Humans are extremely adaptable.  Because can get used to anything, we sometimes get used to problems in our home that could easily be changed to make our homes more comfortable.  Take this test:

• Do you know your furnace is running because you can hear it?
• Do you turn up the sound on your television because you air conditioner is on? 
• Do you notice a dusty smell when your furnace turns on?
• Do you sneeze at home?
• Have you ever noticed a blast of cold air coming from your ducts before you furnace starts?
• Do you feel better in your home or outside?
• Does your furnace or air conditioner turn on and off because it heat or cools your house too quickly?

Sandium designs heating and cooling systems that make your home so comfortable that you may not even notice it is running.  That is the way it should be.
