4 Reasons Your AC Isn’t Blowing Cold Air & How to Fix it
Jan 3, 2023
Your air conditioning system should be working at peak efficiency all year round. So if your AC isn’t blowing cold air, you have a problem. A poorly performing air conditioner can lead to serious problems such as mold growth and increased energy consumption as temperatures rise.
Why is your air conditioner not blowing cold air? Why would an air conditioner not cool enough, even when it seems to be working? Good questions. However, there’s no single answer. Instead, several things can reduce or impair your AC’s ability to generate cold and push that cold through your ducts. For example, the compressor could fail, causing the unit to stop working altogether. In addition, the condenser coil could become clogged, preventing cool air from flowing through the system. These common problems can cause your air conditioner to not blow cold air.
To find out what’s causing your unit to struggle, we recommend contacting a professional HVAC technician like Simpson Sheet Metal Heating & Air Conditioning. We will thoroughly inspect and identify the root cause of your problems.
We want to help you learn more about some common issues you might be having with why your air conditioner isn’t blowing cold air. Let’s take a closer look.
First Step: Check Your Circuit Breaker
The best first step you can take is to check your breaker box. Your AC runs on electricity, like everything else, so you might not get cold air if the breaker is thrown. Your breakers can also be thrown by various causes, from neighborhood power outages to plugging the vacuum into the wrong outlet. Every house is wired differently, and you never know what will throw the AC breaker. Your AC works hard in the hot summer months, which can also throw its breaker.
So give that breaker a toggle just to be sure.
4 Reason To Look Into
Aside from the circuit breaker, there are four leading reasons to consider if your air conditioner is not blowing cold air.
Air Duct Leak
One of the leading causes of not enough cold air is a duct leak. This means your precious cold air escapes into the uninsulated areas between your walls or your attic. A duct leak should be repaired by professionals who understand the unique sheet metal construction that is at-home air ducts. You should regain full power over your home’s airflow by re-sealing your ducts – hot or cold.
Dirty Air Filter
A dirty air filter prevents fresh air from getting to your AC, but it also prevents air in general from circulating in your AC. This means slower air flow and insufficient air pressure to distribute the cold to each room. Dirty air filters can also lead to dust buildup on the coolant coils, preventing cold from reaching the circulating air.
The refrigerant is a coolant fluid that expands and contracts in the pipe, helping to grab or deposit hot or cold. However, if your refrigerant fluid leaks, this is not only a chemical hazard but can also weaken the cooling power of your entire HVAC system.
Dirty Evaporator Coils
Dirty evaporator coils coated in a blanket of dust. This traps cold with the coils and prevents air from reaching that cold. Dirty evaporator coils eventually become ice formations due to the unique way that temperature occurs inside your AC unit, but clean evaporator coils will save you time and money.
