When Repair Makes Sense, And When It Might Be Time to Replace

If your furnace is less than 10-15 years old, has minor issues and otherwise works, a repair is often the cost-effective choice. However, if your unit is older, has repeated breakdowns, shows signs of major failure (heat exchanger issues, severe inefficiency), or your energy costs have steeply increased — a replacement may be the smarter long-term decision. When you choose replacement, we install premium models such as Trane and RunTru and back them with our Mariposa Advantage warranty (up to 15 years parts & labour) so you’re covered.

Service Area & Local Expertise
