"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

FAQs for well and pump service projects in Mercer Island, WA
Estimating what size well pump you need is challenging and often inaccurate, but a general rule of thumb is to take the number of fixtures—including water-consuming appliances—in your home and aim for that number in gallons per minute. That calculation method would allow for every fixture in your home to use about one gallon of water per minute. However, it’s best to leave the pump size determination to a professional technician, as they can ensure your pump is providing your home with sufficient water, especially during peak usage hours.
Some states and municipalities restrict well pump repair and replacement to licensed plumbers and technicians, while others don’t have requirements. However, it’s always a good idea to hire a certified plumber to repair or replace well pumps and water pumps. Certified professionals are far more likely to get the job done correctly and prevent future issues, which is especially important for ensuring access to clean water for your home.
It’s possible to fix a broken well pump yourself, but we don’t recommend it. Well pumps are hard to reach and service without the proper equipment, and even if you can reach the pump, it involves working in close proximity to water and electricity, which can be extremely dangerous. Any mistakes made during the repair process could contaminate your water supply or put you and your home at risk. Additionally, some states require that a licensed plumber carry out well pump repair. It’s worth it to hire a professional water pump repair service.
The average cost to repair a well pump is $950, with most well pump repairs ranging between $100 and $2,900. A few factors influence your total repair cost, including the component of your well that needs repair or replacement, the extent of the damage, the accessibility of the pump, and the age and size of your well pump. It might be more cost-effective to replace your well pump if it’s old or has multiple broken components, as the average cost to replace a well pump is $1,800.
Most professional well and water pump technicians will take between two and four hours to replace an above-ground well pump, while a submersible well pump typically takes four to five hours to access and replace. You can also ask your well pump replacement technician how long they expect the process to take, as some jobs take just an hour or two. Keep in mind that you’ll be without access to water during the replacement process, so plan ahead by showering early and stocking up on bottled water for drinking and cooking.
