Why Do Air Conditioners Freeze Up?

When your air conditioner is running properly, it should be nearly silent and should not have any frost or ice present. However, if you pay attention to your system, you have very likely seen part of it icing up at times. Learn what causes these ice-ups and whether it is something that should concern you with this simple guide provided by in Oak Harbor. How Air Conditioners Work Before digging into what causes air conditioners to freeze, you should understand how they work. Your air conditioner circulates refrigerant between the outdoor condensing unit and the indoor evaporator coil. It cools your home by absorbing the heat from the air moving through your HVAC system and venting it outside. To accomplish this, the system must regulate the pressure of the refrigerant. When the pressure goes down, the refrigerant gets cold. When the pressure increases, the refrigerant gets hot. The refrigerant at the evaporator coil should be low, making it cold and allowing it to absorb the most heat. Then, the compressor increases the pressure, allowing it to effectively transfer the heat to the air moving through the condensing coil. If the pressure cannot be regulated or if the air is not...

Problems That Can Occur From Not Changing an Air Filter

Your AC’s air filter is easy to change. By completing this task periodically, you can help prevent many expensive AC problems. Air filters that become too dirty cause decreased efficiency and airflow in the cooling system. In turn, this may cause additional problems, such as high energy bills, warm air, weak airflow, and poor indoor air quality. High Energy Bills A common problem that occurs when you don’t change the air filter based on the manufacturer’s recommendations is an increase in your energy bill. You don’t want to wait until you receive your energy bill to know your air filter caused efficiency problems in your air conditioner, so remember to always change it on schedule. Warm Air When the air filter becomes clogged, the AC’s compressors may overheat. If your air conditioner begins blowing warm air instead of cold air and you haven’t changed the air filter on schedule, then the compressors have probably overheated. At this point, your AC may still need repair after you change the air filter because overheated compressors can cause damage to the system. Weak Airflow Clogged air filters don’t allow air to freely circulate throughout your cooling system. Aside from causing inefficiency, this can...
