Chester have beaten Kidderminster at the Lookers Vauxhall Stadium with two goals from Hannah and a second half effort from Rooney separtating the two sides after falling behind to a Kelvin Langmead effort.
Steve Burr made two changes from the side that was defeated at Forest Green Rovers as John Rooney returned from suspension in place of Jordan Chapell and Ben Heneghan came back in for Michael Kay.
Chester started brightly as Craig Mahon's mazy run saw him beat three before forcing Harriers 'keeper Dean Snedker into a routine save.
Despite enjoying the majority of the play Kidderminster were happy to soak up pressure and hit the Blues on the break and nearly took the lead through Jordan Murphy, who created a yard of space before firing just wide of Jon Worsnop's post.
After quarter of an hour Ross Hannah had a golden opportunity to put Chester ahead. Johnny Hunt saw his shot parried out to the Blues striker but his instinctive reaction effort deflected the wrong side of the post.
It was the visitors who opened the scoring though as Ben Whitfield's free kick was squared by Matthew Barnes-Homer and Kelvin Langmead found the back of the net from close range five minutes before the break.
Chester thought they should have had a penalty a minute later as James Roberts showed some excellent control to lift the ball over his man before cutting back and appearing to have his legs taken from him as he turned, it didn't deter the Blues though who equalised moments later. Craig Mahon's run found James Roberts and his cross was neatly converted by Hannah.
Hannah had the ball in the net again before half time as he reacted quickest to Luke George's powerful effort that Dean Snedker could only parry, this time the official raised his flag so the goal wouldn't stand.
At the start of the second half Chester picked up where they'd left off and Ross Hannah picked the pocket of a Kidderminster defender before squaring for Rooney, who coolly slotted home from the edge of the penalty area.
Confidence was clearly flowing in the hosts and it almost lead to a wonderful goal as Ian Sharps, Johnny Hunt, Craig Mahon and Ross Hannah all linked up in a flowing move before left back Hunt couldn't get his shot away.
The Blues fans got a chance to see new signing, Calum Dyson, make his debut on loan for the club and he almost made an immediate impact as he found Jordan Chapell, but the winger couldn't keep his effort on target.
Chester's pressure paid off and it was Rooney and Hannah again involved, this time with reversed roles as Rooney saw a shot blocked and parried into the path of Hannah who applied the finish at the back post.
Tom Shaw almost added a fourth as he received a lovely backheel from Dyson but couldn't keep his shot underneath the crossbar.
