The Hidden Cost of Keeping Your Old System
In California, most older systems cost $800–$1,000+ per year just in repairs. Higher labor rates ($75–$150/hr), R22 refrigerant costs, and peak-season demand drive costs well above the national average.
Based on 2–3 repairs/year × $300–$600 avg per repair in Southern California, plus $180–$300/yr maintenance plans.
🚨 Replacement Tipping Point
When repair costs hit $1,000+/year consistently — it's time to replace.
Most Antelope Valley homeowners with 12+ year old systems are already past this point.

California Averages & Assumptions. Repair cost estimates, maintenance figures, and energy consumption data are based on publicly available California statewide and Southern California regional averages, including data from the California Energy Commission (CEC), Southern California Edison (SCE) published rate schedules, and general HVAC industry statistics. Individual results will vary based on specific home conditions, usage patterns, local climate, insulation levels, ductwork condition, thermostat settings, and occupancy.
System Performance Factors. The energy savings reflected in this calculator assume that new HVAC systems are professionally installed in accordance with manufacturer specifications, applicable California building codes (Title 24), and industry best practices — including proper duct design and sealing, correct refrigerant charge, appropriate system sizing, and the use of compatible smart thermostats and controls. Actual savings depend on the quality and completeness of installation, not solely on equipment SEER/AFUE ratings.
