What Ottawa Homeowners Say
I had a great experience with Zenith Eco Energy regarding a service request for my AC. There was friendly and professional service on the phone to book the appointment, punctual arrival for the service call, excellent service and advice, and a competitive price. I highly recommend Zenith Eco Energy for your HVAC needs!
Excellent experience with Zenith Eco. They had competitive itemized quote. Installation was super easy. Arrived on scheduled time. Matt is very professional and answered all questions. Couple of days after, noticed minor issue with ductwork and it was addressed very promptly the next day.
I hired Zenith for a furnace replacement. Very knowledgable and helpful staff who made some recommendations, and found issues with previous ductwork. Would highly recommend for your HVAC needs!
