  1. Can Mini Splits Run on Propane?

    Can Mini Splits Run on Propane?

    You always have spare propane tanks lying around since you use the gas for your grill as well as your water heater. While that heater is working just fine, your furnace is not. You could also use a new air conditioner, as you’ve put that off for long enough.

    You’re thinking of switching from traditional HVAC to a ductless mini split system. If you invest in a mini split, will it use propane for fuel?

    No, ductless mini splits do not use propane or any other type of gas. Instead, allow us to explain how a ductless mini split system works.

    The ductless mini split system includes an outdoor compressor or condenser as well as at least one indoor air-handling unit, perhaps several depending on your heating and cooling needs. The condenser and the air-handling units are attached via metal tubing, often copper.

    The air that the air-handling unit receives comes from you

  2. Are Mini Splits Quieter Than Window Units?

    Are Mini Splits Quieter Than Window Units?

    Rattle, hum, whine. You don’t mind the consistent whirring of your window air conditioning unit during the day, but as soon as you try to sleep, the noise becomes unbearable. You end up wearing earplugs just so you can get a good night’s sleep.

    A neighbor recently told you about their ductless mini split system, which provides both heating and cooling. You weren’t too familiar with mini splits, so you began doing a bit of research and you like what you’ve read so far.

    If you were to make the switch to a ductless mini split system, is it going to rattle and hum the same as your window AC does day and night?

    No! For those who are light sleepers and need complete (or almost complete) quiet in their bedroom to fall asleep and stay asleep, a ductless mini split system makes a fantastic solution for staying cool all spring and summer long.

  3. Does a Mini Split Bring in Fresh Air?

    Does a Mini Split Bring in Fresh Air?

    On a cool, sunny spring day, nothing feels better than opening the windows and letting the fresh air in. Your home feels rejuvenated rather than stuffy. Plus, it’s a good chance to give the heater or air conditioner a break for a few hours.

    Well, you want to give your heater or air conditioner a very long break, as you’re thinking of switching to a ductless mini split system instead. Before you decide if a mini split is the right solution for you, you’re curious whether the unit will introduce fresh air into your home each time you heat or cool the rooms throughout.

    That’s not exactly how ductless mini split systems work. Allow us to explain. The indoor air-handling units installed in your home takes in air from the room.  Coolant within the pipes then changes the air temperature by absorbing the heat inside the room.  

    If the air is already hot, such as during the summer, then the coolant converts from liquid to gas as a result of meeting the war

  4. Can You Floor-Mount a Mini Split?

    Can You Floor-Mount a Mini Split?

    You’re very gung-ho about the idea of getting a ductless mini split system installed in your home. You’re especially looking forward to saving more money each month on your utility bills since mini splits are so energy efficient. Yet one area you’re struggling with is where to mount the indoor air-handling units. If possible, you don’t really want the units on the walls or ceilings of your home, as you think their presence detracts from the beauty of the rooms.

    One idea you’ve had is to get your air-handling unit floor-mounted, but you’re not sure if that’s even a possibility. We’ll explore the idea of floor-mounted mini splits in detail below so you can decide whether this is the best installation option for you.  It’s important to note before we proceed however that a “Hiwall” mini split (the one’s sold on PowerSaveAC.com) cannot be installed on the floor, there are special indoor units made for floor-mounts that come in only certain capacities.  Before deciding to do a

  5. How Long Have Mini Splits Been Around?

    How Long Have Mini Splits Been Around?

    You’re very appreciative of the ductless mini split system installed in your home now, but have you ever taken a minute to stop and think of how ductless technology has evolved over the years? If not and you’re interested in learning more, you’ve come to the right place. In today’s post, we’ll go over the fascinating history of ductless mini splits.

    Air Conditioning History

    We can’t properly talk about the origins of ductless mini splits without first discussing where air conditioning comes from. It’s believed that in prehistoric times, the Ancient Egyptians had some form of air conditioning, mostly passive AC. Passive air conditioning controls heat gain to increase cooling without using much energy. That’s right, the Ancient Egyptians were eco-friendly!

    Their means of cooling became famous in prehistoric Northern India, the Middle East, North Africa, and the Iberian Peninsula. It wasn’t until the 20th century that passive cooling w

  6. Can You Paint a Mini Split?

    Can You Paint a Mini Split?

    It’s been a few years since you’ve gotten your mini split system installed, and you’re quite happy with how comfortably heated and cooled your home is. You also love saving money on your energy bills. You’ve been thinking of repainting your living room for a while now, but you keep putting it off. You have an indoor air-handling unit installed in there, and you’re not sure if you can paint over it. Can you?

    That depends! If your air-handling unit has a removable plastic cover, then there’s no reason why you couldn’t take the cover off and paint it to match the new color of your walls. However, you will have to shop for separate paint than what you used for the walls. Most paints can leave obvious brush marks on the plastic or smear before they dry, ruining the application.

    You’ll need spray paint such as Rust-Oleum Universal Spray Paint or Krylon Paint + Primer. We’d recommend

  7. Mini Split Concrete Pad Sizing

    Mini Split Concrete Pad Sizing

    One of the most important parts of your ductless mini split system is the compressor or condenser. This outdoor component contains the refrigerant that converts the air to the appropriate temperature so it can pump through the indoor air-handling unit. At the time of mini split installation, your technician will likely recommend a concrete pad to put your compressor on. This is also known as an air conditioning pad.

    Although it seems like something basic and thus skippable, this concrete pad is very beneficial. The pad prevents the compressor from rattling and vibrating when the ductless mini split system is on and running. This movement can wreck internal compressor components that can shorten the life of your mini split system. Long before that happens, the rattling and/or buzzing that the shifting compressor makes can drive you nuts.

    The compressor pad keeps insects and other critters from being able to easily access your mini split system. The pad also prevents the

  8. What Is Mini Split Inverter Technology?

    What Is Mini Split Inverter Technology?

    Staying current on your ductless mini split options helps you make educated decisions about what’s the best heating and/or cooling solutions for your home or business. In today’s post, we want to discuss mini split inverter technology, which could be just what you’ve been looking for.

    We’re all obsessed with smart technology today, right? We’re always on our smartphones where we can talk to Siri and get weather updates or even hear a funny joke. Smart thermostats let us set the temperature in our home with a voice command and smart TVs can flip from channel to channel via your control. Why not smart ductless mini splits as well?

    Ductless mini split inverter technology is indeed smart. This allows the heating and cooling unit to gauge what level of comfort you need and then work internally to remain at that temperature or very close to it. How? The ductless mini split will either speed up or slow down the converter depending on how close your home or commercial business

  9. How Are Mini Splits Rated?

    How Are Mini Splits Rated?

    You want an efficient mini split that won’t raise your monthly utility bills too high. What kind of mini split rating should you seek?

    To ensure your ductless mini split system works as efficiently as possible, you need to check its SEER rating.

    SEER? What is that? It’s an acronym that’s short for seasonal energy efficient ratio. Created in 2008 by the Air Conditioning, Heating, and Refrigeration Institute or AHRI, many HVAC systems use SEER, not only mini splits.

    The SEER rating of a ductless mini split system tells you how well the heating pump and air conditioner work depending on the season. To deduce that efficiency, you take the mini split’s summertime cooling output and divide it by how much energy it uses during the same season.

    Your current air conditioner has a SEER rating, although it’s probably not a very good one. This is one of those instances where lower numbers represent less efficient units and higher numbers are for more efficient units.

  10. Do Mini Splits Use Freon?

    Do Mini Splits Use Freon?

    Part of your ductless mini split’s maintenance entails the unit being refilled with a cooling fluid in case there is a leak in the system, if not, then there is no need to replace or refill the refrigerant in the system. You wonder if that fluid happens to be freon. In today’s post, that’s exactly what we’re going to discuss. Keep reading!

    What Is Freon?

    Freon might sound like a chemical compound on the periodic table of elements, but it isn’t. Instead, it’s a coolant product that’s owned by The Chemours Company. Freon is halocarbon-based and is used as an aerosol propellant or refrigerant. These freon products encompass chlorodifluoromethane and/or chlorofluorocarbons.

    You most often hear of freon in air conditioning systems. When poured into the air conditioner, the freon acts as the element who transports heat from the indoor unit on to the outdoor unit on the cooling mode, and from the outdoor unit on to the indoor unit on the heating mode.
