Furnace tune-up tips

I have always been a “sun worshiper”  Summer is my favorite season. I like to just sit in the sunshine all day long. I know there are a lot of articles and research out there about skin cancer, however at my age, I don’t care anymore. I just want to feel the warmth of the sun. I have never had any issues before, so I am not worried. This Summer, I rented a really cute beach house. It was such a good find. It came with everything I needed, including a state of the art HVAC system.  Don’t get me wrong, I like the heat of Summer. But, I also like the ability to go inside and cool off after a day of baking outside. This place was my best find to date! The first day was great. I spent all day on the private beach in front of the rental. When I came in I was ready to rest. I took a shower and then lay down for a bit before going out to lunch with some friends. When I woke up, I had the felt flush and had a rash on my arms. I had never experienced anything like it before. I put on some lotion and a light blazer then headed out the door.  When I got home, I went to bed when I woke up the rash was even worse. It had spread throughout my body. Now, I was upset. I went to the local urgent care and the doctor asked if I had an HVAC system at my house. I told him my rental did and he told me I may be allergic to their air filters. I never even knew that was a possibility.
