What Features to Consider When Buying a Ductless Air Conditioner?

When looking for the best ductless air conditioner, there are critical factors you need to have in mind in order to get the unit that would suit your home. To help you out in deciding, here are some of the considerations you should take before buying a ductless AC system.

Power/BTU. The higher the BTU, the larger the area the model can cover. You can quickly see the size a unit covers on the description of the item. Make sure to check this so you will have an easier time selecting the specific unit that your home needs.

Modes. All ductless air conditioners have a cooling mode. However, there are those models that raised the bar and offer additional functionalities like fan mode, heat mode, dehumidify mode, and an automatic mode, which picks the ideal temperature setting to keep your room most comfortable.

The number of zones. Some homeowners have lots of rooms to cover in their houses. It’s a great thing that there are multi-zone units that allow you to cool several rooms at a single time. They are still affordable and most of these types can cover up to four to six zones.

Energy efficiency. Of course, you would want to find a unit that would help cut your electricity costs while still keeping your home cool and comfortable.

Compressor. There are two types of compressors used by ductless air conditioners nowadays – the rotary and the inverter compressor. While the rotary compressors are widely-used, the inverter compressors are newer. Thus, they are more energy-efficient and help save electricity as they don’t switch on automatically using full power.

Timer. If possible, try to look for a unit that has a programmable timer. The temperature may vary throughout the day but at the same interval. By having a programmable timer, you can quickly set the specific temperature you want for a certain time of the day.

How to Install a Ductless Air Conditioner

One advantage of a ductless air conditioner is that it’s easy to install. And we have prepared a simple and quick guide on how to install one.

1. Prepare all the tools and materials needs.

For the tools, we’ll be needing the following:

  • Drill or driver
  • Fairing tool
  • Adjustable wrench
  • Rotary hammer
  • Level
  • Hole saw
  • Torpedo level
  • Pressure gauge and nitrogen
  • Vacuum
  • Wire stripper

And prepare the following materials too

  • Metal C Clamp
  • Brass nut
  • Ductless mini-split system
  • Copper PVC pipe
  • Condenser wall brackets.

2. First things, turn off the electric source first.

3. Get your mounting bracket and level it against the wall. Mark the screw locations on where you will bore a hole. This will be for the electrical cable, condenser discharge line, and refrigeration lines.

4. Get your rotary hammer and masonry coring bit. Then from the inside, bore a hole on the wall. Continue to drill to the outside of the wall.

5. Screw the mounting bracket to the wall.

6. Install the AC unit to the wall bracket. Now, pass the refrigeration line and condensate discharge through the hole on the wall.

7. Attach a vertical chase below the hole in the wall. You need the chase to hold the refrigeration lines, condensate discharge, and electrical cable.

Pull the condensate discharge line a few inches out of the ground by attaching a PVC pipe. Use duct tape to secure the line to the pipe. Use a metal C clamp to fasten the lower portion of the pipe to the chase.

8. Bend the refrigeration line down to the chase. Use the wrenches to remove the compression fittings on the copper refrigeration line.

9. Slide a brass nut to the new copper tubing. Then flare the end of the rubber tubing using a flaring tool.

10. Get the tubings to the flared end of the refrigeration line coming from the AC unit. Tighten the nut to attach the copper tubing to the refrigeration line. Do the same to the remaining refrigerant lines.

11. Get your outdoor condensing unit and position it adjacent to the chase.

12. Again, tighten the compression fighting on the refrigerant line using two wrenches. Then wrap pipe insulation on each line.

13. Run a nonmetallic cable on the condenser unit to the indoor air conditioning unit. Pass it through the hole on the wall.

14. Put the cover on the chase to hide and protect the cables and lines.

15.  Make all the necessary electrical connections at the AC unit and condenser.

16. Do a pressure test using nitrogen (300 lbs per square inch).

17. Vacuum out the nitrogen. Open all the valves to release refrigerant into the system. 

18. To test if the AC is working well, turn on the power source.
