HVAC reviews in Kirkland, Washington

Daniel came highly recommended from our electrician and he didn't disappoint us. Our project, a complete remodel of a 1920 home, came with lots of challenges. Daniel came in quickly, assessed the situation, replaced our furnace exhaust system and moved our natural gas line in the kitchen to better accommodate the modern appliance and cabinets. Great service, communication, and price! We'll have him back to clean our venting system when the remodel is complete.

I sought multiple bids to install a new heating and AC system in my house. I’m so glad I selected Donso. Not only were their prices fair, but the work quality was exceptional. They worked full days, communicated every step, and finished exactly as they proposed. I didn’t realize the degree of creativity involved in engineering an efficient HVAC system. But Daniel’s years of experience were important to my design. My house is 50 years old and has been remodeled several times. The remodeling, however, focused on structural features without consideration for the HVAC impact. Daniel was able “fix” the air flow issues and make the house more efficient and comfortable. His years of experience in HVAC design were critical. I highly recommend Donso Energy.

Danny and his team are the best in the business. They are very responsive, clearly communicate and meet the timelines they promised. Thanks for doing a great job with our HVAC project.

Prompt coordination, competitive pricing, friendly crew, impeccable installation, and efficient turnaround! I needed to add A/C, upgrade heat pump, and a complete duct cleaning, and the team DELIVERED. Highly recommend!

I hired Daniel on his merits in his reviews, and he did not disappoint. He was communicative, professional, and dedicated. I highly recommend Donso Energy Solutions!

I have used this company on numerous projects as we are a commercial and residential contractor, Daniel and his crew always show up on time and get things done in timely manner.

Donso seems to be very reputable company. They are easy to deal with seem to be good guys. I hired them to replace the ductwork in my crawl space and they did a nice job. They came a bit later than I was expecting but completed the job a day earlier than expected so no problems. I would recommend them for any heating and cooling issues.

I am very happy that I hired Donso Energy Solutions for our Bellevue condo project!
I needed 3 new wall heaters installed which required them to be hardwired per Bellevue City requirements!
Also, the drywall needed to be cut and, walls patched and painted…
Daniel and his crew were very efficient and I couldn’t be happier with the quality of their work!
His price was reasonable compared to other estimates I received!
He gives free estimates and is excellent at responding if you have any questions!
Give him a call!

They showed up right on time and got straight to work. Everything was handled with care and precision. My home feels much healthier now.

Getting our dryer vent cleared at the same time was a smart move that significantly improved our laundry drying times.

The team used high-powered brushes to agitate the dust before vacuuming it out of the main trunk line. Their attention to detail ensured that not a single vent was overlooked.

We moved into a home where the previous tenant smoked, and the duct cleaning finally removed the lingering scent. It was the final step needed to make the house feel like ours.

I’ve seen a massive reduction in pet dander and odors since the team cleared out our main return air vents.

Moving into our new place felt much better once we knew the previous owner's allergens were gone.

Getting the air ducts sanitized was a quick and effective way to improve our indoor air quality overnight.

A beautiful place.

Great people and very professional. I would recommend to anyone.

great service experience, punctual, attentive, patient and cordial

This company did an impeccable job, I am happy with the result of the duct cleaning

Great job! years working with this company and they never disappoint me, on the contrary, I am more and more satisfied

My ducts were super clean, they definitely deserve 5 stars
