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. How Many Zones Can a Mini Split Have?

    How Many Zones Can a Mini Split Have?

    You’ve had it with your current HVAC setup. All year, your air conditioner or heater blows throughout various rooms, sometimes in spaces that don’t even need it, wasting your money. You want to switch to a ductless mini split system, but something is giving you pause. You have a rather large home or a commercial building which is divided into many zones. You’re wondering if a mini split system could have enough zones for you.

    In today’s post, we’ll talk in more detail about zones, including how many zones you can get out of a mini split. Keep reading!

    What Are Mini Split Zones?

    First of all, what are zones? A zone is any area that’s a contender for an indoor mini split unit. Depending on the home or building, a zone can be an entire room or part of a room. For instance, maybe you have a large warehousing building. The central room has electrical equipment that makes it warmer on that side than the other side. That one room could be considered

  4. How Multi-Zone Mini Split Systems Work

    How Multi-Zone Mini Split Systems Work

    You have an air conditioning unit, maybe even central air, as well as a heater. The problem is, if certain rooms have fewer vents, or if they’re lacking on return units, then those rooms aren’t as comfortable as the other spaces in your home.

    A ductless mini split system can overcome this issue, as you select the number of indoor air-handling units you need as well as their placement and temperature. Single-zone heating/cooling involves but one indoor unit whereas multi-zone mini split systems are somewhat more complex.

    Multi-zone mini split systems include more than one indoor air-handling unit. Many situations call for the installation of multiple units. For instance, in a home, you might have adequate cooling or heating upstairs but not downstairs or vice-versa, so you want a number of rooms to have their own mini split unit.

  5. How Often Should You Clean Mini Split Filters?

    How Often Should You Clean Mini Split Filters?

    When you bought your ductless mini split system, it came with one or more indoor air-handling units. Within each of these units is an air filter. Like you’ve had to change the air filter in your air conditioner or heater before, the same is true of your ductless mini split. How often do you need to clean the filters?

    On a two-week basis, you should access your mini split filters and see if they need to be cleaned. Otherwise, dirt, debris, and even mold can grow on your filters. Also, dirty filters impede air quality and airflow and cause your mini split system to run less efficiently.

  6. How to Choose the Right Mini Split for Your Workshop

    How to Choose the Right Mini Split for Your Workshop

    You have a workshop where you spend a lot of your free time. Perhaps you make projects out of wood, or you engage in metalworking, drawing, sculpting, or any other recreational hobby. Since your workshop is likely a garage or basement, it’s not a very well-insulated space. You tend to feel whatever the temperature is, which can make concentrating on your work difficult.

    You’ve looked into your heating and cooling options and you think a ductless mini split system would be best for your workshop. You can cool or heat the areas that are most uncomfortable and only those areas.

    The problem is, you’ve never bought a ductless mini split before, so you’re not sure which type is best for your workshop. Here are some factors to consider that will help make the decision easier.

    The Size of Your Workshop

    How big is your workshop in square feet? Depending on the size, you’ll need more BTUs or British thermal units per hour out of your mini split.

    Where Is the Metering Device on a Mini Split?

  10. 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
