Abacus Plumbing, Air Conditioning & Electrical Reviews

"The technician was great. Very professional and knowledgeable. Great job!"


“I had a faucet outside leaking and another company said it was going to be very difficult to fix, had to tear wall apart etc. The technician came on a Sunday, repaired the leak, left the faucet better than original and was very good explaining everything. No tearing walls apart etc. Will call them next time I have an issue and request same plumber, he was fabulous.”


“Service tech was knowledgeable and worked rapidly to complete the job over a two day period.”


“Great service from start to finish.”

Mr. R.A.

“Outstanding plumbing service, extremely professional, Randy is an outstanding master plumber. He always exceeds our expectations. Abacus is a trusted and reliable plumbing service provider. We will use this company again and we highly recommend it to our friends. Top Notch company, keep up the excellent job!”

Ms. C.R.

“Abacus did a great job with in my house. I have used many other plumbers over the years, but nothing like these folks. They had a scheduling team calling ahead and letting me know exactly when they would be there. The plumber showed up and properly diagnosed the problems and then handled them. One great part of the service is that all of the parts are on the truck, so no need to reschedule another time to come out and perform the service because they needed parts. The prices were fair and easy to understand and the whole process lasted just a couple of hours. I couldn't be more satisfied and I will be calling Abacus in the future for all of my needs.”

Mr. M.D.
