Extremely professional and great quality service and completed the job in no time . Thank you and I will recommend you to all my friends and family
We used City Energy to install a furnace during a renovation. We got quotes from 3 companies and City Energy was the most cost competitive and creative in configuring new ductwork in a tight space. We have used them twice for repairs on another furnace and both times they arrived quickly and carried out the repair professionally without trying to upsell us on a new furnace. Highly recommend.
Absolutely great experience. He was very honest and took time to explain everything.
