Heat Pump and Mini Split BTU Per Square foot Recommendations that will Help you Choose the Correct Size Mini Split.
Ductless split systems can offer a number of huge advantages over traditional style air circulation tech. These types of A/C units can easily handle the process of air-conditioning for an entire home or a series of commercial locations along the way. As innovative cooling devices, they remain extremely efficient and they can deliver a quiet airflow that is also great for conserving energy.
One of the big changes with using one of these systems over other types of air-conditioning systems however is that they need to be properly sized to appropriately provide air-conditioning for the spaces where they are installed. If a unit is undersized this can lead to problems with cooling the area. If the unit is oversized it can often lead to issues with temperature regulation and airflow. Getting the optimal size for a mini split A/C unit will help to ensure an interior space can be properly temperature regulated and as efficient as possible.
How do these systems work?
Split systems are designed using an outdoor unit as well as a series of indoor units called air handlers. The outdoor unit contains the compressor as well as the condenser coil. Housing these items outside insurers that the interior of your home stays quiet when the mini split is operating.
With the evaporator coil left inside the indoor unit the airflow can disburse throughout the home through every evaporator coil in each of the inconspicuous indoor airflow units. These units are very accommodating for the wall and just a 3 inch diameter hole wall is required for the copper tubing and the electrical wires that can hook up each element of the system. Because the piping does most of the work and the unit is pumping from outside, the whole system is extremely quiet and also much more efficient than any indoor air conditioner.
Each of the indoor units can be programmed on their own so that they can keep a certain temperature. All of the units can also be collectively programmed to run through one single point and keep a consistent temperature throughout the home. It makes much more sense however to control each unit individually or through a remote control as it can lead to greater cost savings by not having to cool down every part of the homelike central air generally has to do.
The big advantages of mini split air-conditioning systems:
These types of ductless air conditioning systems can, some huge advantages especially during the process of installation. With central air advanced ductwork needs to be installed in order for the system to work. This can often involve an extensive remodel of a home as well as the installation of a full-blown programmable thermostat. A mini split air-conditioning system can be installed without having to run any of this ductwork and with an extremely miniscule running of piping and wiring throughout the home. Some of the other advantages that can come with the installation of a mini split air-conditioning system include:
Their incredible efficiency: Because you can control the temperature in each part of the home it’s possible to regularly lower your energy bills and optimize the temperature in each room you are commonly in.
Creating zoned areas of the home: If you want to extensively cool down your bedroom for sleeping or keep one room warmer for activity, it’s possible to change the temperature at will and customize zones throughout your home based off of the way you are using every room. This can lead to a wonderful level of customization ensuring that your home and each member of your family will be in the perfect temperature in each room.
Very quiet: Each of the indoor units for one of these systems is virtually silent when they are in use. As most of the air-conditioning unit sits outside and behind one of your insulated walls, the noise that you hear from each one of the indoor units is just airflow. There are no loud pumps, compressors or other noises that you may have experienced from other types of mini air-conditioners.
A cost savings for installation, purchase or rental: when you decide to rent one of these units or purchase it out right, you may want to consider that a mini split air-conditioning system is considerably cheaper than any type of central air system to purchase and for all of its installation costs. You will gain cost savings in terms of efficiency and you can order and then install the entire system throughout your home at a much cheaper price than you would pay for many other types of air conditioning systems.
No need for exhaust hoses: we some types of air-conditioning systems you may be forced to deal with an exhaust hose or other types of external items leading out of your air conditioning unit. Rather than having to regularly deal with these types of problems and eyesores within your home, the internal units with a mini split ductless air conditioning system are much cleaner and more visually appealing. There is no need for an air conditioner to detract from your home décor!
Why is it so important to have the right size pump for one of these systems?
Any ductless air conditioner needs to have the right level of efficiency performance in order to properly cool down rooms throughout your home. If the sizing of the pump within your unit is too large or too small the entire air-conditioning system will never operate with efficiency. When the system becomes sized improperly, this can lead to the pump having to work overtime in order to cool down the house or it will consistently cycle on and off in order to maintain the temperature. When the pump gets too powerful this often leads to an airflow that is not consistent enough and this makes temperature regulation near impossible. Sizing the pump for your space and a number of other factors is extremely important.
What remains equally important is the way that the indoor unit is mounted. If your pump is mounted in the wrong location or the entire installation was done incorrectly, this can lead to a number of efficiency barriers as well. Systems need to be installed in an area of the home where they can pump air to each one of the indoor aspects of the air-conditioning unit. With the proper placement this can cut down on the total amount of work that the pump has to do and ensure that you can get a much quieter and more efficient experience over time.
When your pump is sized incorrectly or installed in the wrong area throughout your home this can lead to a number of expensive problems. Relocating your pump or even replacing your pump due to it having to work overtime, can often mean paying for full installation all over again. As well as risking the chance that you could severely damage your air conditioner, there is also the chance that you could be paying an extensive amount of money in your energy bills because of the improper installation. Working with a professional air-conditioning contractor for the installation is one of the best ways to ensure that you end up with the right size pump and to make sure that installation is done appropriately.
The factors that relate to the size of your pump with your AC unit:
There are many factors that should be considered when you are attempting to appropriately size a Mini Split ductless A/C unit. Depending on the type of home that you have in the area that you need to cool down, any professional AC installer will need to consider some of the factors associated with your home and then eventually perform calculations based off of the square footage as well. Some of the biggest factors that any professional will consider beyond the amount of space that you need to cool include:
Insulation levels: many air-conditioning contractors will do a quick check of your insulation. If you have a fairly new home or you have recently redone your home, there’s a good chance that the insulation within the walls has been done to standard. Brand-new insulation in the walls will help to improve the efficiency of each air-conditioner in every room. Making sure that less of the cool air can escape, you can enjoy better temperature regulation as well as the chance that you may not need as large a pump to cool the home. Some air-conditioning professionals may even recommend for you to upgrade your insulation before installation so that you can improve the efficiency of the unit.
The number of doors or windows in each room: doors and windows in rooms can often lead to a bit of inefficiency when it comes to cool air escaping. Ideally, a room will only have just a few windows and mostly insulated walls. Basement areas can often be much easier to cool and they require far less energy for example. If you have large spaces that are filled with doors and windows, this can significantly upped the number of air handlers that may be required and the power that is required from a pump to cool the area. If you have got windows and doors which are considerably old and uninsulated, this can also continue to drive up the requirements. Some contractors may ask you to upgrade your Windows or install weatherstripping along your doors to ensure that less cool air will escape over time.
The amount of sunlight in a room: if you have skylights or a room that is particularly sunny, this can drive up the cost of cooling and the need for a larger pump within that area. Any air-conditioning technician will check into the light levels within any room based on the time of day. Rooms that capture more sunlight often require a little more energy to cool down. You can often save on this amount of money by installing blackout shades and more to make your air conditioner more efficient. Any air-conditioning contractor however will need to prepare for situations where the shades may be drawn and you want to cool down a room even in full sunlight.
The function of each room: making sure that you can still cool down a room as you are entertaining is very important. Air-conditioning contractors will often look at the floor plan within your home and what you would typically use each room within your home for. If you have a kitchen space in living room that are close by for example, the BTU rating will have to go up for both of these rooms so that you and your family can stay cool even while the oven is on. In most living room spaces or entertainment rooms, the BTU requirements for the pump are also overestimated to ensure that if you had six people in the room at one time, the room could still stay cool. The rating for a bedroom that typically only has one or two people in it is often estimated to be considerably lower than some of the high-traffic areas of your home. The function of each room will definitely going to the calculation on the size of the mini split ductless air conditioning system that you will need in your home.
The number of air handlers you would like: each air handler can add to the cost of the installation as well as the size of the pump that you may need. If you have a larger home however it can be a good idea to consider getting one of these at least on each floor. There are some individuals that even recommend getting them in each room depending on the size and square footage of the rooms you have in your home. Each air handler can cover quite a large area with its cool air but if you regularly closed doors within your house and your home is extremely well insulated, it is likely that you may need one in some of your larger rooms. And air-conditioning professional can often make recommendations to the size of the pump that will be needed to appropriately cool your home and split the air across each one of your air handlers.
The size of the area you want to cool: You may decide that you would not like to cool off your entire home but rather the main rooms that you go in. This is entirely possible with a mini split ductless air conditioning system. The only other way that you can achieve this type of system is when you use a window style air conditioning unit with your home. With the help of a mini split ductless air conditioning system you could cool down, your living room, your office, your bedroom or even your entire home. Additional air handlers can be added over time but it is important to keep in mind you will need a pump that can handle the extras and you can make the process for a large pump and just a few air handlers very inefficient. It’s a much better option to instead commit to cooling your full home or remaining extremely sure for the area you need to cool down.
Working on calculations for size:
Mini split ductless air conditioners often have a lower BTU rating then you may be used to seeing from most types of window air conditioners. This is because they work much more efficiently at piping cold air throughout the home. While some window air conditioners can cool down just one room with 10,000 BTUs, it is possible for a mini ductless system to cool down almost the entire floor of your home or even a small condo. Some of the basic calculations for square footage and BTUs that are required are as follows:
350 square feet = 9,000 BTU Minimum
500 square feet = 12,000 BTU Minimum
750 square feet = 18,000 BTU Minimum
1000 square feet = 24,000 BTU Minimum
1250 square feet = 30,000 BTU Minimum
1500 square feet = 36,000 BTU Minimum
Of course these estimates can change considerably based off of some of the other factors that we mentioned. If you have a thousand square foot home that has lots of natural light and many Windows, it’s possible that your air-conditioning contractor may recommend that you upgrade to a 30,000 BTU unit based off of some of the signs that they might see in their walkthrough. If your home looks extremely efficient or you only want to cool down a part of the home, it’s possible that you could move down to a smaller unit covering 750 ft.² or 500 ft.² within the home.
Choosing single zone or multi zone:
Single zone units within a home are often reserved for smaller homes as well as unconditioned spaces as a supplement to the existing cooling system. A mini split ductless system in a single zone formation is not the type of unit that you can easily convert later on. Ultimately the pump size that is installed will be designed for this single outdoor unit and an indoor unit. The only way to upgrade this system to a multizone unit is to reinstall an entirely new pump or even install a second system that can handle the other parts of the home. Single zone units are primarily used in small spaces but they can be some of the most efficient and affordable multi split ductless AC systems available today.
A multizone system has the same idea but with the option to create up to eight indoor zones within your home. The single outdoor unit will handle the process of providing you with consistent cool air and the chance to control up to eight indoor units for temperature control in every room of the home. This multizone system has become a favorite for many family homes because it remains extremely efficient and everyone can get the ideal temperature that they are looking for. Multizone systems often require larger pumps especially if eight indoor units will be required throughout a large home. The big advantage that comes with these units however is that you can completely turn off some of the indoor air systems to save on energy while still effectively cooling other zones throughout your home. If you have a spare bedroom for example, you could easily close the door and turn off the unit in that room providing you with an ongoing cost savings in cooling your home. This is something that is not available from any type of central air unit today.
