You should take action as soon as you identify a problem. Don’t wait until the heat is oppressive to begin cooling down. An HVAC service call should be made whenever you’re unsure of the problem.
Your HVAC system ceasing to circulate cold air might be caused by a number of factors. Some are straightforward and may be handled right once, while others necessitate the assistance of a professional.
If your air conditioner isn’t blowing cold air, take a look at these possible causes and solutions.
How Does a Central AC System Work?
Knowing how your air conditioner works will help you figure out what’s wrong if it’s not working properly.
Liquid refrigerant is used in your air conditioning system. The heat is absorbed by this liquid as it flows over the indoor evaporator coils. This liquid is transformed into an ice gas by absorbing the heat. The fan of the air conditioner pushes cold air through the ductwork and into the house by blowing across the refrigerant-cooled coils.
Once it reaches the outdoor condensing unit, a gaseous refrigerant transfers the heat back there, where it cools and becomes a liquid. Your house will stay cool thanks to this cycle. With so many steps, there are numerous things that could go wrong.
Let’s look at the best five.
1. Leaking or Low Refrigerant
Puron or R410A are the two most often used refrigerants, and it is these two substances that set the whole process in motion.
If your central AC is not blowing cold air, the refrigerant may be the problem. It’s possible that the refrigerant is running low and that the unit needs to be recharged.
In the vast majority of cases, this is the result of some sort of leak. In addition to preventing the air conditioner from cooling adequately, a leak can also lead to other problems in the house. Humidity levels might develop in your home if the temperature isn’t kept cool enough, making it appear hotter inside than it actually is.
An HVAC technician should be contacted immediately if you suspect a leak of refrigerant. When a small leak is detected and repaired, it can be difficult to accurately identify and remedy the problem correctly.
2. The Filter Is Dirty or Clogged
Dirty or blocked air filters are another typical problem with air conditioners. Throughout the year, these filters are constantly collecting hair, lint, dust, and pollen in their pore-sized holes. If they are not changed on a regular basis, they will quickly fill up.
In the event that this occurs, your air conditioning unit may shut down due to a lack of supply of air. The indoor temperature rises if the air conditioner is not working properly. Clogged filters can also cause parts to wear out more quickly if left unchecked for an extended period of time. Even the condenser and evaporator coils can be affected by this.
The filters should be replaced every three months in addition to the regular cleaning. You may need to do this more frequently if you have indoor pets.
You should be able to replace your indoor air filters on your own without any help. AC technicians can aid if you’re unclear of the suitable filter to use.
3. There Is a Problem With the Evaporator Coil or Condenser
In spite of their best efforts, the coils themselves will eventually need to be replaced due to wear and tear.
Indoor evaporator coils are particularly vulnerable to the growth of mold and mildew because of the constant presence of water in the air. In order to prevent this, you can use UV lights to keep your air cleaner. Because of low refrigerant levels, coils might also freeze up.
Problems with the air conditioning unit’s coils should be addressed as soon as possible by an HVAC technician.
Over time, the condenser can potentially fail. If you can’t find any other explanation for why your air conditioner isn’t blowing cold air, have this checked out.
4. Blocked or Clogged Registers
A clogged or blocked register (or vent) can have the same effect as a clogged or blocked air filter. Supply vents blow conditioned air into the house through a return air register. In any case, clogs can cause issues.
Cooling will be affected if there is an obstruction or leak in the ductwork of the ventilation system, which runs throughout the house. Your attic may be leaking cold air if your ductwork has a rip or a hole in it. Mice and rats that live in your attic can wreak havoc on your ductwork, causing leaks and causing your system to overheat.
Ventilation may be restricted in a particular room because of a blockage near the vent, making it feel hotter than the rest of the home. That’s a good sign that the ducts supplying conditioned air to your house or office have a ventilation issue.
It’s also worth mentioning that vents can be accidentally shut off. Make sure the supply vent is fully open if the temperature in one room is very high.
Repairing your HVAC system will get increasingly expensive over time. Consider a new system if you see these issues.
5. AC Not Blowing Cold Air – Thermostat Issue
Everything begins with the thermostat. It is not until the room temperature exceeds the control level that the air conditioner will turn itself on. First, check the thermostat setting. Auto or cool mode should be selected. If the thermostat is set to heat rather than cool, the problem occurs.
If the thermostat is adjusted correctly, but the AC is still not working, the problem may be with the thermostat itself. Check and replace the batteries if necessary if it uses batteries. An air conditioning technician should be contacted if that doesn’t fix the issue.
Proper Maintenance Prevents AC Not Blowing Cold Air
Your central air conditioning unit, like any other machine, requires routine maintenance. Changing the filters and inspecting the rest of the operating components is necessary.
An HVAC maintenance tune-up is typically recommended twice a year. In the spring and fall, this should occur. Before the weather gets too hot or too cold, the expert can inspect your HVAC system and make any necessary adjustments or repairs.
Your unit will run more efficiently, and it will also lessen the danger of costly breakdowns or breakdowns in the future.

AC Problems a Professional Should Solve
Broken Condenser Fan
Having a broken or defective condenser fan will prevent the outdoor unit from being able to chill your home effectively.
Low Refrigerant Level
The liquid that absorbs and then cools the heat from your house is known as the refrigerant. You may have a leak if you see ice on the refrigerant line or exterior unit, or if you hear bubbling or hissing. Immediately turn off your air conditioner and call a professional if you observe any of these warning indicators. If you leave it on, you run the risk of damaging your compressor.
Your air conditioner’s compressor is its beating heart. The refrigerant is exchanged between the indoor and outdoor units using this device. When a compressor fails, the outside unit must be replaced, which can be expensive. For your own safety, you should always have a qualified expert inspect the system.
Damaged Air Ducts
To bring fresh, conditioned air back into the house, the ductwork in the attic is utilized. Attic air can escape through the duct and into your home, making it appear as if your air conditioner isn’t working properly. Age, vermin and structural flaws all contribute to the degradation of air ducts. The ductwork in your home should be checked out by an HVAC specialist for any potential problems.

It’s A Wrap
The article “Why is my air conditioner not blowing cold air?” has come to an end.
Every month or every six months, you should have your air conditioner checked and analyzed. Some of you might think that maintenance is unnecessary, yet it’s always required, regardless of what you think.
The debris that got lodged in your AC components because you didn’t inspect could cause severe harm to your AC if you don’t do this. Keep your filter clean at all times.
We’re crossing our fingers that you’ll be able to resolve your issue soon!
