Donnelly's began serving Montgomery, Bucks, Chester, and Delaware county, PA residents as a premier plumbing company in 1972, later expanding to offer HVAC services. 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.

We understand that home services can sometimes be an unexpected, significant investment and at Donnelly's Plumbing Heating and Cooling we want you to have peace of mind when financing these purchases. That's why Donnelly's offers service financing. To learn more about our financing options, call (215) 799-9763. Ask about our Gold Star Membership program, which can help you save on your scheduled maintenance and even repairs and service.

Tech that came out was super friendly and professional. He also made sure to work with us to give us what we truly needed done instead of up selling us for a larger project. I have always enjoyed the service provided by Donnelly's. This visit involved an estimate for a new gas boiler and I agreed to have it installed next week.

William did the job I scheduled correctly and quickly. Was on time and professional. William/ Donnelly's is the only plumber I will use

Due to construction, we were having some HVAC and plumbing issues. Travis was our assigned technician and he did an excellent job by designing and implementing a solution. He was on time, polite and considerate but most of all he was proficient in his work. His attention to detail resulted in a remedy to the situation and he even made suggestions for improving the system performance. I highly recommend Donnelly's for quality workmanship.

We had an emergency situation with a pipe breaking leading from the sump pumps to the outside during a rapidly melting snowfall and we called Donnelly's on a Saturday afternoon. Their plumber Fred was there in an hour and repaired the situation in 45 minutes at a very reasonable fee and accepted a coupon from their website to defray the costs. We have found a new plumbing company! We are very pleased with this prompt and professional service. Highly recommended! Sharon, Warrington PA
