What Lennox Premier Dealer Status Means for You

Lennox doesn't hand out Premier Dealer status freely. Dealers have to meet ongoing standards around technician training, customer service, and business practices, and Lennox continues to review that standing periodically rather than granting it once and forgetting about it.

For homeowners, that Premier Dealer badge translates into a few concrete things: 

• Our technicians train directly on Lennox equipment rather than learning it secondhand
• We carry the parts and knowledge to back Lennox's manufacturer warranties properly
• We're held to a higher bar (such as in certifications and customer ratings) than a dealer who simply resells the brand without the same accountability.

It's one of the reasons we can stand behind every Lennox system we install.

Why Burlington Residents Trust H.J. Faust, Inc. for HVAC Services

Our technicians are fully licensed, insured, NATE-certified, and factory-trained on Lennox equipment. They’ve completed Lennox’s own curriculum covering installation, design, communication, and service. Every field and office employee also attends a minimum of four training sessions per year to stay current on new equipment and evolving technologies.

Our technicians participate in our structured Internal Apprenticeship & Development Program. This multi-year curriculum pairs classroom instruction with hands-on field work under direct Senior Mechanic supervision. It is a structured pipeline that produces some of the most thoroughly prepared HVAC mechanics in the area.

What sets our team apart:

• NATE-certified and factory-trained on Lennox systems
• Four-plus training sessions per employee per year
• Internal Apprenticeship & Development Program participation
• Excellent rating from 1,400+ Google reviews
• BBB accredited since 1997
• 24/7 emergency heating and cooling service
• Services all major brands for repairs
• Installs Lennox exclusively for new system replacements

We also begin every job with a thorough inspection before recommending any solution. If your system only needs a repair, that’s what we’ll tell you. You won’t hear us recommend more than your equipment actually requires.

Lennox Systems We Install

Lennox builds several distinct product families, and part of our job is helping you land on the right one for your home, your budget, and how you actually use your space.

• Dave Lennox Signature® Collection: Lennox's flagship line, built for homeowners who want the highest efficiency ratings and the most advanced comfort features Lennox offers, including systems that pair together into a fully coordinated whole-home setup.
• Lennox Elite® Series: A strong performer that offers high-efficiency heating and cooling for homeowners who want a noticeable upgrade in comfort and performance without paying for every top-tier feature.
• Lennox Merit® Series: Solid, dependable equipment for homeowners who want reliable heating and cooling at a more accessible price point.
• Healthy Climate® Solutions: Indoor air quality equipment that includes air purification and high-efficiency filtration, designed to work alongside your central heating and cooling system for cleaner air throughout your home.

Not sure which tier fits your home? Our technicians will walk you through the tradeoffs during your consultation based on your home's size, insulation, and comfort priorities.

Why Lennox Systems Perform Well in Wisconsin Climates

Wisconsin’s winters hit hard and summers bring real heat. These conditions put HVAC systems through meaningful seasonal extremes. Lennox engineers its equipment for durability in climates with significant temperature swings, and its top-tier models reach SEER ratings of 25 or greater, offering potential efficiency gains on both ends of the season. Lennox systems also run quieter than many industry-standard units and support smart thermostat integration, including remote temperature adjustment and programmable scheduling from your phone. Our AC installation technicians can walk you through which system tier and configuration fits your home’s specific needs.

Why H.J. Faust, Inc. Recommends Lennox

We work on every major brand, so choosing Lennox as our primary partner wasn't arbitrary. A few things kept standing out: Lennox's efficiency ratings consistently rank among the highest in the industry, which matters in a climate like ours where heating and cooling systems run hard most of the year. Their equipment is also built with long-term reliability in mind, which means fewer surprise breakdowns and lower lifetime costs for the homeowner, not just a lower price tag on installation day. And because we're a Premier Dealer, we get direct access to Lennox training, support, and parts availability, which lets us back up what we install rather than just installing it and hoping for the best. When we recommend a Lennox system, it's because we'd put one in our own home.

Lennox HVAC Installation in Burlington

Our factory-trained technicians manage every step of the process, from permit work and equipment configuration to the final walkthrough, where we show you how to use every feature your new system includes.

Before any equipment is selected, we conduct a thorough home evaluation covering insulation, window placement, sunlight exposure, and your home’s heating and cooling load. Proper sizing matters: an oversized or undersized unit can short-cycle or run continuously, affecting both comfort and efficiency. You’ll receive an upfront quote before work begins, and every installation meets Lennox manufacturer specifications.

Financing Your New Lennox System

A new furnace or air conditioner is a real investment, and we offer financing options to help spread out the cost. As an example of current terms: a financed amount of $8,578 for a furnace and air conditioner installation, which covers professional installation, all materials, and permits, is available over a 132-month term at 9.99% APR (Plan 943), subject to credit approval through Synchrony. This is a limited-time offer, and terms can change, so ask our team for the most current financing options and rates when you call.

Lennox HVAC Repair in Burlington

When a Lennox system stops performing, our technicians diagnose the problem first, explain what they found in plain terms, and present a repair plan before any work proceeds.

We address the full range of system issues, including but not limited to:

• Unusual noises
• Temperature inconsistencies
• Complete shutdowns

Our heating and AC repair solutions are available 24 hours a day, seven days a week, so Burlington homeowners can get help during a breakdown. Because we start with a full inspection, you can count on honest repair-versus-replace guidance, not a recommendation shaped by what’s most profitable.

Lennox Thermostat Installation & Troubleshooting

A malfunctioning thermostat can mimic HVAC system problems, causing short-cycling, temperature inconsistency, or failure to respond to scheduling changes. Lennox offers thermostat options ranging from basic programmable models to advanced smart units with remote access and precise temperature zoning via smartphone. If your current thermostat isn’t performing or you’re ready for a new thermostat installation, our technicians can help you find the right fit and configure it correctly.

Annual Maintenance for Your Lennox System

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 a seasonal peak can help prevent breakdowns, keep efficiency high, and extend equipment life.

Our Annual Maintenance Agreement covers both visits and includes:

• 30-point inspection covering all major system components
• Priority scheduling so you’re not waiting in line during busy seasons
• No overtime charges for after-hours calls
• 10% discount on all parts and labor when repairs are needed

Each maintenance visit includes cleaning essential components, checking for wear, inspecting air filters, and confirming all parts are in good working order.

Community Roots in Burlington, Wisconsin

Each year, we participate in the Lennox Feel the Love program. We nominate a Burlington-area household in need and then donate and install a new heating or cooling system at no cost to the recipient. It’s a commitment that goes beyond the transaction and connects directly to the work we do every day.

Our community involvement extends further: we sponsor the Tall Tales Music Festival, the Burlington Turkey Trot benefiting Love Inc., and the Transitional Living Center of Burlington, while supporting local athletic programs, schools, and the Chamber of Commerce. On every job, we recycle all eligible material and dispose of the rest responsibly.
