You depend on your air conditioning system to keep your home nice and cool during the warm summer months. But, if your system doesn't have an adequate supply of refrigerant, it isn't going to be able to do its job properly. Not only will this leave you uncomfortable and hot, but it can also cause your home to be quite humid. Low refrigerant levels can end up damaging your air conditioning system, which is why it is more important than ever that you make sure your system has what it needs to survive. To help you identify whether your system is low on refrigerant or not, look for one of these telltale signs.
The house seems to take forever to get to the desired temperature.
If you noticed that your air conditioning system is taking far longer than normal to reach its desired temperature, it might be because the unit needs more Freon. The refrigerant takes all of the hot air out of your home and absorbs it. If there isn't an adequate supply of it in the unit, there is no way it can absorb enough of the hot air to get your home nice and cool.
The supply vent seems to be blowing out warm air.
When your system is almost out of Freon, you will end up noticing all of the supply vents pushing out a warm air. Since it isn't blowing out the nice, cold air that you desire, your home will remain warm. Put your hand up to the vents. If you feel the warm air, you need to have someone come out and add more Freon to the system for you.
There is a bunch of ice built up on your coolant lines.
Take a look outside at the air conditioning system. Do you see a bunch of ice on the refrigerant line? if so, your refrigerant might be to blame. When your unit doesn't have enough refrigerant, the evaporator coil ends up getting too cold. This ends up causing the liquid refrigerant to get pushed back into the refrigerant line. In turn, the moisture that was once on the line will end up freezing.
If you noticed any of these things going on with your system, you need to have a licensed air conditioning specialist (such as one from Enright and Sons) come out and add Freon to the system for you. It will save you a lot of hassles and headaches down the line.
