Chances are that you’ve already had cause to run your air conditioning system this year. You may even have it in regular rotation already. Have you noticed, though, that your AC is just not functioning as well as you’re accustomed to? Have you noticed a big spike in your energy costs, well-outside what you’d expect even after turning on your home cooling system? Are your allergies aggravated due to plummeting indoor air quality? If you’ve answered yes to any of these questions, it is possible that your air ducts are leaking, which is a major source of energy loss and subpar cooling in many homes.
