"From bad to worse. The day after they primed the pump, I went to use the pump & there was no water. The priming had failed. I made several attempts to contact Pruitt via email, Facebook & leaving phone messages. The one time a phone call actually got thru to him, he told me he'd call back in 10 minutes as he was on the road. I'm still waiting for a call back. This is the worse I've been treated by any business . Astonished to see they did not guarantee their work when procedure failed. Sad thing is, up until now, I thought very highly of this business & their professionalism & the owner. But when a company refuses to guarantee their work and refuses to respond to an unsatisfied customer complaint, something has gone terribly wrong with the business and or owner."

"On 5/29/25 Tristin came to my house and gave me a quote on a new shower remodel with a new toilet, and we signed the contract. I thought $12,000 plus was exorbitant, but Tristin assured me that Long Home uses quality materials, excellent craftsmanship, and excellent service. He told me that they will replace all the pipes, and the shower and toilet will have lifetime warranties. So, I agreed and gave him half down and it was scheduled for the 6/27/25 and 6/28/25. Tristian called me on the 6/5/25 and told me that for the shower I choose the half wall that was part of my existing shower would have to be removed, he said otherwise I would have to pay an additional $1,500+, because the shower I agreed to couldn’t be installed otherwise. I told Tristin on 5/29/25 that I did not want the wall removed, but after talking to Tristin on the 5th I relented and said the wall could be removed and ordered another toilet for my other bathroom. The day of the installation came, and one guy came on time and the actual plumber came about 2 hours late around noon. They started working on the demolition and Tristin came around 4pm to move the power socket that was in the wall they removed. He put a rough patch on the wall and installed the outlet without the cover. They removed my cabinet from the wall so they could take down the wall but never replaced it. They worked until 10 pm on Friday. Tristin was supposed to come out on Saturday to finish the patch and put the cover on the outlet. Saturday 6/28/25 the helper arrived at 830 am and the plumber arrived at 1030, at 450 pm the plumber showed me the shower rod they sent with my shower, and it was too short. He told me to call Tristin, I did, and he said OK Tristin never showed up and the two guys finished at 945 pm without putting the cabinet back up. I checked the toilet in the bathroom where the shower was installed, and it kept running after I flushed it, and I put a toilet cleaning tab in the other one and noticed the toilet lid does not fit right. I texted Tristin on Sunday morning telling him about both toilets and he texted me back on that Monday and said he could come at 4pm. I work nights and did not get up until around 5pm and I texted him and told him that I do not usually get up until 6pm during the week when I work and he never messaged me back. I sent Tristin another text on Saturday 7/5/25 telling him to ask him when he could come out and fix the problems I have. I have not heard back as of yet. Long Home charges a premium price and Tristin told me that I would get premium service, he said this is why they charge so much, but the experience I’ve had is anything but premium, I paid $12,000 and I only have one toilet that works correctly even though the lid doesn’t fit properly, I had to buy a shower rod so I could use my shower, since the one I bought from them didn’t fit, which makes no sense because they knew the dimensions of the shower. I had to have a wall removed that I did not really want removed, because they made a mistake when I signed the contract. I have the outlet in my bathroom wired without a cover, my wall is not finished, and my cabinet is still sitting in my bedroom. I do not mind spending the money for something, but I want the product and the service to be worth the price, I paid for professionals, but this is not the problems you are supposed to have with professionals."

FAQs for tankless water heater installation projects in Saint Petersburg, FL
Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.
Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.
You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.
A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.
With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
