Please research the appropriate unit size for your area before purchasing. Above's suggestion of square footage is based on ideal situations where minimal heat is transferred. If the area contains many electrical appliances, windows, or non-insulated areas, your sizing may need to increase above the recommended square footage. Please ask an expert technician for ideal size before purchasing.


  1. Where Is the Metering Device on a Mini Split?

    Where Is the Metering Device on a Mini Split?

    If you own or have owned an air conditioner, then it will include a metering device, also known as an “expansion device”. The same is true of your ductless mini split system, although you’re not sure where the metering device is. Where can you find this device?

    Most ductless mini split metering devices are attached to the condenser.

    If you’re not quite sure what your metering device is or why you need to take care of it, then make sure you keep reading!

    What Is the Metering Device?

    A metering device is a cooling system part that is only in charge of expanding the refrigerant.  There are several types of expansion devices, the fixed ones and the adjustable ones.  Most mini splits use the fixed type the capillary.. This refrigerant, will become somewhat warmer before it travels to the evaporator.

    Some metering devices are more upscale like a thermal expansion valve, also known as a TEV or TXV. The sensing

  2. Do Mini Splits Do Exchange Air?

    Do Mini Splits Do Exchange Air?

    You hear it about it all the time in standard HVAC units: air exchange. This function occurs through an air exchanger, a form of ventilation that requires ducts. As you get ducts built into your attic, the ducts branch off into two grilles. One of these is for stale air exhaust and the other is for fresh air distribution.

    The stale air, which is typically in your home’s upper levels, may also include pollutants and humidity. The air exchanger receives that stale air and then sends it out of your home as exhaust. This controls the warmth in your home as well as makes the air you breathe healthier for you. As for the fresh air, it goes through the air exchanger and comes out the other side as fresh, warm air that’s piped throughout your home.

    If you’re thinking of getting a ductless mini split installed in your home or commercial building, you may wonder if the air exchanger will

  3. Do Mini Splits Work in Cold Weather?

    You’ve done a bit of research into ductless mini splits, and you can confidently say that you know this solution could adequately cool or heat your home or commercial building. The problem is, you worry about the compressor, which is an outdoor unit. It tends to get bitterly cold where you live in the winter. Could the mini split compressor possibly freeze in frigid temperatures or will it continue working?

    Ductless mini splits at a moderate level can handle temperatures of at least 20 degrees Fahrenheit before their performance efficiency begins to decrease. If you have an economy mini split, this doesn’t begin losing efficiency until it reaches 30 degrees outside. Mini splits with a lower ambiance can withstand the lowest temperatures, zero degrees, before efficiency begins to take a hit.

    How do you choose the type of mini split that’s best for you? You have to look at your climate.

    For instance, if you experience mostly mild winters in your

    How to Use Our HVAC Load Calculator

    Here at PowerSave AC, your online ductless mini split retailer, we want to help you make the best cooling and heating choices for your home or commercial building. If you’re thinking about buying a ductless mini split system for the first time, then you may have a lot of questions. For instance, which heating or cooling capacity does your home need?

    We’re happy to answer those questions with our HVAC load calculator, which is available to use for free on our website. Depending on the level of humidity you get in your neck of the woods as well as the temperature, your HVAC load may be higher or lower.

    Going too small is rarely a good idea, as your cooling unit may suck up excess humidity, which can leave your skin dry, not to mention your nasal passages as well. The unit also can’t reach the temperature you want your home to be, so it will struggle all day and night. This can shorten the lifespan of the u

  5. Mini Splits to Cool Your Summer Home

    Mini Splits to Cool Your Summer Home

    It’s the middle of summer, and lately, you’re spending more time at your summer home than your primary residence. The only problem is that it’s been a very hot summer, and your current air conditioning system is not equipped to handle it. Sure, you could always escape to the nearby beach or lake, but that doesn’t help when it comes to sleeping soundly at night.

    Fortunately, you don’t have to spend another sweltering evening sweating and tossing and turning with the kicked-off blankets at your feet. Instead, you can look into a mini split system to cool your summer home.

    What exactly is a mini split? A mini split is a ductless system that replaces traditional HVAC units like air conditioners and heaters. Yes, that’s right, ductless mini splits can both warm and cool a space for optimal comfort no matter the time of year.

    If your summer home doesn’t come equipped with ductwork, that’s no problem with a mini split system. How it works is that a compressor unit goes outdo

  6. Where Is the Best Place to Put a Mini Split?

    Where Is the Best Place to Put a Mini Split?

    You’ve heard that ductless mini splits are more efficient than your standard HVAC heating and/or air conditioning solution, but positioning still matters. You’re researching your options before calling for ductless mini split installation and you want to ensure you select the perfect spots in your home or commercial building for the units to go. Where exactly should you put your mini split?

    Here are some tips for choosing your location:

    • Leave some space: Some of the most gargantuan rooms may require more than one mini split. You’re more likely to see this with commercial buildings than homes. If you do opt to get two mini splits to one room, make sure there’s adequate space between the units, like two inches or more.
    • Window symmetry: Windows let in natural light, but with that light comes heat. If your windowed room is especially warm and you want a mini split to cool it down, try to create symmetry with yo

  7. Can You Put a Mini Split Condenser in the Attic?

    Can You Put a Mini Split Condenser in the Attic?

    You’ve decided you want a ductless mini split system to more adequately cool and heat your home. The only problem is, you’ve heard the condenser has to go outdoors, and you have hardly any room in your side yard or backyard. That has you wondering if maybe you could take the condenser and put it somewhere in the house where you do have the space for it, such as your home’s attic. Is it possible?

    Putting your ductless mini split condenser in your attic is not recommended. To explain why, let’s talk a bit about what the mini split condenser is and how it works.

    The condenser, which is also known as the compressor, is an outdoor unit. Your condenser works in conjunction with the indoor units or the mini splits themselves.

    If your mini split cools your home, then the indoor units will send out warm air, which travels along evaporator coils. Since these coils are cool, the air becomes cool as well while the refrigerant absorbs the heat. Then that refrigerant goes to

  9. Does a Mini Split Have to Be on an Exterior Wall?

    Does a Mini Split Have to Be on an Exterior Wall?

    Your home is a sweatbox. Before you go through one more hot summer day, you’d like to invest in a different air conditioning solution. That brings you to a ductless mini split system, which is appealing for a multitude of reasons. You’ve heard that mini splits can be very energy efficient, which could save you money on your monthly bills.

    The problem is, you’re not sure where you’d put your mini split. Does it have to go on the exterior wall, or are your interior walls an option as well? Allow us to explain ahead!

    Ductless mini split systems are not exclusively outdoors, nor are they exclusively indoors, either. As part of a system, the compressor of the mini split goes outside. The compressor, sometimes also referred to as the condenser, may sit in your backyard or side yard. Through several wires, including the electric line, the refrigerant line, and the drain line, the compressor connects to the indoor part of
