Gold Medal Services, LLC, warrants and guarantees to the original purchaser, that should Customer accept and purchase Gold Medal’s recommended repair, such repair shall be free from defect in materials and workmanship under normal use and conditions for as long as the Customer owns the residence in which the recommended repair was provided or until the Unit in which the Covered Repair was performed, if applicable, is replaced.

"Gold Medal really helped out after our sewer line backed up into our basement. The other pros all wanted us to pay for a camera view first for several hundred. Then the actual cleaning of the line was $500 and up depending on the results of the camera. Gold Medal had a fixed price for cleaning out a sewer line. They came and quickly diagnosed the problem and cleaned it out. Our technician Brett was awesome and even put us in touch with DryTech to assist cleaning up the water damage."

"I first submitted my information to this company through their website. I received no response to that. I then called them twice to give my information. Each time I called, they told me I would hear from somebody in two to three days. I didn't receive a reply until I left a negative review. By the time I heard from someone named Ed, I already had another company out to inspect the damage in my home. I told Ed I'd get back to him if it didn't work out with that company. That company didn't get back to me for me to pay them and provide the estimates. I decided to try submitting my information for a project on Yelp. I received interest from one company. That company didn't call when they said they would, so it seemed like it was going to fall through with them. I called back Ed to set up a day and time to come out to visit. I ended up hearing from the company that I found after submitting my project to Yelp, and it seemed like they were going to come through with the estimates I needed. I called Ed back to cancel our appointment because I didn't want him wasting his time coming if this other company was going to provide the estimates. This other company wasn't calling when they said they would, getting back to me days later when I wasn't sure if I was ever going to hear from them again. I decided to call Ed to reschedule another appointment. This time he told me his boss didn't want to be involved with providing estimates if they're going to be used in a lawsuit. He referred me to another company, which didn't respond. After getting the runaround from two other companies, Ed and AW Martin got rid of me by referring me to a company that also didn't want to get involved. If a company has a problem with their estimates being used in a lawsuit, that sends up a red flag for me. It's frustrating, but I'm quickly learning how to deal with contractors. Don't tell them what you intend to use their estimates for. Fortunately, I've found a fifth company that I believe is going to provide the estimates I need. I was honest with them and told them why I needed the estimates, and they're even willing to appear in court to back up those estimates for a fee. In that case, I'm sure I can trust them, and their estimates will help me greatly with my lawsuit."

The price was fair, the workmanship excellent and all his staff professional and courteous. I asked Tony about another window and he suggested I might be able to find someone to repair it rather than paying to replace it. You can’t ask for a more honest businessman! Five stars all around. I highly recommend him!"

FAQs for tankless water heater installation projects in Flemington, NJ

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.
