A O Dowd Plumbing Inc. did an amazing job with the water heaters I needed repaired. The team was friendly and professional all around. They communicated well from beginning to end - even followed up to make sure everything was working well
I had some issues with my boiler and their website was very clear on their expertise in that boiler so I called right away. They were were a little outside my area so Jason spent 15-20 minutes over the phone walking me though how to diagnose and fix it myself. I was able to get it up and running.
