Fissco Supply is a Texas-based HVAC wholesale supplier with locations in Dallas, San Antonio, and Houston, serving HVAC contractors, plumbers, and trade professionals with equipment, parts, refrigeration supplies, and tools. As a wholesale operation, Fissco occupies a different position in the HVAC market than service contractors — they're the source contractors go to for parts and equipment, which makes them a useful contact for professionals working in Dallas.

The Dallas location operates Monday through Friday 7 AM to 5 PM with Saturday morning hours until noon, reflecting a schedule aligned with contractors who need to pick up parts before heading to job sites. The product range covers refrigerants, thermostats, HVAC equipment, tools, and supplies from multiple brands, with an online ordering option and a customer service team that reviewers consistently describe as knowledgeable and helpful.

Staff members Abel and Holly are specifically named in reviews for prompt, patient, and knowledgeable counter service — a meaningful differentiator for contractors who need accurate answers quickly when diagnosing a job site problem. Multiple reviewers highlight the organized inventory and fast service as reasons to return. The 4.6 rating across 10 reviews is anchored by strong positive feedback, with one Spanish-language negative review noting a service experience that didn't meet expectations.

For HVAC technicians and contractors working in Dallas who need a local supply house with broad inventory and accessible staff, Fissco Supply's Dallas location offers a practical alternative to large national distributors.
