Reviews for the album have been mostly positive. Rick Florino of ARTISTdirect was the first to review the album, describing it as "a high watermark for the Boston group" and "the best hard rock record of the year." Revolvers Richard Bienstock gave the album four out of five stars and praised its title track, which he felt was up there with 'Whatever' and 'Keep Away' in terms of tone and delivery, and commended the band for pushing their boundaries on several songs such as "Nothing Comes Easy" and "Something Different." Bienstock concluded his review by saying, "With 1000hp, Godsmack offer up a few new sounds, while at the same time remaining firmly resolute in their musical mission." Similarly, About.com music journalist Chad Bowar gave the album four out of five stars and praised the band for keeping things fresh while "never straying far from their signature style." Jeremy Thomas of 411mania.com gave the album an 8.0 out of 10 rating and praised the band for "adopting a few forays outside of their core sound without ever straying so far as to fall off the path." Thomas noted that, while 1000 hp "isn't an all-time great album," the band "delivers some great hooks on the album" and that "There isn't really a weak track amongst [the album's] ten songs." At The Boston Globe, Maura Johnston gave the album a favorable review and described its sound as "leaner and meaner, and a bit nostalgic, too." Another favorable review comes from Chad Childers of Loudwire who felt the album "succeeds in bringing the hard in heavy doses with just the perfect smattering of melody in just the right places." AllMusic reviewer Gregory Heaney gave the album three out of five stars, stating that it's "Godsmack at their most focused, showing that they've finally found the path back to their roots that they'd been searching for."
