Summer heat has once again come to central Texas. Is your cooling system ready? Air conditioning is not just a luxury here, it’s a necessity. Keeping cool, however, is becoming more and more expensive. Summers seem to begin earlier and last longer, creating more demand. Increased energy consumption stresses the power grid causing brown-outs and black-outs to occur more frequently. New regulations make power production more expensive resulting in higher prices for consumers. As utility costs continue to rise, the need for efficient air conditioning is more important than ever. Fortunately, there are some simple steps that can help you keep your cool this summer.
