I am one of those who normally doesn't give a review (I know, one of those), regardless if the service was all right or even when it's not-so-great. However, my whole experience with GreenTop is worth writing a review to let people know how great they are to work with. I had contacted a competitor when my furnace started to go on the fritz. Wasn't really ecstatic with the competitor's service, but it did result in them telling me I needed a whole new furnace. Then they said it would AT LEAST take 2-3 days to have one of their technician come out to look at it and they wouldn't even guarantee they could install it the same day. Maybe during another time, that timeframe would be acceptable. Yet, approaching what would be forecasted as one of the coldest set of days in the year, that just couldn't work for me. In the middle of night, I was looking for furnace repair and GreenTop popped up due to all their 5-star reviews. I had not previously heard of them and maybe they didn't have reviews ranging in the hundreds of thousands like some others, but the reviews I did read were all spectacular. Either in their customer service or in the quality of the work they did. I did their "Job Estimator" and within a few hours, had been contacted by Ruslan. From that point onward, the customer service was the BEST and he had his crew at my house within an hour. They were super friendly and also very informative as they answered all my questions. By later that morning, I had a new furnace up and running with no disruptions to my day or any ongoing issues. Just in time before the storm hit. I hope that when reading all the reviews, it conveys on how great GreenTop is. They have changed what would have been a bit of sour news (having to buy a new furnace right before a big snow storm) and made it a better experience overall. I already have it in mind to use them to replace my water heater later on this year since they did such a great job and the customer service is exemplary. Thanks Ruslan and crew! read more

Simply the best nicest, thorough, and responsive HVAC contractors I have worked with. I recently used Greentop to replace my gas furnace with a heat pump. After getting quotes from numerous installers, they were among the most competitively priced for the Mitsubishi hyper heat system I wanted. Other companies also with "green" in their name wanted nearly double the cost for the identical hyper heat system, and tried to push me on a worse Diakin system that required backup gas or electric strips. Make sure to quote around! Through out the process Andres and the rest of the team was always extremely prompt to respond and easy to work with. A few weeks later we scheduled in the install and I had our new heat pump! Hena and Mark did a fantastic job on the install working quickly, thoroughly and they even cleaned up after themselves when they were finished! Somehow cleaning up seems to have been forgotten by most other contractors these days. A few months later, I realized that the heat pump they installed was actually the non hyper heat version of the system. Their quote had hyper heat in the description, but the model listed was actually the non-hyper heat. I called Andres back and explained the mixup. I was worried that they would dismiss my request since the job was already completed, but Andres and Greentop supported me through out the process. Since there was shared responsibility for the mixup we agreed to split the cost to upgrade me to the correct hyper heat system. After a few weeks Hena and Mark came back out and swapped out my outdoor unit to the correct hyper heat system in an hour and half start to finish (and they cleaned up again)! Overall I can't recommend these guys enough. read more

They have awesome ratings for a reason. We got estimates from five different companies for replacement of an electric furnace with a heat pump. We limited our selection to those companies that were Mitsubishi Diamond dealers as that was the unit we wanted and we felt that having such a relationship might have some faint extra bit of influence if there were problems. They gave us a very good bid and installed the unit over two days. The install was tricky as we have an older condo with a very tight space for the furnace and a very unhelpful electrical panel location. The installers, Adrian and Sergiy were splendid, working very neatly and leaving zero debris in the house. They observed mask protocols and also wore booties to protect floors and carpets. While that seems obvious, some vendors are not as conscientious. A few holes needed to be cut in the drywall to route wiring and line sets. We were told this in advance and had no issue with that as we can hardly expect a complex bit of equipment to be installed without some cutting of existing walls. They did offer to send a drywall repair person to fix the holes later but we are doing further remodeling so declined that offer. In every case they were responsive, accommodating some calendar changes we needed. The work went smoothly and we are completely delighted with the results. I would have no problem at all recommending Greentop for even the most challenging HVAC jobs. True professionals. BTW the install of my heat pump cut my daily usage by 40% thanks to the daily readout of usage from Seattle Light. read more

Green Top Heating & Cooling was one of several companies that I had contacted for estimates on a Mini Split ductless heating system. Ruslan B. (the owner) arrived and did a walk through and suggested what would be the most beneficial for my home. I was given a detailed estimate which outlined exactly what you were purchasing (equipment, model number, etc.) on the same day. There was no up sell, just plain honest answers which was greatly appreciated. Their pricing was competitive; however Green Top Heating & Cooling was my choice based on integrity. Ruslan, Vova and Roma arrived on time and did a phenomenal job installing a Mitsubishi 2 Zone mini split ductless system. The team worked so well together and took great pride in their work. They ensured that my bamboo floors were protected and anything else that was nearby and cleaned up all the areas they worked in. From start to finish, the installation was completed in about six hours. Couldn't have asked for a more professional and knowledgeable team of installers. Ruslan explained how to use the system and answered any questions that I had until I was satisfied. I am enjoying my system and wished I installed this a long time ago. The office staff Coco, Julia and Olga were wonderful to work with. I would highly recommend Green Top Heating & Cooling and would do business with them again. read more

Ruslan of Green Top has been a pleasure to work with on my heat pump installation project. I had several bids done and he was excellent at communicating with me from the beginning to end. His price was initially very fair and he gave me three price options for different units. After some discussion about electrical changes in my box, he was actually able to lower the bid a bit. During the inspection he noted a problem with my existing heating unit filter and offered a solution before the work was started. With the subsequent changes in required work habits due to the virus, the price initially quoted was not changed, even though the costs for him had to be higher due to the measures needed to protect both his workers and the occupants. The work started on time and was done professionally. Ruslan sent before, during and after pictures as I could not be there when the work was done. The work started on time and was done professionally. If you are looking for good pricing, quality work, workers that show up when they say they will and good communication skills from a contractor, Ruslan and Green Top are your answers. If I could give Green Top 10 stars, I would. I highly recommend Ruslan and his company. read more

GreenTop has been the absolute best. From the moment Andres stepped into my home I felt at ease. He knew exactly was he was doing and made the impossible possible. I had three estimates before Andres arrived to my home - none of them could do what I wanted. Andres made every effort to provide the best estimate possible. Crawling around every attic space, on and off ladders, really looking at what I was asking him to do and, every step of the way, it was "no problem." He accomplished what no one else could. Andres is the best! Scheduling with Andres and Vera was the easiest thing ever. They moved quickly and they were able to get the job done fast in this heat. Alex and Vova P finished the install seamless - it was like they were never in our home, other than for the amazingly cool air we were receiving. The house was SPOTLESS after they left. Ruslan is kind and communicative. The house is perfectly cold and the machines are wonderful. The City of Seattle inspectors were incredibly impressed with their work and closed our permits within minutes. Thank you for making our home perfect! We recommend this company to anyone. They can do anything you ask! read more

GreenTop Heating saved the day! After moving into my new place, I realized one of the vents wasn't blowing any air at all. As a new homeowner, I had no idea what could be wrong or how serious the issue might be. I called GreenTop Heating, and their response was incredibly prompt. They managed to send a technician to my home the very same day - talk about efficient service! The technician was both professional and honest. He only charged a $1 diagnostic fee to assess the situation. It turned out that a simple cap was blocking the vent, causing the lack of airflow. Instead of trying to complicate the issue or suggest unnecessary repairs, he quickly resolved the problem. What impressed me most was their fair pricing. The technician only charged the minimum fee for his service. It's rare to find a heating company that prioritizes customer satisfaction over making a quick buck. I highly recommend GreenTop Heating for their: Rapid response time Honest diagnosis Fair and transparent pricing Efficient problem-solving If you're looking for a reliable heating service, especially as a new homeowner, GreenTop Heating is definitely the way to go! read more

It's hard to put into words how great of an experience we had working with GreenTop on the installation of our new air handler. First, after waiting over 2 months to get an estimate from another company, I contacted GreenTop Heating and they sent an Estimator, Andres, to our house the same day. Andres was personable and professional, on-time, and was able to give us a quote before he left. On install day, two technicians, Vovochik and Igor, performed the work. We have recently been remodeling and upgrading parts of our home, and working with GreenTop's technicians was night and day different than other contractors. Their work was flawless, they were in and out, and everyone was super professional. Finally, I mistakingly thought that I had ordered a specific smart thermostat (a Nest), that was not compatible with the heating/cooling unit. Andres, Vovochik, and Igor bent over backwards to make sure I was happy with my install, even though the mistake was mine, not theirs. Truly superior customer service, which is so rare these days. I cannot say enough good things about this company! read more

Hats off. I couldn't recommend Greentop more highly. Outstanding company. Outstanding people! Responsive. Thorough. Diligent. Unbeatable service. Unbeatable pricing. We love our new Mitsubishi ductless system. Our fifty-plus year old house is built into a steep incline in many levels. The third zone required ingenuity and critical thought. Separated by two flights of stairs it seemed impossible to accomplish without creating enormous cosmetic problems inside. Andres assured us if anyone could they would. Thinking out-of-the-box Volodymyn and Sergey did just that. Things got iffy again when we discovered our long outdated electrical panel couldn't support our plan.That's when I discovered Ruslan is a man of his word in every regard. Katrina who stayed on top of the invoices and the job for us in so many ways. And Oleski who just installed the surge protector we needed given our location. John who helped with the paperwork our tiny public utility company required. Greentop's teamwork excelled in every way. Forget 5 stars this fine company deserves 10 stars. Thank you Rusian! read more

I just had a new Gas Furnace + AC installed by GreenTop. Getting the quote for cost: Got quote via messaging after read about reviews here and compared with a few other company plans. The good thing is that they cut the commission-based sales layer thus cut cost for customer. And reduce the stress of high pressure sales from traditional sales person. Safe me time as well. Ruslan get back to me in a few hours and tailor the system for my focus. Very smooth process. Installation: The crew show up on time, skilled and shows courtesy. They did wonderful job. I like their honesty and can feel they value customer satisfaction very much. An example is that on the installation day they found my existing furnace was downflow style that they could not get the same style brand+equipment in time, and mixing furnace of other brand is hustle. They ended up substituting a high efficiency model while honor original quoted price. I am happy with this new HVAC system so far and looking forward to work with them for maintenance. Thank Ruslan's and the crew for good job done. read more

I needed to upgrade my heat pump/air conditioning system 6/2025 and contacted several companies for an estimate. Greentop was quick to respond, Alex came by the next day and assessed my current system and provided options for an upgrade. He was very knowledgeable and gave me a detailed written estimate the same day.. It took another company 14 days to provide an estimate. The cost for the recommended system was very competitive and installation could be completed the following week! On the scheduled installation day, Hennadii, and Roma arrived on time and did a quality job installing the new HP and Air handler. They cleaned up all debris before leaving. I've had the new system for about a month and everything works as it should. I was so impressed with this entire company that I'v erecommended them to others . Many thanks to Alex, Hennadii, Roma ,Katrinna, and those that helped with this project. Customer service, and skill level are 5 STAR! I will select Greentop for all my future HVAC needs. read more

My old heat pump quit working on November 5. This is the worst time as we had been having consecutive cold days. My wife and I were lucky to have a mini split in one of the bedrooms. I made my first contact to Greentop on November 9, received a same day reply with a site visit firmed up for the 10th, received an estimate in the evening of the 10th, firmed up the installation for the 12th and had a working Bosch condenser along with my existing air handler by the end of the day. The team has a streamlined and highly efficient process which allowed me to minimize my suffering during these cold days. Greentop did not take advantage of my hardship and gave me a very reasonable price. The team was professional and paid attention to all details including moving equipment in and out through a difficult or not properly maintained sidewalk area. The Bosch condenser uses inverter technology and has been working very well with my old air handler (a US brand). read more

Our gas furnace suddenly stopped working on the night of Dec. 08,2024. Called up 3 contractors and compared them side by side. One of them gave a very detailed description of work while GreenTop did not. However, I took a chance to take them due to limited funds since they are the lowest. After signing off the contract, they came exactly at the appointed time of 8:30 am, the guys brought several rugs to avoid dirtying my newly installed wood floors, they work diligently and efficiently for the next 7 hrs, barely taking a break except during lunchtime for 30 minutes. They meticulously did their job in a very clean and professional manner. They even clean and vacuum nicely the base where the new furnace is to be installed. To Olexii and Hennadii, thank you for a job well done. Happy to refer to GreenTop Heating for people who will be in a similar situation as mine. Appreciate your work. Edgar of Seatac read more

I called Greentop for a bid on a furnace replacement and was provided an appointment for the next business day. Andres came to my house to give me a bid, arriving on schedule and not only did he give me a quote right away but he told me they could have it installed that week. I called the next day and got the job scheduled. Mark arrived on schedule to do the install and got started right away. Andres showed up after a bit and helped until his first appointment. The furnace I had installed in my previous house (by another company) took almost all day, mostly because the techs were often going back to the shop to get something they needed for the install. Mark had no such issues. He was very prepared; had everything he needed in his van and he just did the job. The new furnace was installed, running well and the area cleaned up all inside 3 hours. Thanks guys! read more

I called Greentop Heating & Cooling late yesterday because my husband thought the blade on our Mitsubishi heat pump unit was bent. Greentop had installed it two years ago and we have been very happy with our experience with them and the product. They came first thing this morning at the time they said they would be here and did a thorough inspection of all the inside and outside units. They explained the mechanics of the unit and found everything working properly. I asked if I could pay him for the service call and he said they never charge for diagnostics. He was so gracious and professional I almost felt bad for not paying him! Everything from their timely response to their communication with the customer is incredible. I will always use them for my heating and cooling needs. Trust is something that is earned and they certainly have mine. Thank you. read more

I could not be happier with my experience with GreenTop Heating & Cooling. I got several quotes for a new Mitsubishi furnace and heatpump and GreenTop was the clear choice. Andres was extremely helpful when he came out to give a replacement estimate and set the tone for the whole process: thorough, quick, attentive, and respectful. I accepted their bid the day after they came out for the estimate and they had me on the schedule within a week. I am writing this on install day 2/2 and thrilled with the work so far. They show up on time, work really hard, don't complain, and clean up after themselves. Not much more I can ask for. Thank you, GreenTop! Update: my house is warm and my basement is cleaner than when they arrived. I'm really impressed. Best HVAC value I've found around Seattle by far. read more

Our furnace was putting out horrible smelling gas into the air and needed to be replaced basically immediately. Ruslan responded to my e-mail inquiry within 15 minutes - on a Sunday night. He quickly put together an appointment for an install less than twelve hours from when I contacted him, and sent an estimate that was right in line with what I was expecting to pay. Alex showed up first thing the next morning and got the new furnace installed in about four hours. Now we can have peace of mind as we head into another cold snap. Everyone I interacted with at GreenTop was prompt and professional. I would not hesitate to reach out to them for any heating needs, especially if it's urgent. None of the other businesses in the area got back to me with a personal reply nearly as quickly. read more
