Customer Reviews

Christmas Eve and our furnace decided to take a holiday. Phoned Green Heating and Air and the technician was here in 20 mins. He completed a repair but warned that we may need a new circuit board. Sure enough the furnace shut down again and when we called back they confirmed they had a board and could install it after midnight. Exactly at midnight our doorbell rang, the circuit board was replaced and we’ve been warm and toasty ever since. Thank you for going above and beyond on Christmas Eve. 100% recommend this company which truly provides 24 hour emergency services.

When my furnace quit this winter the folks from Green were at my house within 30 minutes. They quickly diagnosed the problem and provided a budget friendly quote for a replacement. A crew was there first thing the next morning and had everything running within 2 hours. Hassan, Andre and his crew were very professional.

Benjamin J.

Hassan and his team completely replaced my boiler and got it up to safety standards in my old home. Hassan addressed every issue we ran into and responded to my calls and messages very quickly! He was very friendly and was patient in answering all my questions. I highly recommend him and his team, and feel confident that I have them to turn to with any issues regarding my heating!

Gianne H.

Wow so impressed at how quickly the team at Green Heating & Air responded. We had our heating breakdown one evening and in the middle of winter, it’s never fun sitting in the cold. They arrived early the next morning and was able to fix the issue with our boiler and tank immediately. They were transparent about the price and process, and what products they needed to purchase.

Michelle K.

Hassan is amazing. We have a new build home with a heating system that is terrible. We had an issue and called Hassan who came to fix the issue. While fixing the pump, he told us how terrible the system we had was. He recommended getting a new system. My husband and I agreed.Hassan installed the unit and was a 100% correct. My house is 100% warmer, the hot water is so hot. He is a man who knows exactly what he is talking about. Please listen to him and trust him you won’t be making a mistake.

Aruna K.

If you think great customer service is a thing of the past, then you have not worked with Hassan and the team at Green Heating and Air Inc. They did outstanding work in installing a new AC and air handler system in a very tight furnace room serving four floors. The project was done on time with no budget surprises and after installation follow up was something you rarely experience today. Cannot say enough positive things about our experience.
