Weil-McLain AHE Boiler Reviews


1.0 rating
Very Unsatisfied

New Weil-Mclain Ultra installed 17 month ago, and due to a power surge during a storm, it needed a new control board. The cost was $375 which is bad enough, but what do I do during future storms…cut the power to the unit each time? I'm afraid that I am in for repair costs on a reoccurring basis.

Other AHE Reviews

Weil-Mclain has received a range of reviews from around the web. While some homeowners seem to love their unit, others state they’ve had nothing but issues with this boiler.

Reviews on greenoptions.com air grievances from homeowners whose boilers have undergone several rounds of repairs. They state that Weil-Mclain offers poor customer service for needy customers. Bad parts, including the heat exchanger, blower, igniter, and burners, are some of the most frequent causes for complaint.

Despite the negative reviews, other homeowners say their unit has offered reliable performance and “never skips a beat.” Contractors generally recommend this unit, blaming system issues on poor installation. Regular scheduled maintenance, they say, is the key to seamless operation.


The AHE is available in different models which vary in efficiency and capacity.
