Yes, it'll work fine. Or at least it will work no better or worse than if there was CU wiring.
Unless it was wired improperly the wiring is going to have rougly the same impedence in an AL wired house as a CU wired house. The terminations will be roughly comparable, etc, etc, ad nauseum.
Yes, AL is not generally great to have in a house because of the extra hassle if you need to replace any hardwired piece of the electrical system. On top of that is the additional worry that whoever wired it did it wrong (inspection or no inspection), or any home owners over time wired something incorrectly or that you don't wire it properly.
AL isn't necessarily a terrible idea. AL is what is used in powerline wiring and its what comes in to your house to your breaker box. Its generally more cost effective for larger gauge wiring. The issue is, it is not as flexible, it has a higher coefficient of expansion than aluminum, which means that terminals and wire nuts can come loose over time, especially if they were not made for AL connections. Since no one had worked with AL (not really) previously, all the experience was in CU terminations and wiring so there were a lot of problems when AL took over in the 70's and then sanity and metal prices changes and everyone switched back to CU wiring.
If you want to find something real crazy, look at the plumbing in my 1961 house for the exact opposite metal price experience. It isn't iron, it isn't steel, it isn't clay it isn't PVC or ABS...its Copper. Because in the early 1960's copper was dirt cheap and its easy to work with...so why not use 4" copper drain pipes (I probably have well over a $1,000 in CU drain pipes in my house at current scrap prices)!
