The west London club stepped out of the bottom three of the Barclays Premier League last weekend with a 2-0 victory over Burnley, their third win in four matches at Loftus Road.
But they have the worst away record in the competition having failed to secure even a draw in seven outings ahead of Monday night's visit to Everton.
"Our home form has been excellent and that's the key
We've had some real crunch games, real six pointers, beating Aston Villa, Leicester and Burnley at home," Redknapp said.
"We're in good form at home and I couldn't be more pleased with how we're playing.
"The key now is improving our away form, although there has been a big improvement in performances
Now we need to turn that improvement into points.
"We've got a difficult game against one of the best teams in the Premier League in Everton
It will be tough, but we have to try and find a way to get some points."
Everton have endured a mixed campaign and sit 12th, but Redknapp refuses to read too much into their position.
"It's been one of those seasons because normally you can pick the teams who would be in the top seven at this stage," he said.
"But West Ham and Southampton have been fantastic, while Everton, Liverpool and Tottenham haven't found the form we all thought they would
But there's a long way to go yet."
Redknapp has denied making recent approaches for former Tottenham strikers Robbie Keane and Jermain Defoe, who both play in Major League Soccer, but is interested in strengthening in January.
"It's going to be tight at the bottom and we'll all be looking to improve our squads if we can," he said.
"If we can find a couple of players who can make bit of a difference, we'll do that
But they have to be the right players
If we get them in, then great."
