About Us

Donnelly’s began serving Montgomery, Bucks, Chester, and Delaware county residents as a premier plumbing company in 1972, later expanding to offer HVAC service as well. As the area’s leading plumbing, heating, cooling, and drain cleaning service, we guarantee:

Comprehensive Services
Donnelly’s is your one-stop shop for your home service, installation, and repair needs. We are proud to offer a full complement of services including:

Highly-Trained Technicians
To supply you with the best value and quality possible, we provide ongoing training and education for all our plumbing and HVAC service technicians. Our employees engage in NATE Certification training, manufacturer training programs for new products (i.e., heating and cooling systems, water purifiers, plumbing equipment, etc.), customer service programs, and safety training.

Ethical Conduct
The Nexstar code of ethics governs every aspect of our business, from how we serve our customers to how we treat our employees to how we protect our environment. Ethics isn’t a matter of philosophy to us: it is how we live and work, day by day.

Professional Accountability
Donnelly’s is proud to be a member in good standing of the National Association of Plumbing, Heating and Cooling Contractors; The Nexstar Network; and the Better Business Bureau.

“We have used Donnelly’s for more than 25 years
and recommend you to friends. The service is always great!”
– Dennis P., Lansdale, PA
