Furnace Replacement in Maryland
Choosing a new furnace means choosing efficiency (80% or 95%+ AFUE), blower type, and venting. In Reno and Carson City, high-efficiency furnaces usually pay back. In Las Vegas, where heating use is low, many owners choose a heat pump or dual-fuel system instead.

Furnace Replacement in Maryland: what's different
Furnace Replacement across Maryland depends on the climate (IECC climate zones 4–5). Furnaces in mixed climates run for several months, and ice storms or cold snaps put sudden load on them. Annual safety checks on burners, venting and heat exchangers are worthwhile.
In Maryland specifically: oil heat conversions. Homes on oil or propane often compare heat pumps and dual-fuel systems.
Maryland licenses HVACR contractors through the State Board of Heating, Ventilation, Air-Conditioning and Refrigeration Contractors. Ask any contractor for their license number before work starts, and expect a written price for furnace Replacement.
BGE, Pepco, Delmarva Power and Potomac Edison supply electricity in different regions; BGE and Washington Gas supply natural gas in many areas.
