Furnaces: Reliable Heating for Your Home

A dependable heating system is essential for homes in the Northeast. Furnaces remain the most popular choice due to their affordability, compact size, and ability to efficiently heat spaces of all sizes.

How Furnaces Work

Furnaces operate as forced-air systems, drawing in outside air, heating it, and distributing warm air throughout your home via ductwork and vents. They can run on natural gas, electricity, heating oil, or propane, making them a versatile solution for any home. Typically installed in basements, closets, crawlspaces, or attics, a well-maintained furnace can last 15 to 20 years.

Choosing the Right Furnace Size

Selecting the correct furnace size is crucial for efficiency and performance. An oversized unit short cycles and wastes energy, while an undersized unit struggles to meet demand. In New Jersey, it’s recommended that furnaces provide 40 to 50 BTUs per square foot, but factors like insulation, window placement, and home layout also play a role.

Furnace Efficiency Ratings

A furnace’s efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The higher the AFUE rating, the more efficiently the furnace converts fuel into heat. A well-insulated home with properly maintained ductwork will benefit from a high-AFUE furnace, resulting in faster heating and lower energy bills.

Furnace Maintenance & Common Issues

Regular maintenance is essential to ensure safe and efficient operation. Annual tune-ups help identify issues such as carbon monoxide leaks, combustion chamber cracks, and dirt buildup. Additionally, air filters should be cleaned or replaced regularly, and duct cleaning may be necessary to remove allergens and dust.

Signs your furnace may need repair include, but are not limited to:

• Blowing cold air instead of heat
• Uneven heating throughout your home
• Running constantly without shutting off
• Sudden loss of heating
• Rising energy bills
• Unusual noises coming from the system

Ignoring these issues can lead to bigger problems, including fire risks or carbon monoxide exposure.
