Professional Air Conditioning Service You Can Count On
When summer temperatures climb across North Shore and Northwest Suburbs, a reliable air conditioning system is not a luxury but a necessity. At R. H. Witt Heating & Sheet Metal, we deliver comprehensive air conditioning service designed to keep your home or business comfortable throughout the hottest months. Founded by Richard H. Witt Jr. in 1966, we are a family owned and operated business located in Glenview, IL, and we have spent decades perfecting our approach to cooling system maintenance, repair, and performance optimization. Our team serves homeowners and businesses in Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL and surrounding communities with the same dedication to excellence that has defined our company since day one.
The Department of Energy estimates that heating and cooling account for nearly half of a typical home’s energy consumption. That means the condition and efficiency of your air conditioning system directly impacts both your comfort and your monthly utility bills. We use state-of-the-art computerized diagnostic equipment to identify issues that other contractors might miss, ensuring your system runs at peak performance and does not waste energy or money.
Our Air Conditioning Service Process
Every air conditioning service call begins with a thorough evaluation. Our technicians do not simply check refrigerant levels and move on. We specialize in designing comfort solutions that address not only your equipment but also analyze if there are any potential problems with the building envelope that could impact your comfort or indoor air quality. This holistic approach sets us apart because a perfectly functioning air conditioner can still underperform if ductwork is leaking, insulation is inadequate, or air sealing issues exist within the structure.
During a standard service visit, our technicians perform a comprehensive inspection that covers every critical component of your cooling system. We examine electrical connections, test capacitors and contactors, measure airflow across the evaporator coil, inspect condensate drainage, clean or replace filters, check thermostat calibration, and evaluate overall system performance against manufacturer specifications. Each step is documented so you have a clear picture of your system’s health and any recommended actions.
Preventive Maintenance That Extends System Life
Industry data consistently shows that regular preventive maintenance can extend the life of an air conditioning system by several years and reduce the likelihood of unexpected breakdowns by up to 95%. We strongly recommend scheduling annual air conditioning service before the cooling season begins. Catching worn components, low refrigerant, or dirty coils early prevents small problems from becoming expensive emergency repairs during the peak of summer heat.
Our preventive maintenance program is built around a detailed checklist that covers every aspect of system operation. As a Carrier Distinguished Dealer recipient, we follow manufacturer guidelines and best practices to ensure your equipment delivers the performance it was designed to provide. This designation reflects our commitment to technical excellence, ongoing training, and customer satisfaction. Our customer satisfaction rating of 99% speaks to the quality of every interaction we have with homeowners across Glenview, Northbrook, Highland Park, Glencoe, Winnetka, and Wilmette, IL and the communities we serve.
Emergency Repair and Diagnostic Services
Air conditioning failures rarely happen at convenient times. That is why we offer 24/7 emergency service to ensure you are never left without cooling when you need it most. Our technicians arrive equipped with advanced diagnostic tools that allow us to quickly pinpoint the source of a problem, whether it involves a failed compressor, a refrigerant leak, a faulty control board, or an electrical issue. Common signs that your system needs immediate attention include:
- Unusual noises such as grinding, squealing, or banging coming from the outdoor or indoor unit
- Warm air blowing from supply registers despite the thermostat being set to cool
- Frequent cycling where the system turns on and off repeatedly without maintaining temperature
- Ice formation on the evaporator coil or refrigerant lines indicating airflow or refrigerant problems
- Unusual odors suggesting mold growth in ductwork or an electrical component overheating
