About Us

About John Cook & Associates

Deep in the heart of Texas, Dallas-based John Cook & Associates provides HVAC solutions all over the great Lone Star State. For almost 40 years, we have gone far and wide to serve residential, commercial and industrial customers. Although we are best known for our specialty in new installations and renovations for school districts, we have a tradition of setting the standard for all areas of service in our industry.

In 1978, founder and U.S. Army veteran Johnnie F. Cook followed his dream to build a company that provided excellence in the air conditioning and heating industry. While Mr. Cook is now semi-retired, JCA is still family-owned and operated with Mr. Cook’s successor and son, Kevin Cook, at the helm. We pride ourselves in doing business the “good ol’ fashioned way”, which for us means relying on integrity, professionalism, competitive pricing, and top-shelf quality in everything we do. We have provided services to thousands of customers and hope we have the honor to meet your HVAC needs. Call today, we’d love to hear how we can help!
