About Ra-Jac Services

A Texas City service story—and a new way to be useful.

Ra-Jac spent decades helping homes, businesses, and institutions across Galveston County and the Bay Area with air conditioning, heating, and refrigeration. We no longer serve customers directly. This site keeps the practical, educational side of that work available as a courtesy.

Established1966Texas City, Texas

The company

Built on honesty and hard work.

Ra-Jac’s archived company profile described a family-owned and operated business founded on a simple idea: honesty and hard work are the foundation of a successful company. Beginning in 1966, Ra-Jac served the air-conditioning and heating needs of Texas City, Galveston County, and the surrounding Bay Area.

Ra-Jac was woven into the Landriault family’s daily life. Jack led the technical and field side. For 50 years, Neoma looked after the finances and the customer relationships that kept the company close to the people it served. Their children, David and Lori, both worked in the family business when they were young, making Ra-Jac a true family effort.

Over the decades, the work ranged from residential comfort systems to commercial and industrial equipment. The company’s published capabilities included central air conditioning, gas and electric heating, heat pumps, ventilation, commercial freezers, ice machines, chillers, and other refrigeration equipment.

That breadth shaped the way Ra-Jac approached a problem: look at the whole system, explain what is happening, and help the customer make an informed decision.

The partnership behind Ra-Jac

Jack and Neoma Landriault

Ra-Jac was more than a company to the Landriaults—it was part of family life. Jack and Neoma built and sustained it together, and David and Lori both had a hand in the family business when they were young.

Laurence “Jack” Landriault

September 21, 1923 – July 15, 2021

Jack’s working life joined engineering, skilled service, and public responsibility. Born in San Francisco, he served in the United States Navy during World War II. After the war, he pursued industrial engineering at the University of Southern California and later helped construct the Frito-Lay and Sherwin-Williams plants in Dallas.

After he and Neoma established Ra-Jac, Jack worked as a commercial and residential HVAC engineer for more than 50 years. Official Texas City records also document his service on the city’s Board of Air Conditioning and Heating. He spent 20 years in the Texas City Lions Club, supported the Lions Eye Bank of Texas, and received a lifetime Lions membership in the late 1990s.

Neoma Landriault

May 4, 1937 – January 23, 2016

Neoma met Jack while working in Dallas, and they married in 1963. Together they built Ra-Jac Sales and Services while raising David and Lori, and the family made Texas City home in 1966.

For 50 years, Neoma looked after Ra-Jac’s finances and its day-to-day relationships with customers. She helped make the company feel personal—keeping the business side in order and staying connected with generations of people who called on Ra-Jac for help. She also served her community as a charter member of the Lady Lions Club in Texas City.

A short history

From family business to courtesy resource.

These milestones combine family memorial records, official city records, Ra-Jac’s archived company pages, and the company’s direction for this site today.

  1. 1963–1966

    A family business took root

    After marrying in Dallas, Jack and Neoma established Ra-Jac Sales and Services and made Texas City home. Service in the Galveston County area began in 1966. Jack led the technical work, Neoma looked after the finances and customer relationships, and their children, David and Lori, both worked in the business when they were young.

  2. Following decades

    Experience widened

    The company worked across comfort systems, heat pumps, ventilation, indoor-air concerns, controls, and commercial refrigeration equipment.

  3. 2008–2014

    Technical experience served the city

    Texas City records document Jack’s appointments to the municipal Board of Air Conditioning and Heating during two recorded terms.

  4. August 2010

    The original information site launched

    Ra-Jac announced a website with expanded air-conditioning, heating, and refrigeration information, homeowner projects, and an online parts store.

  5. Today

    Direct service has ended

    Ra-Jac no longer accepts service or installation work. The website is being rebuilt as a clearer, safer, more current homeowner knowledge library.

What carries forward

The useful part of a service legacy.

Old sales claims and expired service offers do not belong on today’s site. These principles still do.

01

Explain before asking for a decision

A homeowner should understand the symptom, the evidence, the proposed scope, and the alternatives before authorizing work.

02

Look beyond the failed part

Comfort depends on equipment, airflow, ducts, controls, drainage, humidity, insulation, and the home working together.

03

Put safety and qualifications first

Some observations are appropriate for a homeowner. Electrical, fuel-burning, refrigerant, and internal-equipment work belong with qualified professionals.

04

Leave people better informed

This site does not sell service or collect leads. Its value is helping someone ask better questions and recognize a more complete answer.
