If you are searching for the answer to the question “Why Is My Air Conditioner Not Cooling The House?“, this post should help!
Is the central air conditioner unit in your home no longer keeping your house cooled down? Maybe your unit is only blowing out like warm air, or is it full on hot air?
There is a variety of things that may have resulted in the AC not cooling down like it should. However, for your convenience, we will lest the issues in categories below that you are able to tackle on your own, and then some that should only be attempted by an air conditioning repair professional.
AC Issues You Can Solve DIY
Issue 1. The thermostat is set in the ‘On’ position, rather than ‘Auto’.
If your A/C unit is blowing out cool air on occasion, with warmer air at another time? If this is the case, then your thermoset could be in the ‘ON’ position, meaning it will run the fan constantly without shutting off. However, when set to ‘Auto’ it turns the fans on only when it is cooling.
DIY Fix: Switch the thermostat to the Auto position.
Issue 2. Air Filter is Dirty
When the filter gets dirty the airflow to your AC unit is reduced, which results in various issues.
Evaporator coil: This is the section which cools down the air which is blown out the vent. It is literally freezing the air, and when the air flow is reduced it can turn into a solid ice. This blocks even more air flow, and it will not cool the air coming out as it should.
Struggling AC: When the air flow is reduced, it makes it challenging for the AC to properly circulate the cool air enough to actually cool the room temperature. If this is the case, it can result in situations where the temperature is set at 72, but never drops below 78.
DIY Fix: Make sure the air filter is clean, if it is dirty put a new one in of the same size.
Issue 3. Outside Unit is Dirty
The inside unit of the AC is the evaporator. This absorbs heat in the air, transferring heat which is sent to the outside unit called a condenser.
If the outside unit (condenser) is dirty, it will not be able to dissipate the heat properly and results in the AC struggling to keep the house cool.
DIY Fix: If the outside unit is dirty, spray it down with a garden hose gently. Avoid blasting the unit with a high-pressure stream or you will end up bending fins inside the unit which allows the air flow to properly cool off the condenser.
Additionally, any weeds or debris should be removed that may be growing around the AC unit. These things need breathing room to you know!
Issue 4. Frozen AC Unit
Mechanical issues can cause your AC to freeze up and stop blowing cold air. If you have a a clogged filter dryer, kink in the refrigerant lines, a blower fan that is out of balance or dinged, or a blower fan that isn’t running, then these can cause a pressure change in your AC system and cause the AC to freeze up.
Issues for AC professionals
Below are some issues that could be causing your AC unit not not to work properly, but need a professional air conditioning technician to fix the issue.
Issue 1: Broken or Faulty Condenser Fan Motor
If you find the fan motor is not working properly, or not at all it cannot dissipate the heat properly and the house will not cool down.
Issue 2: Low Refrigerant Leak or Refrigerant Charging
The liquid which absorbs heat out of the air is called refrigerant. If you’re A/C unit does not have the proper amount of refrigerant, it will not properly absorb the heat needed for cooling down the air. When your unit has a low refrigerant level, there is only one cause, you have a leak.
Signs of a refrigerant leak:
- Refrigerant line has ice buildup.
- Hissing or bubbling noises.
- A/C unit cannot properly cool the home, particularly on hot days, but is able to cool at night or on cool days.
If any of these signs fit your situation, you should turn the A/C unit off and contact an air conditioning professional soon as possible. By continuing to run the air conditioner like this, it can result in the compressor to become sluggish which will eventually damage it more, possibly beyond being repaired.
Issue 3. Bad Compressor
When it comes to the core of the A/C system, you have the compressor which circulates the refrigerant through the system like a heart pumps blood through the human body. If this is damaged, your AC unit will not be able cool the air.
If the compressor is having problems, then it could be time to replace it. Unfortunately, an air conditioning compressor will be an expensive replacement. By expensive, we mean if your unit is no longer covered under warranty, it is best to simply replace the entire outside unit.
