I hate to say it, but if you wanted to side with with either House or NCR then you did it wrong - you have alienated both factions in one go. Basically, you have progressed too far into the House questline, specifically by speaking to him and agreeing to having carried out his requests. If you think about it, it makes sense - NCR and House are rival factions, and if you go agreeing to House's requests, then the NCR won't be happy. The NCR wouldn't want you speaking to House, and that is what you have done. You can't follow both factions all the way; up to a point, yes, but there is a cut off where you have to pledge allegiance to a faction and stick it out.
Just reload your last savegame before you spoke to House, and all will be well.
That's what is great about this game - choice and consequence.
