Freon is the blood of the air conditioning system, and without the right amount, the AC can’t properly cool the house. When your AC has a leak, Freon will leak out, causing the air conditioning system to malfunction, and to restore the unit to proper working condition, you have to add more Freon to the air conditioner.
Wondering how do I know my AC needs Freon? According to air conditioning repair services providers, a malfunctioning AC will give several signs that it’s time to add more refrigerant. Some of these signs include:
Ice or frost forming on the AC
If you spot ice or frost on the air conditioner, it might be a sign that the refrigerant levels are low, and it’s time to add more.
The reason frost will form on your air conditioner is that when the refrigerant levels fall too low, the refrigerant’s temperature will drop below the normal design temperatures, which will eventually cause ice to build up on the evaporator coil and refrigerant lines.
You should note that while ice will form on the AC, this isn’t a conclusive indicator that the Freon levels are low as the frost build-up can be brought about by several other issues such as: dirty air filters, closed vents, and many others.
Hissing or bubbling noise
If your outdoor AC unit is making a hissing or bubbling noise, this might be a sign of the refrigerant escaping from the pipes meaning that the Freon levels are too low.
Have your energy bills been on an upward trend, but you haven’t made any significant changes to your home’s cooling system? You might be having a refrigerant leak.
As mentioned above, the refrigerant is the lifeblood of the AC system, so when there isn’t enough of it, the AC blows warm air over the evaporator coil, which is full of refrigerant. The refrigerant then picks up the heat from the air and carries it where it’s dumped.
When the refrigerant levels are low, the AC can’t get rid of as much heat per cooling cycling, meaning that the unit runs longer and works harder to cool the house. The longer run times mean that you have higher energy bills.
Although the low refrigerant levels will cause your energy bill to shoot, it’s not the only reason for the high bill. The air conditioner can also overwork and have a high-energy bill when:
The AC is old: If your air conditioner is more than 10 years old, it won’t be too efficient, and this will result in a high energy bill at the end of every month.
Wrong AC size: If you have installed an air conditioner that is too small or too large for your home, it will function inefficiently, and this will drive your energy bill high.
Dirty air filter: If you have gone for a long time without cleaning your air filter, the AC will function inefficiently, and this will lead to a high-energy bill.
Warm air blowing from the supply vents
Freon absorbs heat from the air inside the house and transfers it outside. When the refrigerant levels are low, the AC can’t absorb enough heat per cycle, so you have warmer air blowing from the supply vents.
Fixing the low refrigerant level problem
If you suspect that you are having a Freon leak, don’t fix the problem yourself. Instead, get in touch with an AC repair services Oakton provider who will inspect the AC, and if it’s true you have a leak, fix it.
You should be cautious about the contractor you hire as no two contractors are the same. As a rule of thumb, avoid an inexperienced technician.
