  • It requires frequent repairs
  • Or it has major problems, like a compressor failure or leaking condenser

Review of Dial One Johnson Plumbing

Jonathan was friendly and professional and he put on booties to not track in mud from outside and i thought that was so sweet of him. He took his time and he was training another nice young man. Thank you again!! That’s why I’m a customer. 😘

Review of Dial One Johnson Plumbing

Called for a weekend AC repair knowing it would be slightly more expensive. The tech came within the hour and got the repair done. Repair cost was very reasonable and repair was done within an hour if him arriving. I generally get concerned with unnecessary repairs, especially with weekend jobs, but not the case with Dial One. Will always use them.


Excellent service and follow-up!




Review of Dial One Johnson Plumbing

James was very knowledgeable and friendly. He replaced my water heater within a short period of time and came back to follow-up on the installation. Also Deborah, in the office, did a great job keeping in contact with me to let me know when James was on his way and following up with me to make sure I was satisfied. Definitely recommended!
