DeMark Home Ontario

Just put in new Furnace, AC and Tankless water heater for my home. Used demark home ontario as suggested by my friend who used their services previously. As my friend said company and their staff is very professional and stand behind their reputation. I had in home estimate and then booked installation. Demark home offered me a very good deal since I got all 3 units from them and they also offered me free Nest thermostat with the installation so I am very pleased with my choice. Technicians were very professional and finished installation of all 3 units in one day. I recommend demark home ontario for heating and cooling services. Thank you. Nik from Niagara Falls.
