National Service and Maintenance Agreement

The National Service and Maintenance Agreement is an agreement negotiated and administered by the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry (UA) and the Mechanical Service Contractors of America (MSCA) and is a signed contract between the UA and individual mechanical service contracting firms who apply and qualify. The Agreement is a nationally recognized tool that helps contractors provide quality, consistent service to their customers throughout the country and helps reclaim lost market share.

In Part 2 of the Construction Helmet Research Program video series, we take a closer look at the partnership behind the data.

U.S. union membership remained essentially unchanged in 2025, with 10.0 percent of wage and salary workers belonging to a union, according to data released by the Bureau of Labor Statistics (BLS). The total number of union members stood at 14.7 million, well below the 17.7 million recorded in 1983, the first year of comparable data.

Service leaders may lack clear, data‑backed insight into whether their operations, pricing, staffing, and technology choices are competitive—causing missed revenue, weaker margins, and inefficient growth decisions. The MSCA 2025 Benchmark Survey provides valuable insight into key performance indicators (KPIs), business practices, sales, and trends across the mechanical service industry. This is one of the most powerful tools available to see how your company compares, identify growth opportunities, and guide future planning. It’s just one of MCAA’s educational resources that are free to MCAA members as a benefit of membership.

If you want to fast-track your new and aspiring field leaders, MCAA has just the program! Once a week for 8 weeks, FFL students spend 90 minutes online with an experienced field leader, who will walk them through best practices and practical strategies of running work and running a crew. From Planning to Leadership, from Documentation to Safety: our instructors break down the ‘why’ and the ‘how’ of things that every foreman must understand to be successful.

Registration is now open for MCAA’s April Field Leaders Conference, being held Tuesday, April 7 – Thursday, April 9 at the InterContinental Houston, an IHG Hotel in Houston, TX. In two and a half days, your field leaders will hear from inspiring industry speakers and participate in powerful collaboration, leaving them inspired and re-energized. Don’t miss this opportunity to register your field leaders today.

MCAA’s Virtual Trade Show connects our contractor members with the members of MCAA’s Manufacturer/Supplier Council.

At its July 18–19, 2025 meeting, the MCAA Board of Directors reviewed and advanced a series of proposed bylaws changes designed to modernize membership classifications and ensure the long‑term sustainability of Association funding. MCAA members will be voting on these changes at MCAA26.

Pre-IPM is back for another season! This year’s classes will begin April 29th: if you have Assistant Project Managers, Project Engineers, new hires, or people transitioning to the office from the field or Estimating, this online course is for them!

MCAA’s Safety Statistics & Awards program rewards MCAA members’ safety performance, because safety is your top priority. All applicants receive a valuable benchmarking report that will allow them to compare their own 2025 incidence rates with the aggregate rates of the other participating MCAA companies overall, those in the same size category, and with the U.S. Bureau of Labor Statistics incidence rates. Those who qualify also receive a certificate of commendation. Apply today! Applications are due by close of business on March 20, 2026.

As part of its ongoing commitment to protecting your livelihood and setting the stage for a bright future, MCAA has secured the services of Longbow Public Policy Group to advise our MCAA Government Affairs Committee (GAC). GAC Chair, Jim Gaffney will be passing along information relative to our industry on a regular basis.

The John R. Gentille Foundation (JRGF), in partnership with ELECTRI International, The Association of Union Constructors, and American Society of Concrete Contractors, has released the results of a major construction helmet research initiative conducted with the Virginia Tech Helmet Ratings lab.

This report provides a comprehensive overview of MCAA’s 2025 programs, initiatives, and achievements across all subsidiaries and focus areas.

From capacity‑filled conferences and innovative training programs to significant scholarship investments, legislative progress, and collaboration across the mechanical, service, plumbing, safety, and career development sectors, these efforts reflect MCAA’s ongoing commitment to advancing member success and supporting the industry. Together, these highlights illustrate the momentum carrying the organization into 2026 and beyond.
