They are very fast to react, and professional. Their work is high quality. The service is great.

I highly recommend Green Top Heating. My heater was not working on a Friday morning; I read some other Yelp reviews and decided to give them a call- I am glad I did. My heater is 20 years old, they came out, diagnosed the issue which was a heating element- got the part , returned and replaced it. That following Monday morning of the same week, my heater was once again blowing cold air, I called Green Top again, they sent a Tech out right away - diagnosed the issue, this time it was the ignitor - they replaced it with no extra charge. They were courteous and professional , I did not feel over charged at all! I will be referring them to my friends. Thank you, Green top!! J. Lawrence

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 Heatings estimate process was quick and easy. The installer's completed the two bedrooms and the living room mini split system all in a single day. Everybody from the start to the finish was courteous and professional and I will recommend them based on price and delivery to everyone.

Called on a weekend for a weekend emergency service for my furnace. They came in a couple of hours, had the heat going in twenty minutes, and didn’t charge me anything because it was just a tune up. I called around and one place was going to charge me over $500 just to look at it. Amazing service!

Came in time, fixed as fast as 30 mins, and very good customer service. It was a pleasure to be your customer guys!

Our heater was taking a long time reaching the temperature setting on the thermostat. Tech came early to our appointment discovered the problem. A smart tech. This is a good company and I strongly recommend you give them your business.

Greentop was amazing! We got 3 mini splits and a heat pump installed. Andres quoted us 8k less than other companies, with the same parts and warranty's. Mark, Evgenij, Dylan and Alexi installed them efficiently and professionally all in one day. They showed and explained all the work and were very knowledgeable. Everything was done with care and precision, they even went into the crawl space the run the wiring properly. Would definitely recommend!!

Hello, We rent the house, which had very old heating system since 1959, this fall season the system broke, and it cannot be restored. The owner of the house, contacted countless heating companies, and they all came, but only Greentop was on top of everything. Fast, reliable, fair price. They started to setup new heating system right before the recent storm, and next day they came like nothing happened with the weather. I have to say they I was afraid that I need to do cleaning after the setup, (I didn’t want to as I was on my vacation), BUT guys did everything super clean and neat, I literally do nothing after they finished. I’m very pleased and satisfied with their job. They are professionals. Igor, Yaroslavl, Vladimir, those guys were very nice, polite, professional and fast. I highly recommend Greentop Heating company. They installed gas furnace in three days, now we finally have heat at home. Thank you very much! P.S. Also, they explained everything what needs to be done and how to maintain clean filter.
