Is It Time to Replace Your Gas Furnace?

If your gas furnace is 15+ years old or showing signs of inefficiency, it may be time for a replacement. Consider upgrading if you notice:

Rising Energy Bills – An old furnace struggles to maintain efficiency.
Frequent Repairs – Constant breakdowns indicate system failure.
Uneven Heating – Cold spots or inconsistent warmth throughout your home.
Strange Noises – Banging, rattling, or grinding sounds signal mechanical issues.
Yellow Pilot Light – A blue flame is normal—a yellow pilot light may indicate carbon monoxide risks.
