Donnelly's Plumbing, Cooling, Heating & Electric

Donnelly's Plumbing, Cooling, Heating & Electric maintains a 4.8-star average across 5,083 Google reviews for residents of Plymouth Meeting, Pennsylvania. This multi-trade contractor operates from 1 Innovation Drive and handles plumbing, heating, cooling, and electrical work under one roof. Technicians are licensed and insured, providing same-day appointments alongside emergency services for urgent household breakdowns. The business also extends expertise to nearby communities including Conshohocken, West Norriton, and Whitpain Township.

The contractor distinguishes itself through breadth rather than narrow specialization, installing and servicing everything from traditional furnaces and boilers to modern ductless mini-split systems and tankless water heaters. A 100% customer satisfaction guarantee backs all installation and repair work. They handle commercial-grade equipment alongside residential jobs and maintain inventory for common parts, reducing callback delays.

Customer reviews highlight James O'Donnell, who addressed a powder room sink issue for a senior resident in 2025, taking time to explain options and recommendadditional repairs. Several negative reviews cite equipment delivered with cosmetic damage and systems struggling to maintain set temperatures in smaller homes, suggesting buyers should confirm unit sizing matches their square footage before installation.
