Why Is My Air Conditioner Not Cooling the House?
Summers is in full force, and it’s blazing hot outside. With this kind of weather, air conditioners are a real Southeast Texas necessity.
You come home ready to cool off in comfort. But wait! Why is it so warm inside?
The air conditioner is running but not cooling the house!
There can be various reasons for your AC running but not cooling. Let’s have a look at the most common problems with your air conditioner that prevent it from working efficiently.
Very High Temperatures
Every AC is designed to tackle a specific highest temperature. Usually, that is up to 94 degrees. But what if the temperature rises above 94 degrees?
In Southeast Texas, where the temperature gets very high, the AC might reach its limit. The fault then is not with the Air Conditioner but with the weather.
We can’t do anything to change the weather. Try turning your thermostat up a few degrees to help your unit keep up.
Size of the Air Conditioner
Another non-technical fault causing non-cooling of your AC is its size.
You might think that the AC is not cooling enough, but you might actually have an undersized AC.
If the AC you have installed is too small for the size of the area it is cooling, it can be unable to bring down the indoor temperature.
Keep in mind the size of your home when selecting the air conditioner.
How often do you take a good look at your outdoor AC unit? Many of us ignore it, which causes us trouble down the line.
Your unit requires continuous airflow, but it can get clogged with dust, weeds, or even bird nests.
Regular air conditioning maintenance is very important. Keep it clean of any dust and debris.
You can also spray around the base of your unit with a weed killer to prevent the growth of weed and grass.
Refrigerant is a liquid inside the compressor that cools the hot air when it passes through the liquid. It might leak, and low levels of it can result in your AC not cooling the home.
But how do you know that refrigerant is leaking? You need to look for these signs:
- Any frozen ice on refrigerant lines or outdoor unit
- A whistling or hissing sound
- AC cools at night but not in the day
If you find any of these signs, you should stop using your AC right away.
Contact a professional air conditioner repair company immediately to come and fix the issue.
Refrigerant is not like car fuel, which runs out. It is recirculated in the unit. If its level is low, it’s because of some leak. Ask the repair company to look for and fix the leaks.
Dirty Air Filters
All air coming out of your air conditioner is filtered first. Air filters trap all the dust and debris from the air. If they are not changed, the filter can become clogged and hinder airflow.
Replace your air filters regularly.
Did you recently get a new air conditioner? Is it not cooling enough or at all? It might not have been installed properly.
Get the AC checked by a different air conditioner repair company. The previous company may have made some mistake.
If your AC is not cooling and you see no problems mentioned above, then there might be a problem with your electrical connection. A breaker might be “off” or even flipped a bit but not completely OFF.
Check all of your breakers. Turn all AC breakers OFF and then ON. This might help your AC to work properly.
Not Getting Enough Airflow
It is important that the compressor gets continuous airflow. The airflow might get blocked due to any dirt or frozen ice at the coils.
Here’s how to check if the airflow is insufficient:
First, check for an obstructed airflow using the Carson Dunlop method. Hold a tissue up to a cool air return duct. There should be enough suction to pull the tissue inward.
If this is not the case, there could be some obstruction in the duct or the coils.
Clean air filters of any dust. Check for ice around the coils. You can also contact a professional AC maintenance service.
Frozen Air Handler
None of these helped you? Don’t worry.
There is another place to check: the evaporator coils behind your air filters.
A frozen AC unit will not cool your home. It sounds strange, but it’s true!
If these coils are frozen, it will prevent the contact of hot air with the refrigerant in these coils. As a result, you’ll get hot air from your AC.
If the coils are frozen, just switch off your AC for the next 24 hours. Let it completely defrost and dry before using it again.
Your thermostat might not be working properly due to weak batteries or any other physical damage.
If you see a blank screen, consider replacing batteries. Moreover, set your thermostat on “AUTO” instead of “ON.” This will switch on only the fan and not the cooling system.
Summing It Up:
If your AC is not cooling enough, try to look for any of the above issues and resolve them in a proper manner.
If the temperature is very hot outside, try to keep your windows and doors shut to prevent the entering of hot air.
Also, choose the right size of AC according to the size of your home.
In addition to this, keep up on the cleaning and maintenance of indoor and outdoor units.
Finally, it is very important that if you are unable to understand the problem, contact a professional company. Many AC repair companies offer their services at economical rates. Call Air Services Unlimited today to learn more about our AC maintenance options.
