HVAC Company in Baltimore, MD
HVAC work in Baltimore runs $150 – $700 for most repairs and $80 – $200 for seasonal tune-ups, with full system replacements ranging $3,500 – $7,500 depending on the home. What drives those numbers isn’t just the equipment, it’s the house itself: roughly 70,000 pre-WWII brick rowhomes with plaster walls, shared party walls, and no existing ductwork create challenges that suburban contractors rarely face. We’re Brandt HVAC, and our Baltimore office dispatches crews who know how to work in 12-foot-wide historic homes without tearing them apart. Call us at (984) 538-9003 when you need a technician who understands the difference between Roland Park and a Fells Point rowhouse.
Why Baltimore Homes Are Different
Baltimore sits in IECC Climate Zone 4A, a mixed-humid zone where Chesapeake Bay moisture pushes summer dew points past 70°F and winter nor’easters can drop temperatures into single digits. That means your system needs correct sizing for both latent load (dehumidification) and low-ambient heating performance, not just a standard load calculation.
The bigger variable is the housing stock. Most Baltimore neighborhoods are dominated by 1880s – 1950s brick rowhomes, 12 – 14 feet wide with plaster-and-lath interiors and original one-pipe steam or gravity-hot-air systems that were never designed for cooling. Retrofitting conventional forced air means solving a geometry problem: where do refrigerant lines or high-velocity tubing go without destroying historic plaster? In Fells Point, Federal Hill, and Hampden, the Commission for Historical and Architectural Preservation (CHAP) adds another layer, restricting visible exterior equipment on street-facing façades. Condensers end up on rooftops, in rear yards, or tucked into interior utility areas.
Larger detached homes in Roland Park and Guilford often run on older hydronic boilers, complicating any conversion to combined heating-and-cooling. A technician who works mostly in suburban Howard or Anne Arundel County might touch a mini-split once a month. In Baltimore, ductless and high-velocity small-duct systems (SpacePak, Unico) are core competencies.
Our Main Baltimore Services
Most calls we get from Baltimore homeowners fall into three categories: cooling repairs in July, heating repairs in January, and preseason maintenance to prevent both. Each service has its own Baltimore page with deeper detail.
AC Repair in Baltimore
AC repair in Baltimore means dealing with systems that are often working too hard against uninsulated brick walls and attic heat gain that suburban homes don’t match. We see a lot of compressor strain and refrigerant issues tied to undersized linesets in retrofit installations. Our technicians carry common capacitors, contactors, and refrigerant to get most AC Repair in Baltimore jobs done in a single visit, with a written price before any work starts and the 365-Day Done Right Promise on every repair.

Furnace Repair in Baltimore
Furnace repair here runs the gamut from failed ignitors in newer forced-air systems to complete burner assembly work on original gravity furnaces still running in rowhouse basements. Winter humidity from the bay also accelerates heat exchanger corrosion in systems that short-cycle against cold masonry. We stock ignitors, flame sensors, and control boards for Furnace Repair in Baltimore, and if we can’t fix it same-day, we’ll tell you exactly why and what the timeline looks like.

AC Maintenance in Baltimore
AC maintenance in Baltimore is about heading off the predictable failures: dirty condensers fighting 90°F dew points, clogged drain lines in humid basements, and blower motors laboring against dust from century-old plaster. Our AC Maintenance in Baltimore tune-up includes a written report of what we found, what we fixed, and what’s coming next, so you’re not surprised mid-July.
