If your air conditioner (AC) is not working properly, it may be due to low levels of antifreeze. Antifreeze is a type of fluid that helps keep the temperature within your AC system regulated. Without enough antifreeze, your AC will struggle to cool down and can eventually stop working altogether. Low antifreeze levels can occur for a variety of reasons including leaks in the system or simply because it needs refilling after use over time. The good news is that you can easily check and top off the fluids yourself or hire an HVAC technician to do so if needed. Checking the level of antifreeze regularly and topping it up when necessary is important, as otherwise your AC could stop functioning entirely leaving you without cooling relief during hot summer days!
