Do I need a permit for HVAC replacement in Nashville?
Yes — Nashville 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 TN 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 Nashville?
The rule of thumb: if repair cost exceeds 50% of replacement cost ($4600 in Nashville), 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.

Yes — Nashville's mild climate is ideal for heat pumps. They provide both heating and cooling, use 30–50% less energy than gas furnaces, and qualify for a $2,000 federal tax credit. Payback is typically 5–7 years.
