JJK & Son Services describes itself on its Better Business Bureau profile as providing heating, air conditioning, refrigeration and sheetmetal services to clients in the Pioneer Valley area. A recent customer said John and his sheet metal technician stayed to finish an A/C replacement on an extremely hot day, and that a minor issue required a return by John the next day. A 2021 reviewer wrote that John came back the same day so they would have heat. A 2020 reviewer wrote that their basement was flooding due to condensation and that they fixed it. A 2021 reviewer wrote that a tech sent to check a heat pump said he was not familiar with the system, that the problem turned out to be the backup heat, and that they waited about 10 days for two fuses to be replaced. That 2021 reviewer said they were not told the cost before the tech was sent and paid only the diagnostic charge, which they called too much. A 2019 reviewer wrote that they called John twice, five days apart, about an annual cleaning and a boiler concern, and he never called back. A 2025 reviewer wrote that the owner talks to everyone with no respect.
John and his sheet metal technician went way out of the norm to finish a tenuous A/C replacement They both stayed to finish the job on a extremely hot day taking no breaks Minor issue required a return by John next day with near 95 degree humid day We are Gratfuly back to a cool house True pro s
the owner jhon, talks to everyone with no respect, be prepared for the worse when calling because he really doesn't know what respect is
I know I will never use this company for anything, just based on their driving. Their driver (in a road rage?) just sits at green lights not moving on a busy afternoon for what? If it wasn’t road rage then the guy might as well be Helen Keller. Green light and plenty of horn honking. Loser.
John was professional, very informative and job done right. Came back same day so we would have heat. Definitely our new HVAC company.
I called them to check my new house heat pump system as it was throwing very cold air during the defrost periods, and the outside unit fan won't stop during the defrost. They sent a tech who clearly said that he is not familiar with the system, and he did not look at the outside unit. he then found out the problem which was the backup heat. Then I waited about 10 days for two fuses to be replaced. They want to charge me too much for replaceing those two fuses. I paid them only the diagnostic chrage which was also too much. Also, they did not inform me the cost before sending the tech so I had no choice, but to pay them. I bought the two fuses online which cost me about 30% of what they asked. And I replaced them myself and save myself money and time. Lesson learned, I should have been looking for better company.
