Clients say

"A big shout out to Jonathan Grubisa of JG Mechanical (formerly Wolfeboro Oil). He is a super capable and nice technician. We have an oil-fired circulating hot water system in a three-level condo that just wasn't doing the job. Jonathan found that two of the three small pumps that were supposed to be circulating hot water had failed, as had one of our three thermostats. Inside an hour he had the problems diagnosed and fixed. A warm thanks to Jonathan."

"John came through for us again! He solved our low water pressure problem and investigated another! Thank you!"

"Jonathan G. was a very good service technician, knowledgeable, friendly and responsive."
