I am a "Parthenon Partner" which means I get two HVAC tuneups each year as well as a plumbing checkup. Both of those services were performed today. I value punctuality, and the HVAC tech and the plumbing tech were able to arrive earlier than their scheduled window. Both of the young men were polite and professional. They gave me a verbal report before leaving, and will send me a report on anything that needs to be watched. The big thing to me is they do NOT recommend anything unless it is critical and they will show you why it needs attention. I highly recommend Parthenon for your plumbing and HVAC service.

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.

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.

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.

★★★★★
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!

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.

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.

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...

AC went out at our house this afternoon. Called Parthenon and they were out within a couple of hours even tho we had never done business with them before. They were courteous, informative and got us squared away in no time. Didn’t try to to sell us anything but gave great advice. We’ll be using them the next time we need anything for AC and probably plumbing too. Super impressed.

Warning Signs You Need HVAC Replacement in Nashville, TN

Your system usually gives you a few hints before it completely gives out. Watch for these common signs.

  • The system is over 10 to 15 years old
  • Repair calls keep piling up
  • Energy bills keep climbing
  • Uneven temperatures between rooms
  • Home feels damp or muggy
  • Strange noises or burning smells
  • Frequent short cycling
  • Uses outdated R-22 refrigerant

If you’re noticing more than one of these, it may be time to talk with us about HVAC replacement in Nashville, TN. We’ll give you an honest look at whether a repair still makes sense or if a new system is the smarter move.

Why a New HVAC Installation Pays Off for Nashville Homes

A new system can make a real difference in how your home feels day to day. Modern equipment heats and cools more evenly, so you’re not stuck with a cold bedroom and a hot living room. Many newer systems also run more quietly than older units, which is something most homeowners notice right away.

Efficiency is another big reason people upgrade. Older systems often work harder and longer to reach the temperature you set, and that shows up on your monthly bill. A properly sized, newer system can use less energy to do the same job, especially during Nashville’s hottest months when your AC runs for hours at a time.

Humidity control matters a lot here, too. Nashville summers bring heavy, humid air that can make your home feel warmer than the thermostat says. A new system that’s sized correctly pulls more moisture out of the air, helping prevent that clammy feeling and reducing the chances of mold and musty odors.

You’ll also get fewer surprise breakdowns. Replacing a worn-out system means less worry about your AC quitting in the middle of a July heat wave or your heat going out on a freezing January night. Plus, new equipment typically comes with a manufacturer’s warranty for added protection.

How to Pick the Best HVAC System for Your Nashville Home

Choosing the right system starts with getting the size right. A unit that’s too big will turn on and off too often and won’t remove enough humidity. A unit that’s too small will run constantly and still struggle to keep you comfortable. We look at your home’s square footage, insulation, windows, and layout to figure out what will actually work.

Next, consider the type of system that best fits your needs. Heat pumps are a popular choice in Middle Tennessee because our winters are usually mild, and they handle both heating and cooling in one system. Some homeowners prefer a gas furnace paired with an AC unit for strong heat during colder stretches. Dual fuel systems combine a heat pump with a furnace to give you the best of both.

Efficiency ratings are worth a look as well. Higher-rated equipment costs more upfront but can save you money over time on energy bills. We’ll walk you through your options and explain the trade-offs in plain language so you can make the choice that fits your budget.

Don’t forget about indoor air quality. Nashville is known for high pollen counts in the spring and fall, which can be tough on allergy sufferers. Adding air filtration, purifiers, or a whole-home dehumidifier during installation is an easy way to improve the air your family breathes.
