How long does a furnace project take in Maryland?

Like-for-like gas furnace swap: 1 day. Oil-to-gas conversion: 2–3 days (line install + tank removal). Oil-to-heat-pump conversion: 3–5 days (electrical service upgrade often required).

Maryland permit-review timelines and contractor availability can add 1–2 weeks during peak season (spring and early summer). Booking in late fall or winter often shortens the schedule.

What drives furnace pricing in Maryland

The three structural factors that make Maryland more expensive than the national average for renovation projects in 2026.

DC-metro labor rates

Montgomery, Prince George's, and Howard counties share the DC trade labor market. Rates run 25–40% above national. Eastern Shore and Western Maryland trend closer to baseline.

Historic district permits

Baltimore City, Annapolis, and several other municipalities have active historic preservation districts. Window, siding, and roofing work in these zones requires HPC approval — 4–12 weeks of additional review.

Stormwater management requirements

Chesapeake Bay watershed regulations require stormwater mitigation for many projects, adding $1,500–$5,000 in impervious-surface offset costs.
