Should You Replace Or Repair Your Furnace?

Repairing your home’s heating system will usually be the more cost-effective option, however, if your furnace is old, then replacing your system should be your best bet.

A new furnace system will require fewer maintenance costs and can save you money in the long run. Typically, a furnace should last for around ten to twenty years. If your furnace is within this range, then we consider having a new furnace installed.
