Getting home to a dysfunctional air conditioner can be frustrating. A refrigerant, normally Freon, is an important part of your air conditioning unit. If your system is low on Freon, it can have a huge impact on your comfort as well as electricity bills.
Being able to tell if there’s a leak can be tricky, which is why you need to have your AC maintained to prevent leaks. Here are some signs that your AC could be low on Freon.
Ice on Refrigerant Line
Low refrigerant in your air conditioner means low pressure, which in turn translates to low temperatures, eventually freezing the evaporator coil, explains Legacy Heating & Air. A frozen evaporator coil causes Freon to leak through the refrigerant line, thus causing the surrounding air to freeze. If you notice ice on your refrigerant line, it’s best to call air conditioning repair to fix the problem.
High Electricity Bills
If your AC unit is low on Freon, it adds pressure to the compressor and runs longer. This means that the more time it takes to run, the higher your utility bills will be.
Takes Long to Cool
A sudden change in how your AC unit works could be an indication of low levels of refrigerant. For the air conditioner to cool your air, it needs a coolant and if it’s low, then your AC is likely to blow lukewarm or warm air. Other things could also cause this including issues with your compressor, accumulated dirt on the outside unit or settings on your thermostat.
If you notice that your AC is making a bubbling or a hissing sound, it could be a bad refrigerant leak.
If you’ve witnessed the above signs, it’s critical to call in an AC technician for a diagnostic check. In case of any leaks, the professional will fix them before adding any refrigerant.
