Short answer: it depends on the type of work. Here’s what Houston-area homeowners need to know.
When a permit IS required
- New system installation — replacing an entire AC or furnace system
- Equipment changeouts — swapping an old unit for a new one (even same size)
- Ductwork modifications — adding, rerouting, or significantly modifying ducts
- New construction — any HVAC in a new build or major renovation
When a permit is NOT required
- Routine repairs (capacitor, contactor, fan motor replacement)
- Maintenance and tune-ups
- Thermostat replacement
- Filter changes and minor adjustments
Why permits matter
- Safety — inspections catch dangerous installation errors
- Home value — unpermitted work can cause problems when selling
- Insurance — claims can be denied if work wasn’t permitted
- Warranty — manufacturer warranties may require permitted installation
