Most Arizona homeowners believe the refrigerant inside their AC unit needs refilled regularly. In reality, you should never need to simply add refrigerant as a maintenance item. Low refrigerant inside your ac unit means there is a leak somewhere that needs to be replaced. Routine maintenance on your HVAC system is recommended to help prevent leaks or to discover them before a larger problem arises. 

What Is Refrigerant? 

Within the realm of your AC system, refrigerant is the cooling agent that creates cool air. The refrigerant is located inside the copper coils within your cooling system and absorbs heat from the air inside your house. 

While the refrigerant absorbs the heat, it transforms into a high-pressure liquid and is moved to the outside unit. Within the outside unit, the refrigerant cools down and transforms back into a low-pressure gas before it is transferred back inside and the cycle repeats. Refrigerant plays a key role in ensuring your home stays cool all summer long.

5 Signs Your AC Unit Is Low On Refrigerant 

  1. Warm Air Blowing – In Arizona, it is very obvious when there is no longer cool air blowing throughout your home. This is also an indication that the refrigerant within your AC unit is running low. Warm air blowing through your vents will also ensure the temperature you set on your thermostat will not be reached. 
  2. High Electricity Bill – Much like when a part is broken, low refrigerant levels require your system to work extra hard to cool your home. Comparing monthly bills may help you identify if you have a problem in your HVAC system and low refrigerant is a common cause of AC unit issues. 
  3. Ice Build Up – A key indicator that your air conditioner is low on refrigerant is ice build up on the refrigerant lines. Be sure to check the evaporator coils, or the copper tubing, as this is the main location for ice to form when there is an issue with your unit. You may also notice water leaking near your furnace or air handler. This is caused by the ice melting. 
  4. Strange Sounds – If you hear strange sounds, such as hissing or bubbling, your air conditioner may be low on refrigerant. The sounds are typically caused by a leak somewhere that will need to be repaired by an experienced HVAC technician. 
  5. System Runs All Day – The job of your AC system is to absorb heat from your indoor air and move it outside. When your unit is low on refrigerant, your system cannot absorb as much heat, which then requires your AC unit to run continuously and not cool your house.

These are the most common signs that your AC unit is low on refrigerant. If you are experiencing any of these, it may be time to call a trained HVAC technician. Handling refrigerant can be dangerous and cause significant damage if it is not handled properly.
