Keeping Chicagoland Comfortable — One Home at a Time

Trusted Heating & Sheet Metal Craftsmanship Since 1966

Your Trusted Partner for Complete Home Comfort

When it comes to keeping your home comfortable throughout every season, you deserve a team that brings decades of expertise and genuine care to every project. R. H. Witt Heating & Sheet Metal is a family owned and operated business located in Glenview, IL, founded by Richard H. Witt Jr. in 1966. For decades, we have been delivering reliable heating, cooling, and indoor air quality solutions to homeowners across North Shore and Northwest Suburbs. Our deep roots in this community mean we understand the unique climate challenges that come with harsh Midwest winters and humid summers, and we design systems that perform flawlessly year-round.

As a full-service heating and air conditioning contractor, we take pride in going beyond simple equipment installation. We specialize in designing comfort solutions that address not only your equipment but also analyze whether there are any potential problems with the building envelope that could impact your comfort or indoor air quality. This holistic approach means we look at insulation, ductwork, ventilation, and airflow dynamics to ensure every component of your home works together efficiently.

Heating and Cooling Services

Our core services encompass everything you need for dependable climate control. Whether you are installing a brand-new high-efficiency furnace, replacing an aging air conditioning system, or scheduling routine maintenance to keep your equipment running at peak performance, we handle it all. We serve homeowners throughout Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL and surrounding communities, bringing the same level of professionalism and attention to detail to every job, regardless of its size.

Modern HVAC technology has advanced significantly, with variable-speed compressors, modulating gas valves, and smart thermostat integration becoming standard features in premium systems. We stay current with these developments and use state-of-the-art computerized diagnostic equipment to solve comfort problems, address unhealthy air concerns, and identify the causes of high utility bills. This technology allows us to pinpoint issues quickly and recommend the most effective solutions rather than relying on guesswork.

Indoor Air Quality and Building Envelope Analysis

Indoor air quality has become a growing concern for homeowners, especially as modern construction techniques create tighter building envelopes that can trap pollutants, allergens, and excess moisture inside. Studies from the Environmental Protection Agency indicate that indoor air can be two to five times more polluted than outdoor air. We address these concerns through comprehensive assessments that evaluate your home’s ventilation, humidity levels, and filtration needs.

Our approach includes evaluating your ductwork for leaks, recommending appropriate air purification systems, and ensuring balanced airflow throughout your home. By treating the building envelope as part of the overall comfort equation, we deliver results that go far beyond what a standard equipment swap can achieve. Homeowners in Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL consistently benefit from this thorough methodology, enjoying better air quality, more consistent temperatures, and lower energy costs.

Custom Sheet Metal Fabrication

As our name suggests, custom sheet metal work is a foundational part of what we do. Properly designed and fabricated ductwork is essential to any high-performing HVAC system. Poorly sized or improperly sealed ducts can waste up to 30 percent of conditioned air before it ever reaches your living spaces. We design and fabricate custom ductwork in-house, ensuring precise fit and optimal airflow for your specific home layout.

This capability sets us apart from contractors who rely on generic off-the-shelf components. Custom fabrication allows us to tailor every transition, plenum, and branch line to your system’s exact specifications, reducing noise, improving efficiency, and extending equipment life.

Electrical Services You Can Trust

From panel upgrades to whole-home wiring, R. H. Witt offers comprehensive electrical services backed by the same craftsmanship and reliability our customers have counted on for over a century. Our team understands that electrical work isn’t just about flipping switches — it’s about the safety and comfort of your home and family. That’s why we approach every job, big or small, with the same meticulous attention to detail that has defined our reputation since 1966.

Whether you need a simple repair, a full electrical installation, or you’re planning a major renovation, our licensed professionals are equipped to handle it all. We stay current with the latest codes and technologies so you don’t have to worry — just trust that the job will be done safely, efficiently, and right the first time. Because at R. H. Witt, that’s not just a promise. It’s a tradition.
