The time is fast approaching that you are going to start to switch off the heater and turn on the AC unit. The warm weather of the spring and summer are a great time to spend outdoors and enjoying the weather but it is also a time that your home can become too warm to be comfortable. The air conditioning unit cools the home and makes it so that you can be comfortable and enjoy your time inside your home. When you go to start using the AC and find that it is not working well it can be frustrating and it can lead to repairs needing to be done. One of the areas that could be of concern but can be repaired by calling an air conditioning company is to recharge the unit with Freon or refrigerant.
Air Supply Heating & Air Conditioning lists what signs that you can look for to determine if you need to have your AC unit recharged.
Air Conditioner Takes Too Long to Cool House: This is a sign that you may be low or out of refrigerant. If the air conditioning unit kicks on and air is circulating through your home but it is not cooling as fast as it normally does, it can be a sign that you need your AC unit recharged. The refrigerant or Freon is what will take the heat out of your home and allow the cool air to circulate and bring the temperature up the desired degree. When it is low the air will cool much slower because the heat is not be soaked up.
Home AC Vents Not Blowing Cold Air: Another way that you can tell that your air conditioning unit is low on refrigerant is by checking the temperature of the air that is coming out of each vent. If you go over and place your hand near the vent the air that is coming out should be cool. If the air is still warm or the actual temperature of the room itself then you could be low on Freon or refrigerant. That is why the house cools much slower.
Ice Buildup on Outside Lines of Air Conditioner: You can look at your unit that is usually outside the home and can be identified by a large fan that is part of the unit. If you notice that the copper refrigerant lines are coated in a layer of ice you could be low on refrigerant. The refrigerant is so low that it cannot make its way all the way through the line and will come backwards. That can lead the line freezing and causing some ice to buildup.
