Boiler Service

We Can Diagnose, Install, and Service your System

When it comes time to service, repair, or install your boiler system in your new home, you can count on our expert team at Donnelly Heating & Air Conditioning to help. We offer a variety of top-quality products and our certified technicians can service any make or model. If your boiler has stopped working, we can assess its condition and determine if repair or replacement is necessary.

If installation is necessary, we offer the following new systems:

  • Crown: This product is a high-efficiency, gas-fired, hot-water boiler which has multiple venting options to meet your individual preferences. It may be mounted on the wall if you do not have enough floor space.
  • Weil-McClain: This Weil-McClain gas unit is a high-efficiency, wall-mounted stainless steel heat exchanger intended to offer homeowners a chance to cut fuel usage and increase efficiency levels.
  • Columbia Boilers: The Columbia Emerald Series boiler features hydronic heat and a domestic hot-water system, and it comes backed by a limited, lifetime warranty.

No matter what your concerns are, please don't hesitate to call us at (610) 399-1998 to discuss the services we offer and receive a free estimate!
