Before you even call a technician, you should clean the air vents out in your home. Air vents are meant to catch dust, debris, bacteria, etc. And that’s exactly why they should be cleaned!!
Too many people forget about their air conditioning vents and then their entire home starts to smell and feel dusty. The funny part is that this is such an easy task. An air duct cleaning could be something you need a professional for, but the changing of the air filter and cleaning on that part of the air conditioner is certainly something you can handle. I don’t even think there is an argument to be made against cleaning your air duct and filter, so do it today!
Clean your air conditioner today and at least once per quarter after that. You will find you are spending less money on your air conditioner and will notice your home is cleaner!
