What Affects AC Installation Cost in Exeter
System type is the main driver: heat pumps cost more upfront but qualify for the 25C tax credit. Ductwork replacement adds $2,000–$4,000. Older homes (median built 1980) may need duct repairs or upgrades. Permits and HERS testing add $500–$1,500. Labor rates reflect Exeter's smaller market (tier 4). Choosing a higher SEER2 unit (14.3+ required) can increase cost but improve efficiency.
