The refrigerant enables your AC to cool your indoor spaces effectively. It travels through the HVAC system, converting low-pressure gas to a high-pressure liquid. As it does this, it collects heat and releases it as it travels, assisting in cooling air in the rooms in your house. If your AC is not cooling as fast or cold as it used to, it might need a recharge.


In this post, Stone Heating and Air shares three signs that indicate your AC needs a recharge.

1. Leaks

No matter how much your system tries, it won’t be able to cool your home if there are leaks in the pipes. HVAC systems need to be sealed and pressurized at all times. If there are leaks, no amount of refrigerant will keep your system running effectively. Check for greasy films in the interior and exterior areas of your unit. Ice can sometimes be found in evaporator coils if the leaks are extreme.

2. Poor Cooling

An HVAC system that takes a long time to cool indoor spaces might have leaks. If you notice your AC is not cooling as it did before or is blowing out humid air, you should have a professional look at your AC and have it recharged. Poor cooling is often a result of refrigerant leaks. You should also pay attention to any dripping or hissing sounds, especially around the coils and pipes.

3. Higher Utility Costs

If your electricity bills got more expensive for no apparent reason, there’s a good chance you have a refrigerant leak. Without enough refrigerant, your system will strain itself to reach the temperature you’ve set on the thermostat. This continuous effort to cool your home causes the system to use more energy, resulting in higher utility costs.
