Why You Can’t Ignore a Faulty Air Conditioner

An air conditioner blowing warm air doesn’t just affect your comfort. If you don’t take steps to fix the system, it can also impact your health and wallet long-term. Ignoring this issue can have the following effects:

• Increased heat and humidity in your home
• Poor indoor air quality
• Higher energy bills
• Greater risk of HVAC breakdowns

You don’t have to settle for an uncomfortable indoor environment and higher utility costs. Schedule prompt HVAC repairs to uncover the root of the problem. Once technicians pinpoint the cause, they can offer a lasting solution and peace of mind.

Five Reasons Why Your Air Conditioner Isn’t Producing Cool Air

“So, why is my AC blowing warm air?” Unfortunately, there is no one-size-fits-all answer. HVAC technicians have to rule out several possible causes when they inspect the equipment. 

Check out the most common culprits below. 

1. Incorrect Thermostat Settings

Is your AC not cooling? Check your thermostat settings. Some homeowners panic and assume their system is broken, but the real problem lies within their thermostat. 

Accidentally putting the thermostat on “Heat” mode instead of “Cool” can have undesirable effects. You may have even set the temperature too high for your liking, which is why warm air is traveling through the vents. Check your thermostat’s settings before you call for help, as the solution may be right in front of you. 

2. Dirty Air Filters

Your AC troubleshooting shouldn’t stop at checking the thermostat. When was the last time you replaced your HVAC air filter? Inspect the filter and replace it with a new one, if necessary. 

When filters clog with dust and debris, they restrict airflow and force the system to work harder. As a result, any limited air coming through the vents could feel warmer than you’d like. If the problem persists after you change the filter, it’s time to contact a professional for assistance. 

3. Refrigerant Leaks

If you ask an expert, “Why is my AC blowing warm air?” they may tell you that a refrigerant leak is to blame. Air conditioners rely on refrigerant to absorb heat, transfer it outside, and produce cooler air. 

A leak somewhere in your system can impact the heat transfer process. When this happens, the air conditioner is unable to fill your home with cool, comfortable air. Invest in regular HVAC maintenance to check for leaks and let professionals top off your refrigerant supply. 

4. Compressor Malfunctions

The compressor is the heart of central air conditioning systems. If it begins to fail, the equipment can’t initiate a heat transfer. You may need to replace this component every few years, especially if you consistently run your cooling system.

5. Frozen Evaporator Coils

Suppose a technician inspects your equipment and finds a frozen evaporator coil. You ask them, “But why is my AC blowing warm air? Shouldn’t a frozen coil mean it’s cooling properly?”

Evaporator coils can freeze when they become dirty or covered with condensation. You may think that a frosty surface means the air conditioner is exceptional at cooling your home. In reality, frozen coils are unable to transfer heat, leaving your home warm and uncomfortable. 

How To Prevent Warm Air Issues 

Never neglect HVAC maintenance, as this keeps your system working properly and rules out common malfunctions. You should also change your air filters regularly to prevent them from clogging with debris. If you notice any unusual changes in your system’s performance or experience unexplained spikes in your energy bills, it’s in your best interest to schedule an HVAC inspection.
