"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

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.
