Top Reasons Your Air Conditioner Blowing Hot Air Danvers MA

When your A/C is blowing hot air, you know that something is wrong with your unit. This article will explore the different issues your AC might have when you find yourself in this situation.

Faulty Electrical Panel

The first thing you need to check is if your unit is receiving power. You can do this by checking the electrical panel. There are many reasons why your circuit breaker might shut off. The most common one is because there is too much power demand and the circuit breaker becomes overloaded.

For a quick fix, see if the breaker tripped or if you have a blown a fuse. For a tripped breaker, you merely need to turn the power back on. To do this, flip the switch completely off before switching it back on. If you have blown a fuse, however, it needs to be replaced.

If your circuit breaker continues shutting down after your A/C runs for a while, then you need call a professional. An expert HVAC technician can tell you why this keeps happening.

Thermostat Setting

Lastly, if your A/C’s fan setting is set to “on,” change it back to “auto.” The “on” setting will cause your AC to blow air even if the air conditioner is not cooling the air. The “auto” setting will make sure that only cool, conditioned air blows inside your home.

The ‘auto’ setting is also more energy efficient than using the ‘on’ setting. Therefore, using the ‘auto’ setting is a great way to reduce your home cooling costs.

Compressor Problems

Another vital cooling component of your AC is the compressor. Your compressor helps your refrigerant in the cooling process. The coolant cannot absorb the heat from your home when your AC has a broken compressor. Consequently, it disrupts the refrigeration cycle, and the air conditioner cannot release cooled, conditioned air in your home.

Also, many air conditioning units have a capacitor that helps start the compressor. If the capacitor fails, then your compressor won’t start. Hence, your AC will only blow warm air. An expert will be able to tell if your capacitor is damaged. Consult with a professional HVAC technician to make sure that the replacement capacitor is the same as the old one.

Refrigerant Issues

Your AC needs to have a full charge of refrigerant. Unfortunately, leaks can happen. Holes, regardless of how small, can cause the coolant to lose charge.

When your AC has a low refrigerant charge, your AC cannot efficiently cool your home. Contact a licensed technician to repair this. A professional has the proper tools and knowledge to deal with refrigerant leaks.

Dirty Outdoor Unit

The condenser has a cooling fan that releases the heat absorbed from inside your home to the air outside.

If dust and other debris block the cooling fan, then the airflow becomes limited. When airflow is obstructed, your AC will be incapable of producing air-conditioned air. Therefore, you need to clear all the debris from your condenser.

Make sure that the surrounding plants are at least two-feet away from the outdoor unit. If that doesn’t do the trick, contact a professional HVAC contractor. An expert will inspect your outdoor unit and clean the evaporator coil and straighten out the cooling fin when necessary.



From what we have discussed above, several factors can affect why your cooling system is suddenly blowing hot air. Your AC might be experiencing compressor or refrigerant issues. A problem with your electrical panel can also cause your AC to malfunction. Whatever the cause, a professional HVAC contractor will be able to assist you.
