AC Not Working but Not Blowing Cold Air: Possible Causes and Solutions

As temperatures heat up and you’re relying more and more on air conditioning, it’s possible you’ll run into problems. Among the most common issues people have with their AC units is when it’s not working but not blowing cold air. Ask any HVAC professional and they’ll tell you this is a tricky problem to fix. To figure out why your AC isn’t blowing cold air, you’ll need to look at possible causes and solutions.

Low Refrigerant Levels

Refrigerant is a critical component to your air conditioner working properly. Usually, a leaking AC or a unit that’s been improperly installed results in a drop in refrigerant levels. The cold air your AC it produces is created when the liquid refrigerant absorbs heat from the air in your house, then releasing it into the outside area. If it’s working correctly, the liquid should remain at the same level throughout the entire process and last for years. However, if there’s a leak, the liquid won’t move to the outside unit, resulting in no air being cooled. Make sure you call a professional to check the refrigerant levels in your AC and repair any possible leaks.

A Malfunctioning Compressor

The compressor is the beating heart of your AC unit. Without it, the AC wouldn’t have the power to blow out cold air. Improper maintenance can put strain on the compressor, leading to it malfunctioning or even breaking. Other possible causes include overworking the unit or improper installation. Look out for signs such as noises coming from the AC or an increase in energy bills. If any of these occur, it’s wise to call a reliable and experienced repair service.

Frozen Coils

Frozen coils happen when the system goes through serious strain, such as overuse or low refrigerant levels. To repair frozen coils, you’ll need to start by turning off the unit and allowing it to melt. This may take several hours. When you turn the unit back on, it’s important to check continuously for any odd, unsettling noises. If you hear any odd sounds, it’s best to call a repair service immediately. If you don’t, you could risk causing additional damage to the AC unit.

Dirty Filters

The filters of your AC unit are essential for keeping the dust, pollen and other particles out of your home. If they’re left unchecked and unserviced, they can become clogged with dirt and other particulates. This disruption to the airflow can reduce the amount of cold air the unit produces. If you experience your AC not cooling and warm air being blown out, check the filter. It’s advised to change it every three months or more, depending on usage.

Does Your Thermostat Need Calibration?

Occasionally, you may experience your AC not cooling properly due to thermostat misreading and needing a recalibration. If your thermostat isn’t calibrated correctly, it will misread the temperature around it and not be accurate. To take a closer look at this issue, it’s wise to call a technician.

AC Not Working but Not Blowing Cold Air: Preventive Action

Nobody likes it when their air conditioner fails to work properly. Air conditioners, however, can sometimes fail to blow cold air, but still appear to work. This can be a frustrating experience, and to prevent it, it’s important to take preventive action. In California, there are a few recommendations from manufacturers, local appliance companies, and HVAC technicians that can help avoid this issue.

Moreover, ensuring the unit is properly sized for the space it is cooling is also important. An under-sized unit will struggle to cool the space properly and will lead to an inefficient use of power and an uncomfortable environment.

Local Appliance Companies

To ensure a proper installation and prevent the air conditioner from not working but not blowing cold air, local appliance companies recommend having the installation done by a qualified and experienced certified HVAC technician to ensure it’s properly done. Moreover, they also recommend checking and following the instructions provided by the manufacturer, including the specifications on the refrigerant levels, as well as the airflow.

HVAC Technician Recommendations

HVAC technicians also recommend cleaning the drain tubes and checking the condensate in order to prevent any issues due to moisture buildup. Moreover, they also recommend making sure that all thermostat settings are correct and suitable for the environment, as well as making sure the condenser unit is regularly maintained. Additionally, it is important that all air vents in the home are clear and not blocked, as well as checking for any leaks in the ductwork that might cause a decrease in efficiency.

Overall, there are a few recommendations from manufacturers, local appliance companies, and HVAC technicians that can help individuals in California to avoid the issue of an AC not working but not blowing cold air. From regular maintenance, to properly sized units and qualified technicians, carrying out these steps can help to prevent this issue, as well as ensure a properly functioning air conditioner that keeps you cool in the summertime. If you are having any issues, make sure to contact a local qualified and experienced HVAC technician right away to avoid any further damage or issues.
