Though you should have had your A/C checked around March, you may be
able to increase your efficiency by adding some insulation to your
attic. Blown in insulation can be relatively cheap especially since it's
done for you. If it's below 6 inches thick, you may want to add another
6" to 12" of insulation to your attic. Also, if you think that it's not
enough, what about wall-injection. A bit costly, but it'll definitely
decrease the work on your A/C and cool the house down especially during
those unbearable months. Other things to consider may be attic vents and
exhaust fans, though these are matters of opinion. Maybe a ridge vent.
A wha . . .? Here's a recent conversation on
