They went above and beyond my expectations.

“Outstanding service and price!! It was 112 today when my AC unit crapped out and when a competitor quoted me too high to fix a leaking capillary tube on my AC unit, Leonard and company came out before I even got home from work, fixed it, and saved me $200. Friendly, efficient, and cost saving to boot. I can't say enough about these guys. That's a hellish job getting up there on the roof in this weather, and they went above and beyond my expectations. Thank you!”

    “They came right when they said they would and fixed the leak fast. We had a leak in our bath tub to the ceiling below. Awesome! Great service!”

  • Frederick and Sons were superior on every aspect of my service call!

    “Frederick and Sons were superior on every aspect of my service call (quality, speed, knowledge, professionalism, price). I called them out for some plumbing tasks and was so impressed I had them do A/C work while they were at my house. I would recommend them to anyone who asks and will use them as long as I live in the Valley. ”

  • Frederick and Sons was by far the most professional of the bunch.

    “I had 3 HVAC companies come out to estimate a furnace and duct work replacement and repair to my AC lines. Frederick and Sons was by far the most professional of the bunch. He followed up and was responsive to our needs. The crew was a pleasure to work with. Their estimate was competitive and their service first rate. Final bill contained no surprises, what we paid was what was quoted.”

  • They are the best at what they do.

    “They are the best at what they do, they are right on time, fix the issue and can't even tell that they made a repair. Price was just perfect!”

  • The best in Chandler, AZ.

    “Got our furnace repaired from them. Affordable, professional and able to give me a really good estimate on the other repairs. The best in Chandler, AZ.”
