Washington Energy Services has been helping homeowners throughout Western Washington save money and live more comfortably since 1957. As one of the largest home improvement companies in the Seattle-Tacoma area, we are able to provide you with top-quality products and services, installed by our professional craftsmen. Our free in-home estimates ensure you get the right product for your home. We'll be with you through all aspects of your project from the purchase decision, expert installation, quality maintenance and service, and even warranty work should you need it. We assist with permits and rebates, too. Give Washington Energy Services a call today to learn more or to schedule your service.

"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!"

We have been serving the Greater Puget Sound area since 1982. Today we serve all of King, Pierce, and Snohomish counties. South West focuses on customer service as the differentiating factor between our company and other plumbing, heating, air, and electric contractors in the area. Our expertise, support staff, and quality work will earn your business for years to come.

"We Had Southwest Plumbing come to our house to attatch a hose bib that my husband wasn’t able to do because of the angle of the piping. He had the crawl space totally accessible and plenty of room to it as well as cob webs etc cleaned out of there. Hose bib was already removed from house. We also had a new hose bib on hand. It took the plumber 7 min to do the job. They quoted 1048.00 and we assumed they would deduct a couple hundred off when the job was done, it could not have been easier for the plumber. Again 7 min job…….. I have reached out to them 3 times to talk to Andrew which I’m sure is a manager. He has NOT returned our call. A call back and parcial refund would make all the difference as the plumber did his job well. With assessing the job they were at our house a total of 50 minutes and it cost over a 1000.00, very unacceptable. We are hoping they will make this right."

We offer quality products at reasonable prices because we want to satisfy your requirements without subjecting you to needless hassles or expenses. We are committed to the values of honesty, integrity, and safety. We are a fully licensed organization, so you will not be taking any needless risks when you engage our services. Plumbing installation service from us will enable you to get a new toilet, sink, water heater, or any other type of plumbing fixture or appliance that you desire.

"Schmitty's Plumbing responded to my Angi's service request almost as soon as I submitted it, and they beat out three other Angi plumbing companies in terms of pricing and transparency. I hired Schmitty's to remove an old double bowl kitchen sink and faucet with a new single bowl sink and upgraded faucet. There was no upselling or attempts to convince us to replace our garbage disposal which two of the other plumbers recommended we do. We saw no reason to replace our disposal which functions well and is not that old. Partners Drake and Gage came out to our home as scheduled, and they got to work immediately working efficiently and thoroughly. We appreciated their no-nonsense, honest, prompt service, and very fair pricing. I chose Schmitty's based on the positive customer reviews, and would hire them again. I told them I would recommend them to all my friends who have plumbing needs!"

"This was by far the absolute worst experience that I have ever had with any company. The plumber came out for a shower that was not draining. I am on septic and let them know that my septic was just pumped in July. However they wanted to check anyways. After checking under the baffle inspection, I was advised by the plumber that my septic tanks were full and needed to be pumped. I contacted a septic company they came out first thing the next morning and checked my septic tanks, they were not full and ironically enough was able to pull out a huge clog of toilet paper from the baffle. He advised this is something that the plumbers do but since we just had one out the day before and they did told us the wrong information he would happily fix the problem for us. My husband called Riley Cahill (the manger) the next day to try to talk to him about the situation and try to find out why we were charged so much since there was not an itemized receipt. Riley proceeded to get very defense and angry and HUNG UP on my husband. He then called back left a message that saying he will check with his plumbers on Monday and get back to us. Monday morning I called Riley Cahill to have a conversation of what went wrong and how we will remedy the situation. He proceeded to once again get very upset, raise his voice and was insanely disrespectful (telling me to be quiet and stop talking). Then hung up on me as well. After that he called back to tell me I was wrong, and hung up on me again. I told him during the conversation that I was going to warn anyone I could not to use this company through reviews, DO NOT USE THIS COMPANY!!!!"

Solar Panels questions, answered by experts

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

Solar panels have a life span between 10 and 40 years, depending on the type of panel. For example, monocrystalline panels can last up to 40 years, while thin-film ones only last between 10 and 20 years. The longevity also comes down to keeping up with solar panel repairs and their related costs .

Yes, a solar panel can power a TV without a battery, but only if the sun is shining and the panel is generating enough energy. Your solar panel and TV must have the same voltage, and you should install a charge controller and inverter between them so power surges don’t destroy your TV. To watch TV at night, in the early morning and late afternoon, and on cloudy days, your home must be tied to the power grid.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

Solar panels can protect your roof from hail, as they can withstand hail up to 1 inch in diameter that falls up to 50 mph. Your solar panels may experience damage if the hailstones are bigger and travel faster. Your roof can still suffer hail damage, and it’s essential to look for signs and repair issues right away. Roof damage can lead to leaks and water damage inside your home.
