Mechanics Trained to a Standard Most HVAC Contractors Don’t Match

What separates H.J. Faust, Inc. from other Burlington HVAC contractors starts with how we develop our workforce. Our mechanics train through our structured Internal Apprenticeship & Development Program, which is a curriculum that combines classroom instruction with hands-on field work under direct Senior Mechanic supervision. It’s a structured, in-depth pipeline that produces installers who understand the work, not just the steps.

Beyond that foundation, every field and office employee completes a minimum of four training sessions per year to stay current on new equipment, technologies, and processes. That ongoing investment shows up in our customer feedback: we’ve earned an Excellent rating based on hundreds of Google reviews, with customers consistently noting promptness, clear communication, and thorough work. We’ve also maintained BBB accreditation since January 1, 1997.

Emergency situations don’t wait for business hours. Our technicians are available 24/7 for heating and cooling calls, and we offer competitive pricing and flexible scheduling to fit your timeline. Every installation is backed by our 100% satisfaction guarantee.

Our AC Installation Process in Burlington, WI

A properly installed air conditioner starts long before the equipment arrives. Our team begins with a detailed evaluation of your home, factoring in square footage, insulation, window orientation, existing ductwork, and electrical connections. We then install the unit to manufacturer specifications and clean up fully before leaving. Meeting manufacturer specs isn’t just good practice. It’s required to keep your equipment warranty valid. If your system ever does develop a problem after installation, our AC repair team is available when you need us.

Types of AC Systems We Install

The right system depends on your home’s layout, existing infrastructure, and how you use your space. We install three primary system types and help you evaluate which fits best.

Central Air Conditioning
Central AC uses an outdoor condensing unit connected to indoor air handlers through ductwork to cool the entire home from a single system. It’s the most common residential configuration and works well in homes with existing duct infrastructure.

Heat Pumps
Heat pumps move heat rather than generate it, which can make them more energy-efficient than resistive systems in moderate climates. Because they provide both heating and cooling, a heat pump can replace two systems with one, which is a practical option for Wisconsin homeowners looking to simplify equipment management year-round.

Ductless Mini-Split Systems
Mini-splits connect one outdoor unit to one or more indoor air handlers without requiring ductwork. Each indoor handler operates independently, allowing zone-level temperature control room by room. They’re well-suited to homes without existing ducts, room additions, or spaces that need targeted cooling the central system can’t reach.

When to Replace Your AC Instead of Repairing It

Repair is often the right call, and we’ll tell you when it is. But some systems have reached a point where continued investment in repairs doesn’t make financial sense. Here are five signals we commonly see in Burlington homes that indicate replacement deserves a serious look.

• Age Over 10–15 Years: Systems in this range lose efficiency gradually and become more prone to component failures. Even a functioning older unit may be costing you more to run than a replacement would over time.
• Escalating Repair Frequency: One repair is routine. A pattern of repairs, especially when costs begin approaching a meaningful fraction of a replacement unit’s price, shifts the math toward replacement.
• Rising Energy Bills Without a Usage Change: A steady climb in summer electricity costs, with no corresponding change in how you use the home, often points to a system that’s losing efficiency and working harder to deliver the same results.
• Uneven Cooling Across Rooms: Inconsistent temperatures from room to room can indicate an aging system struggling to maintain consistent output, or a unit that was never correctly sized for the home in the first place.
• Outdated Refrigerant: Older systems may use refrigerants being phased out under EPA regulations. As those refrigerants become harder to source, repair costs rise, and in some cases, the system simply can’t be serviced cost-effectively any longer.

AC Installation Costs, Financing & Wisconsin Rebates

Installation pricing varies based on home size, existing ductwork, the efficiency rating of the chosen unit, and installation complexity. High-efficiency systems carry a higher upfront cost, but lower operating expenses can offset that difference over time. We offer financing options to help make the investment more manageable. Contact us for current details.

Burlington homeowners may also qualify for meaningful cost reductions through available incentive programs. Wisconsin’s HEAR (Home Electrification and Appliance Rebate) program, federal energy-efficiency tax credits, Focus on Energy rebates, utility-specific promotions, and Lennox manufacturer promotions can all reduce what you pay for qualifying equipment. Our team can help you identify which systems may qualify.

Protecting Your Investment After Installation

A new AC system is a long-term investment, and routine maintenance is what keeps it performing at that level. We recommend a spring check-up for your air conditioning system each year to help prevent breakdowns before peak cooling season, maintain efficiency, and support equipment life. Consistent servicing also supports manufacturer warranty coverage by demonstrating the system has been properly maintained.

Our Annual Maintenance Agreement includes both a furnace check-up and an air conditioner check-up, priority scheduling during busy seasons, no overtime charges for after-hours calls, a 30-point inspection, and a 10% discount on all parts and labor when repairs are needed.

Frequently Asked Questions

When’s the Best Time to Schedule AC Installation?

Spring and fall tend to be ideal. Milder weather lets you plan ahead before summer demand peaks, and scheduling flexibility is typically better. That said, installation is available year-round, so don’t wait if your current system has already failed.

Will My Existing Ductwork Be Compatible with a New System?

In many like-for-like replacements, existing ductwork can be reused. Switching system types, upgrading to a significantly different unit size, or moving to a ductless configuration may require modifications. Our team evaluates your current ductwork as part of the home assessment.

Does My Thermostat Need to Be Replaced Too?

Not always. Many existing thermostats are compatible with new AC units. Upgrading to a programmable or smart thermostat at the same time can improve efficiency and control, and our team can advise whether your current thermostat is the right fit for the new system.

How Do I Prepare My Home for Installation Day?

Clearing the area around the installation site and keeping pets and small children away from the work area makes the process smoother. Our team can walk you through any specific preparation steps when we schedule your appointment.

Can I Install a New Air Conditioner Myself?

AC installation requires EPA refrigerant handling certification, specialized tools, and electrical work that carries real safety risk. DIY installation also typically voids manufacturer warranties and risks improper sizing. We strongly recommend using a licensed, certified contractor.
