Considering a New Heater? Count on Our Furnace Installation Team

Whether you’re outfitting a newly constructed home or replacing a furnace that’s no longer keeping up, our team has the right Lennox system and the experience to install it correctly. Furnaces over 15 years old, needing frequent repairs, or driving up your energy bills are often better candidates for replacement than continued service. Our certified Home Comfort Advisors can help you make that call with confidence.

Every furnace installation starts with a Comfort Review at your home. During this assessment, we’ll walk through your options for adding to, upgrading, or changing your furnace and give you clear information about installation costs. Once you’ve chosen the right solution, we schedule an installation day and connect your new furnace to your existing air ducts, gas lines, and electrical system for dependable, efficient operation from day one.

Restore Your Heating System’s Efficiency With Furnace Repair Services

When your furnace stops working reliably, you need a diagnosis you can trust. H.J. Faust, Inc. has spent more than 40 years repairing furnaces throughout Burlington, WI, and we bring that depth of experience to every service call. We repair gas, electric, and oil furnaces from all major manufacturers, so whether your system is Lennox, Carrier, Trane, or any other brand, we can service it.

Over the years, we’ve helped homeowners resolve furnace problems such as:

• Pilot light issues
• Unusual sounds
• Faulty thermostats
• Failing burners
• Improper airflow
• A constantly running blower

Safety inspections are part of every repair visit. Our technicians are trained to identify carbon monoxide leaks and perform heat exchanger inspections. A cracked heat exchanger can allow combustion gases to enter your home’s air supply, making it one of the most important safety checks we perform. Our heating services are built to address both the immediate problem and the underlying risks.

Keep Your Unit Running With Furnace Maintenance Services

When was the last time you had your furnace serviced? Not repaired or replaced, but given a real tune-up. We recommend one fall furnace check-up and one spring air conditioning check-up each year. Staying on that schedule can help prevent costly breakdowns, support energy-efficient heating through the winter, and help keep your equipment warranty valid.

During a maintenance visit, our technicians inspect, clean, and lubricate all vital components. For homeowners who want to take that a step further, our Annual Maintenance Agreement covers both your furnace and air conditioner check-ups and adds meaningful protections:

• 30-Point Inspection: A comprehensive evaluation of your system’s key components
• Priority Scheduling: You move to the front of the line when you need service
• No Overtime Charges: After-hours service calls are billed at standard rates
• 10% Discount on Parts and Labor: Applied to any repairs needed during the agreement period

If it’s been a while since your last tune-up, call our furnace service technicians in Burlington, WI, today. A late maintenance visit is always better than skipping one entirely.

FAQs About Broken Furnace Units

How Often Should I Have My Furnace Serviced?

Ideally, you should schedule an annual furnace service before the winter season begins. However, even if it’s the middle of winter and you haven’t had your system inspected yet, it’s still better to request a maintenance appointment late than to skip it entirely. Annual service helps catch small issues before they become costly repairs and can help keep your warranty current.

Why Is My Furnace Running but Not Producing Heat?

Several things can cause a furnace to run without delivering warm air: a clogged filter blocking airflow, a thermostat set incorrectly or malfunctioning, a burner that isn’t igniting, a blower motor problem, or issues with your ductwork reducing heat delivery. A technician can diagnose the exact cause quickly and get your system back on track.

How Do I Know Whether to Repair or Replace My Furnace?

Furnaces over 15 to 20 years old, requiring frequent repairs, or producing noticeably higher energy bills are strong candidates for replacement. If repair costs are approaching half the price of a new system, replacement often makes more financial sense. Our technicians can give you an honest assessment without pressuring you toward the more expensive option.

What Should I Do If I Smell Gas or a Burning Odor Near My Furnace?

Leave your home immediately. Don’t turn any lights or switches on or off. Once outside, call your gas company or 911 before contacting H.J. Faust, Inc. promptly. A gas odor near your furnace is a potential emergency, and utility and emergency personnel need to respond first.

What Do Different Furnace Noises Mean?

Banging or popping sounds often indicate duct expansion or delayed ignition. Grinding or scraping points to worn motor bearings that need immediate attention. Whistling or squealing typically signals restricted airflow or a blower motor issue. Any persistent or new noise is worth having a technician evaluate before it becomes a larger problem.

Does H.J. Faust, Inc. Service Other Heating Systems Besides Furnaces?

Yes. Our technicians also service boilers, heat pumps, and ductless mini-split systems.
