2003 Volvo XC70 Condensation puddle under car

2003 Volvo XC70 All Wheel Drive Automatic 99000 miles

I drive approximately 25 miles to work every day. When I come to my car to go home I've noticed a large puddle of water underneath it. It's wider than the car. The dealer says it's just condensation. But should there be so much? I've also noticed that the climate control system doesn't maintain the temp inside the car after about 25 minutes. Could the two be related. What needs to be fixed here?
