3 Ways to Tell if Your AC Is Leaking Refrigerant, Columbia, Illinois

Refrigerant, also known by the brand name Freon®, is a necessary feature of an air conditioner, so you never want it to run low during the hot summer months. Since refrigerant runs on a closed system, you don't need regular refills. So, if your levels are low, it’s likely because of a leak. Though this is typically a minor issue, it can quickly lead to discomfort indoors and require AC repairs. Consider the following tips to learn how to recognize a potential leak. 

3 Ways to Tell if You Have an AC Refrigerant Leak

1. Higher Energy Bills

By keeping track of your monthly energy bills, you can tell if there are any dramatic increases in charges without any changes to the thermostat. If the costs have skyrocketed, you might need more refrigerant. The monthly expenses go up because it takes longer to cool the home with low refrigerant; your air conditioner is consuming more energy than it should.

2. Warm Air Flowing From Vents

ac repairsYour air conditioner should always blow cool air. If warm air starts coming out of the vents, you likely have a refrigerant leak. The purpose of the refrigerant is to absorb heat from indoors and transfer it outside, but if the levels are depleted, it cannot do its job. Warm air will blow back into the house, and it will take longer for rooms to cool, even if you adjust the thermostat.

3. Frozen Evaporator Coils

The refrigerant and evaporator coil work in tandem to remove warm air from your home and lower the temperature. However, if there isn’t adequate liquid to circulate through the system, it can cause the coil to freeze. If you notice visible frost on the coil or if it is cold to the touch, contact a qualified HVAC contractor who can assess the situation and make necessary AC repairs.
