Repair vs Replace Intercom System: The Definitive Decision Guide

The Repair vs Replace Decision Framework

Deciding whether to repair or replace your intercom system is one of the most consequential financial decisions you will face as a homeowner. The wrong choice can cost you thousands — repairing something that should be replaced leads to recurring expenses and escalating damage, while replacing something that could be cost-effectively repaired wastes money on premature replacement. This framework gives you a systematic approach to making the right decision.

The three factors that should drive your decision are: the current age relative to expected lifespan, the cost of repair as a percentage of replacement, and the frequency of past repairs. If your intercom system is past 75% of its expected lifespan, repairs would cost more than 30% of full replacement, or you have needed repairs more than twice in the past two years, replacement is almost always the better investment.
