We also started the lower level HVAC. We only have 4 vents to put in so it shouldn't be too hard. There's still a page long list of odds and ends that need to be completed, but hopefully in another week (or maybe two) all our rough-ins will be complete and we can call for an inspection. We'll be just a few weeks shy of 6 months from the time we got our building permits. The project is moving along a bit faster than I thought it would.
