2 stars only because Frank so polite , he responded to my call on Sunday and send a team Monday, Monday 23 June 2025 during the heatwave, Immediately when they entered the house they seemed hostile, I tried to ease things by offering them beverages or coffee,one of the team members started to complain about the temperature, clearly in my house only was the temperature like that and I am responsible for the heat wave in Canada, after 30 minutes, they said that they received an urgent call , so they want to leave , I told them I am a new resident In Longueuil, and there’s only one lamp if they can install it, they replied it’s an emergency and they can’t stay , so they left after 10 minutes they came back with a bill of 287,44$ , no description on the bill, clearly Money is more important than the emergency , so I paid the amount just out of respect of the response of Frank on Sunday.
No judgement here , but this is last time I call this company.
