"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Drew came out and did an excellent job diagnosing my clogged bathtub drain. He was on time, efficient, very descriptive in his repair, left left the job totally cleaned up. And it needs to be stated that his price was very reasonable. I’m so happy that I have now found my new go to plumber. I highly recommended Service Flow to my family, friends and to you."

"We had already called another plumber on Angies List (Hayes Plumbing) to have ours replaced. But when he arrived he stated he no longer gave the senior discount as he priced his units so low and he charges more for labor for units INSIDE the home, etc.  So I called Right Solutions Plumbing out of the phonebook and told him of our desperation. He has a good steady business and after hearing of our situation said he would be over that afternoon to look at  our unit and see how soon he could help us. He was the owner - James Ratliff - and he was so kind and professional over the phone.  HE estimated our job and went to get our 50 gallon BridgeWhite (or something like that--- a very good model they dont even sell retail at Lowes or Home Depot).  He came with his assistant, Jerome (really nice young man) and completed the job without any hangups.  By the way, he doesnt charge more for the unit being inside and said he never heard of that policy .  I commend his professionalism and concern for our situation.  He is such a nice guy and well represents his trade. I will use him anytime I need his services.  My husband also was very impressed with James.  He was very knowledgeable and a good communicator which nowadays, just  doesnt happen.
He also has 24 hr emergency service and responds to all his calls. I give him my highest recommendation.  He doesnt low bid and then hit you with all the extras. Very ethical and good to know someone like him has a local business we can depend upon.
