Should You Repair or Replace Your HVAC System?
One of the biggest concerns homeowners have when their HVAC system breaks down is whether to repair or replace it. While repairs can extend the life of your system, there comes a point where replacement is the better investment. Here are some factors to consider:
- Age of the system – If your HVAC unit is more than 10–15 years old and frequently needs repairs, replacing it may be more cost-effective.
- Cost of repairs – If a repair costs more than half the price of a new system, it’s usually a better choice to replace the unit.
- Energy efficiency – Newer HVAC models are significantly more efficient, which can save you money on energy bills.
- Overall performance – If your system struggles to keep your home comfortable despite repairs, upgrading to a newer model might be the best solution.
At DiBacco Plumbing, Heating and Cooling, we’ll always provide honest advice about whether a repair or replacement is right for you. We never push unnecessary services—our goal is to keep your home comfortable in the most efficient way possible.
