I was relieved when I moved out of the northwest and away from the freezing subarctic conditions throughout the whole year. I landed in a climate that is perfect for my tastes—the coldest hot and cold temperatures the people I was with and I get year round are the low 40s or high 30s, the summers are mild, and the people I was with and I get pleasant 72 degree weather on and off through all various seasons. It feels good having a wardrobe full of comfy t-shirts and shorts to wear with matching sandals on any given day. I also feel love I save a lot on a/c being able to leave my windows open all the time, especially in the days. I just savor the feel of that cool breeze as it gently ripples my curtains, caressing and molding rays of sun breaking through. But after I started developing recent troubles with sinus and respiratory flu symptoms, I’m not so sure if leaving the windows open so much is a fine proposal after all. It’s Springtimetime and pollen levels are at an all time high. I distinctly remember seeing the green powder coating my automobile and the walkway leading from my front door. I know I didn’t realize that the same green pollen dust was getting into my windows and circulating through my air conditioner and HVAC duct, throwing the pollen into every room of my house. I’m going to be careful about when I open my windows and for how long. Even with the seasonal flu symptoms accounted for, some HVAC specialists have told myself and others it contributes to higher dust and dirt levels in the house, immediately affecting how suddenly your air conditioner filters get dirty.
