HVAC Services in St. Louis | C & G Heating & Cooling Since 1987

We offer complete heating and cooling solutions including HVAC installation or replacement, system repair, and maintenance services. Our team handles everything from furnaces and boilers to ductless air systems and Energy Star rated equipment. With over 25 years of average technician experience, we serve both residential and commercial clients throughout the Greater St. Louis area, providing emergency services and specializing in geothermal systems and indoor air quality improvements.

For clogged air filters—a frequent issue in our area due to seasonal pollen and dust—we recommend and perform regular maintenance to prevent reduced airflow and system strain. For evaporator coil freeze-ups, often caused by dirty coils or refrigerant issues, our experienced technicians diagnose the root cause through thorough inspection. We clean coils properly, check refrigerant levels, and ensure proper airflow to prevent recurrence, helping St. Louis residents maintain efficient systems year-round.
