Andrew and his partner did phenomenal workmanship at an affordable price. I had these guys install 2 new air conditions in our commercial lease property; from the get-go they assured of a hassle free convenient installation. They were very generous with the pricing, as I got pricing from 3 other contractors! I recently had them replace the HVAC system in my personal residence which is over 30 years old. These guys are not your ordinary contractors, as they hold engineering degrees from Toronto. Great to see young guys with professional degrees putting hands on in the trades and showing quality customer service! Would recommend to everyone~ Thanks again Polar Dynamics!
