Odd smells or sounds—paired with an AC that’s running but not cooling—could mean you have a refrigerant leak (aka a Freon leak). If nothing happens—even after you install a set of fresh batteries (if your thermostat uses batteries)—it’s time to check your circuit breaker. Like any profession, there are many incredibly knowledgeable certified technicians who will work to ensure your air conditioning needs are met, and will do so at a fair price.

Clean Your Air Filters
These issues will need to be addressed by a professional HVAC technician. One way for homeowners to troubleshoot whether damaged ductwork is to blame is to hold a lit stick of incense and run it along the outside of the ducts. If the smoke is blown away from the duct at any point, there is likely a leak in that spot.
Bad or Failing AC Compressor
If the air is cool in some rooms but not others, check to see if the ductwork is damaged or clogged. Maintaining the filters is the easiest thing you can do to improve the operation and lifespan of your air conditioning system. If you have a Nexia thermostat, you can connect your local service company to the thermostat so they have access to some internal diagnostics. Contact Pro-Tech to find out if your thermostat is connected and if we have access to any diagnostic information.
1 Signs Your AC Is Not Cooling Properly
But like any mechanical system, your AC unit relies on many interactions between intricate parts to produce cool air. If one of these parts isn’t working, the entire system may fail. A licensed HVAC professional can take a look and let you know if you have a broken thermostat, which is a relatively simple and cost-effective fix.
For more information on what to expect in HVAC maintenance, check out this article by Homesense Heating and Cooling. It’s best to contact a professional to seal duct leaks as it’s easy to make things worse and cause even more damage if you don’t know what you’re doing. The process of cooling the air in your AC system occurs along the surface and fins of your evaporator coil. And lastly, if your AC isn’t cooling your house—but continues to run and blow cooled air out of some vents—it could be your ductwork.

With proper guidance, you can perform routine air conditioner maintenance yourself. Always turn your AC unit off before doing any work, as failing to do so is likely to cause serious injuries. If your air conditioner is having issues, it’s best to call in a professional.
Frozen Evaporator Coils
Air conditioners are “sized” according to the amount of cooling they can provide as measured in BTUh (British Thermal Units per hour). Under moderate conditions, you may not notice any issues with an undersized air conditioner. However, as temperatures rise outside, your AC may run for long periods of time and struggle to keep you cool.
Unfortunately, there are also unscrupulous HVAC technicians who may take advantage of their expertise to charge you more than your share. Try to clean your air conditioner filter at least once every three months. The greater the frequency of cleaning it, the better your house’s air quality will be.
Should you turn off the AC if it’s not cooling?
Over time and without proper cleaning, air filters can become clogged and prevent air from properly passing through. Additionally, when clogged air filters trap cool air inside the unit, the evaporator coil is at risk of freezing, which could restrict airflow. The indoor air handler also has evaporator coils that remove heat from the air. The indoor coils can become dirty and clogged if you do not change your air filter on a regular basis. We do not recommend that you attempt to clean the indoor coils as they are more delicate than outdoor coils.
If your filter is dirty, swap it for a new one to help your air conditioner cool more effectively. These were the basics of what to look for when trying to solve the problem of air conditioners not blowing cold air but running. If your refrigerant is slowly leaking from the refrigerant lines, you will start seeing your air conditioner cooling less and less. This is a less frequent cause of central AC not blowing cold air; it might help some homeowners, however. We have already talked about the air conditioner being “flooded” when there is no adequate drainage. To get rid of the ice, just run the air conditioner with the fan on, and the cooling system off.
If there is a leak in the unit, there isn’t enough refrigerant in the coils. The AC running but not cooling is a sign that the refrigerant might not be adequate. If the evaporator coil becomes dirty or air flow is inadequate, the coil can freeze over. In this situation, you may notice a gradual change in the AC not cooling the house.
That will melt the accumulated ice and release the cooling coils. Only after the cooling coils are out of the ice shell you can start using the air conditioner properly. In more cases, the best way of action is just to replace the clogged filters. MERV 5-12 filters used in AC units are fairly inexpensive; you can get a pack of 6 filters for about $60 (depends on your air conditioner, MERV rating, and so on).
If the switch was accidentally set to “Fan,” the unit will blow air through the duct system, but no cooling will take place. There are several possible causes of an AC system that is blowing warm air. The following are a few things to check when your air conditioner is not cooling your space. Some AC issues are easy enough to diagnose on your own, but you’ll ultimately need to call in an expert to help fixthe problem. For example, if you hear a bubbling or trickling sound coming from your air conditioner, it couldmean that your AC unit is low on refrigerant.
