There are other reasons than spraying to neuter your cat:
•Neutered cats will not be subject to testicular cancer
•Neutered cats will not likely develop "stud tail," caused by overactive glands in the tail
•Neutered cats have a decreased risk of mammary cancer
•Neutered cats are less allergenic
He is responding to the urges he feels and probably smells via the windows or a/c vents that there are females in heat and he wants out to make babies.
Male cats live longer and are healthier if they have been neutered. Get him to the vet and and enjoy his new attitude.

YES!
Neutering provides major health benefits for your male.
Besides preventing unwanted litters, neutering your male companion prevents testicular cancer, if done before six months of age.
Your male cat won't want to roam away from home.
An intact male will do just about anything to find a mate! That includes digging his way under the fence and making like Houdini to escape from the house. And once he's free to roam, he risks injury in traffic and fights with other males.
Neutered cats focus their attention on their human families. On the other hand, unneutered cats may mark their territory by spraying strong-smelling urine all over the house. Many aggression problems can be avoided by early neutering.
Neutering will NOT make your pet fat.
Don’t use that old excuse! Lack of exercise and overfeeding will cause your pet to pack on the extra pounds—not neutering. Your pet will remain fit and trim as long as you continue to provide exercise and monitor food intake.
It is highly cost-effective.
The cost of your cat's neuter surgery is a lot less than the cost of having and caring for a litter. It also beats the cost of treatment when your unneutered tom escapes and gets into fights with the neighborhood stray!
Neutering your pet is good for the community.
Stray animals pose a real problem in many parts of the country. They can prey on wildlife, cause car accidents, damage the local fauna and frighten children. Neutering packs a powerful punch in reducing the number of animals on the streets.
Neutering helps fight pet overpopulation.
Every year, millions of cats and dogs of all ages and breeds are euthanized or suffer as strays. These high numbers are the result of unplanned litters that could have been prevented by neutering.
