and thorough work. Before we recommend any repair or replacement, we start with a detailed inspection. We won’t suggest more than your system requires.

Heating & Cooling Services for Trevor Homes & Businesses

We install Lennox systems and service all major brands, including Carrier, Daikin, Goodman, Honeywell, Trane, and Bryant. Whatever’s running in your home or business, we can work on it.

Our HVAC services include:

• Furnace repair and installation
• Air conditioning repair and replacement
• Heat pump installation and service
• Ductless mini split installation and maintenance
• Indoor air quality solutions
• Whole-home humidifiers and dehumidifiers
• Air purification and advanced filtration
• Commercial HVAC work
• 24/7 emergency service

Heat pumps are worth a closer look for Trevor homeowners wanting year-round efficiency. A dual-fuel configuration (pairing a heat pump with a gas furnace backup) can handle Wisconsin’s coldest stretches without sacrificing the efficiency benefits heat pumps offer in milder weather. For spaces without existing ductwork, like finished basements or home additions, ductless mini splits are a flexible solution we install and maintain regularly.

Indoor air quality matters in Wisconsin’s climate. Tightly sealed homes in winter and high outdoor humidity in summer create conditions where whole-home humidifiers and dehumidifiers, and air filtration systems can make a real difference in how your home feels and how cleanly the air circulates.

Annual Maintenance Agreement for Trevor Homeowners

The most common cause of mid-season HVAC failures is skipped maintenance. We recommend one spring check-up for your air conditioning system and one fall check-up for your heating system every year, before peak demand hits and wait times grow.

Our Annual Maintenance Agreement makes that easy. Here’s what’s included:

• Furnace and air conditioner check-ups — both systems covered in one annual agreement
• 30-point inspection on each visit
• Priority scheduling when you need service
• No overtime charges for after-hours emergency calls
• 10% discount on all parts and labor when repairs are needed

Enrollment requires the system to be in good working order. A pre-agreement inspection confirms eligibility, and coverage begins the same day the system is approved and payment is received. Regular maintenance also supports system efficiency, extends equipment lifespan, and may support eligibility for energy rebates on qualifying Lennox installations.

Invested in Trevor & the Communities Around It

Each year we participate in the Lennox Feel the Love program, nominating a deserving local household in need and donating and installing a new system at no cost. We also sponsor the Tall Tales Music Festival, the Burlington Turkey Trot benefiting Love, Inc., and the Transitional Living Center of Burlington, while supporting local schools, athletic programs, and the Chamber of Commerce. On every job, we recycle all eligible material and dispose of the rest responsibly.

Trevor HVAC Frequently Asked Questions

How Often Should I Have My HVAC System Serviced?

Twice a year is the standard recommendation: a spring check-up for your air conditioning system before cooling season and a fall check-up for your heating system before winter. Staying on schedule reduces the chance of breakdowns during the periods when your system is working hardest.

How Long Do Furnaces and Air Conditioners Typically Last?

With regular maintenance, many furnaces and air conditioners last 15 to 20 years. As systems age, efficiency tends to decline. If your equipment is approaching that range and requiring frequent repairs, a replacement conversation is worth having. We can give you an honest assessment either way.

What Should I Check Before Calling for Service?

Start with your thermostat settings and make sure it’s set to the correct mode and temperature. Check your circuit breaker to confirm the system hasn’t tripped a breaker. If those check out and the problem continues, call us. Anything beyond that point is best handled by a professional.

What Are Signs I Should Call for HVAC Service?

Uneven temperatures between rooms, unexpected spikes in your energy bill, unusual sounds like banging, rattling, or squealing, short cycling (the system turning on and off rapidly), weak airflow, and difficulty holding your set temperature are all signs something needs attention. Don’t wait until a minor issue becomes an emergency.
