Ductless Mini-Split Installation in Washington: what's different
In Washington, D.C. rowhouses, mini-splits are often the most practical way to add air conditioning. Plaster walls and narrow floor plans make ductwork difficult, and many homes heat with boilers and radiators.
Outdoor units visible from the street in historic districts may need review, so roof or rear placement is common. Condo and co-op owners usually need building approval first.
Ask the installer how line sets will be routed through a rowhouse and how wall penetrations will be sealed. On older brick buildings, careful routing avoids visible damage to the facade. Also check whether your electrical panel has room for a new circuit.

FAQ
Ductless Mini-Split Installation questions
Do I need approval for a mini-split in a D.C. historic district?+
If the outdoor unit is visible from public space, it may need historic preservation review. Rear or roof placement often avoids issues.
What size mini-split do I need for a garage?+
Many 2-car garages need 18,000–24,000 BTU in hot climates because of poor insulation and the garage door. A load calculation, and insulating the door, can reduce that.
