Professional Electrical Installation Services You Can Trust
At R. H. Witt Heating & Sheet Metal, we understand that modern HVAC systems depend heavily on safe, reliable electrical connections. Founded by Richard H. Witt Jr. in 1966, we have spent decades perfecting the integration of electrical installation with heating, cooling, and ventilation systems. As a family owned and operated business located in Glenview, IL, we bring a personal commitment to every project, ensuring that the electrical components powering your comfort systems are installed with precision, care, and strict adherence to local and national codes.
Electrical installation is a critical component of virtually every HVAC project we undertake. Whether we are wiring a new high-efficiency furnace, connecting a central air conditioning unit, or installing smart thermostat systems, the electrical work must be executed flawlessly to ensure both performance and safety. Our team brings state-of-the-art computerized diagnostic equipment to every job, allowing us to identify potential issues before they become costly problems. We proudly serve homeowners and businesses throughout North Shore and Northwest Suburbs, delivering the same level of excellence that has earned us a customer satisfaction rating of 99%.
How Electrical Installation Connects to Your HVAC System
Every heating and air conditioning system requires a dedicated electrical infrastructure to function properly. This includes circuit breaker connections, dedicated wiring runs, proper grounding, and correctly rated disconnect switches. When we design comfort solutions, we analyze not only your equipment but also any potential problems with the building envelope that could impact your comfort or indoor air quality. The electrical installation is a foundational part of that analysis because undersized wiring, faulty breakers, or improper voltage can cause equipment failure, energy waste, and even fire hazards.
Our technicians evaluate your existing electrical panel capacity to determine whether it can support new HVAC equipment. Many older homes in Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL were built with 100-amp service panels that may not accommodate today’s high-efficiency heat pumps, air handlers, or multi-zone systems. In these cases, we coordinate the necessary upgrades to ensure your new system operates within safe electrical parameters. According to the Electrical Safety Foundation International, electrical failures contribute to more than 50,000 home fires annually in the United States, making professional installation an essential safeguard for your family and property.
