A leak in AC refrigerant can cost you in terms of comfort and dollars by increasing your electric bills.
While we often enjoy warm summer days, we don’t want that heat creeping into our home. Have you noticed warm air or lower than normal air coming out of your system? You may have noticed that there is water on the floor by your HVAC unit or that ice has formed on the evaporator coils. If so, these are definite signs of an AC refrigerant leak.
When there is a reduction of refrigerant in your unit, this is not a normal part of the operation of your AC system. When a unit is running properly it circulates and maintains the same amount of refrigerant at all times.
5 Signs of a Refrigerant Leak
There are a number of symptoms and possible causes of an AC refrigerant leak:
- Your indoor unit is making a hissing sound – A refrigerant leak is cause by cracks or holes in the coils that circulate the refrigerant. A hissing sound can indicate other problems too but a refrigerant leak can be one of them. If the hole or crack is large, there may be a gurgling sound instead.
- Loss of cooling power – Refrigerant is very important in the cooling process. It’s job is to absorb the heat from you house and release it outside. If refrigerant levels are low, it will take longer to cool your home.
- Warm air coming from your registers – if the air coming out of your vents is warm or not a cool as it should be, this can be an indicator of a leak.
- Frozen coils – when refrigerant levels are low, the coil cannot adequately absorb heat. This results in the condensation on the coils to freeze. When this happens, you may notice that that frozen condensation begins to melt and drip onto the ground. It is important to get this issue addressed immediately so that it doesn’t lead to more expensive problems.
- Higher electric bills – when your home gets a little warm, you turn down the thermostat. At first, you may not notice an issue but your utility bill may reflect something different. Look at your bill this year and compare it to last year. If there are inconsistent usage levels, you may have a small AC refrigerant leak that is just gradually causing an issue.
Refrigerant Leak – What Should You Do?
First of all, AC refrigerant leaks can be prevented by having regular HVAC maintenance. Routine service on your HVAC system can prevent costly problems. However, if you notice any of these signs it is best to call an HVAC service company.
Some people may try to fix a small leak themselves by using a sealant. But this temporary solution can cause more problems than it may fix. Sealants can actually cause blockages, which will only cause more damage.
