For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.

"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

Our team of experienced HVAC Seattle workers can handle any job, no matter how big or small. Need a new gas furnace to meet your Seattle heating needs? We’ve got you covered. Looking for Bellevue air conditioning? Not a problem. It doesn’t matter if you live in a small apartment that needs a new HEPA filter or a large business with a long list of Seattle or Bellevue heating and air conditioning needs. Just give us a call, and we’ll be happy to help.

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

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!"

Heating and Air Conditioning questions, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Unlike other types of air conditioning, portable units don’t require venting or any other associated parts like hoses. For that reason, they don’t function the same as their counterparts, but will do a similarly good job of cooling down small spaces and won’t require any installation or much maintenance.

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
