Arlington homes, from our experience
Arlington is a dense mix of high-rise and garden condos, older bungalows, colonials, and post-war ramblers on compact lots. Equipment access, association coordination, and tight clearances shape HVAC work here, and the older single-family stock frequently has undersized returns and piecemeal duct additions.
Local notes for Arlington
