"They were very prompt when the referral was placed. They also were able to get someone out within two days of speaking with me. The plumber came out & was honest that it wasn’t a plumbing issue & directed us on who to contact next. He also took a look, & fixed another issue with one of our bathtubs. Would recommend!"

"On 6/1/2022 a technician shows up for a water leak under my home, the tech was friendly, on time, and professional, in appearance. I point out where the leak is, after 30 minutes he says the main pipe is probably plugged which created additional weight, possibly stretching supports and as a result the shower drain pipe had been disconnected. He said he would write up a quote, and I was shocked to find it was for 10k. I refused service but asked for a detailed write up for what needed because I was paying an $89.00 Regular Service Fee (29-89) and another fee, MISC level 1 1 which was $97.00 for god knows what. Here is the write up I received from the technician.(More commentary below) "END TASKS*/ upon arrival customer had leak in crawl space and shower has disconnected the reason this disconnected is due to the weight of the sewer line this line is full of water and when wisher is ran it backs up out of this line causing a leak this line has fallen in ,multiple spots and is sagging in multiple spots this is abs piping. I gave options to repipe both bathrooms and then after run camera to locate septic tank. The reason customer is not backing up into house is because everything comes out this shower drain. I gave customer the options for repipe he did not want to continue with any work there is not a cleanout outside for me to camera this line and cannot locate where line exits home for ability to locate septic tank. Options were provided customer did not want to proceed with any work inspection fee was charged. Repipe and camera locate septic Camera Locate Septic Tank from Clean Out 1x $369.00 2 bath/kitchen/laundry drain only L1 1x $9,552.00 Deposit on Ben Society Agreement 1yr $99.00 Start date: 06/01/2022 Subtotal: $10,020.00 Discount: - $315.00 Tax: TBD $9,705.00 I asked how long this work would take and was told 2-3 days. Simple math tells me I could pay a guy 100$ an hour for 97 hours, or 2 full weeks and then some at that rate. I thought to myself, ok, he does not want to do the work so he priced himself out. I am ok with that, but the business owner should be made aware of what is going on and cut these guys loose because there are plenty of other options out there. I am also shocked at the lack of detail for pricing, for 10k I need know specifically what is being done, on a line by line basis. After all, I paid almost 200 dollars and I would like to think I am owed that much. One last detail, I did call in and spoke to "Angel" who said she would relay my concerns and that someone would be calling me back. I am not holding my breath."

Appliance GrandMasters of Greenville is a Family Owned appliance repair company. Our factory trained service technicians are experts in the repair and maintenance of most major brands of appliances. From first contact to job completion, you can be assured of professional and affordable appliance service and repair. We offer fast, friendly and courteous service. We use only the best products and equipment and maintain a high skilled staff to answer any of your questions. We have built our reputation on our commitment to providing quality service, which has earned us many valuable customers.

"Everything went fine. We just had to wait for the part to come in. The refrigerator needed a new compressor. We made the call for service on 10/28 around noon. The next available service appointment was the next day, which meant we had to buy a small chest freezer in order not to lose all of our food. The part was not available until the following Monday 11/02. The repair was scheduled for the next morning, which meant having gone 6 days without a working refrigerator. They were able to at least keep the freezer side at just under 40degrees, which bought us some time on some of our refrigerated items. I've used this company twice and encountered the same issue both times. Parts had to be ordered, so the repair was not completed until the following week. I would just say that in an emergency, such as a failing refrigerator or washing machine, I would have liked a faster turn around time. I have no problem with the quality or price of the repair, and the appointments are usually within 24hours of the initial call, with repair appointment s usually the day after the parts are received. I just had the misfortune of both of my issues occurring mid to late week, so the weekend extended my service time."

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.
