Winsupply of Shelton HVAC and Plumbing Supplier

Winsupply of Shelton has roots that date all the way back to 1891. The D.H. Kelly Company of Derby, Connecticut was a successful mechanical contracting firm. The D.H. Kelly Company was acquired in 1971 by N.O. Nelson Company (now Winholesale). The company had operated as Derby N.O. Nelson Company until 1980 when the name was changed to Derby Winsupply Co. The company operated out of a 5600 square foot facility at 38 Commerce St. in Derby.

Henry Panza was named president in 1975 and successfully ran the company until January 1, 1994. Derby Winsupply Company moved to 740 River Rd. in Shelton, CT in November of 1979. It was the growth of the company’s sales which required the larger space that prompted the move. The River Road facility of 20,000 square feet was a boom to company growth. In 1980 Shelton Winair Company was opened in 5000sq. ft. of the existing building. This was the first company sponsored by Derby Winsupply Co. A few years later Shelton Winair was able to move to its current location in front of Derby Winsupply.

Winsupply of Shelton commenced business on January 1, 1994. We are centrally located at 14 Forest Parkway in Shelton, CT in a 64,000 S.F warehouse. In addition to our onsite space, we also have over 850,000 SQ FT of warehouse space through our distribution centers at our disposal. This helps us deliver the products our customers needs in a timely manner and at a competitive price.
