Do I need a permit for HVAC replacement in San Diego?
Yes — San Diego requires a mechanical permit for HVAC replacement, including like-for-like equipment swaps. Permits typically cost $75–$200 and require a post-installation inspection. A licensed CA HVAC contractor will pull the permit as part of the job. Never accept an offer to skip permits — it voids your homeowners insurance claim and can cause problems when selling your home.
Should I repair or replace my HVAC system in San Diego?
The rule of thumb: if repair cost exceeds 50% of replacement cost ($7200 in San Diego), replace it. Also consider age: if your AC is 15+ years old or furnace 20+ years old, replacement makes more financial sense. New 16 SEER2 systems typically save $200–$600/year in energy vs. a 10-year-old system — often paying back in 5–8 years.
