No matter the brand we can service your appliances. Call us today and let us help you get back to your normal life without any hassle.
"I will update this review if (and that is a huge IF) my washing machine ever gets repaired. It has been almost a month without a washing machine. We have a special needs 12 year old and a toddler. Not having a washing machine is so ho*** ** us. Watson was selected as the repair company for a warranty claim. The technician came out to our house. We (foolishly) assumed that when a technician with a truck full of tools shows up...he is going to like...fix it? But no. He spent 5 minutes there. The only time he physically touched the washing machine was to reach in and spin the drum. "Bearing" he said. He then told is he isn't there to fix it. He was just there to look at it. The funny thing is how literal that was. He just looked. Barely touched. He also told us that the people on the phone often leave it up to him to deliver the bad news (that he is not fixing it that day). So he left and said someone would contact me. Nobody did. Eventually I got an email from UPS that some mystery packages were coming from a random address in Texas. A little googling told me it was appliance parts. Sweet. So I called to ask Watson about it. I was told that they usually don't schedule anything until the parts arrive. But she decided to schedule it anyway. So an appointment was made for 10 days out (Feb 16). I was sad because of how long it is taking, but it was also clear I had zero choice in the matter. So I accepted the date on the 16th at 2pm. Remember the part about me having zero choice? Boy, was I correct! Today they called me and said they have to change the date to Feb 24th because it is a half-day repair and requires two people. How did they not know this when they scheduled the first repair? It just shows disorganization & poor communication. Long story short, if you want your appliances fixed within a reasonable amount of time...I highly recommend against Watson appliance inc."

Five Star Bath Solutions of Minnesota is a full service bathroom remodeler specializing in bath and shower remodeling and installations. We offer leading solutions for bath and shower remodeling, including custom bath-wall systems, new bathtubs or tub to shower conversion, walk-in bathtubs, vanities, flooring and much more. We provide quality bath and shower remodeling at an affordable price.
"Bathroom wet space (tub) remodel with Five Star Baths went smoothly for the most part! The transformation is stunning! The quality of the work is exceptional—everything looks polished and feels durable. Communication was somewhat challenging. It was difficult to find a suitable time to connect and discuss the project in detail within my work hours and the hours they have available. Additionally, the final inspection took longer than expected to schedule. I had to personally reach out to coordinate a time that would work and had the expectation that someone would reach out within the next few weeks after the renovations. While this added some extra steps to the process, once the inspection was arranged, the team was efficient in completing it. Overall, I’m thrilled with the end result and would still recommend their services!"

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.
