No one wants to experience the frustration and expense of dealing with a heating or cooling system repair, but all home appliances eventually break. While most issues can be solved by a repair, it’s not always advisable to go this route. If you’re trying to decide between repairing your old unit or replacing it with a new one, this will help you make your decision.
Reasons to Replace
- Repair Costs Are Too High: High repair costs are one of the most common reasons that homeowners choose a replacement. Frequent breakdowns quickly add up, but sometimes even one system failure may be too costly to warrant a repair.
- The Equipment Is Old: The recommended replacement age varies from one manufacturer to the next, but an industry standard is 10 years for cooling systems and 15 years for heating systems.
- Parts Are Unavailable: Occasionally, technicians will run into an issue where parts simply aren’t available for a repair. This may be because the system is older, or it may be another issue, such as high demand. Because cooling and heating are critical systems, most homeowners choose to replace a system rather than wait for part availability.
- Energy Efficiency: If your unit is old and your energy bills are high, it’s obviously time to make a change. However, even newer HVAC systems can be inefficient. If you purchased a low-efficiency air conditioner or furnace a few years ago, you may want to upgrade now to offset high energy costs.
Reasons to Repair
- Your Warranty Covers the Repair: If the repair is covered under your unit’s warranty, it usually makes better sense financially to stick with the system you already have.
- The Repair Costs Are Low: Not all HVAC repairs are expensive. If your repair doesn’t require additional parts or hours of labor, you might find that the cost is worth keeping your current unit.
- Your Unit Still Has Life: If you have a younger unit, you’ve probably got several more years worth of life left before you need to consider replacement.
