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!"

Dvac Heating & Air LLC, we can offer the best services and prices. Establish business since 2014, we offer residential maintenance plans, install ductless heat pumps, furnaces, central air heat pumps, electrical services, panels, lights, outlets, hot tubs, and other. Give us a call for your HVAC and electrical needs today.

"Avoid working with DVAC at all costs. When I initially requested a quote for the installation, I specifically asked for a 3-ton high-efficiency heat pump. Unfortunately, the experience with DVAC has been nothing short of frustrating. They began by stating that extensive work needed to be done, charging for it all upfront. However, when it came time to install, they drastically lowered the quality of the equipment, gaslighted me, and lied about what was being provided. Hidden charges surfaced right after my existing system was removed. The issues I discovered included but not limited to: 1.The installed heat pump is only 2-ton heat pump instead of the required 3-ton heat pump stated in the estimate. 2.The furnace provided is of lower quality than what was agreed upon. 3.The ducts installed are too small for the system. 4.The electrical cable used may be undersized for 3-ton heat pump. 5. All works were unpermitted. Throughout the project, I repeatedly verified the permit status with DVAC, including on the installation day (8/15). They assured me everything was in order. However, on 8/20, I confirmed with the City of Kirkland that none of the work had been permitted—a clear violation of both city regulations and our contract. Given these serious issues, I requested a full refund and the removal of all unpermitted work. DVAC refused to comply with the contract and denied the refund. If there were a zero-star option, I wouldn't even give them a single star."

Energy Efficiency Auditing questions, answered by experts

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
