Get answers to common questions about hvac services in Baltimore, Maryland.
In the Baltimore area, the cost for a full system replacement typically ranges from $5,000 to $12,000+, depending on the system's size (measured in tons for AC, BTU for furnace), efficiency rating (SEER2 for AC, AFUE for furnace), and brand. Baltimore's older row homes with unique ductwork layouts or access challenges can increase labor costs. It's crucial to get multiple detailed estimates that include Maryland's 6% sales tax and any potential rebates from Baltimore Gas and Electric (BGE) for high-efficiency units.
The ideal times are during Baltimore's shoulder seasons—early spring (March-April) before the humid summer hits and early fall (September-October) before winter's chill. Scheduling during these periods ensures your system is ready for extreme weather and provides much greater availability and potential scheduling discounts from local contractors. Avoid calling during the first major heatwave or cold snap, as wait times will be longest and emergency service rates apply.
Yes. Baltimore City and County require HVAC contractors to be licensed and insured. Furthermore, any work involving fuel-burning appliances (like gas furnaces or boilers) must comply with Maryland's specific fuel gas and mechanical codes, and installations often require a permit and inspection from the local building department. Reputable Baltimore-area contractors will handle this process, but homeowners should verify their provider is licensed (you can check via the Maryland DLLR website) and pulling proper permits.
Look for a locally established company with strong, verifiable reviews on platforms like Google and Nextdoor specific to your Baltimore neighborhood. Ensure they are licensed, insured, and offer detailed, written estimates. A trustworthy provider will perform a Manual J load calculation specific to your home's construction (important for Baltimore's varied housing stock from row homes to older colonials) to correctly size your system, not just replace it with the same size unit. Also, check if they are a BGE Trade Ally, which indicates they are qualified to handle utility rebate programs.
This is a common concern in Baltimore's historic and tightly packed housing stock. The issue is often not the HVAC unit itself but the home's envelope and distribution system. Inefficient, leaky, or poorly insulated ductwork (common in basements and crawl spaces), inadequate attic or wall insulation, and old windows are major culprits. A reputable local HVAC technician can perform a duct leakage test and a blower door test to identify air infiltration issues and recommend sealing and insulating solutions before you invest in a larger, more expensive system.
