About Wittichen Supply Co
Wittichen Supply Co operates in Huntsville, Alabama as a wholesale distributor serving licensed HVAC contractors rather than residential homeowners. The company maintains a 4.4-star rating drawn from 104 customer reviews and functions as a supply hub for air conditioning, heating, and refrigeration equipment, parts, and materials. Technicians and contractors across the Tennessee Valley rely on Wittichen for same-day parts availability and specialized components that other regional suppliers Simply cannot match. The Huntsville location welcomes trade professionals Monday through Friday from 7 AM to 5 PM, with Saturday and Sunday reserved for emergency service calls from established contractor accounts.
Unlike retail HVACupply houses, Wittichen Supply carries an extensive inventory of commercial-grade equipment including First Co air handlers, thru-the-wall units, and Friedrich window air conditioners. Their walk-in facility stocks HVAC parts, sheet metal, flex and insulation, pipe and fittings, and refrigerants in bulk quantities. The company also maintains a clearance section featuring discounted equipment and bundle deals for contractors managing larger installation projects. Colin and additional staff members consistently earn shout-outs for accurate parts identification and efficient order processing, according to contractor reviewers.
Customer testimonials reveal named technicians who go beyond basic wholesale transactions. Ragan Self notes that Colin located a difficult-to-find AC component promptly, describing the staff as knowledgeable and approachable. Lisa Allred of A-Plus Comfort LLC praises the teams unwavering commitment to product availability and technical expertise, emphasizing seamless order processing and timely deliveries that strengthen her companys own customer service. Contractors facing heat wave emergencies or tight project deadlines specifically mention Wittichens willingness to assist with hard-to-source parts.
