Do I need a permit for HVAC replacement in San Antonio?
Yes — San Antonio 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 TX 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 Antonio?
The rule of thumb: if repair cost exceeds 50% of replacement cost ($5000 in San Antonio), 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.
Are heat pumps worth it in San Antonio?
Yes — in San Antonio's hot climate, a heat pump replaces both AC and heating efficiently, and the $2,000 federal tax credit brings cost to ~$8,400. Heat pumps are 200–300% efficient vs. electric resistance heating.
