Signs You Need a New Furnace

  • ⚠
    Furnace is 15+ years old — Efficiency drops sharply. Repair costs climb. A new unit pays for itself.
  • ⚠
    Repairs are adding up — Multiple repairs in recent years means replacement is smarter financially.
  • ⚠
    Rising gas bills — Aging furnaces work harder to produce the same heat.
  • ⚠
    Uneven heating — Hot and cold spots throughout your home signal a struggling system.
🛢 Still on Oil Heat? Combine & Save More

If you're replacing an oil furnace, switching to gas at the same time is the smartest financial move. You save on the oil tank removal, get SJG/PSE&G rebates, and lock in lower gas rates forever. Most South Jersey homes run $12K–$15K combined.
