Why Is My AC Blowing Hot Air? Reliable Tips You Can Use

February 20, 2018

A broken AC unit that is blowing hot air is sure to throw a wrench in your summer fun. We rely on our air conditioning systems to provide effective relief from the summer heat and humidity.
Many people also rely on AC units for their health, especially older homeowners. If your air conditioning system is blowing hot air, there are a few problems it could be. Here are some of the most common issues that cause hot air to blow from your air conditioner:

Low Refrigerant

The refrigerant is a fluid that is used in AC systems to provide the cooling power. All air conditioners require a certain level of refrigerant to operate properly. If the refrigerant in your AC is low, you will most certainly experience reduced cooling power, and even, hot air blowing from the register.

One tip that many homeowners ignore is the fact that low refrigerant is a sign of a refrigerant leak. In many cases, homeowners will simply add more fluid and call it a day. However, if you do not address the leak, the problem will persist.

Some of the most common causes of refrigerant leaks include manufacturer’s defects, accidents from past work, and incorrect installations, which is why it is always important to work with a licensed professional who knows what they are doing.

Frozen Components

If vital components such as the evaporator coil become damaged or contaminated, they could freeze, causing a snowball effect of issues throughout the entire AC system. Inner AC components can become contaminated by dust and debris with a dirty or clogged air filter.

If your evaporator coil has become contaminated and frozen, here are some of the signs you will notice:

Increased humidity in your home.
An AC that turns on and off all the time without changing the temperature.
Warm air blowing from the registers.
A noisy condenser unit that is compensating for the frozen coil.

Depending on the severity of the problem, we may be able to simply thaw and clean the coil, or we may recommend a new coil replacement if the damage is extensive.

AC Breaker Problems

If your air conditioner is always blowing the AC breaker, it’s a pretty clear sign that something is wrong. The breaker panel is in charge of throttling the electricity in your home. If it senses an overload, the breaker will trip, protecting your family and appliances from damage.

An AC breaker that constantly trips is a sign that the air conditioner is using too much electricity. This could happen for a variety of reasons including:

The AC is straining to work efficiently because of a clogged air filter, low refrigerant, or another efficiency issue.
The unit was not installed correctly, and the AC and breaker panel are not compatible.

Regardless of the cause of the issue, a licensed cooling specialist can assess the situation and offer comprehensive options that will solve the problem for good.
