If you want to cool your home, then you’ll have to invest in 1 of 3 options. You need to get a central air system, individual AC units, or evaporative cooling units installed in your home. While something like individual units and evaporative cooling units are something that you can install yourself, a central air system is a big step that involves a powerful system. Here’s more information about the 3 units and how much time it may take to cool your home.

Central Air

If you have central air, it means you have a system where air is pulled to a central location and distributed throughout the rooms in your home by one or more fans accompanied by ductwork. The air conditioner compressor makes the whole process of air conditioning possible in the system. The refrigerant is compressed and the gas enables it to discharge heat out of the house, which is how cool air is created.

You might have one of two types of central air conditioners. You might have a split system, where an outdoor metal cabinet has the condenser and compressor an indoor unit has the evaporator. You could also have a package unit which is where the evaporator, condenser and compressor are all located in one cabinet that usually stays on the roof or on a concrete slab next to the house. Both of these systems used to connect to the air conditioner to distribute cold air throughout the house.

Central AC allowed you to be comfortable indoors during warm weather. It keeps your home cold and it can decrease humidity levels inside. It also gives you clean air because it draws air out of the room, and the air is pushed in the air filter to remove particles like dust and lint. It also is much quieter than any of the other options because the compressor unit is located outside of your home.

If you have a central AC, it’ll usually take around 3 hours to cool an average sized 4 bedroom house. This is dependent on a few factors that will be discussed later, but overall if it takes significantly longer than 3 hours, you might need to call a professional to take a look at it.

Individual Units

Individual AC units work differently than a central air unit. The central air unit moves air all throughout your home. If you have a portable AC unit or a window AC unit, it will drastically cool down the room that it’s in, but it likely won’t quickly cool down your entire house. It uses the same technology as the full system uses, except that there are no ducts to carry it all throughout your house.

It is usually a soft like unit that takes in hot air, pulls it and then pushes out the heat. It then takes the newly cold air and blows it out. All of this happens in the same small Union. It’s going to happen because of a condenser coil that cools the air and there’s usually an exhaust hose , which releases the heat. The cool air is pushed into your room to give you the relief that you need when it’s hot. Individual AC units push the cold air into the room it’s in and the process will continue repeating until you turn the unit off.

An average sized living room or bedroom will be cooler in about 20 minutes. If you want to pull down your entire house when you have only individuals in it, and then you have to add more if you need two different faces in the hole. There are a lot of different portable AC units that you can use around your house to cool it down. Portable AC unit (View on Amazon) will likely cool that room in 20 minutes also, so there’s no way to have only one unit cool your entire house, especially if it’s more than 1 floor and multiple bedrooms.

Evaporative Cooling

Evaporative cooling is different from having an AC unit. It uses water soaked pads to pull heat from the air. This works because its fan pulls hot air into the unit to push through the soaked pads. These pads use that hot air to evaporate the water into a gas. The gas will be pushed out cooler than it was when it enters the unit.

These won’t work well in a dry environment. It can be an effective method for cooling yourself down when it’s hot because it adds moisture into the air. The evaporative coolers work well in hot, dry areas where the air doesn’t have any moisture to cool you down. However, for the hot temperatures in humid areas, these are basically ineffective because the air is already filled with moisture and adding more moisture to the air isn’t recommended.

Evaporating cooling systems will take longer to cool your home then an AC unit will. Evaporative cooling systems cool the air and space out cycles. There are about 15 cooling cycles per hour, so you might not feel a drastic change in the temperature for a few hours or more depending on how big your home is.

Factors that Affect How Long It Takes to Cool a House

Numbers given above represent an estimate of the Amount of time it should take to cool your house. There are a lot of different factors that will affect the cooling time. Here are some of the factors that you should keep in mind when you’re considering the cooling time.

The Air Filters

How often do you change your air filters matter. Air filters filter out the dust and debris from the air. This is why they can get covered. If you don’t change them regularly, the debris and dust will block the airflow. This means your AC will have to work harder to pull down your home and this will drive up your energy bill. This also increases the amount of time that it takes to cool down your home.

You should change your air filter often. The amount of times that you need to change the air filters is dependent on the number of people that live in your home, whether you have pets, what type of air filters you use and whether you have allergies. You should make it a point to check them once a month so that you can change them if they look dirty. But, if they don’t look dirty, you can leave it until they do and save some air filters.

The Season

The time of the year matters. When it’s higher temperatures during certain times of the year, it can take longer to cool down your home. You can try to speed things along by using blackout curtains, getting some drapes, and closing your blinds, but you’ll still experience longer cooling times.

You should consider ensuring that your air conditioner is up-to-date and working correctly during the hotter periods of the year where you’re going to end up using it more often. Otherwise you cannot help it is hotter outside and takes longer to cool your home. If you need to, you can couple the AC with a fan to make it more comfortable inside when the heat is still overwhelming. Otherwise, during summer if it takes too long to cool your home, you might want to consider calling a technician to fix the issue so you can be more comfortable.

The Age of Unit

The age of the unit impacts how quickly it can cool your home. If you installed your AC system a long time ago and haven’t updated it, then you might need a new model. Newer units cool your home faster and they also have new environmental regulations to follow. They have different refrigerant and air conditioning designs that are better for the environment and more efficient in your home. Because of this, if you have an older unit, you might want to understand that you will have to wait more than be a lot of time for your room or home to get cool.

The Size of Your House

if you have a smaller home, and the AC has less places to spread. This means it’ll cool down a lot faster. For an average 3 to 4 bedroom house if should take 3 hours for the central AC to cool down your home. If it’s much smaller than that and you have sent you a seat, then it will take a lot less time. If it’s larger than that then you should allow more time for your house to cool. You also might want to keep in mind that your AC might have other issues to deal with, like dirty coils, a faulty condenser unit or a refrigerant leak. All of these things can mean that your house takes longer to cool, especially if you have a large home with a faulty AC unit. Make sure your AC system is up-to-date and that you have green air filters so that the air can flow into your home.

The Insulation in Your House

Respirations can also cause problems in your home. Insulation slows down the transfer of heat when it’s hot outside and the same thing happens when you have cold weather up side during winter months. if your home is improperly inflated, then declare their pumped into your house will be released and your AC will have to work harder to cool down your home. Weak insulation is often a problem in older homes, so if it takes a long time for your AC to cool down your home, you might need better insulation. Insulation is a big project to fix yourself so you might want to call a professional if you want to get this fixed.

All of these factors play a big role in how long it takes to cool your house. Consider all of these things when you’re having trouble with your AC. If you think that none of these things are the issue and you might want to call a technician to take a look at the AC that you’re using. You also might want to consider getting a better form of AC if you’re having trouble with your window unit or your evaporative cooling unit.

Now that you understand what it takes to cool your house, you can keep a certain amount of time in line when we’re using your AC. You should also keep in mind closing your drapes, getting blackout curtains or using a few fans just to help circulate the air in your home and keep the temperature down.
