Although we can probably do a lot of things we have found over the years. We figured that we can achieve a higher level of customer satisfaction when we stick to our core values and provide the service that we are best at. That is a Five Star Bathroom Solution Project. We love to stay in our own lane.

"All I wanted was a jetted tub (the same size or larger than what I had) and shower doors, That’s it! Regrettably, I went with Five Star Bath solutions of South Atlanta with Lavezza Zanders as my consultant and manager Monty Johnson. What I received was no shower doors at all, and an oval shaped tub that is narrower than the previous tub, this is obvious with even the naked eye. I did not request a particular shape, and I certainly did not request a smaller size. Who the heck would? There is no documentation that I agreed to the tub that was installed specifically, and the contract only states size to be determined at measure. Again, during consultation the same size tub or larger was agreed to. The company responded by telling me that this tub is actually larger than what I had before and to get the proper sized tub, I would have to pay an additional $3000 over the $7000 I had already agreed to pay, and that I had to sign a new contract. They also ordered the wrong size shower doors, so for that I have nothing but holes in my shower. Ultimately, I did not want to sign another contract; I should have been given the proper sizes to begin with. I was given a tub that is 39 inches at its widest point, but my space is over 48 inches. There was plenty of space to put a wider tub without major construction (walls did not need to be knocked down for a better width), this is obvious from the photos. My emphasis on this fell on deaf ears; Monty and Lavezza kept telling me to spend this additional $3000 to get the tub size that fills the width of my space. I then elicited the help of a friend who also has lifelong contracting experience. My concerns were not being addressed and unfortunately, I felt that having a man speak on my behalf would help. On 3 way was Monty, the contractor, and me. The truth came out at this point. First Monty admitted the obvious, the tub is more narrow and only deeper than the previous tub, not LARGER nor the same size! Monty also admitted with the contractor on the phone, that the size, model, and cost difference to get one tub vs another was never presented to me; I was just arbitrarily given a smaller tub! When I asked that they take the tub back and return my $2000 deposit, initially Monty agreed then he reneged. At the end of the conversation, Monty was on the phone cursing at me and the contractor. No one was cursing at him. I attempted to reach The Five Star Bath Remodel Cooperate offices multiple times and got no callbacks at all. For $2000 I got no shower doors and an uncomfortable creaking tub that I didn’t ask for. I want a full refund."

"I am/was/and always willing to let people/company's make things right but they have not. Unless you want to be hustled, left without hot water, poorly advised and live with total buyers remorse DO NOT CALL F+...see below for details I am still at a loss for words...and am reminded every time we use water in our house that we were taken advantage of.. Everything started out fine but then turned into a rollercoaster ride that ended with our family left stuck with a larger bill and our home plumbing worse than we started..here is how it played out: 1. November 2019 the hot water tank that came with our house died (keep in mind this tank was going for at least 15 years in our dirt crawl space with NO PROBLEMS) and the thermocouple finally gave out from what seems it getting wet..remember 15 years of rain 2. After researching several companies/deals I settled on Cool Air and talking to them before, during'ish, and after was fine. 3. When the plumber came to evaluate the area to ensure what I ordered would work, I specifically asked him if the tank sitting on the dirt would be a problem and if we could raise it off the ground? 4. I was ensured that A) "these new tanks are made to withstand water.." B) due to the ceiling height and requirements to have the flume/gas line a certain way it was not possible and we needed a min 50-gallon tank to be up to code C) eventually the plumber "caved in" and put a dish/pan underneath the tank but said it was completely unnecessary but in the end price was good... the job was done in a quick/efficient manner and no mess left behind ** At this point A+ rating .... 5. Fast fwd 2.5 months..all is good the tank is amazing..I am out of town in DC and my wife calls and says the hot water is out..mind you, we have 3 children under 12 yrs old 6. I call CoolAir from DC and ask if someone can look at the tank as my wife was not able to get the pilot light lit 7. CoolAir kindly sends one of their plumbers out late night to light the tank and review the situation..A+ still 8. The plumber calls me from the crawl space and asks me why I had the tank put on the ground as it SHOULD NEVER BE PUT ON THE DIRT...and that the tank is ruined and can't be fixed and needs to be replaced..needless to say, I was confused..upset..and now my wife and kids in mid-Feb (no snow but cold) are now 4 days without hot water 9. CoolAir's head of sales personally goes onsite the next day and apologizes and agrees with the plumber's assessment and said the tank should have never been installed and directly told me the only option is to go tankless...$2k more than what i paid 10. I asked again ..can I raise the tank..same answer..NO..I must go tankless...but was assured... I will have near-instant hot water and if we are going to remodel this will cover the whole house no problem 11. After 5 days of my family with no hot water and Cool Air being kind enough to offset the cost of the Tankless with what I already paid...(A/A- grade now)..I cave in and give the go-ahead 12. The crew arrives to install the tankless on a Friday..I confirm their arrival and land back to ATL Friday around 4 PM and as I am in the Uber they said they were done and leaving...so I ask my mother-in-law to tip them ..which she did generously 13. I get to the house and now everything goes wrong...not only is my shower COVERED IN MUD..but NO HOT WATER...and OUR SHOWER DOESN'T WORK!! 14. After multiple calls, Cool Air sends a plumber to our house at Friday 7/8PM (same guy that came at night while in DC and the only good person of this whole situation)...After reviewing everything he said that the bad part of tankless heaters is they can negatively impact the water pressure and this should have been taken into account..which it WAS NOT..so after 2.5 hrs a trip to Home Depot we get the main shower working..but little to no hot water 15. Over the course of the next week+ and multiple visits, having to buy new pieces for all showers and new faucet for the kitchen we have semi-hot water...also the only honest plumber there who was cleaning up everyone else's mess asked me one day..." why didn't you just install a "low boy" (a wider but shorter 50-gallon tank that would allow it to be raised) and a sump pump for half the cost of the tankless...can you imagine my face??? when I told him that was never presented to me as an option...he just shook his head 16. Hot Water...Not even near instant...on average (and yes timed), it takes almost 2 minutes for our bathrooms to get hot water...and we live in a 1300 sq ft house mind you! 17. Now if anyone does anything water-related at the same time...the other person gets dribbles!!!...so want to wash your hands while the dishwasher is on...good luck..washing machine...same .18 Icing on the cake....they never came back to put the cover on the outside piece of the tankless heater...my kids have nearly burnt themselves on the exposed piping and believe me if they do or a neighbors kids does litigation is on the horizon 19. I have called multiple times asking for someone to come back and install the cover, fix the issue, switch out for a low boy and sump pump..called and asked for the owner...no one returned my calls..no one followed up...it has been almost 3 months"

"I can’t say enough great things about Casteel for all the services they provide. But, for this post specifically, we moved into a home just over 1 year ago knowing the system was very old (1994) and could have issues sooner rather than later. A recent service visit from Casteel validated that not only was our system old, but operating inefficiently and under capacity. We had a Steve follow up with us later that same day who analyzed our current system and calculated that it was under capacity. The home, when built, did not have a finished basement which, when added later prior to our occupancy, simply tapped into the existing system resulting in doubling the space the initial system was not rated to handle. Steve designed for us a new system sufficient for our needs and at 3 price-point options. We elected to do a complete replacement. Though that option was the most expensive, it was attractively discounted. We still got a great deal, a 10-year warranty, plus 2 years semi-annual service check ups. The installation team arrived on time as scheduled led by Kyle and another Steve, plus several other team members to install our new HVAC and heat pump. They dropped tarps within the interior of our home from used exterior doors to the basement and attic work locations. They did an excellent and professional installation to include upgrading to current code, Re-plumbing all lines, installing new thermostats, and adding a return air vent in the basement which had not been done when the basement was finished.

"I can’t say enough great things about Casteel for all the services they provide. But, for this post specifically, we moved into a home just over 1 year ago knowing the system was very old (1994) and could have issues sooner rather than later. A recent service visit from Casteel validated that not only was our system old, but operating inefficiently and under capacity. We had a Steve follow up with us later that same day who analyzed our current system and calculated that it was under capacity. The home, when built, did not have a finished basement which, when added later prior to our occupancy, simply tapped into the existing system resulting in doubling the space the initial system was not rated to handle. Steve designed for us a new system sufficient for our needs and at 3 price-point options. We elected to do a complete replacement. Though that option was the most expensive, it was attractively discounted. We still got a great deal, a 10-year warranty, plus 2 years semi-annual service check ups. The installation team arrived on time as scheduled led by Kyle and another Steve, plus several other team members to install our new HVAC and heat pump. They dropped tarps within the interior of our home from used exterior doors to the basement and attic work locations. They did an excellent and professional installation to include upgrading to current code, Re-plumbing all lines, installing new thermostats, and adding a return air vent in the basement which had not been done when the basement was finished. They worked long and hard all day long, installation is clean, neat, and professional in appearance, and cleaned up afterwards exceptionally. I commend each and every one of them for a job well done! I highly recommend Casteel for all your heating, air, plumbing, electrical needs. I have used Casteel for all of these services because each and every time Casteel is punctual, professional, friendly, knowledgeable, neat, and highly-competent providing their services.

FAQs for tankless water heater installation projects in Union City, GA

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
