"Our realtor recommended Para home services when we bought our house, so we tried them out. Our team, Zoe and Matt were great, they listened to all my ramblings and half baked suspicions about what things were wrong with the house and set to work. On top of a thorough maintenance pass -cleaning dryer vents and refrigerator compressors, they also addressed a random list of things like a loose sink, and faulty bath faucet, a couple of dead outlets and misbehaving light switches but also troublshot our mysterious radiant floor system, got it all working and explained how it was set up. I learnt a lot about the house and ultimately have a greater peace of mind. I will be signing up for a membership."

There are so many options for keeping your home comfortable. Lifetime Heating & Air Conditioning is the "only" HVAC business in Washington that offers a Lifetime Warranty on your equipment while enrolled in our maintenance program. That means, no more diagnostic calls, after hour fees, upselling, or technicians who "always" find something wrong on your equipment. Our heating and cooling technicians carry the highest level of certifications including WA L&I Electrical licenses, NATE certifications, EPA certifications and are licensed, bonded and insured. Employees are background checked, drug tested and comply with safety and driving requirements. We are specialists in furnace, air conditioner, heat pump, indoor air quality, and weatherization service, repair and installation. We can service gas fireplaces, humidifiers, generators, tankless and standard water heaters and more! We guarantee your comfort for a LIFETIME!

"Wow, these people were great! After seeing another company struggle to get two very old fas fireplaces to work, our property manager was directed by another fireplace repair place (who no longer services gas fireplaces) to call Lifetime. They sent Travis McKibben to our home, and he was fast, efficient, and most of all, he got the job done and done well. He really knows what he's doing, and is a really nice guy too. If you have to get service on a gas fireplace (especially an older model), or need HVAC work, I highly recommend this company and this technician."

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. Blue Flame Comfort specializes in residential install, service as well as maintenance with a 100% satisfaction guarantee. 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."

We at Allred Heating, Cooling and Electrical hope to become your trusted friends and partners in keeping your homes safe, comfortable, and a pleasant environment for you and your families. How Allred Got Started Our company was founded by Dan and Matt who discovered they had complimentary areas of expertise. Matt began as an electrician about a decade ago and besides doing electrical work began working with HVAC as well. Dan had been doing contractor work in Alaska and when they met they realized they were a perfect match to begin a business, hence Allred Heating, and Cooling and Electrical. Between the two of them all of the right bases were covered to offer complete electrical and HVAC systems, both installation and repair. Allred Heating Family Hopes to Help Your Family We are a family owned company and we know how important it is to keep our homes working economically and safely. We hold ourselves and our work to the highest standards and that is why we offer a one year parts and labor guarantee. We are bonded, licensed and insured to and we’d like to show you why you can have the utmost confidence in us. We will give you upfront estimates so you’ll know what your bottom line will be.

"I recommended AllRed to my mother, they told her that they would give her a 10% discount on the phone when she called. They only gave her a 5% discount, they also didn't provide any information about the system? No information was provided also about health of system or checkpoint system used; (PSI of freon, lubrication, filters, drain lines, etc) When I called up Allred and asked for them to provide the 10% discount like they promised they said they would, and she would see it on her Credit Card. A couple of weeks went by and nothing. I called again, they apologized and said they would follow up ensure that the service team sent the information to us and provided the discount and called me back directly. After another week, NOTHING! While the work was completed successfully. The communication and follow up of this company are terrible to say the least. I wouldn't recommend Allred to anyone, or trust them at all :-("

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!"

FAQs for geothermal heating or cooling system installation projects in Mountlake Terrace, WA

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.

The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.

Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
