The age of your furnace in Cayce, SC, plays a significant role in whether you should repair or replace it. In this guide, we explain why you should replace your furnace if it’s old, if the repair costs are too high, or if there’s a problem with the heat exchanger.

Replace It if It’s Old

You should consider replacing your furnace once it nears the end of its lifespan. Furnaces that are 15-20 years of age tend to have reduced efficiency and parts that start to wear out and breakdown, requiring more frequent repairs. Frequent breakdowns, high energy bills and noisy operation are problems you may experience with an outdated furnace.

Replace It if Repairs Cost Too Much

When the repair costs are less than half the cost of replacement in Cayce, SC, repairing the furnace is usually the better choice. You can get a free estimate on how much it would cost to replace your furnace. Your home’s size and insulation affect what size furnace you need, and this impacts the price.

If your furnace has already reached 75% of its expected lifespan, then you want repair costs to be a bit lower. The rule of thumb is to repair it if the repairs cost less than a third of the replacement cost.

Replace It if There’s a Problem with the Heat Exchanger

A damaged heat exchanger requires a major repair, so you may want to replace the furnace rather than repair it. When the heat exchanger cracks, gases can get inside your living space.

Old age is one of the reasons a heat exchanger can crack. Overheating from lack of maintenance can also damage the heat exchanger. Stay on top of annual maintenance to protect this expensive component of your furnace.

With regular maintenance and timely repairs, your furnace is unlikely to need replacement until it nears the end of its expected lifespan. Contact us at Krantz Kooling and Heating whenever you need furnace repairs or other HVAC services in Cayce, SC.
