Ernst Heating & Cooling

We provide heating and cooling services in Edwardsville, Hamel, and the Metro East area. Our experience spans decades, and our approach centers on helping heating and cooling systems operate efficiently and at peak performance. We work with furnaces, air conditioners, heat pumps, geothermal systems, high-efficiency systems, and indoor air quality equipment. Our services include installation, replacement, repair, and maintenance.

We use modern diagnostic equipment when working on heating systems, and we handle furnace repairs, maintenance, and installation. Our cooling work includes air-conditioning and heat-pump service, from seasonal tune-ups to high-efficiency system replacements. We also offer geothermal and other high-efficiency system services. For indoor air quality needs, we provide purification, humidity-control, and filtration solutions intended to support cleaner, healthier indoor air.

We offer precision tune-ups for furnaces and air conditioners. During a tune-up, we inspect, adjust, clean, balance, and lubricate the equipment so that it operates according to manufacturer specifications. We also provide an Energy Savings Agreement with two precision tune-ups each year—one for the air conditioner and one for the furnace—along with automatic scheduling, priority scheduling, and discounts on repairs and filters.

We are available for emergency heating and cooling repairs 24 hours a day, 365 days a year. When customers call, we provide access to a live representative who can dispatch a technician. We repair systems whether or not we originally installed them and work with equipment regardless of make or model. Our emergency work may involve thermostat malfunctions, loss of power to an HVAC system, damaged fans, and other problems that prevent heating or cooling equipment from operating properly.
