We are about to transition into spring, then summer, so you want to make sure your air conditioner is going to work properly the first time you turn it on. One of the best tips is to change your air conditioner filter at least four times a year. This assures clean air and saves energy and money. Air conditioners are designed for about a 20-degree change in temperature, so 100-degree air will be cooled to about 80 degrees. It is fairly common for an air conditioner to ice up. If this happens, turn off your compressor and switch your thermostat over to a fan. As the ice melts, make sure there is proper drainage and call a professional. Dirty coils to poorly designed ductwork can restrict airflow. Consider having your cooling system serviced before hot weather arrives. De Hart Plumbing can get the job done for you.
