Jess R.
★★★★★
I cannot say enough good things about my experience with Eli. He was here right at the start time of the time window, worked efficiently, and explained everything he was doing. He went ABOVE and BEYOND and got rid of some extra scraps of metal for me along with my old pipe. HIGHLY recommend both Parthenon and Eli for your plumbing needs!!
Traci B.
★★★★★
Finally, a plumbing company that still believes in fair and honest pricing, and being punctual! Guys, I asked my wonderful tech, Eli, if I could tip him via cash app/venmo/etc after he said expeditiously and neatly capped off my water lines, and he said “oh no ma’am, that’s alright, they pay me enough”. I almost FAINTED. Nowadays you can’t buy an ice cream cone without tipping someone.

★★★★★
Parthenon Plumbing was at our home within just a few hours of calling them. The technician was knowledgeable and professional. While I hated to hear the diagnosis (our 16 year old unit is nearing end-of-life), I’m thankful that Parthenon can install a new unit before the winter weather sets in.
Spencer C.
★★★★★
I use Parthenon for both my plumbing and HVAC needs, they’re top of the line! Fast, knowledgeable, and fair. Great experience every time.
Ned H.
★★★★★
Parthenon is what you want in a local plumbing company. Good communicators, professional and polite staff, excellent work, fair price, and a few suggestions (not high pressure upsales) from technician about opportunities for improvement.
Lindsay B.
★★★★★
Appreciate the consistent communication, timeliness, and transparency of this company. Have had plumbing and HVAC services and both were great...Always respectful, timely, and competent. Highly recommend!
Sydney B.
★★★★★
Cody did a great job on my HVAC cleaning/maintenance! He was personable and took the time to diagnose issues. James also did wonderful job on my plumbing cleaning/maintenance! He was kind and took the time to develop a plan for my house. Very pleased with Parthenon.
Kent M.
★★★★★
We had repeated issues with our kitchen sink leaking from pipes/garbage disposals. Other plumbing companies have gauged us with up-charges on quick fixes and advised us to purchase overpriced garbage disposals. Stan gave us options and advice - he made the decision easy for someone like me who is NOT handy, much less a plumbing professional. I highly recommend Parthenon!
James T.
★★★★★
I contacted them for a clogged kitchen drain a little before 1:00; they called back immediately. A few minutes later they called to say a repairman was on his way--allow 30 minutes to arrive. He was there by 1:30, did the job and was finished with the billing by 2:00. Not an emergency by any means, but awesome response.
George R.
★★★★★
Parthenon delivers best-in-class service. I had an emergency HVAC issue on a day that temperatures were going to be in the teens, and they not only squeezed me in that same day, but found a low-cost resolution to the problem. I’m joining their Partnership Program. As as a REALTOR®, I’m now moving them to the top of my “Preferred Vendors” list.
Zanna M.
★★★★★
If you miss how small towns treat their customers and that’s what you’re looking for in a big city like Nashville, then Parthenon Plumbing are your people! This company took exceptional care of me and made me feel confident in the big decision...

Frequently Asked Questions

What are the benefits of tankless water heater installation in Nashville, TN?

Tankless water heaters deliver hot water on demand so you never run out, even when multiple appliances are running at the same time. They only heat water when needed rather than keeping a full tank warm around the clock, which reduces energy costs over a Nashville billing cycle. They also take up significantly less space than a traditional tank unit, a practical advantage in homes where utility space is limited.

Most installations are completed in four to eight hours. The timeline depends on your existing plumbing and whether any gas line or electrical upgrades are needed. Parthenon’s technicians will walk you through what to expect before the job starts.

Most Nashville homes are good candidates, but the right unit depends on your household’s hot water demand and current plumbing setup. A larger home in Brentwood has different needs than a smaller home in East Nashville or a Midtown condo. Parthenon will assess your situation and recommend the right fit for your usage and budget.

It depends on the unit and whether additional work is needed, such as upgrading a gas line or electrical circuit. Tankless units cost more upfront than traditional heaters but deliver energy savings that make the investment worthwhile over time. Parthenon provides a detailed estimate before any work begins.

Yes. Nashville’s water supply carries moderate mineral content that causes scale buildup inside tankless units over time, reducing efficiency and shortening lifespan. An annual flush and inspection keeps the system running properly. Parthenon Partners members have this included in their maintenance plan.
