AC Repair Jackson NJ: Causes Of An AC That Blows Warm Air

Fortunately, an air conditioning unit that blows hot air is one of the most common AC repairs. Many factors can cause this. In this article, we will cover some of the reasons to help you troubleshoot your AC system issues.

Wrong Temperature On Your Thermostat

If that doesn’t do the trick, you also need to check if the thermostat is set to ‘on’ instead of ‘auto.’ When your thermostat is set to ‘on,’ that means the fan is blowing even if your HVAC system isn’t cooling or heating the room. Use the ‘auto’ setting instead to keep this from happening.

Broken HVAC: Faulty Circuit Breaker

As common sense as this may seem, make sure that your A/C has power. You can do this by checking the electrical panel that is supplying the power on your HVAC system. A tripped circuit might cause the malfunction, or the AC blew a fuse.

HVAC units require a lot of power to run. As a safety precaution, the circuit breaker may shut down automatically when there is too much power demand. Contact a professional HVAC contractor and have your A/C checked immediately when this happens.

HVAC Refrigerant Leaks And Issues

low refrigerantWhen an AC blows warm air, it could have refrigerant issues. The refrigerant is the cooling chemical blend used in your AC’s refrigeration cycle. An AC does not lose any refrigerant during this cycle. However, from time to time, an air conditioner has a refrigerant leak, where the coolant loses its charge, and the AC is unable to cool your home correctly.

A few factors such as loose joints or poor assembly can cause refrigerant issues. Lack of proper maintenance also leads to refrigerant leaks. Even if your air conditioning unit has a pinhole-sized leak, it can still affect your AC’s overall functionality. Because your system is losing refrigerant, it won’t be able to sustain the refrigerant flow. In turn, your AC won’t be able to cool your home. Not only that, but a low refrigerant charge can also cause the compressor motor to overheat.

Remember, you need to fix a problem like this immediately. It can lead to severe damage to the point where your unit is unrepairable. Also, the EPA has a rule in place that states that homeowners must repair refrigerant leaks within 30 days. You need to contact a professional to fix this problem. Search for “AC repair near me” and find the most reputable HVAC company in your area. When you need an HVAC repair, you only want to work with the best. Your comfort and energy costs depend on it.

A repair for a situation like this is not as simple as adding more refrigerant in your AC system. A trusted HVAC technician should fix the leak, test the repair, and charge the system with the correct amount of refrigerant.

Avoid Permanently Damaging Your AC Compressor

Your AC’s refrigerant charge must match the manufacturer’s specification exactly. If your air conditioner is overcharged, you run the risk of permanently damaging the A/C’s compressor. The compressor is one of the vital components of your AC. Its primary responsibility is making the refrigerant absorb heat.

If your unit has too much refrigerant, it will accumulate inside the compressor. The coolant could then overflow and damage the compressor’s mechanical components. This situation might eventually lead to the compressor completely breaking. When dealing with a broken compressor, the refrigerant is unable to absorb high amounts of heat. This situation means that the cooling function of your AC is negated.

Dirty Condenser Means Ineffective Cooling

outdoor AC condenserAnother central component of your AC unit is the condenser. It is the outdoor unit made up of a compressor, cooling fins and tubes, and a fan. However, when your condenser gets dirty, the process of heat transfer that happens with your refrigerant and the outdoor unit’s immediate surrounding is not as effective. In turn, this might be the cause of the warm air blowing into your home. Make sure that you schedule an annual tune-up to prevent this from happening.

Poor Airflow From Damaged Evaporator Coils

The evaporator coils are the part of your condenser. It is here where the hot air from inside your house travels to, and subsequently, it is released and removed. When plant debris, lint, and other dust particles get stuck in your outdoor evaporator coil, the airflow to your coils gets partially blocked. This situation causes high condenser pressure and inefficiencies such as your air conditioner blowing hot air inside your home.

Restricted Airflow From Poor Cooling Fans

For the cooling fan to work correctly, it needs to be in excellent condition. It needs to be clear of debris and other obstructions that can limit airflow. A restricted airflow translates to interrupted AC functionality. Your air conditioner will be incapable of producing cold air because the airflow that is necessary to cool the refrigerant and dispel the heat from your home is blocked. You need to sweep away the debris that accumulates around your condenser. Moreover, trim any overgrowth that is within two feet around your outdoor unit.
