Among the possibilities are: After the temperature setting is reached, the air conditioner continues to run.
- a constant rumbling
- a rise in the cost of electricity
- Vents and fan blades are iced up
- Vents are dripping with water.
- If any of these problems are found, it could mean that the device has internal damage or a component failure that need repair.
Here are a few possible solutions to the problem that we might examine.
How Long Should Air Conditioning Run to Cool a House?
As a first step, we need to figure out how long an air conditioner should run to cool the entire house to the desired temperature.
Typically, a normal air conditioner cycles on and off every 15 to 20 minutes while it cools the entire house, eventually shutting off once the specified temperature has been reached..
When the temperature begins to increase above the prescribed temperature, it will restart after a predetermined amount of time.
When working regularly, the on-off cycle period and the time it takes to restart after a power outage are determined by a variety of factors. Here are a few things to consider:
Air Conditioner Size and Power Output
Size and power output of an air conditioner should be proportional to the volume of the building it is cooling.
Air conditioners can cool an entire house in just 10 minutes if they’re too strong or massive for their surroundings, but this isn’t always the case. That, on the other hand, may not be the best course of action.
A cooler that is either too large or too powerful will use more energy, which is both wasteful and expensive. Excessive drying of the air, especially in people with pre-existing respiratory diseases, is another risk.
If a cooler is too tiny or weak, it will have to work more and use more energy to reach the desired temperature.
Undersized air conditioners may not be as effective at reducing humidity levels, which could lead to a more humid atmosphere in the home. Component failure and subsequent high repair expenses are possible side effects of an overworked air conditioner.
The cooling ability of an air conditioner is influenced by the ambient temperature.
When it’s excessively hot or humid where you live, an air conditioner’s cooling cycle can take upwards of 15 to 20 minutes longer to chill the entire house. The cycle can also be accelerated if the ambient temperature is reasonable.
This information can be used to estimate how long it will take your air conditioner to chill your home.
How Long Should an Air Conditioner Run Each Day?
Knowing how long an air conditioner can operate each day is also helpful. Several factors, such as the following, must be taken into account:
Air Conditioner State and Efficiency
The general condition and efficiency of the equipment have a significant impact on its ability to chill your home.
As a result, a properly maintained air conditioner that is in good working order will be more effective at cooling your area while also being more cost-effective to achieve and maintain a suitable indoor temperature, as well.
Running times and cooling efficiency are affected by factors outside of the equipment itself. Among them are:
As a matter of fact, the temperature outside will have an impact on how long an air conditioner must operate to chill the entire house.
The AC will have to operate all day long on those hot summer days. Even on a somewhat warmer setting, the AC will need to run all night if the nights are hot and especially when they are humid, even if it saves energy and prevents the house from becoming too cold to be uncomfortable for sleeping.
According to one theory, turning the air conditioning on and off often during the day will save electricity.
This approach, however, has been demonstrated to contribute to increased energy consumption as well as short cycling, which can impact the effectiveness of air conditioning equipment and also lead to larger instances of wear and tear, limiting the equipment’s life span.
For milder days, running the air conditioner for 10 to 15 minute cycles may be sufficient to keep the house cool. However, the thermostat is the best way to get the most out of an air conditioning system.
You should not try to control the temperature manually by manually turning the AC on and off. The thermostat does this for you automatically. That brings us to the following consideration:
As a result of the thermostat’s settings, air conditioning running time and energy consumption might be greatly affected.
To avoid overheating in really hot weather, you’ll need to run the air conditioner for longer if the thermostat is set low enough.
It is possible to shorten the AC run cycle duration by lowering the thermostat’s temperature setting to a level that is neither too hot nor too cold, but rather more comfortable as it should be. It will also save money on electricity costs as a result of this.
Air Conditioner Size and Power Rating
Size and power rating are two of the most important factors in determining how long an air conditioner will run.
Even while it will chill the space faster, a too large and powerful unit will use significantly more energy than is necessary to attain the desired indoor temperature and climate comfort level.
A smaller or underpowered air conditioner may need to run longer cycles (about 20 minutes) in order to cool a larger space. As a result, the cooling system’s lifespan will be shortened due to increased demand.
If the cooling equipment does not fit the specified space, it is imperative that it be properly sized. Reduced load and wear make it possible for a properly sized AC to operate at higher efficiency and lower cost.
Size of the Space
When it comes to air conditioners, the size of your home’s habitable space is an important consideration.
It may take longer for the AC to maintain a cool indoor temperature in a large room, depending on the size and power output of the equipment.
In order to save electricity, it’s a good idea to only cool the room (or rooms) you’re actually using if you have a tiny, portable air conditioner. Keep the doors and windows closed in unoccupied rooms to prevent heat from those rooms from escaping into inhabited areas that are being cooled by the air conditioning system.
In order to keep a room at a suitable temperature, it is required to run a portable air conditioner for an extended period of time.
How Long to Cool a House From 80°F to 72°F?
Take into account some of the suggestions made above if you need to chill your home from 80 degrees to 72 degrees.
On a reasonably warm day, a medium sized house may be cooled from 80° to 72° Fahrenheit with a well-sized and balanced air conditioner in around 4 to 6 hours. if it is working as effectively as possible and the vents are not obstructed
10 Reasons an Air Conditioner Keeps Running After Reaching Temperature Setting
After reaching the desired temperature, the air conditioner should not continue to run without a reason. Knowing what it is may help to avoid undue wear on AC components and wasteful energy use.
The following are ten typical explanations for why an air conditioner continues to run even after the thermostat has been set to the desired temperature:
Evaporator Coil Is Dirty
A filthy evaporator coil is one of the most common causes of an air conditioner to keep operating even after it has reached its desired temperature..
In order to cool the refrigerant gas, the evaporator coil must be installed. The evaporator coil can become clogged with grit, dust, and other debris when the air is humid. This can cause it to operate at a slower rate than normal, resulting in slower air conditioning.
The evaporator coil must be cleaned to fix the problem. If you’re handy with tools, you can do it yourself or hire a professional HVAC expert to do it for you.
The evaporator coil can be cleaned in a number of ways, including:
To clean a dirty coil, it may be best to engage a professional to do it.
Evaporator Coil Is Frozen
Warm air from the air conditioner is a strong indication that the evaporator coil has frozen.
If you want to know why the evaporator coil has frozen, you’ll have to do some digging. These steps can help you defrost the evaporator coil if you’re not a trained professional:
- Defrost the frozen evaporator coil by turning off the air conditioning for 24 hours.
- Clean the evaporator coil while it is thawing if it appears dirty.
- Verify that the air filters are free of dust and debris. If they become stained, get new ones.
- Make that the evaporator coil is not damaged in any way. Call a technician if it appears to be damaged.
It’s advisable to call a specialist who can also check the refrigerant levels and check for leaks, fixing or replacing any component that needs it.
Air Filter Clogged
Filters that get clogged up might lead to a variety of issues. A clogged air filter reduces the amount of air that can flow through the system.
As a result, the home’s air conditioning unit may have to operate longer and harder to achieve the desired temperature.
Replacement air filters should be purchased, the old ones removed, and the new ones installed (follow the directions to ensure the filters are facing the correct direction).
A simple soap solution and a vacuum are all you need to remove the air filters from most air conditioning systems and clean them before putting them back in.
Changing or cleaning the AC air filters on a regular basis is a good idea.
Excessively Restrictive Air Filter
High MERV air filters are known for limiting airflow. As a result, an air conditioner may run for longer periods of time because it takes longer to cool the area.
The MERV rating of the air filter should be replaced if this is an issue, typically between 8 and 11 for residential or light business use.
Leaks in Ductwork
In older buildings, where the ductwork is ancient, this is a prevalent problem.
Leaks in the ductwork can cause cool air to escape, increasing the load on the air conditioner and requiring it to operate more frequently.
The detection and repair of leaks or the replacement of really old ductwork can take a significant amount of time and effort, making leaky ducts a difficult problem to fix.
In many circumstances, hiring a professional to diagnose and remedy the problem is more cost-effective than doing the task yourself, even if you have some knowledge in the field.
When the thermostat malfunctions, the air conditioner may continue to run even when the temperature has been set to the desired level.
It’s possible that the thermostat is malfunctioning and failing to shut off the system because it doesn’t recognize that the temperature has been adjusted correctly.
Check to see whether the thermostat has a problem. Often, a technician will be needed for this. Replacement of the thermostat is normally recommended in the event of an issue.
To keep the temperature down, the AC may continue to run even if the refrigerant level is low.
When the evaporator coil has a leak, this is a common occurrence. As a result, the air conditioning unit may have to work harder to keep the room at a comfortable temperature.
In this case, you’ll need a skilled HVAC technician to find and fix any leaks.
Using a freon leak repair kit may be viable for tiny leaks, but it’s recommended to consult a professional.
Condenser is Dirty
Filthy condensers, like dirty evaporator coils, can cause air conditioning to continue to run even when the temperature has been reached.
Airflow can be impeded by the collection of dust, dirt, leaves, and other debris. This can lead to malfunctions in the cooling system.
Using a high-quality condenser coil cleaning, you may do routine maintenance on the condenser unit or coil on your own. Here are a few tips to help you get started:
Check the condenser coil and its housing for any debris, such as leaves or other small pieces of vegetation.
Clean the condenser unit’s debris with a coil brush.
After brushing, straighten the coil fins.
Clean the condenser coils using a foaming condenser coil cleanser.
Leave the foamy cleaner on for 10 minutes, then rinse it off with water.
Incorrectly Sized Air Conditioning Equipment
If you’ve modified your cooling system or equipment, or if you’ve rearranged the layout of your home, this applies.
It’s possible that the AC isn’t the right size or power output for the structure.
A load calculation is usually the best way to deal with this issue. As a result, this might help you choose the ideal answer for your situation.
Blower Motor or Fan Issues
If there is a problem with the fan or blower motor, the air conditioner may continue to run after it reaches the specified temperature.
It’s possible that the blower motor or fan isn’t producing enough air or is running too slowly.
Adjust the fan speed if necessary. If your fan blades are caked with dirt or debris, try cleaning them. You might be surprised at the results. The fan or blower motor may need to be replaced if they are old and failing.

What to Do When Your Outside AC Unit Runs Constantly
Avoiding the problem might lead to more expensive and time-consuming repairs. If you follow these basic troubleshooting methods, you can avoid more serious issues and keep your home cool as the hot weather returns.
Reason #1: AC Runs Constantly Due to Restricted Airflow
The inability of a house to cool itself is one of the most prevalent causes of an exterior AC unit running nonstop. To keep a house cool, how long should the air conditioner be left on? Within 10 minutes, your air conditioner should begin to lower the temperature.
Your house will be hotter if you have a dirty air filter, closed supply vents, or blocked return grilles. Here’s how to figure out if your home is getting enough fresh air:
Change your air filter at least four times a year as part of appropriate AC maintenance. Your airflow will be improved if your filter is unclean or has not been replaced for some time.
Open supply vents: to aid in the cooling of your home, ensure sure all vents are open, including those in areas not in use.
Ventilation can be impeded by draperies or furniture, so check to see if any of the grilles are obstructed.
If, despite taking these steps, you’re still having trouble breathing, it’s probable there’s a more serious problem. Poor airflow can be caused by a variety of things, including a leaking duct system, a broken blower motor, or frozen evaporator coils. In these situations, it’s best to enlist the help of a qualified professional service.
Reason #2: AC Runs Constantly Due to Low Refrigerant
“Why does my air conditioner run constantly?” is a reasonable question to ask. Another possibility is that the refrigerant is at a low level. In an air conditioner, the condenser and evaporator coils are filled with a chemical substance known as refrigerant that cools the air. The AC will not be able to chill you down if the refrigerant level is too low.
A leak is almost often the cause of low refrigerant levels. In the event of a refrigerant leak, it is possible to see frozen evaporator coils. The source of a refrigerant leak can be properly determined and repaired by a professional AC service.
Reason #3: AC Runs Constantly Due to Dirty Condenser Coils
“Why does my air conditioner continue to operate even after it has achieved the programmed temperature?” It’s possible that unclean condenser coils are at blame. Coils may become clogged with dirt, preventing refrigerant from absorbing heat from the warm air in your home. Dirt on the outside of the coils prevents heated air from exiting, and the coils remain too hot to cool the refrigerant, causing it to overheat.
When your exterior air conditioning unit is consistently running, call in a professional to clean the condenser coils and check for any other problems. Give us a call if you have any questions or concerns now that the warm weather is here to stay!
