As COVID-19 continues to impact the global community, we at Blue Flame want to update you on the steps we have taken to ensure the safety of our employees and customers, please visit our website at www.blueflamecomfort.com for a detailed statement.

Ask us about tankless water heaters, high-efficiency furnaces, and heat pumps! Our office and standard hours are listed but our dedicated team of background-checked and thoroughly trained technicians are ready and willing to assist you 24 hours a day, 7 days a week for emergency services.

"A tech "Graham" came out for an annual maintenance visit on a reliable 15 year old York Furnace with a 20 year guarantee on the heat exchanger which Blue Flame installed in 2010. He could not explain why he was here, and when I told him "routine annual maintenance" he said, "Let's see what we can find". That was the first sign we had opposite agendas. It went south from there. After lots of loud grinding noises, he supposedly found a shiny jagged gash which he showed me on a scope. I am extremely suspicious he created it himself with a power tool. The end result was the furnace was no longer usable and cost me $8K to have them replace. To add insult to injury that guy ruined my screen door, which won't close anymore. I have ended my 15 year relationship with this company, since I no longer trust them."

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!"

Heating and Air Conditioning questions, answered by experts

AC repairs cost $350 on average, but the total can vary from $100 for a refrigerant recharge to over $3,000 to replace a compressor. The cost will depend on the extent of the repair and what type of AC you have, plus whether your HVAC system is under warranty.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.
