In cold climate, delaying repairs can make indoor temperatures drop quickly, creating an uncomfortable and doubtlessly dangerous situation.
Strange noises coming from the furnace are another warning sign that should by no means be ignored. While furnaces naturally make some sound during operation, loud banging, screeching, rattling, grinding, or booming noises often point out mechanical trouble. These sounds could also be caused by loose parts, motor issues, airflow restrictions, or delayed ignition. In some cases, a booming sound can signal a gas buildup problem, which makes fast HVAC repair service especially important.
