Chinese evergreen brown spots or brown tips? They are different problems.
Where the brown is tells you what caused it. Spots in the middle of the leaf are about cold, sun or disease. Brown tips and margins are about the water. It matters, because the fixes are completely different.

Is it your water?
The browning is at the tips and along the edges, not in the middle of the leaf.
The plant is otherwise full, upright and putting out new leaves.
You water from a city tap, and other sensitive plants in the house have brown tips.
Two of three and it is the water:
Reading the leaf
Brown tips and edges are fluoride and salt burn. Aglaonemas are in the same sensitive group as dracaenas and spider plants.
Brown or black spots with a yellow halo are leaf spot disease, usually from water sitting on the leaves in cool conditions. Remove the affected leaves and water the soil, not the foliage.
Large tan or bleached patches are sunburn from direct sun.
Dark, water-soaked patches after a cold night are chill damage. These plants dislike anything below about 60°F.

When it is not the water
If the brown is in spots rather than at the tips, changing the water will not help. Deal with cold, sun or disease first.
