Excellent service, very professional team. Transparent pricing and communication. I’m looking forward to working with Green Flow again
It was a pleasure doing business with Green Flow. They kept me informed during the the entire process. The tech (Andrey) was knowledgeable and knew exactly what the problem was with the furnace. The furnace motor was installed the next day and I am satisfied with the job,...
Efficient, polite and professional.
Timely and friendly service, highly recommended.
I needed a thermostat installed. I called one day they were there the next day. Installed the thermostat and made sure it was working before they left. Came back the next day because no heat was coming out the vents and fixed that issue. No problems since. Thanks...
