This crew deserves far more than five stars! This was hands down the most pleasant experience I’ve ever had with a contractor working in my home. From the very start of the day, communication was outstanding. I received a text with a live Google Maps visual showing the technician’s location and arrival progress, along with the names of the team members, the vehicles they would be driving, and even the license plate numbers. That level of transparency immediately made me feel comfortable and confident. Every employee who entered my home was kind, respectful, and genuinely a joy to have around. The work was completed efficiently and exactly within the timeframe I was given. They cleaned up thoroughly, walked me through everything that was installed, and made sure I knew how to use it all. They even asked if there was anything else they could help with before leaving. It was an absolutely amazing experience, and I would use this company again without hesitation. I will be referring them to anyone and everyone who mentions needing heating or air-conditioning installation or repairs. As a side note, they also offer services beyond what most HVAC companies do—I believe they even service boilers, which feels like a blast from the past in the best way. A huge thank you to Jeff and his entire team for taking such great care of me and my home—and for being so patient and kind about my sweet pets, who were very eager for attention throughout the day! Ron, Devon, Victor, and Danny were all incredible. Thank you again for your outstanding service!

They arrived on time and were communicating throughout the project. I wish I could remember their names, but they were polite and professional. Worked clean and quick and took the time to go over everything that they did before they left. The price for the work was very reasonable for having to seal off and reroute the gas line to my fireplace. Highly recommended 10/10
Green City was great from estimate to the completion of a condensing boiler install. Jeff's crew that did the install were very friendly and knalagble. They answered all my questions. They verified with me were I wanted things to be placed from the boiler to the exhaust and intake pipes. I use me attic for storage and they made suer that the piping would not interfere with that. At the end of the install I had heat in my house. Theye had everything cleaned up, hauled away the old boiler and parts all in one day. There were a couple of minor things but Jeff had them taken care of the next day. I'm very pleased on how things went.
Was given a recommendation to call Green City Heating and Air and quickly got on their schedule for an estimate. The estimate was almost 50% less than a bid from another company. I liked they gave two options to choose from. Once I selected, I was on the schedule for the following week. I even had some ad-hoc electrical work that their electrician (who had to add a circuit for AC) was able to do during the same visit. Very much satisfied with their service and communication.
HONEST!! HONEST!! HONEST!! After a different company came out and told me my 10 yo furnace needed to have the motor replaced and that the parts were “discontinued” so they would just have to replace the whole thing, we decided to get a second opinion. We called our aunt, who said to call Green City because they are an honest, family owned company. I’m so glad we did! Damen came out, he immediately started cleaning the fan and that was all it needed! Seriously, all it needed was to have the fan cleaned. Damen was extremely pleasant and very kind and honest. He talked very highly of the company he works for which was refreshing honestly. We need more companies as honest and caring as Green City heating and Damen. When the employees are happy and taken care of, it shows in their work. Thank you so much for helping us get our heat up and running again! In the future, if I ever need help with my furnace, I will definitely call Green City.
