While Kirkland, Richmond and Seattle locals are used to the constant rain and piercing coastal wind, it doesn’t mean that it doesn’t take a toll on their homes’ HVAC systems. King County HVAC systems are required to handle one of the rainiest climates in the country, while also cooling and heating homes that are both beachfront and high up in the snowy mountains.

Our goal is to help Seattle locals not have to worry about their outdoor unit rusting, or whether or not their furnace is ready for the winter ahead. Rather, our customers can spend more time kayaking the sound, biking Snoqualmie Pass or just enjoying the views of Ranier, while we take care of their homes’ heating and cooling needs.

Why We Love King County

Originally named after the 13th Vice President of the United States, William Rufus King, King County’s namesake was changed in 1986 to honor the late Martin Luther King, Jr. There is no better icon to embrace the area’s commitment to diversity and overall betterment of the world. Seattle, Redmond, and Kirkland are three of the nation’s greenest cities, boasting some of the best air quality in the country thanks to the area’s dedication to preserving the natural habitat that surrounds the cities. We strive to uphold this effort to improve the state of our global ecosystem by providing the most efficient HVAC products and renewable energy solutions in Seattle and its surrounding areas.

There’s no question that the birthplace of Starbucks has a great energy surrounding it. Though the weather can be a bit dim, Seattleites are known for making the most of what they have. With the Puget Sound and its many islands, the Cascades, rain forests, and more typical city attractions like the Space Needle and Pike Place Market, there’s a lot of unforgettable things to do in King County. Whether you’re working at one of the area’s 8 fortune 500 companies, or a true WAnderer, it’s no surprise that you, like us at All Climate Heating & Air Conditioning, love King County.

We’ve been customers of All Climate for nearly 20 years. Their service techs are always friendly and professional, and they do top-notch work. There’s a reason we’ve stuck with them over the years: they’re pros who know what they’re doing.

Carrie Booth

After a couple summers with an AC outage during the first hot week, we decided to have All Climate come out for spring maintenance. They call when we are due, and they have been punctual, efficient, fair and knowledgeable.

Ethan Turk

I worked with Dean to have a new Heat Pump spec’d out and then they sent a crew out to install my new system. Dean was professional, efficient and gave me a very competitive price out of the gate. No haggling necessary! The installation was turnkey. They set the system up to work with my existing Nest thermostat. They arrived on time and got everything completed in a timely manner. Very happy with the service every step of the way.

Nettie H

Very polite. Worked quickly and efficiently to get the inspection done. Really nice customer service personality. Thank you!

Patrick Ennis

All Climate is THE BEST. They’ve done 3 big jobs for us in the last year and they are wonderful all around. In my 55 years on this planet i’ve worked with a zillion firms and All Climate is at the top of the heap. They are prompt, courteous, skillful, chock full of expertise and cost effective.

Liz Sexton

We’ve had Nathan come by several times for a furnace issue and he is just the best. Really seems to know what he is talking about, worked with his colleagues to find a less expensive fix, and is just an all around nice dude. We look forward to having him come by and that’s big praise when it’s to have your furnace fixed.

George Tundrea

They are amazing! On a Friday afternoon, our water heater broked. Called All Climate, they send a technician on Saturday morning (week-end day!) and replaced it. Charges?: regular charge as if it was a work day! Amazing! We continue to use their services – as they also installed and schedule maintenance of our furnace on a regular basis. That is amazing too – another headache out of our plate.

Adam L. Edmonds

All Climate installed a new gas furnace, electronic air filter, pump, and cleaned the ducts prior to install. Installers were clean and courteous. The bid was second from the bottom of the pile in terms of cost. Their sales person was knowledgeable and was able to respond to our many approaches to h


Reliable, friendly service. I’ve worked with a lot of home service providers and All Climates really stands out. They called the day before the job to confirm appointment and arrived on time. They also confirmed pricing prior to starting the job, which is a big thing for me. Jose was friendly and

Dick and Gail Redmond

Great company. 6 months ago I had a York two stage gas furnace installed by All Climate in Redmond. I invited six companies in for a quote. My sales person was pleasant and competent. All Climates quote included things that the other companies would not do or charged more for. The installation crew

Robin Smith

I had HVAC maintenance done by them and they were very prompt, fast and thorough. I knew that I needed another part to be replaced; they ordered it, called me and performed the replacement within the next two weeks. Very professional and extremely competent! I will definitely use them again.

Risa Schmidt

Requested an estimate for a new furnace. We were referred by 2 of our neighbors who have used this company before. We were quite impressed with what information we were given and will be using them when we replace our furnace. Anthony was very polite and explained everything to us in very plain and simple language. We trust Anthony’s explanations since he is not a sales person but one of the equipment installers and we trust that perspective on a product.

Chris & Ginny

My first experience with your company was when the heat went off in our rental house in Seattle on a Sunday night. I made a couple of calls first thing Monday morning and only your people understood the urgency and arranged to meet me at the house within the hour. I was amazed at the efficiency and professionalism of the crew and felt confident with their work.

George and Eva

Just a note of appreciation for the service Kip has given our heating and domestic hot water system. He has never seen or heard of the model we have, but took the time to research and find the information on the unit. We are thankful for his dedication and service… Thank you for sending him!

M. Kadlec

Good sales person, good staff, good price, good service! Their quote was the best of 3 estimates we had and the installers arrived right on time and did a great job. The staff was very friendly, I highly recommend using All Climate.
