Long time customer of ours called in after one of his rental properties had a non working boiler. Our Technician Matthew came out after hours to take a look and diagnose the issue. After going through the laundry list of repairs that were needed including a crack heat exchanger which is a safety issue , our customer knew he had gotten everything he could of out of his 30 plus year old boiler. He knew the best course of action was replacement. We were able to order the boiler first thing in the morning and come back to install it next day.
