Dunkirk Boilers Sold us a bad product and tried to avoid honoring warranty Dunkirk New York

Our Experience with Dunkirk Combo Boiler Failure (March–April 2025):

In March 2025, our Dunkirk combo boiler stopped working.
We contacted Yenason Mechanical (Wilkes-Barre, PA), who originally installed it, to diagnose the issue.
The techs informed us that many customers were experiencing the same problem due to faulty Dunkirk circuit boards, which were on backorder.

One technician shared that his own daughter had been without heat since October 2024, awaiting the same part.

Over a period of five weeks, we had no heat or hot water — during winter — while caring for my elderly mother in our home.

Dunkirk required the techs to return eight separate times, swapping out parts under warranty, guessing at the cause of failure via a Facetime consultation with a Dunkirk tech.

Despite the warranty, each visit required time and labor, ultimately costing thousands of dollars.
Dunkirk maintains a tight inventory with no readily available spare parts, resulting in long delays for customers already dealing with a defective product.

On the eighth visit, it was finally determined a full boiler replacement was needed. Finally! But what about all the thousands of dollars we are out for repair attempts?

Bottom line -- in addition to being without heat for an extremely freezing cold and stressful 5 weeks, we are out thousands of dollars for all the unnecessary failed repair attempts caused by Dunkirk trying to avoid honoring warranty on a fairly new furnace boiler.

Finally they paid for a new boiler but we are out THOUSANDS of dollars for all those failed repairs that were done at Dunkirk's insistence and they are not offering a reimbursement. Shoddy product, shoddy service and an absolute ripoff!
