"I called for a service  on March 6, 2015 and the set up the appointment for between 1 and 4 pm, on March 9, 2015.
The called me again on March 9 at 10 am and reset the appointment for 11am and 12pm on March 9, 2015 as their repairman had a opening.  I agreed to the change and waited until 11:30 am and called them and said I had not heard from the repairman.  They assured me that he was on his way..  At about 12:30 the called me and said he could not make it because he had to take someone to rehab appointment, but said they would get someone there between 1pm and4 pm.
At 3:50 pm a guy in a delivery truck came to look at the softener..  He looked at the softener and after 5 - 10 minutes found that the new water I had installed 2 month ago, was sitting on top of the discharge water tubing preventing the softener from operating
Since he did not have a service truck he could not fix the softener.  He offered to send another service truck out the next day, but  I would have to pay another service charge.  I declined and said I would go to the hdwe store and buy and install a new tubing for the softener..
I was told over the phone that the service charge was going to be. $78.00.  What I wasn't told was that there is a$2.00 a minute charge for the time the "serviceman" was at my home for a total o $20.00.  I also was not informed that there would be a FUEL SURCHARGE of $4.96.  After reading this I decided I can not afford to call these people ever again.

"Plumber Mike P. was awesome. He called ahead to let me know when to expect him, he showed up on time, was pleasant, professional and, obviously, a master of his trade. He left the workspace meticulous; you would have never known he was even here. I highly recommend Finken for water heaters and any plumbing work you may require."

"We had an issue with our water conditioning system for Aquarius. They attempted to remedy the problem and determined they needed to replace the system. With the system being over 5 years old, I was uncertain what it would cost me, however, the only thing better than the equipment they provide is their customer service. No cost to replace with a better system. Now that is service!"

"The plumber did a great job but the cost was substantially over our budget. We needed the work done. He said he could do it immediately so we went forward. He had to move our drain and cold water supply. We also expected to give us a 15% rebate because we were first-time customers. That DID NOT HAPPEN. When I called them they said they did not see me in their system--yet they sent me this evaluation. Now that I am in your system -send me 15%."

"Here is the revised version: Today’s Plumbing Service & Repairs did an excellent job fixing my garbage disposal. They were professional, reliable, and easy to work with from start to finish. The communication was clear, the service was prompt, and the repair was completed with care and attention to detail. I appreciate a company that shows up on time, explains the work clearly, and gets the job done right. I would highly recommend Today’s Plumbing Service & Repairs to anyone needing plumbing service or repairs."

"My old water heater was replaced in my small condo utilty room, then we found mold in the wall behind the furnace. The water heater had to come back out to fully mitigate the mold. Today it was reinstalled. The process was smooth. Dustin did the work and was efficient, friendly and professional. I highly recommend O'Boys for any plumbing and heating needs."
