Emergency Furnace Repair When You Need It Most

Identifying a Failing Furnace

A furnace that’s blowing cold air, making unusual noises, or not turning on at all could be warning signs of failure. Quick diagnostics are crucial, especially during Norwalk’s wet, icy winters where indoor temperatures can drop sharply overnight.

Common causes we resolve:
