    Unfortunately, though, your split system is barely producing hot air anymore. You’ve tinkered with the included thermostat and even still, the air that comes out is hardly warm. It’s certainly not hot.

    You’re not sure what’s going on and whether you need a new split system. Why won’t your split system heat up?

    First of all, you likely do not need a new split system, especially if you just got yours installed. A split system that won’t produce hot air is a relatively common problem with a simple fix.

  2. Where Are the Coils on a Mini Split?

    Where Are the Coils on a Mini Split?

    All ductless mini split systems have coils. You may have questions about what these coils are, what they do, and where they go. In this post, we’ll answer those questions so you can proceed with confidence and heat and cool your home with a ductless mini split system!

    A ductless mini split system features an outdoor compressor or condenser as well as indoor air-handling units. The condenser is the component with the coils, which are located on the exterior of your ductless mini split system.   

    The coils are bathed by refrigerant aka coolant. Refrigerant is a liquid that’s used in commercial and residential heat pumps and air conditioning systems. Your current HVAC systems are likely to rely on coolant or refrigerant in different ways.

    When refrigerant passes along the outside coil of the mini split system, it

  3. How Much Does It Cost to Recharge a Mini Split?

    How Much Does It Cost to Recharge a Mini Split?

    Refrigerants last forever, however when the stuff is fully expelled, you need to get your mini split recharged. This article will be your guide!

    What Does It Mean to Recharge a Mini Split?

    To recharge a mini split has less to do with your mini split system itself and more to do with replenishing the depleted levels of refrigerant or freon.

    The reason the act is referred to as “charging” is because charging kits or bulk refrigerant containers are favored for the job of replacing refrigerant levels. These units will have enough fluid to charge the refrigerant once.

    This means the ductless mini split system has a full charge of freon.

    How Much Does It Cost to Recharge a Mini Split?

    When the time comes to get your mini split recharged, the service costs $100 to $300. For the expense, you’ll get a pound and a half to two or more pounds of refrigerant added to the line of your ductless mini split system. This could

  4. How Many Heads Can You Put on a Mini Split?

    How Many Heads Can You Put on a Mini Split?

    A ductless mini split system includes an outdoor compressor as well as indoor air-handling units, which are technically referred to as heads. The placement of these heads, as well as their number, can vary depending on the home or commercial building.

    How many heads can go on a mini split? That all depends on the size and style of the residential and commercial properties.

    Where to Put Mini Split Heads – The Factors That Play a Role

  5. How Do I Know If My Mini Split Is Low on Freon?

    How Do I Know If My Mini Split Is Low on Freon?

    Your air conditioning system relied on freon. Although an air conditioner and a ductless mini split system are about as different as they can be regarding how energy efficient they are and how much you’ll pay on your utility bills, both units use freon.

    Freon is a non-combustible refrigerating gas. Refrigerant and oil travel through the system and air passes through the evaporator coil to remove the heat when working on the cooling mode and releases that heat when air passes through the coil on the condensing coil.

    As a necessity in your ductless mini split, you’d like to know when the freon levels in the unit are running low. This way, you can call your mini split technician to replace the freon so your mini split never has to operate without this refrigerant.

    Are there any ways to determine how much freon your mini split has left? Yes, indeed, so let’s take a closer look now.

  6. Do Split Systems Need Re-gassing?

    Do Split Systems Need Re-gassing?

    A season or two ago, you upgraded to a split system air conditioner. Your air conditioning system now includes an outdoor and indoor unit. Both units are connected via a copper tube that can send cold air via an air conditioner or hot air through a heat pump.

    This cooled or heated air will blow throughout your home or commercial office building for the ultimate in comfort.

    A neighbor of yours mentioned getting an old air conditioner regassed. Is that something you need for a split system AC as well? We’ll tell you in this article!

    What Does It Mean to Get an Air Conditioner Regassed, Anyway?

    Regassing is a process where a technician takes the refrigerant (in gas form) from a unit–usually an air conditioner–and replaces it with new refrigerant. This

  7. Can You Install a Mini Split Condenser on the Roof?

    Can You Install a Mini Split Condenser on the Roof?

    You’ve long since wanted a ductless mini split system for your home. Your current air conditioning system leaves dead spots in the house that get quite hot and humid in the summer. On top of that, your AC uses a lot of energy, which means you pay out the nose on your utility bills.

    One of the reasons you haven’t made the switch from traditional HVAC to a ductless mini split system is that you’ve heard you can only mount the outdoor compressor or condenser in your backyard.

    Your yard is rather small, and there’s no room for a condenser out there. However, you do have room on the roof. Can you get the mini split technicians to install the condenser up there?

    While this sounds like a good idea on paper, it doesn’t work in theory for a variety of reasons.

    For one, you’re supposed to safeguard the condenser from the elements as best you can. We recommend selecting a spot for your condenser where it’s under some cover, such as below an awning.

  8. Can I Run Mini Split Lines in the Attic?

    Can I Run Mini Split Lines in the Attic?

    Since a mini split system is ductless, the attic is usually a popular place to get the equipment installed. After all, the attic is out of sight for many homeowners, so you don’t have to worry about wiring or indoor air-handling units taking away from the appearance of your home.

    Can you run mini split lines in the attic? In today’s post, that’s exactly what we’ll discuss, so let’s get started.

    All ductless mini split systems have a line set, which refers to the copper tubing that links the evaporator to the condenser or compressor. The evaporator, in this case, refers to the indoor air-handling units.

    You may worry about the copper lines in your attic, which are very prone to hot and cold shifts that the changing seasons deliver.

  9. How Do You Troubleshoot a Mini Split?

    How Do You Troubleshoot a Mini Split?

    Ductless mini splits are far more efficient than a clunky old HVAC unit such as a heater or air conditioner, but even mini splits have their problems. Scheduling routine maintenance with your mini split technician is the best way to avoid many common issues.

    What if your mini split begins acting up on a holiday or a weekend? Until you can get the technician out to you, you might be able to do a bit of troubleshooting yourself. Here are some jobs you can safely take care of before the pros come out to assess your mini split.

    Replace the Filter

    Your ductless mini split system uses a filter much in the same way your old air conditioner did. Since you were probably used to replacing that filter, it shouldn’t be much of a big deal to extend your filter-changing schedule to your ductless mini split.

    If the filter is black with grime, dust, and dirt, you can be surprised how much that affects the functioning of your mini split. The unit has to s

    How Do You Reset a Mini Split?

    A dazzling thunderstorm just passed through your area. Well, the storm was dazzling until it knocked your power out. Now you’re less than happy. After the breaker was tripped, your ductless mini split doesn’t want to turn back on.

    You could really use it now, as the humidity in your home is increasing thanks to the heat from the storm. What should you do?

    Now is a good time to reset your ductless mini split system. Here’s how it’s done.

    First, turn off your ductless mini split. Even though it might not be getting any power now, that will change after you reset it.

    Next, find your home’s breaker box. The breaker might have a metal or plastic exterior if this is your first time accessing yours and you don't know what to look for. The box should be installed against an exterior wall, and it could be painted so it doesn’t stand out, although not always.

    Once you’ve located the breaker box, it’s time to power down your ductless mini split system by flipp
