Herman Allen Plumbing, Heating & Cooling

Herman Allen Plumbing, Heating & Cooling dates to 1954, according to its own About page, which says it was for years the primary plumbing service contractor in Mechanicsville. During the second generation of family ownership, Mr. Allen sold the business in 2014 to Bantam's Plumbing Company Inc., a commercial and new-construction plumbing firm. A 2021 Blue Book Who's Who article says Bantam's kept Herman Allen as a wholly owned, separate subsidiary so it could add residential plumbing and HVAC. The state license is still held in the Bantam's name at the same Mongo Way address.

The About page says cooling work was added shortly after the sale, along with a Lennox dealer agreement, and the site now calls the company a Lennox Premier Dealer and a Lennox Centurion Award winner. It reports a staff of over 30 and more than 20 trucks, and says technicians train toward NATE certification and tradesman and master licenses. The Blue Book article reports three NARI Central Virginia Contractor of the Year awards in 2018 and 2019.

For plumbing, the drain cleaning page says every truck carries drain machines, a sewer inspection camera and a pipe locator, and that a jet-and-flush trailer arrived in 2025 for lines a machine can't clear. The same trailer serves restaurants on monthly, quarterly or twice-yearly grease line programs. The plumbing page names the brands it stocks, among them Bradford White, Rinnai and Navien water heaters and Delta, Moen, Kohler and TOTO fixtures, and sends larger commercial build-outs to the Bantam's commercial estimating department.

The company fits Hanover households that want plumbing, heating and cooling from one office, and owners planning a remodel or addition who want help from permit to completion. It is a 30-plus-person company with a commercial parent, not a one-truck operator.
