Frequently asked questions
Do I need a permit to replace my system in Durham?
Yes. Equipment replacement is not covered by the small-project exemption; your licensed contractor pulls a mechanical permit and the work is inspected.
Is a heat pump a good choice in Durham?
For most homes, yes. Zone 4A winters are mild enough that a correctly sized heat pump handles heating efficiently, with strips only on the coldest nights, and Energy Saver NC rebates favor heat pumps.
