When I have an issue with plumbing, the air conditioning equipment they installed, or anything else in my home, it is Joseph Frederick and Sons that I call. Thank you all!”

“I was impressed with John Ratcliffe. He listened attentively to me explaining our situation and offered various possible causes and fixes. All things considered, he assured me that our heater would be repaired that very evening. That was what I, as the customer, wanted to hear. Kudos to John!
Olaf arrived and introduced himself. We discussed the problem. He had been briefed and was prepared. He set to work and repaired the circulation pump and capacitor quickly. He also addressed an issue with two valves, determining that an inner washer on each had loosened. He was tidy. He also listened to what I was saying. Again, this is what I as the customer wanted.
All in all, my experience was excellent. 5 stars all the way!”
