Genie Bath Systems provides homeowners with custom bath remodeling solutions, to include a full-line accessibility needs. All of our products are custom made in the USA. Factory Certified Installation.Lifetime Warranty.100% Financing . PLEASE NOTE: WE DON"T PERFORM KITCHEN REMODELS

"Last October, my sister, an elderly veteran living alone, contracted Genie Bath Systems to remodel her master and guest baths. She was diagnosed cancer and passed before the remodel was complete. Which, to be fair as we were not able to work with Genie while attending to my sister. The contract was expensive. Very expensive. The cost of the remodel is close to 1/4th the value of her home. I noticed there were issues with the remodel that showed a surprising lack of attention to detail. Genie sent people to address the issues twice. Yet issues remain. My calls to my contact at Genie are now being ignored. Also, the only document I have for the remodel is the contract my sister signed. It is not detailed. I have and continue to ask for a breakdown of the cost. An estimate or work order. This request is also being ignored. I am disappointed and have to wonder why Genie will not provide this information. I have several other questions for Genie that I will not go into here. But based on my experience, I cannot recommend Genie. In fact I would warn anyone considering Genie to be very careful about the cost of the contract."

"This experience has been a nightmare of frustration. Gilbert from G&I Appliance Repair contacted me on 4/20 about repairing our refrigerator. I explained to him the refrigerator is slightly cool but not cold enough, and the freezer just cold enough to keep ice from fully melting, but will not freeze anything solid. He advised it was a compressor problem without going to my home to do a diagnostic look over. I told him I had tested the fans and the compressor, and they were working. The problem was they were not blowing cold. He insisted it was a compressor problem, and advised me he was an expert and to trust him. He came to my home on 5/1 and replaced the compressor, said it was fixed but it would take a few hours to cool. He charged me $603 and left. I messaged him that same night and told him the refrigerator was still not working. He came back the next day and worked on it, told me it was now working but to wait another 24 hours for it to start cooling again. I once again brought up the fact that the old compressor was working fine and it appears he fixed something that was not broken, and the actual problem is something besides the compressor. He assured me it was the compressor, that he had fixed it and it was now working. On 5/2 the refrigerator was still not cooling effectively and was functioning exactly as it had been when I initially requested a repair. The freezer would not freeze all the way and refrigerator would hardly cool. I called Gilbert and told him neither the freezer or fridge were cold enough, and he asked if I had used a thermometer to gauge the temperature. When I told him “no,” he questioned how I could possibly know it was not cold enough. The curdled milk and fruit flies flying around it are a strong signal that it isn’t cold. Even still, I don’t need to know exactly how much someone weighs to tell of if they are fat. Gilbert offered to come back out and diagnose the problem, but I had already paid $603 dollars for a needless compressor repair. Gilbert now thinks the actual problem might be with the 3-way valve, but he is not certain and he wanted to come back to my house. I asked him why he replaced a fully-functioning compressor if the problem was elsewhere, for which he cannot provide an answer. I told him I wanted a refund, and even went so far as to pay him for a diagnostic fee, which is generous considering he never came out to diagnose the problem in the first place, and he still does not know why it is not cooling. Gilbert suggested I was trying to scam him and was lying about the refrigerator not working just so I could get a refund. He refuses to refund me. I’ve used Angi for several repair needs, and this is the first one with whom I’ve had a bad experience. It’s been awful to say the least. Pathetic, to say the most."

Tankless water heater installations FAQs

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.
