United Technologies (NYSE:UTX) said Wednesday it managed to elevate its fourth-quarter profits by 12%, surpassing Wall Street’s expectations.

Hartford-based United Tech, which is the world’s largest maker of elevators and air conditioning equipment, said it earned $1.2 billion, or $1.31 a share. A year earlier it earned $1.07 billion, or $1.15 a share. Sales climbed 6% to $14.9 billion.

Analysts had been calling for EPS of $1.29 on $14.75 billion in revenue.

“UTC's fourth quarter results reflect strong sales growth, particularly in the commercial aerospace aftermarket and shorter cycle Carrier businesses," CEO Louis Chenevert said in a statement. “In typical UTC fashion, cash generation was strong in the quarter and throughout the year."

Chenevert also said for that for the first time in the company’s history, all six business units delivered double-digit operating margins for the full year.

In addition to elevators and ventilating equipment, United Tech makes firefighting equipment, security systems, aircraft engines and military helicopters.

United Tech, which is a member of the Dow Jones Industrial Average, affirmed its 2011 guidance, saying it sees EPS of $5.05 to $5.35. The midpoint of that range, $5.20, would trail the Street’s view of $5.33.

The company also projected 2011 sales of $56 billion to $57 billion, compared with forecasts from analysts for $56.93 billion.

Shares of United Tech slipped 0.04% to $81.70 ahead of Wednesday’s open. The stock has rallied almost 20% over the past year.
