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.

Service Area

We proudly serve residential and commercial customers throughout Bellevue and the surrounding region.

My first time using Greentop and it's all gone smoothly. I got a service call appointment within 24 hours of my original request and Yaroslav turned up on time to perform my furnace maintenance. He took before and after photos, cleaned up after himself and didn't try to upsell anything. The invoice came through as quoted and online payment was straightforward. I'll be calling on Greentop again when the weather heats up to run over the AC.

I believe that the quality of after-service in HVAC installation is very important, and in that regard, I am very satisfied with this company. I installed a heat pump a year ago, and recently, there was a manufacturer's valve issue with the heat pump. They came promptly the following day for a diagnosis, ordered a new part from the manufacturer, and repaired it completely free of charge under warranty. I was impressed with how perfectly they handled the aftercare service. Igor fixed the issue professionally and explained the helpful management methods well. I have been recommending this company to many people in my neighborhood. It is a great company.

We are returning customers of GreenTop Heating & Cooling, having used their services 4 or 5 times now, and they've consistently delivered excellent results at competitive prices! This time, they installed ceiling cassettes and an outdoor condenser for us. Igor and Alexey were the installers, and they did a fantastic job. They were professional, respectful of our home, and left everything spotless when the work was done. It's rare to find a company that combines great workmanship, reliability, and fair pricing so well. We'll happily recommend GreenTop Heating & Cooling to anyone and will definitely continue to use them for our heating and cooling needs. Thank you for another outstanding experience!

We have AC installed at our house in Seattle by GreenTop Heating and Cooling, the technicians from consultation to installation are very knowledgeable, professional and highly efficient! They arrived on time, and completed the installation as scheduled. They cleaned up right after operation done at each spot of the house and are very polite. The price they offer is also very rational. I will definitely recommend GreenTop Heating and Cooling to anyone who needs to install AC.

Greentop did an amazing job! Fast, responsive, reasonable price, and got my heat pumps working during the heat of the summer in less than a week from when I called them. Give them a call, they’re great to work with!

The team has great communication, the tech was on time and very knowledgeable.

Adrian Aro was great! He was friendly, efficient and knowledgeable and seemed very detailed oriented which was a big plus. He explained what was being installed and showed us how to maintain the unit to keep it running efficiently. In the beginning we were questioning if we made the right decision to go with this company but in the end Adrian put us at ease with his excellent work. He is such an asset to Greentop that we will highly recommend this company to family and friends.

My mini split system wasn't working properly and I called Greentop. They had a tech out to my home within 24 hours. The tech was professional and efficient and had my system up and running the same day. I received good communication from the main office and I couldn't be happier with the service we received. I highly recommend this company!

Greentop did a fantastic job installing two split system air conditioners in our house. They completed the project in 2 days and left our house clean and feeling so much cooler! They were professional and great to work with!
