Everyone loves spring.Everything is new again, time to dust off the grime from winter. But wait, winter has just arrived. Most people do not realize that the wintertime is when the house is closed up and the fresh air is not coming around the computer like it does during the warmer months. Dust buildup is deadly to your system. You need to make sure your system is operating at peak cooling potential. My advice is to have your system professionally cleaned at least twice a year. And with the holidays approaching, the last thing you need is another bill to pay.
