What To Do If AC Is Not Blowing Cold Air

Instant relief from the blistering heat of a hot summer day is essential for your health and safety. However, when your air conditioner is experiencing problems, and you notice the AC not blowing cold air, your home can get uncomfortably hot quickly.


Fortunately, Premier Systems provides fast AC repair services in Bozeman, MT, to keep you and your family cool and comfortable. Here's what to do if you notice your AC not blowing cold air:


Assessing Your Air Conditioner

Thoroughly examining your unit is a wise first step when your AC is not blowing cold air. Learning the cause of your air conditioner's breakdown can help you find the best potential solution. There are many common reasons for air conditioners that aren't cooling, such as:


  • Clogged drain
  • Clogged filter
  • Dirty compressor
  • Ice buildup
  • Condensate airflow switch
  • Low refrigerant levels
  • Power problems
  • Thermostat issues


Common Air Conditioner Problems

You can fix many minor AC problems without the assistance of a professional HVAC company. However, you should not address more severe issues or anything requiring the expertise of an air conditioning expert without contacting Premier Systems first. 


Power Problems

Check if you plugged your AC into the outlet. It may sound simple, but it is the first thing you should do. It happens more often than you think, but doing so brings you closer to determining your AC problem. 


Air conditioners sometimes have an overload switch and automatically shut down to prevent danger, so check yours as a next step. You may have electrical problems such as a tripped breaker or faulty fuse if the outlet and electrical cord are working fine. You may need an electrician to fix the issue, but having an HVAC specialist look at the situation is a wise first place to start. 


Built-Up Ice

Since your AC is responsible for cooling the air, it only makes sense that ice can build up. Numerous reasons can explain why you would notice a large amount of ice on your outdoor unit. The problem could be dirty filters or low levels of refrigerant. 


You can try to melt the ice off by only turning on the AC fan. Clean the filter, condenser, and evaporator coil to see if the issue is due to poor airflow. Once you've done these tricks, check your refrigerant levels and fill them if necessary. 


Clogged Drain

Air conditioners remove excess moisture in the air and carry it out through a drain or hose. It can become clogged if dirt, debris, and algae growth accumulate too much, and you will need to clean it out. Sometimes, a mild bleach solution can effectively clean the hose or drain and fix it if your AC is not blowing cold air.


A thorough cleaning can prevent a water backup in your home, but the fail-safe in your unit detects when this is an issue and shuts down for safety.


Clogged Filter

You can expect your AC filter to get dirty over time. A clogged one can cause the AC to shut down to avoid damage and an overheated motor. Examine your filter and clean or replace it based on its condition. A clogged filter can also limit airflow and prevent your AC from cooling the air, but periodically checking and replacing your filter can help.


Dirty Air Compressor

An air compressor is the component of your air conditioning system you would find outside. It can accumulate leaves, dirt, and debris and become clogged from the elements, affecting your AC's performance. While you can clean the unit frequently, consulting a professional (like Premier Systems) can ensure the best possible cleaning and maintenance if applicable. 


When you contact us for an air compressor cleaning, you can receive immediate repairs from a licensed HVAC technician. Always turn off your AC before cleaning if you decide to do the job yourself. You can also purchase a cover to protect the compressor during the winter.


Low Refrigerant Levels

A refrigerant leak can slowly cause your levels to decline. Many people think that refrigerant or coolant expires, but it does not.


You will need someone to check your lines and recharge your system and should not attempt the task yourself. The chemicals, multiple factors involved, and knowledge of the air conditioner make hiring a professional necessary. The job will be done correctly by experienced and licensed technicians.


Worn-Out Parts

The age of your system and operation can affect performance, so you might find it more beneficial to upgrade your AC. It may be more trouble than it is worth to continue with repairs when a smart upgrade could save you time, stress, and money.


When you notice your AC often needs costly repairs, has frequent problems, and is at least ten years old, you should talk to Premier Systems about replacing it with a better and newer one.


Thermostat Issues

Your thermostat's setting may be at the wrong temperature. There also might be a wiring or connection problem. 


Switch the thermostat's dial down to the lowest possible setting. It may trip the unit and get it running again. If the AC is still not blowing cold air, check that the thermostat's connection is correct and that any batteries are working (if applicable).
