Is It Time for a New Furnace?
Curious whether your furnace is running on its last leg? Try these few indicators that it's time for a new one:
- Frequent Repairs – Needing repairs more than once per year? A new furnace may pay off in the long term.
- Uneven Heating – Suffering from some rooms being a sauna while others remain chilly? That's an indicator that your system is working hard.
- Odd Noises or Odors – Rattling, banging, or odors such as mildew usually indicate large internal issues.
- Soaring Energy Bills – A worn-out furnace must labor more, which translates to increased utility bills.
- 15+ Years Old – Furnaces typically last between 15-20 years before becoming less efficient.
A new, energy-efficient furnace will heat your home, reduce your energy bills, and provide you with peace of mind during the cold season.
