What People Are Saying

  • Always Something More to Learn

    Education

    “ACCA St. Louis [Gateway] provides contractors with both technical and business training to help them become better business people and to keep their employees educated on the newest technologies. ”

    Ken Perotta, Director of Sales & Marketing, Crescent Parts & Equipment

  • You Can’t Be Everywhere All The Time

    Licensing

    “In this industry, and especially in the St. Louis area, obtaining the proper licenses is crucial to operating an HVAC business. Licensing requirements and code restrictions differ in St. Louis City, St. Louis County, St. Charles County, and Jefferson County. In St. Louis county alone, there are over 100 different municipalities with differing requirements! The ACCA-St. Louis chapter [Gateway] works diligently to keep abreast of these requirements. They keep their member contractors informed, and they have forged relationships with community leaders to promote fair competition in the marketplace.”

    – Mike Schumacher, Vice President, Reliable Heating & Cooling, Inc.

  • Growing the Industry

    Apprenticeship

    “ACCA’s [Gateway’s] apprenticeship program has been a great asset for our company in that it set higher goals for our technicians to meet with technical standards and field experience requirements as well as offering them a career opportunity and not just a job. The benefits to our customers is that we have highly motivated and well trained technicians that take their work standards to the highest level of excellence.  We are proud to be a part of this program. Thanks to all contractors and ACCA for making this possible.”

    Chris Kunst, Westport Heating & Cooling

  • Get What You Need To Get To Work

    PEU Expertise

    “If it weren’t for the ACCA [Gateway], many contractors would be out of business considering the few choices to get PEU’s and the ridiculous complexity of the rules and tracking of the PEU credits.  The PEU Universities arranged by the ACCA  [Gateway] every so many months is a huge help to us. ”

    David Harster, Owner, Harster Heating & Air Conditioning Co.

  • Get Off the Sidelines & Into the Game

    Government Relations

    “If it weren’t for the help we receive from ACCA-St. Louis [Gateway], we could never keep up with the regulations and requirements of operating a business in our current climate.  Most small businesses don’t have the manpower or expertise to deal with government bureaucracies.”

    – Brian Agers, Owner, Agers Heating & Air Conditioning

  • Proud to Support Our Troops

    Community Outreach

    “As an organization, ACCA [Gateway] is proud to give back to our community by contributing through the Adopt A Soldier program.  As an employer to veterans, I know how difficult it is for soldiers to be away from home and how much they enjoy receiving notes, cards and goodies. Words cannot express my gratitude for their service and dedication.  Hopefully by this small act of kindness as we send them “care packages” through the Adopt a Soldier program, that they know how much they are appreciated. The “thank you” notes we receive back show it is a worthwhile program!”

    Patty Clisham, President, DUCTZ of West St. Louis
