Energy audit worth it?
I will be upgrading my attic insulation (original ~ 20 years old) at part of some attic work and am trying to figure out whether an energy audit, to get the Enbridge rebates, is worth it.
The furnace was already replaced. And I don't think I want to upgrade the old tank water heater to a tankless.
So to do the minimum 2 upgrades required, that leaves air sealing and basement insulation (basement is finished with some original insulation on the upper half of the rear facing wall) as the other practical upgrades. I don't have a good sense of what air sealing entails..... Or whether a basement insulation upgrade would be worth it. Because it's a row townhouse, two of the basement walls (50%) around be excluded from the eligibility I think.
Just looking for opinions.
