Terrible service and zero accountability. I am keeping this review strictly to the bare facts so the company cannot find a loophole to hide it from the public.
I was still charged $100 just to have my time wasted.

Shauna WalshLocal Guide · 53 reviewsiTotal number of Google reviews Shauna has written across all businesses on Google Maps, not just this one.
We have used Parthenon on multiple occasions. The plumbers are fantastic and knowledgeable. Noah in particular did an amazing job with redoing all the pipes in our house and worked tirelessly to complete it. I only took off a star because we had some issues with the office staff not being able to locate our documents. I have also called multiple times to apply a $50 off coupon I had and they only say that they have escalated the issue, but it has been about 2-3 weeks at this point.
Price assessment: Reasonable price
Response from the owner · 6 days ago
Shauna, thank you for your continued trust and for highlighting our plumbers, especially Noah. We are sorry for the frustration with locating your documents and the delayed coupon application. We will review what happened and have our office follow up promptly. We appreciate your feedback and hope to earn that fifth star.
Griffin Shear3 reviewsiTotal number of Google reviews Griffin has written across all businesses on Google Maps, not just this one.
Paid over $9,000 for a new upstairs AC unit out of pocket and we had our first cold night of the year and I was woken up to our new unit never turning on the heat. Verified that it was on the heat setting and it had said that the heat was on but our house was 62 degrees. Proceeded to call Parthenon to see if they could have someone come out and fix it. I’m very limited for time due to having to work a ton and they told me for them to come out on a Sunday it would be a $200 charge. It’s wrong to charge your customer for a service when they paid for a unit that should have been working and not only that but they should have tested to verify the heater worked when it was installed earlier this summer. I don’t usually like writing poor reviews because I feel that it doesn’t really do anything but i think everyone should know that it’s not right to do that to a customer who has used their services several times and never had a problem.
Edit: I just received a call from the service department and they rectified the situation. I’m very happy with their customer service and was not aware that they used a third party on the weekends and they let me know that they would fix the problem. Big thanks!
