Our Heating Services in Salem

Wisconsin winters don't give much warning when a furnace starts to fail. Our NATE-certified, factory-trained technicians are available around the clock for emergency heating calls, so a breakdown in January doesn't mean a cold night waiting for help. Every service visit starts with a thorough inspection. We won't recommend a repair or a replacement until we understand exactly what the system needs, and we don't suggest more than your situation actually requires.

We install Lennox heating systems and service all major brands, including Carrier, Trane, Daikin, Goodman, Honeywell, and Bryant. When a system is aging or requiring increasingly frequent repairs, we can walk you through an honest comparison so you can make a confident decision. A fall check-up each year is one of the best ways to catch developing issues before they become emergency failures, and it's something we recommend to heating customers we serve.

Our Cooling Services in Salem

Southeastern Wisconsin summers combine real heat with high humidity, and that combination puts significant stress on air conditioning equipment. Refrigerant leaks, failed capacitors, frozen evaporator coils, and electrical faults are among the most common problems we diagnose, and our technicians are fully licensed, insured, and trained to address all of them. For urgent situations, 24/7 emergency cooling service is available.

As with heating, we start every cooling call with a full inspection before making any recommendation. We service all major AC brands and install Lennox cooling systems. A spring check-up each year can help your system handle peak-season demand with fewer unexpected failures, and it's an effective step you can take to support equipment life and efficiency.

HVAC System Types We Install & Service

Salem-area customers have more equipment options than ever, and we're equipped to install and service the full range:

• Heat pumps provide heating and cooling year-round from a single system by transferring heat rather than generating it
• Ductless mini splits deliver room-by-room temperature control and work well where ducted systems aren't practical
• Packaged units house all components in one outdoor cabinet, a practical configuration for homes with limited mechanical room space
• Hybrid systems pair a heat pump for mild-weather efficiency with a gas furnace that handles the deep cold Wisconsin winters regularly produce

Indoor Air Quality Solutions

Comfort isn't only about temperature. We offer a full range of indoor air quality products: air purifiers, humidifiers, dehumidifiers, UV air sanitizers, ventilation systems, and radon mitigation services to address the allergens, humidity imbalances, and pollutants that affect your home or building year-round.

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

Our technicians are NATE-certified, factory-trained, fully licensed, and insured. NATE certification means they've passed nationally recognized exams in heating, cooling, ventilation, and refrigeration. It's not a credential that comes from a weekend course. We're also BBB accredited and have earned an Excellent rating across hundreds Google reviews, with customers consistently pointing to our promptness, clear communication, and thorough work.

Training runs deeper than many companies in this region. Every field and office employee attends a minimum of four training sessions per year. Our mechanics are also trained through the state-approved ABC (Associated Builders and Contractors) Apprentice Program, a multi-year curriculum that combines classroom instruction with hands-on field work under direct Senior Mechanic supervision. That structured pipeline is how we maintain the caliber of work our customers have come to expect over more than four decades.

Our Annual Maintenance Agreement covers both a furnace check-up and an air conditioner check-up each year, along with priority scheduling, no overtime charges for after-hours calls, a 30-point inspection, and a 10% discount on all parts and labor when repairs are needed. It's a practical way to help protect your investment and keep your system running efficiently through every season.

We also believe in giving back to the communities we serve. Each year, we participate in the Lennox Feel the Love program, nominating a deserving household in the Salem area and donating a complete furnace installation at no cost to the recipient. We recycle all eligible material on every job and dispose of the rest responsibly.

Salem HVAC Frequently Asked Questions

How Often Should My HVAC System Be Serviced?

We recommend two maintenance visits per year: one in the spring for your air conditioning system and one in the fall for your heating system. This schedule can help technicians catch developing problems before they become emergency failures and keep your equipment running efficiently.

How Often Should I Change My Air Filter?

Most homes benefit from a filter change every one to three months. If you have pets or allergy sufferers in the household, more frequent changes may help your system and your indoor air quality.

What's Included in the Annual Maintenance Agreement?

The agreement includes a furnace check-up, an air conditioner check-up, a 30-point inspection, priority scheduling, no overtime charges for after-hours service calls, and a 10% discount on all parts and labor for any repairs needed during the agreement period.
