AC installation cost by system.
Installed pricing for Annapolis, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Annapolis, the cost of AC installation typically ranges from $4,000 to $8,100 for a like-for-like central AC replacement, and $6,100 to $13,200+ if new ductwork is needed. Ductless mini-splits run $3,000–$8,100, while heat pumps range $5,100–$12,100+. The median home in Annapolis was built in 1974, so many homes have older ductwork that may need upgrades or sealing. Maryland requires a mechanical permit for AC installation, and the state's minimum SEER2 is 13.4 for the North region. With the phase-down of R-410A, newer systems use R-454B or R-32 refrigerant. Annapolis has a mixed-humid climate with moderate cooling demand, making dual-fuel heat pumps a strong fit for efficiency and comfort.

What Annapolis code requires
Installing or replacing an HVAC system in Annapolis follows Maryland rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Strong statewide electrification push: EmPOWER Maryland requires a low-cost ($100) home energy audit to unlock the largest heat-pump/electrification rebates, and Maryland building energy code (IECC-based) increasingly favors heat pumps.

AC Installation in Annapolis, explained.
What affects AC installation costs in Annapolis?
Labor rates in Annapolis reflect the local median income of $97,219, and permit fees add to the total. The age of your home (median built 1974) often means older ductwork that may need repairs or replacement, increasing costs. Choosing a heat pump instead of a standard AC can unlock federal tax credits (30% up to $2,000 for qualifying heat pumps) and state EmPOWER Maryland rebates, but requires a low-cost home energy audit. System size, efficiency (higher SEER2 costs more upfront), and the need for load calculations also influence pricing.
Common AC installation issues in Annapolis
Aging ductwork
Many homes built in the 1970s have undersized or leaky ducts that require sealing or replacement, adding $2,000–$5,000 to a full installation.
