Regular maintenance is crucial for heat pumps to ensure they function correctly in both seasons.

What should I do if my furnace stops working in winter?

If your furnace stops working in winter in St. Louis, it's considered an emergency. First, check your thermostat to ensure it's set correctly and the power is on. Check your circuit breaker.
