We got central air about a year ago, and LOVE IT! We find ourselves using it frequently to keep the air in the house feeling 'fresh' and to cut through the humidity at times. We paid $3400 installed, for a ~2000 sq ft house. VERY good investment for the comfort it brings
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
