Why Maryland prices differ from the national average
The U.S. national average for this system is ~$3,800. Maryland’s midpoint of $3,900 is 3% above the national average. Drivers: local labor rates, permitting complexity, distance from HVAC distributor networks, and climate-related equipment sizing.
How to get the best Maryland price
- Get 3 quotes. Absolutely non-negotiable. Prices for the same brand + capacity vary 20-40% within a metro.
- Ask about rebates. Utility rebates in Maryland can knock ${500}-${2,000} off — installers don’t always volunteer this.
- Compare AHRI certified matches, not just brand names. Efficiency ratings only apply to certified pairings.
- Time it right. HVAC installers give 10-20% discounts in shoulder season (April-May, September-October) when they’re slow.

FAQ
Are these prices with or without tax credits/rebates?
These are gross install costs — before tax credits, before utility rebates. Subtract the 30% federal tax credit (up to $2,000/year) to get your net cost, then subtract any local rebates.
Can I DIY?
Some homeowners install this themselves, but doing so voids most manufacturer warranties and may violate Maryland building code / permitting rules. If you self-install, you also cannot claim the federal tax credit on labor costs.
How long should I get quotes valid for?
Reputable installers hold prices for 30-60 days. Beyond that, equipment costs move with commodities.
