Plumbing services include leak repair, drain cleaning, sewer repair, hydro jetting, fixture installation, water heater installation and repair, garbage disposals, and water softener installation and maintenance.

Regular hours run Monday through Friday, with emergency plumbing service offered. Reviewers describe the staff as honest, reliable, and easy to work with, with quick communication and professional crews. One reviewer described calling five companies advertising round-the-clock service about a leaking pipe on a Saturday night and getting help only from Cities 1. Another reviewer described a near whole-house re-plumb during a kitchen and bath remodel, praising the crew's workmanship. Reviewers mention owner Rich Peterson by name and describe technicians taking care to explain options. The company responds publicly to customer reviews. This is a fit for St. Paul homeowners who want one contractor for both plumbing and HVAC, for example replacing a water heater and furnace in a single project. It suits remodel work needing coordinated plumbing and heating, such as kitchen and bath overhauls. Anyone facing a weekend plumbing failure who needs someone to show up before Monday could use the advertised emergency service.

Nasseff Mechanical Contractors is a mechanical contracting company headquartered in St. Paul, Minnesota, built from a one-man plumbing shop into a full mechanical firm serving residential, commercial, and industrial clients. Its listed offerings include design-and-build mechanical work, HVAC services, and plumbing services. Permit records show the company works mainly on mechanical and HVAC projects, and it holds multiple Minnesota licenses, including high-pressure piping. The company's profile reflects a shop oriented toward project and service work for buildings rather than quick residential calls: customers describe long-standing relationships for plumbing and heating service, with technicians who take time to explain outcomes. Some reviews push back — one customer said a heat pump service did not resolve the problem despite a paid visit, and another disputed a boiler diagnosis — suggesting it pays to get the scope and cost clear up front. This is a fit for property managers, building owners, and businesses in the Twin Cities that need a licensed mechanical contractor for HVAC, plumbing, and mechanical project work, including design-and-build installations and ongoing maintenance. Homeowners with straightforward residential plumbing repairs may find a dedicated residential plumber a simpler match, since Nasseff's profile skews toward larger mechanical and commercial work. For organizations comparing mechanical contractors, the company's license credentials and project record are worth verifying directly.
