How much should this gap actually matter?
A 0% difference on heat pump installation is minor — you'll typically see a wider spread just from getting multiple quotes in the same city, so don't let location drive the decision.
Heat pump installation by type: Annapolis vs Gaithersburg
Every heat pump installation type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | Annapolis | Gaithersburg |
|---|---|---|
| Air-source (ducted) | $8,300–$12,050 | $8,200–$11,950 |

Heat pump installation by home size: Annapolis vs Gaithersburg
Heat pumps are sized in tons like AC (roughly one ton per 500–600 sq ft), but cold-climate models may be sized up for heating. Ductless mini-splits are priced per zone instead.
| Size | Annapolis | Gaithersburg |
|---|---|---|
| 1,000 sq ft (≈2 tons / 1–2 zones) | $5,600–$9,900 | $5,550–$9,800 |

What hvac pros earn in each metro
Labor is about 60% of a heat pump installation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for heat pump installation in either city
A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
How much should you really budget for HVAC in 2026?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
The efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
