Causes For An Air Conditioner Blowing Hot Air Aberdeen NJ

Your air conditioner works hard to help you fight off the summer heat. As the summer moves forward, many homeowners deal with malfunctioning air conditioners that require repairs. This situation is the reason why summertime is the busiest season for HVAC technicians.

One of the most common concerns that we receive is an A/C blowing hot air. Luckily, this article will discuss some of the causes to help you troubleshoot this AC issue.

Wrong Temperature On Your Thermostat

Make sure that your cooling system isn’t on ‘heat.’ Change it back to ‘cool’ if it isn’t on that setting yet. Wait for a few minutes to see if your AC starts blowing cold air.

Also, check if the thermostat is set to ‘on’ or ‘auto.’ If your AC on to ‘auto,’ it means your fan runs continuously even when your system isn’t heating or cooling the air. The ‘auto’ setting means that the fan is only running when it is distributing the conditioned air throughout your home. The ‘auto’ setting is more energy-efficient and ensures that you get cool air when you need it.

Faulty Circuit Breaker

The next thing you need to do is ensure that your AC is receiving sufficient power. Check your electric panel. Because HVAC units require a lot of power to operate, the circuit breaker may automatically shut off when there’s too much power demand.

Look if there is a tripped breaker or a blown a fuse. To turn the power back, flip the breaker switch completely off, and then flip it back on. However, you will need to replace it if you blew a fuse. If you are unsure of what to do, it is best to contact an HVAC technician or an electrician.

Low Refrigerant

Your system needs to have the correct refrigerant charge for it to work correctly. Loose joints, a worn service valve, and poor assembly can cause a low refrigerant charge.

Solving your low refrigerant issue isn’t as simple as adding more refrigerant in your system. You need to call an EPA-certified HVAC technician quickly. NATE certified professionals have the right tools and qualifications to fix all of your refrigerant issues as soon as possible.

Broken Compressor

The compressor’s critical role in your AC is to make your refrigerant absorb heat by compressing it into a high-pressure gas. A broken compressor can be the reason why your AC is blowing hot air.

When your compressor breaks, the refrigerant cannot absorb high amounts of heat, and this prevents the air from being cooled by the outdoor coils. Screeching or grinding noise usually accompany a broken compressor. To verify if you have a broken compressor, you should call a professional technician.

Dirty Condenser

The outdoor unit, also known as the condenser, is where the heat from your indoor unit is dispersed. Removing the warm air is essential to cool your home. For your condenser unit to effectively remove the heat, the outdoor unit’s cooling fans and the unit itself need to be free from debris.

If the system is incapable of producing cold air, it might be because debris and other obstructions are limiting the air flow. Clear all the dust and debris from your outdoor unit. Also, make sure that no plants are growing within two feet around the condenser.
