Near a busy avenue, laminated interior panels and meticulous air sealing cut mid‑frequency traffic noise dramatically. A compact ERV freshened air without opening windows, and a right‑sized heat pump stabilized temperatures. Measured night levels fell by roughly fifteen decibels, and energy use dropped meaningfully. The owners describe hearing birds before buses, and their bedroom now hosts restful mornings rather than early alarms from the street below.
Old steam radiators clanged like cutlery. Technicians balanced the system, added thermostatic valves where appropriate, and introduced panel radiators in select rooms while planning an electric heat‑pump transition. Floors gained a thin acoustic layer during refinishing, easing both stomp and hiss. The apartment now warms like a sunrise rather than a bonfire, with fewer pressure swings, less air stratification, and gentler soundscapes around breakfast and bedtime routines.
