Haunted House was watched live by 2.97 million U.S. viewers and got a 1.2 rating/4 share in the adult 18-49 demographic. Haunted House received mixed review from critics. LaToya Ferguson from The A.V. Club gave the episode a D+ and cited "With [the previous episode], it looked like the show would slowly improve as the season went on. So watching Haunted House is like watching the erasure of that improvement, simply by being an even bigger mess than the show started with in the pilot". IGN's Terri Schwartz gave the episode an 8.4 out 10, saying that "Scream Queens might have gotten heavy-handed with the exposition in its fourth episode, but it still delivered some exciting twists and remains a joy to watch". Patrick Sproull from Den of Geek said that "Scream Queens remains engrossing television and Haunted House greatly improves things by spicing up the core mystery. [The episode] was moreish and had me itching for the next instalment more than ever before. Caralynn Lippo from TV Fanatic gave the episode 3.75/5.0 stars and said that Haunted House "was a bit of an uneven hour but had its share of laugh-out-loud moments and memorable performances", and praised the performances of Keke Palmer and Glen Powell.
