Quick Facts

Our Core Services

AC Repair

When cooling fails, comfort and air quality drop fast. We handle refrigerant issues, electrical faults, airflow restrictions, and control problems. Most parts ride with us, which speeds up the fix and reduces return trips.

Heating Repair

From gas furnaces to heat pumps, we restore safe, even heat. We test ignition systems, sensors, blowers, and venting, then verify performance with temperature rise and airflow checks before we leave.

HVAC Installation

A right-sized, properly commissioned system is quieter, more efficient, and lasts longer in Bellevue homes and businesses. We perform load calculations, match indoor and outdoor components, address ducts, and commission every system so it delivers the comfort you paid for.

Ductless Mini-Splits

Perfect for additions, home offices, and homes without ducts. Single- and multi-zone options provide targeted comfort with excellent efficiency, even in cooler weather.

Ductwork & Airflow

Comfort depends on more than equipment. We seal, insulate, and balance ducts to reduce losses and hot-and-cold spots. Expect better airflow, quieter operation, and improved efficiency.

Indoor Air Quality

Capture dust and pollen, reduce odors, and manage humidity. We offer filtration upgrades, air purifiers, and whole-home solutions that pair with your HVAC system.

Maintenance Plans

Preventive visits keep your system efficient and reliable. Members receive seasonal tune-ups, priority scheduling, and discounts on repairs.

We hired Green Top to install a 3-zone mini-split system in our home. Their quote was competitively priced, and the installation team did an excellent job -- they managed to get everything done in a single day, and their work was clean and high quality. Hennadii and Oleksii performed the installation, and they did an excellent job -- it's easy to tell they take pride in their work.
Responsive customer service, quality work and outstanding diagnostic price. I was looking for someone to help look at the my mini-split system. Sent in a project and get very quick response from GreenTop. Appointment set up was super quick. The technician came the day later to diagnose our system, and was able to tell us that the problem was not because of the system but different units were configured with different mode, so the system was not working. In the end, we only needed to pay the $1 diagnostic fee
Aleksi did a great job with our minisplit installation. We highly recommend.
I called Alex B about a concern yesterday evening and the crew was here this morning. My installation was three years old and the labor warranty had expired, but they took care of it without charge. Impressive customer service !
I had a fantastic experience with Greentop when they installed a heat pump system for me. What really set them apart from the other quotes I got was their creativity and problem-solving skills in figuring out the best way to run refrigerant lines without making them an eye sore. They don’t just opt for the approach that's the least amount of work for them; they really work with you to design a solution that fits your space and your needs. On top of that, their pricing is excellent--by far the least of the quotes I got. When installation day came (just one week after accepting their quote) they rolled up with an 8 man crew and completed the entire job in a single day. The inspection passed without any issues. I’ve already recommended Greentop to friends and coworkers, and every single one of them has had the same great experience. It's been nearly 3 years since their original install, and I've had zero complaints about the system. I had them come out to add a fourth head unit and decided that this company really deserves a review for their excellent work. If you're looking for quality work, thoughtful planning, and a team that knows their stuff, I can’t recommend them highly enough.
End to end excellent service on our heat pump installation. They provided us a very consultative quote with several options to meet our needs. The estimate was far less than other companies for the same equipment. Once we selected GreenTop, they were able to start installation within 2 business days. They did a great job on installation and the owner even called to check in and ensure I was happy. The inspectors said all was installed well. We’re very happy with the experience and would recommend GreenTop to others.
We just had a great experience with Oleskii. He came out in a reasonable time, worked super fast and explained the problem with our furnace. There was no diagnostic charge and he was so kind. God bless him and this company for coming out so quick during the winter time on a weekend morning. God is good.
Green Top Heating provided the best estimate to replace my 40 year old broken home furnace. Unlike other HVAC contractors, they didn't charge for a diagnostic service visit. The installation of the new furnace into the former tight location in the middle of the house and the connection to existing ducts, took only four hours. The service tech laid down floor covering leaving the carpet clean. They also applied for a Seattle mechanical permit, registered the system and scheduled an inspection. The project cost included a senior discount.
Green top was quick to my initial request. Tech Yaroslav was early and didnt waste anytime diagnosing the issue which thankfully was minor this time. No cost! furnace was up and running within 20 minutes of his arrival. I will be calling on them again in the future should my needs change and telling all my friends. I appreciate the honest integrity and the fact that did not slam me with some hidden cost. We need more businesses like them.
