- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
CA Title 24 requires HERS-verified duct leakage testing and Manual J sizing on most AC/furnace changeouts

AC Installation in Lemon Grove, explained.
What Affects AC Installation Cost in Lemon Grove?
Lemon Grove's older housing stock (median built 1967) often requires ductwork modifications or replacement, increasing labor and material costs. System choice matters: heat pumps generally cost more upfront than standard central AC but qualify for larger rebates. Permit fees and required HERS duct leakage testing add $300–$800. Accessibility (attic vs. crawlspace) and the need for electrical panel upgrades can also raise the price. Choosing a higher-efficiency unit (e.g., 16+ SEER2) may lower long-term energy bills but increases initial investment.
Common AC Installation Issues in Lemon Grove
Aging Ductwork
Many homes built in the 1960s have undersized or leaky ducts that fail modern Manual J airflow requirements, often needing replacement or sealing.
Permit & Code Compliance
California requires a mechanical permit, Manual J load calculation, and HERS duct leakage testing; skipping these can lead to fines or failed inspections.
Refrigerant Transition
R-410A is being phased out; new systems use R-454B or R-32. Homeowners must ensure their installer uses approved refrigerants and disposes of old refrigerant properly.
