Have you ever questioned what was wrong with your air conditioning system? Even if you already have it on the lowest temperature, it’s not doing its job to provide you the cooling you need at home. The worst part is that you even have to resort to using a fan to help make your room bearable. It’s ironic, isn’t it?
Instead of second guessing or trying to get by with your fans, the best thing you can do is to have your air conditioning unit checked. Without you knowing it, your air conditioning unit may lack refrigerant. In such situations, having a professional air conditioning technician can be a big help in getting your unit working properly once again.
But how do you know for sure that your unit needs more Freon? Especially if you have an older unit, it may be difficult to determine. Here are some of the things that will indicate your air conditioner requires more Freon:
Sign #1: No matter what you do, it won’t cool down.
When your air conditioning system is not functioning properly, it still manages to make your room feel a bit cooler compared to the temperature outside. But if the unit seems to be completely useless, it may require more Freon. If you’ve set the thermostat lower and there doesn’t seem to be any noticeable change in the temperature in the room, your unit may require a refrigerant recharge.
The reason why your air conditioner does not provide a cool temperature when it lacks refrigerant is because it takes heat from the home and sends it outside. If there isn’t enough Freon, the unit is unable to do its job properly.
Sign #2: There is a gurgling or hissing sound.
If you regularly use your air conditioner, you will notice when it starts malfunctioning. When your unit starts producing hissing or gurgling sounds, it could be an indication that there are some problems that need to be addressed. Adding this with a unit that’s not properly cooling the room could be a sign of a leak in the refrigerant.
Your refrigerant system needs to be sealed permanently. However, it is important to know that not all refrigerant leaks produce a hissing or gurgling sound. If it is a small leak, you might not hear anything at all.
Sign #3: Your electricity bill has skyrocketed.
A direct result of turning down the thermostat of your air conditioning system, it will make use of more electricity to do its job. But since you are not getting any cool air at all, it seems to be pointless and just a waste of money.
If your air conditioning unit is running low on refrigerant, it could consume a huge amount of electricity. When you start to notice a higher electricity bill compared to last year, it could be a sign that your unit needs more refrigerant.
Sign #4: There is no cool air blowing out from the registers.
The most obvious indication that your air conditioning is not working right is when you notice that cool air is not produced at the registers. If you have a heat pump, you may think that the problem can also occur in winter since the register air isn’t as warm as a furnace. This doesn’t happen all the time since heat pump cooled air is supposed to feel a bit chilly.
What you have to know is that heat pumps work like a refrigerator. During the summer months, the heat from the home is pulled outside. During winter, the heat indoors is also pulled from the outside.
Sign #5: You spot ice on the refrigerant line of the air conditioning unit.
Although you might think that the ice on the refrigerant line is a good sign, it actually isn’t. If your refrigerant is running low, the evaporator coil found in your air conditioner becomes cooler and cooler. This is because little heat is absorbed by the refrigerant indoors. The progressively colder refrigerant keeps cycling around the unit.
If you spot ice on your refrigerant line, it’s important that you switch off the unit quickly. Even though ice is not damaging, its side effects may be. Since your compressor is not equipped to handle colder refrigerant, it could end up damaged. When this happens, it could be pretty expensive on your part.
Once you notice these 5 signs, it is important that you schedule a visit with your local HVAC repairman right away. The sooner you can have Freon recharged, the better your home will be.
