TESTIMONIALS

★★★★★

Very thorough, answered all my questions.

Justin Ebner was the technician that came to my house when I had water leaking from the AC unit. He was courteous and took the time to walk me through the issue. He was very thorough, answered all my questions. I felt very comfortable that the issue was appropriately identified and the appropriate corrective action was taken.

★★★★★

Got an estimate in 1 day and install 2 days later. Everything was amazingly smooth and effortless and our new system is fantastic. Love our new thermostats too. We were very pleased, especially right now when people are having so many problems getting supplies and equipment. Already recommended to neighbors.


-Nancy Troske

★★★★★

Professional & Friendly

Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.
