The Steelmen won only one of their opening 10 matches in all competitions at Fir Park this season, but all thoughts of poor home form causing them problems have been alleviated in recent games.
They have scored 15 goals in their last five Scottish Premier League games, collecting 13 points, to leave McCall a happy man as his side moved past Caley into second place behind runaway leaders Celtic.
"That's us in the last five (home) games we have averaged three goals," McCall said. "You were asking, and had every right to ask, coming into December about our home form. Thankfully just like last season we have turned it round.
"We are not only winning games but we would like to think we are entertaining as well and scoring goals to boot.
"I thought it would be an open game, we always have good games against Inverness. They played their part first half and knocked it about well.
"I thought we always carried a threat. I think the difference was clinical finishing.
"Obviously we got lucky with the first one. It was a good move to get Henrik (Ojamaa) in down the side but he has screwed his shot and big Michael is there.
"But the second and third goals were class. Lawsy (Nicky Law) I thought all day was outstanding, great skill and a good goal and our third was a terrific strike, which he is capable of. He is technically very good."
