Reasons Your AC Isn’t Blowing Cold Air

One common question that you’ll hear during the summer season is “why is my AC unit not blowing cool air?”. Perhaps you’re one of these people who are always asking this question. It does not matter. Your AC should work properly this summer to ensure comfort during the warm months. If it isn’t, you will have to troubleshoot it right away.  

Lucky for you, we’re here to help. Before you contact a residential HVAC technician for help, here are a couple of things you can do if your AC isn’t cooling your home: 

Is Your AC Not Blowing Any Air? 

There are a couple of steps you can follow if your AC isn’t blowing any air and it isn’t working at all. 

• Inspect that Electricity is Going to Your AC Unit 

This means that you’ve got to inspect service switches that are located  

• At the circuit breakers or fuses in the electrical panel 

• At the air handler inside the air conditioner 
• By the compressor in the outdoor unit 

There might be an issue with your AC unit if any switches are set to “off”. For instance, your AC will automatically shut down if the condensate drain line is clogged and water leaks. This is particularly true if your AC has a water sensor switch. This will help avoid water damage to your house.  

In addition to that, your AC might also be overheating. This causes the unit to use more electricity than the circuit breaker can manage. Thus, the circuit breaker will cut power to the unit. You shouldn’t ignore the problem if your circuit breaker keeps cutting the power after you use your AC for a period. You need to hire a professional right away.  

• Examine the Air Filter 

A dirty air filter will obstruct the airflow and freeze the interior of the unit. If you’ve got dirty air filters, change them right away.  

• Ensure the Thermostat is Set to Cool 

It might appear obvious. However, you’ll never know if one of your kids or your dog accidentally changes the settings of your thermostat.  

Is Hot Air Coming Out of the Supply Vents? 

• Examine the Outdoor Unit of Your AC 

Clean the unit if it is covered in grass, dust, or dirt. Give the outdoor unit a breathing room if it is smothered by a bush or a tree branch. You might have to hire a professional if the outside fan isn’t working. Else, the outdoor unit cannot cool down the refrigerant to cool your home.  

• Examine the Air Filter 

Examine the air filter to see if it’s dirty if the air coming out of your supply vents isn’t very cool. If they are dirty, change them right away. This will help prevent blockage of the airflow to the air handler.  

• Examine the Fan Settings of Your Thermostat  

Does your AC run hot air sometimes and cold air most of the time? You shouldn’t set the fan setting to “on”. Professionals recommend that you set it on “auto”.
