A small window AC is expected to cool only a small space like a single room. Even so, it may not provide even cooling in the entire room. However, with central air conditioning, we do expect that it will cool the entire house evenly and effectively. If your air conditioner is not keeping you cool, this can be frustrating and cause for alarm.
When you install a central air conditioning unit in your home, you want it to hold up against the heat and deliver enough cooling to keep your entire home cool. Yes, there will certainly be some temperature variations depending on the home, but overall it should feel similar to the thermostat setting.
If you are having problems with your air conditioner not keeping cool, your professional HVAC contractors can help. Whether you are looking to install or service a central air conditioning system, it is important to choose the best St. Louis HVAC contractors to do it for you.

5 Common Reasons Why Your AC Is Not Keeping You Cool
Here are the top 5 most common reasons why your air conditioner is not cooling as you expect.
- Improper installation: If it is a brand-new air conditioner, the problem might be that the installers cut corners and installed an air conditioning system that is inadequate for your home. A new air conditioner must be precisely sized to ensure that its cooling capacity fits the home’s requirements. The only "solution" to this issue is to have a professional replace the air conditioner with one that is the proper size.
- Clogged air filter: If your air conditioner is not cool, the issue may be as simple as a clogged air filter in the HVAC system. If the filter gets clogged, airflow entering the air conditioning system will be reduced, and the volume of air cooled will be reduced. To solve this, all you have to do is install a new filter—and be sure to replace it every one to three months.
- Blocked outdoor unit: The condenser is the exterior unit of a split air conditioning system, and it is where the heat from within is expelled to the outside. The cooling capability of the AC will be reduced if this unit is blocked or clogged by plants, branches, or excessive dirt.
- Leaking refrigerant: Air conditioners with refrigerant leaks are a typical problem, especially in systems older than five years. The cooling capability of the system reduces when the refrigerant level drops. Other indicators of a refrigerant leak include a rise in humidity, ice on the evaporator coil, or a bubbling sound from the air conditioner. This is an issue that only specialists can solve: the leaks must be sealed, and then the lost refrigerant must be replaced.
- Malfunctioning thermostat: Finally, if your air conditioner is not keeping cool, the problem may actually be the thermostat instead. Your air conditioner may be running properly, but the thermostat that regulates it might be malfunctioning. If the thermostat detects any inappropriate temperature in the house, the air conditioner will be turned off before it reaches the intended temperature. Recalibration or replacement of the thermostat is a simple task for technicians.
