When our furnace broke, we took the opportunity to get some of the government grants for installing and energy saving furnace. In order to get the grants, we needed an audit to show that we did in fact increaase the efficiency of our home. Mark W from F2 was selected to come out and do the audit. He was quite thorough, taking a few days to do many of the tests. After the audits, he gave us additional options and recommendations about how we could increase the efficiency of our home, as well as take advantage of other government grants, both at the municipal and provincial levels.
