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 Is VRF Calculated?

    How Is VRF Calculated?

    An air conditioning unit like a ductless mini split system has a variable refrigerant flow or VRF. The criteria for a unit to be a VRF is having several indoor air-handling units and one outdoor condenser or compressor. In VRF systems they call it diversity factor.  That means that if you have a 10 ton condenser unit with 13 indoor units each 1 ton, then your diversity factor is 130%.  That means that you have 30% more capacity in evaporation than condensation. VRF systems can use water cooling or include a three-piped heat recovery system or a two-piped heat pump.

    No matter the VRF system, understanding your refrigerant flow allows you to gauge how effectively your air conditioner or heater uses the refrigerant that travels to the evaporators in each indoor air-handling unit. The better the VRF, the more control you have over each cooling zone, allowing you to set your home

  2. How Does Heat Recovery VRF Work?

    How Does Heat Recovery VRF Work?

    In our last post, we discussed variable refrigerant flow or VRF in relation to air conditioners, but heat recovery systems can be VRF systems as well. With the proper flow of refrigerant, a heat recovery system can send heat towards the rooms in a home or commercial building that need it most. For more open spaces especially, this method of heating is appreciated, as from corner to corner, the area is evenly warmed.

    Heat recovery VRF systems can also sometimes heat and cool a space at the same time, and all from one condensing unit. We’ve discussed this on the blog before, but it never gets less amazing. Instead of having a separate air conditioner and heater, you can get all your cooling needs from the heat recovery VRF system. You could save on the cost of the unit as well as maintenance, as you only need to take care of the VRF system, not two units.

    There’s a difference between heat recovery VRF and heat pump VRF systems, so we wanted to take the time to discuss the

  3. Does Mini Split AC save electricity?

    Does Mini Split AC save electricity?

    You try to budget for your bills ahead of time so you can effectively manage your finances every month. The water bill and phone bill are about the same from month to month, but your electric bill is always a wildcard. It’s either high or really high and you’re sick of it.

    You decided to be more efficient in your electricity usage around the house. That helped reduce the bill to a degree, but not as much as you would have wanted. You had the thought recently that perhaps your HVAC units are driving up your electricity too much.

    You’ve been meaning to replace your rickety old air conditioner anyway. A friend has had a lot of good to say about a split AC system, but you’re not too familiar with this method of cooling. If you switch to a mini split AC, will you really reduce electricity and thus lower your monthly bills?

    Absolutely! As long as your increasing your SEER efficiency as well, more info here: energy savings

  4. Are VRF Systems Reliable?

    Are VRF Systems Reliable?

    Your current heating or cooling system (or perhaps it’s even both) has gotten far too expensive. Not only are you paying a lot in energy bills because your HVAC just isn’t energy-efficient, but the units break down often too. The repairs are getting costlier since the unit’s parts have become harder to come by. Even maintenance isn’t cheap.

    It sounds like you could benefit from a new heating and cooling solution. One option you’re looking at is a variable refrigerant flow or VRF system. You’ve heard some good things, but you’re still undecided. Are VRF systems all that reliable?

    Most definitely, and they’re certainly more reliable than your current tired air conditioner or heater. Here are some ways that you can rely on a VRF system going forward.

    Temperature Control

    Your HVAC units lack precise temperature control. Even if you can tip the thermos

  5. What Is a VRF System?

    What Is a VRF System?

    You’re familiar with standard heating and air conditioning units. Through this blog, you’ve become acquainted with ductless mini split systems as well. A coworker of yours recently told you about a VRF system they got installed in their home, which has you curious. What is a VRF system?

    In today’s post, we’ll tell you all that and more. Think of this article as your VRF systems 101!

    What Is a VRF System?

    A VRF system is short for a Variable Refrigerant Flow system. You may also hear of a VRF system being called a Variable Refrigerant Volume or VRV system. Created in 1982 by a company called Daikin Industries Ltd., VRF systems work in a way akin to ductless VRF systems work much like multi zone systems, because it can handle several indoor units with one outdoor unit.  Mini Split Systems are always 1 to 1 condenser and indoor unit.

  6. Mini Split AC Not Cooling Properly? Tips to Troubleshoot

    Mini Split AC Not Cooling Properly? Tips to Troubleshoot

    When you first got your ductless mini split system installed, everything worked like a dream. Then suddenly you started having issues with the AC. Now it’s cooling sporadically or not reaching the temperature you set. What is going on and what can you do about it?

    Here are some troubleshooting tips for your mini split AC.

    Do a Wiring Check

    If the wiring was faulty from the get-go or has become that way over the months or years since installation, then the mini split AC might not be getting the signals to adjust to the requested temperature. Other signs that you have a wiring issue are the indoor and outdoor unit regularly fall out of communication with one another and heating is just as troublesome as cooling.

    We wouldn’t recommend you go tinkering with the wiring components of your ductless mini split AC yourself. Call your technician and let the

  7. Is VRF Energy Efficient?

    Is VRF Energy Efficient?

    Today, energy efficiency is a major factor that can impact whether we buy a heating or cooling unit as much as–if not more so–the price of said unit. If your current air conditioner or heater is an energy hog, you might consider a VRF split system. Is VRF really all that energy efficient?

    Keep reading to find out!

    What Is VRF and How Does It Work?

    First, let’s begin with a quick recap of what a VRF split system is. Short for variable refrigerant flow, VRF systems rely on refrigerant that travels through a condenser unit or several. As the refrigerant moves, it’s cooled or heated according to the needs of a room.

    The more complex three-piped VRF systems can act as a heater and cooler all in one. Even better is that rather than heat parts of a home or building at one time and then cool them later, a three-piped VRF system can handle both heating and cooling at the same time.

    That’s not the case with a two-piped VRF split system, w

  8. How Far Can You Run Mini Split Lines?

    How Far Can You Run Mini Split Lines?

    You’ve decided to get a ductless mini split system installed. You’re excited for the heating and cooling potential and, most importantly, for the expected monthly savings to your energy bills going forward.

    The day your ductless mini split outdoor condenser and indoor air-handling units will be installed is almost here. You’re wondering if there’s anything you should do to ready your yard before the technicians arrive. After all, how far can you run mini split lines anyway?

    The standard length of mini split lines is 25 feet. Why is that? That’s the anticipated distance between the outdoor condenser and the nearest indoor air-handling unit. In some cases, the space from one unit to another may be slightly shorter at 15 feet, so you’d need a line that’s about as long.

    The longest mini split line you can get is around 50 feet, sometimes double that, but in most situations, t

  9. How Do I Get Rid of the Smell in My Split AC?

    How Do I Get Rid of the Smell in My Split AC?

    Wow wee! You were recently giving your split AC a cursory inspection and you have to admit, the unit smelled terrible. You’re not quite sure how to explain the scent except that it’s very unappealing. You’d like to get rid of the odor, but how?

    Well, first, you have to rule out other culprits. Most split AC units are outdoors, so look around you. Do you have a few piles of yesterday’s garbage near the AC that have yet to be picked up by the trashmen? Perhaps an animal died close by and that’s what you’re smelling.

    Scope out the area and look for alternate sources of the smell. If you don’t find any, then it’s fair to assume it’s your split AC that smells rancid. What exactly is it that you’re inhaling anyway? Well, we hate to tell you this, but it’s probably dead animals or mildew.

    We’ll start with the mildew, as it’s the more pleasant of the two. As the internal parts of

  10. Can You Mount a TV Under a Mini Split?

    Can You Mount a TV Under a Mini Split?

    You’ve had your ductless mini split units installed for some time now and you love how efficiently they heat and cool your home when you need it most. You recently decided to buy a new TV, and since it’s bigger than your old one, you have to mount it somewhere different. Is it okay if you put the TV under your mini split?

    Not if you care about your new TV, which we assume you do. A whole host of issues can crop up when you have the TV too close to your indoor mini split unit, so let’s discuss them now.

    If a Condensate Line Malfunctions, It Could Cost You Your TV

    Ductless mini split units are incredibly reliable, but let’s say the worst happens and the condensate line malfunctions. If so, that line holds moisture, which would then release fluid all over your TV.

    As high-tech as today’s TVs are, they don’t make them waterproof yet. If your TV got soaked with condensate fluid, that could be the end of it.
