I have used A Number 1 Air previously so they were the only company I called for a new system install when mine gave out recently. After the job was completed it appeared it was done correctly however the next day, I arrived home from work to a very strong odor of natural gas. I called for another tech to come out who used a meter around the gas lines/ fittings on the furnace and this confirmed that gas was escaping through a fitting. This could have resulted in a serious consequence to my family and home.
