A broken furnace is more than an inconvenience—it is a safety risk during O'Fallon winters. LCM Heating and Cooling provides fast, honest furnace repair to get your home warm again. We handle all furnace types, including gas, electric, and heat pumps. Common issues we fix include ignition failures, thermocouple problems, uneven heating, strange noises, and short cycling.

When you schedule a furnace repair, we arrive on time and perform a complete diagnostic. Our technician checks the heat exchanger for cracks (a potential carbon monoxide hazard), tests the flame sensor, inspects the blower motor, and verifies the gas pressure. After identifying the root cause, we offer a clear repair plan with upfront pricing. Because we are a small local business, we stock common parts on our truck to complete most repairs in a single visit.
