What Our Customers Are Saying
"Our boiler went out in the middle of January. Legacy NYC Mechanical had a technician at our apartment building in Brooklyn within two hours. Absolute lifesavers."
"Steam radiators in our Manhattan co-op hadn't been working properly for months. These guys diagnosed the steam trap issue immediately and fixed it the same day."
"Hot water heater was leaking badly. Called at 8pm and they came out that night. Fair pricing and very professional. Won't use anyone else."
