Is It Time to Repair or Replace Your HVAC System?
One of the most common questions homeowners face is whether to repair or replace an aging HVAC unit. Consider these factors:
- Age of the System: Furnaces typically last 15–20 years, air conditioners 10–15 years. If your unit is nearing the end of its lifespan, replacement is often the smarter choice.
- Frequency and Cost of Repairs: If repairs are frequent or one repair approaches half the cost of a new system, replacement is more economical. Follow the “$5,000 Rule”: age of unit × repair cost > $5,000 usually means replace.
- Energy Efficiency: New, high-efficiency systems significantly reduce monthly utility bills.
- Performance and Comfort: Inconsistent temperatures, constant running, or loud operation may signal the need for a replacement.
