Why Furnace Maintenance Matters

Regular furnace maintenance isn't just about preventing breakdowns—it's about safety, efficiency, and protecting your investment. A neglected furnace works harder, uses more fuel, and can develop dangerous conditions like carbon monoxide leaks.

The U.S. Department of Energy estimates that proper HVAC maintenance can reduce energy consumption by 15-25%. For an average New Jersey homeowner, that translates to $200-$400 in annual savings.
