    What Does a Mini Split Look Like on the Outside of the House?

    Once the last snow of the season melts, you’re outside every weekend mowing your lawn, pruning your landscaping, and tending to your garden. You care just as much about the exterior of your home as the interior. After all, when people drive by, it’s the outside of your property they see.

    This year, you’ve toyed with the idea of getting a ductless mini split system installed. However, you worry that the inclusion of the system on your property would detract from the look of your home’s exterior.

    What does a mini split look like on the outside of the home?

    Well, we think you’ll be happy to learn that it doesn’t look like much. Ductless mini split systems include air-handling units and a compressor or condenser. The air-handling units, whether you have one or several for your home, all go inside the house.

    The compressor is the outdoor part of your ductless mini split system. It’s about as large as an outdoor air conditioner as part of a central air unit, but

    How Much Will a Mini Split Save Me?

    Ah, saving money. It sure is nice, right? You try to cut back wherever you can in many areas of your life.

    You wish you could do something about your energy bills though, as those are higher than you’d like. You try to turn off the lights when not in a room and unplug devices you’re not using. Is there more you can do?

    Yes, there is. By switching to a ductless mini split system over traditional HVAC such as heaters or air conditioners, you can see some potentially significant savings.

    How much money can you expect to pocket by getting a ductless mini split system installed? That varies depending on the square footage of your home, what you currently pay for heating and cooling, and how much heating and cooling you need in British thermal units or BTUs and the cost per kW in the area that you live.

    According to mini split manufacturer Mitsubishi, ductless cooling and heating can

  3. How Far Can a Mini Split Be from the Condenser?

    How Far Can a Mini Split Be from the Condenser?

    A ductless mini split system requires a condenser and air-handling unit to work in conjunction with one another. Both units generate cool or warm air. The condenser goes outside of your home and the air-handling units are installed in the various indoor zones where you need the most heating and cooling.

    Precisely how much distance is permitted between the mini split air-handling units and the condenser?

    That’s between 15 and 50 feet.

    The air-handling units and condenser are connected via a refrigerant line. As the name implies, the line allows the refrigerant to flow through the two components so heating and cooling can occur.

    The average length of mini split line is 25 feet, which means that most homeowners select a place for their condenser that creates that much distance between it and the indoor air-handling units.

    If your home is narrower and you can’t make 25 feet of space work, then you might opt for 15 feet from one part of the mini spl

  4. Do You Need a Ceiling Fan If You Have a Mini Split?

    Do You Need a Ceiling Fan If You Have a Mini Split?

    Almost every ceiling in your home has its own fan. On especially sweltering summer days and nights, you rely on those fans to provide cool air. After another heatwave though, you’ve decided you need a better cooling (and heating) solution.

    That’s inspired you to consider a ductless mini split system. Your system has yet to be installed, but you’re wondering if you should still keep your ceiling fans or whether they’d be redundant.

    There’s no need to get rid of your ceiling fans now that you’ve chosen a ductless mini split system. You certainly won’t have to use your ceiling fans as much though, that’s for sure!

  5. Do I Need to Vacuum a Mini Split?

    Do I Need to Vacuum a Mini Split?

    You vacuum your carpeting, sure, and maybe your upholstery from time to time too, especially if it’s dusty. Yet your ductless mini split system? You weren’t aware that you had to vacuum that as well. Do you really?

    Yes, vacuuming a mini split is crucial before refrigerant release. That said, it’s not a job you have to do yourself if you don’t feel comfortable. You actually need a special vacuum for this type of job and it does not need to be done regularly like your carpet would.  Your mini split technicians will gladly take care of this task for you.

    Let’s discuss what the process entails now.

    The technician will use tools such as Allen keys, a mini split adapter, HVAC gauges, and a vacuum pump. If not HVAC gauges, then your technician may utilize a micron gauge instead, but the tools are not interchangeable.

    The technician will begin by inspecting the tools they are bringing to the job to ensure they are in working order. The valves will include t

    Can You Put a Mini Split Over a Window?

    In the summer, a window air conditioner in nearly every opening is a common sight in your home. Recently, you sat down and evaluated how much you’re spending on utilities. You can’t believe what electricity suckers all those window units can be!

    You need to do something about your HVAC spending. After a bit of research, you became interested in ductless mini splits, which you’ve heard can save you money on your monthly electricity bills.

    Can you put a mini split over a window like you would your air conditioner? Not exactly, because a ductless mini split system doesn’t work the same way.

    Allow us to explain the parts of a mini split. The outdoor compressor or condenser sits in your yard. Connected to the compressor is a series of indoor air-handling units. These units release the cold air in the summer and then warm air in the winter.

    The air-handling units have evaporator coils that are cold due to the refrigerant in the system. When warm air enters

  7. Can a Mini Split Freeze Up?

    Can a Mini Split Freeze Up?

    You know that an air conditioner can freeze if it doesn’t have enough refrigerant. Since your ductless mini split system is capable of cooling (as well as heating), you wonder if the unit could suffer the same fate.

    Although ducted and ductless systems are usually as different as can be, this is one thing they do share. Indeed, then, your mini split system could freeze.

    What Causes a Mini Split to Freeze?

    Let’s explain one scenario in which a mini split freezes in more detail.

    Mini splits, like air conditioners, use refrigerant. Refrigerant is a type of chemical compound that can absorb heat and then send cool air through the unit. In the case of your mini split, those units are indoor air-handling units.

    If you have a leak anywhere in your system this could potentially cause the pressure within the mini split system to drop quite rapidly. The

    Perhaps you’re bidding adieu to your home after having many happy memories there. You don’t want to leave your mini split for the next homeowners to use, especially because it’s made such a difference in how comfortable your home is, not to mention you love saving money on your energy bills.

    Is it possible for you to move parts of your mini split to accommodate your new home setup? What about the whole thing?

    Indeed, you can! That said, you can’t do it on your own. You’ll have to contact your mini split technician to come to the house and help.

    The components of your ductless mini split system can be heavier than they look. For instance, did you kno

    What Is the Best AC Temperature to Sleep?

    You usually give your air conditioner a break overnight since the temperatures are low enough that you can sleep comfortably without it. Tonight, though, is different. You’re at the beginning of what will be a multi-day heatwave. You suspect you’ll have to sleep with your air conditioner on for the next several nights.

    You’re not happy about this, and not only because it’s going to cost you more money on your utility bills. You also have no idea what temperature to set the air conditioner so you don't turn into an ice block overnight.

    What is the best AC temperature to sleep soundly? According to Medical News Today, the answer is somewhere between 60 degrees and 67 degrees Fahrenheit. Most people prefer temps up to 65, others 67. You might prefer a cool room that’s closer to 60 degrees, or maybe it’s your spouse or partner that does.
