What To Do If Your AC Is Not Cooling?

Have you ever had your air conditioner spew hot air instead of cooling your room? This condition can irritate us, and therefore air conditioner maintenance in Phoenix is vital, especially during the hot summer months. Your air conditioner may not be working correctly for a variety of reasons. These are the six most prevalent reasons why your air conditioner isn’t cooling your room:

Reasons Why Your AC Is Not Cooling

  • Unclean air filter

Unclean air filters are the most typical cause of your split and window AC not cooling. If the AC filter is dirty or blocked with dust and grime, it can cause various issues. It has the potential to obstruct the thermostat’s correct operation. 

Dirt in the AC filters obstructs the flow of cool and warm air via the ducts. It’s also possible that the evaporator coil will freeze, preventing cool air from exiting the outlet. The solution is to get your air filters renewed by air conditioner maintenance in Phoenix providers.

  • Compressor failure 

The compressor controls refrigerant flow between the evaporator and the condenser in an air conditioning system. As a result, a broken condenser cannot adequately chill the air. It is essential to hire an experienced specialist to help you with this.

  • Tampered heat pump

A heat pump looks similar to an air conditioner, but it has extra components that allow it to cool and heat your home. In terms of ventilation, it’s identical to an air conditioner’s condenser device, and it’s prone to the same issues like dirty, clogged coils, freezing coils, refrigerant leaks, compressor malfunctions, and so on. If your heat pump system isn’t cooling, check the thermostat settings, the air filter, and the condenser unit for any previously mentioned issues.

  • Incorrect setting of the thermostat 

Check the thermostat if your split or window air conditioner isn’t cooling. If your air conditioner blows cool air first, then warm air, you have a problem. Put the thermostat on auto when presented with a situation like this. When the air is cooled in this way, the fan will only turn on. If it’s turned off, set to heat, or set for the continuous fan, and then switch it back to cooling mode. It is a common reason why your air conditioner isn’t working correctly.

  • Other Common Causes

We sometimes jump to the worst situation. There might be a very simple reason behind the ac malfunction. Here are the list of things you should check –

  • Make sure all of the windows and doors are shut.
  • Check to see if your supply and return vents are open and unblocked.
  • Make sure your thermostat is set to cool and set to a setting below room temperature.
  • Some outdoor systems may even have a red reset button near the refrigerant line. Try pushing it if you can find it. A quick system reset will sometimes fix the problem.

Regular, scheduled maintenance will increase your air conditioner’s energy efficiency and cooling output. A malfunctioning HVAC system can significantly raise your electricity costs while also failing to keep you cool during the summer. Conducting essential air conditioner maintenance and cleaning your HVAC system can also help you avoid costly repairs and replacements. 


Thus if you face any of the problems mentioned above, contact your nearest air conditioner maintenance Phoenix provider immediately. Their specialists will walk you through a step-by-step process during routine maintenance to ensure that your air conditioner continues to function correctly long after they depart.
