It has been more than a month since Laurenzo came and fix my furnace. Everything works fine since then so I am writing the review now. (you got to give it sometime to make sure everything works properly) Laurenzo and Westmount Heating are as great as everyone else described in here. Professional, detailed, friendly and reasonable price.
My gas furnace was not turning on, and since it is a bit aged, (about 10 years) I was ready to open my wallet and spend a fortune on it. Upon Laurenzo's arrival, he quickly check around the furnace and locate the problem in 5 minutes. He patiently explain the problem to me and recommended to apply fix to it for now and wait for the rebate season to replace for new one which can save me hundreds of dollars! After he fix the furnace, he also spent time to look around my house to provide suggestion on how to make the heating process more efficient and so on.
Strongly recommended for anyone who need a service. The only problem you might have is to get an appointment with them!
