HVAC Ultimate Guide – Why is your Home AC not Blowing Cold Air?

Barbecues, swimming pools, vacation, and fun— that’s what summer is all about. But with this also comes that terrible heat. The only thing worse than summer temperatures is when you air conditioning doesn’t work for some reason. Don’t worry, if you are wondering why is your home ac not blowing cold air then we can help you figure out the problem in no time at all!


1. The Thermostat is Set Incorrectly

If you find your home ac not blowing cold air, the fix may be as simple as checking your thermostat setting. Although this seems obvious, this happens more often than you might think. It’s easy to trigger the wrong programming accidentally. Be sure to set your fan to “auto.” This will not only save you money but ensure you fun only runs when the air conditioner is cooling your home. Otherwise, if you fan is set to “on” it will always be blowing air regardless of what the temperature feels like.


2. The Unit is Leaking Refrigerant

When the central air conditioner is not cooling, there is a good chance that you have a refrigerant leak. As a result, you can have issues with your home ac not blowing cold air or may working as effectively as needed. This is usually an easy fix, but you need to be sure you have a technician do it because handling refrigerant can be difficult.


3. AC Not Blowing Cold Air? Maybe it’s Dirty Air Filters

A Lot of the reasons you may be wondering “why my ac isn’t cold” comes back to routine maintenance. Learning what to do and how often to maintain your HVAC system depends on how much you use it, but generally, it’s a good idea to have a technician come by at least twice a year.

In addition, there are simple steps you can take such as replacing the air filters. A good rule of thumb is to change the filter at least once a month to prevent debris from building up. Every few weeks is even better! In this fashion, your home ac not blowing cold air may just be a result of a need for regular maintenance.


4. It Could Be Your Circuit Breaker

When your home ac is not blowing cold air, it’s easy to assume the worst. But the solution may be a simple as flipping a switch. Your a/c unit utilizes outdoor and indoor components. If the outside one trips and the inside doesn’t, your unit will still blow air, but not cool it.

Simply reset the breaker. However, if it trips quickly again then contact a service professional. This can be a sign of a bigger problem.


5. Leaking Air Duct

Your a/c works by pushing air through the vents. If there is damage to the insulation or the ducts, the cool air can get lost in the process and the efficiency of your system can be seriously affected. If you have an older home, then you’ll want your ducts professionally checked out.


Still No Cold Air? The Solution is Simple.

If you find your home ac not blowing cold air or not working efficiently, it can be attributed to one of many different reasons. Don’t worry though with a simple air conditioning service, you can get your unit fixed and ready for whatever summer weather comes your way!
