Dual Mini Split Troubleshooting
Comments (21)https://www.airconditionersductless.com/ The ductless mini split has many terrific advantages for both homes and businesses: high energy efficiency, zone control, less dust and dirt blown out from ductwork, and flexibility for buildings both new and old. One advantage that doesn’t often get brought up: because there are multiple air handlers—the small units placed in different rooms around the house—rather than the single one used in standard central air conditioning, if one of the air handlers fails to work, it won’t affect the others. A house or commercial building doesn’t have to lose all its heating or cooling; only one zone is affected. Of course, there’s still a problem—a failed air handler! If you have an air handler that isn’t sending out heated/cooled air or isn’t turning on at all, you’ll definitely want that fixed. Here are some of the possible reasons for one of your ductless mini split indoor units to stop working: It’s actually working fine: the batteries in the remote that are the problem This is a common mistake. If you can’t get the wall unit to turn on, or to changed temperature, the first thing to check is the remote you use to operate it. Put in fresh batteries and see if that gives you back control. A broken blower fan Each of the wall units is a mini air handler containing its own blower fan and refrigerant coil. Stress on the blower fan motor can eventually cause the motor to burn out, or it may suffer from an electrical fault. You’ll need professionals to fix this. In some cases, it’s less expensive to have a new unit put in. (There’s another advantage of a ductless system: they’re modular!) Broken conduits The wall unit connects to the outdoor cabinet through a set of conduits that pass through a hole in the back of the wall. These consist of refrigerant, power, and condensate lines. If a leak or break develops in any of these lines, the wall unit may either lose power or lose the ability to condition the air. Frozen coil Like the coil in a standard central air conditioner, the coil in a ductless mini split unit can freeze over for a number of different reasons, such as a loss of refrigerant or too much dust across the coils. This is less frequent in ductless mini splits (they don’t have as much dust getting into them) but it can happen. If you check on the unit and see a frozen coil, call for HVAC professionals. Don’t try to scrape the ice off, since that won’t fix the problem and may damage the coil. If you have multiple units failing at the same time, then you probably have problems with the outdoor unit. Don’t hesitate to call for HVAC experts to look into this and fix it.PRO...See MoreCan you paint the covers to ductless mini-split systems?
Comments (7)Ok let me restate my questions: Do these units have completely removable covers that aren't attached to the electronics, or are the electronics integrated into the cover? Would painting the cover interfere with any sensors or controls? Are there any models anyone knows of that do have a completely separate cover (no electronics, no buttons, no sensors, etc.) that could be removed and painted without any risk to any part of the unit?...See MoreMini split or central air?

Comments (8)The larger the number of rooms that that you install mini splits in the higher the cost in comparison to a central system. Remember that you need returns for a central system. The choices are to have one in each room, install grates in between the rooms, install jump ducts or under cut the doors. Mini-splits have advantages in some situations. They are inherently zoned, so you don't have to cool the whole house for the dogs or you. Depending on your lifestyle, this might or might not save you money. What is installed in the USA is almost all variable-speed (inverter) equipment so it throttles well to control humidity under low load conditions. If you are on the costal plain, that is more important. It is humid down there. Typically, if a system fails you have lots of other areas to stay comfortable in. That also means that a modest generator will run parts of your system.) For me, a duct system that is outside of the house envelope is a drawback. First, ducts always leak even when new and they never improve themselves. That means everywhere you have a leak it equals a power vent either drawing in outside air into a return or blowing air outside. Keep in mind that also induces pressure differentials in your house so air is sucked in or blown out to balance that. Take a look at the Mitsubishi, Toshiba and Sanyo web sites and see what the mini split kingdom looks like. Keep in mind that in addition to the sterotypal high-wall indoor units, small ducted units (that handle more than one room) ceiling cassettes, horizontal ceiling units are available. You should see them on the web sites. They do cost more and are a little less efficient. Check out the different brands for how their controls thermostats) work if you decide to seriously consider mini splits. You obviously need more quotes given the difference between the two you already have....See Moreductless mini split unit
Comments (10)There was an episode of Ask This Old House a week or so ago where they installed a minisplit for a customer. It was a single-car garage that the customer wanted to use as a home office (it was insulated). I thought the installation was pretty simple: 1. Locate and put a mounting bracket on the inside wall for the inside unit using a couple of screws. 2. drill/cut a 3" hole through the wall and place a sleeve (supplied) inside. 3. Set the inside unit up on the wall. 4. Locate and place the outside unit on a pad (purchased) outside. 5. install the bottom half of a plastic channel (purchased) to hold the wiring and lineset to the side of the house. 6. run and connect the 4-wire electrical line between the two units (purchased). 7. run the power line from the outside unit to the main power panel. 8. run the lineset from the outside unit to the inside unit. Surround the lineset with (purchased) insulation. Snap the top part of the plastic channel in place over the lineset and wiring. 9. Connect the lineset at both ends using the proper flare fittings (supplied). connect a vacuum pump to the service port on the outside unit, pump down and check for / repair any leaks. (You'd need a pro to do this.) Connect the main power line. open the inlet/outlet valves for the refridgerant on the outside unit. (refridgerant is already supplied with the unit.) Turn it on and cool down. Enjoy a frosty beverage of choice. This looks a bit more complicated than it is. But if you're a DIY person, you can do a lot of it yourself. Then an AC guy can come and take care of the lineset and powerpanel stuff....See MoreBobH
