The ceiling unit is now connected to the outdoor unit with both the line set and electrical cable. The water outlet is connected to a hose that runs down to under the house.

The ceiling plate is also installed.

As you can see, the air filter is in the down position; it has a built in lift that lowers the filter for easy cleaning access. My ceiling isn’t that high, but it’s a cool feature.

Outside, the line set and electrical cables are also installed.

The only thing left is to open the valve on the condenser to release the refrigerant, but I probably won’t do that until I have also installed the master bedroom indoor unit.

And then after a final check for leaks, the pipes can be wrapped up to prevent sweating.

With my new laser infrared thermometer I can measure the temperature of any surface. The attic upstairs goes up to 104F (42C) even though outside it’s “only” 93F (34C)

So I postpone pulling the line set up there until tomorrow morning.

And some other time I might install a gable louver vent in the attic, so that the hotter than outside air can flow out.

The great room AC still works pretty well; the temperature at the air outlet is 55F (12C)

As the upstairs bedroom is fairly small, and there is no neat way to run the lines from the indoor unit to the outdoor condenser, I opted for a ceiling unit. The downside is that is bulky, and heavy. They recommend 2 people to install it, but since I haven’t been able to clone myself and it’s do it YOURSELF, I thought of a safe way to get it mounted. Using a climbing rope which I attached to the 4 hoist points, and a pulley screwed info the rafter, I hoisted the unit up, secured the rope and then climbed up to get it supported with some 2×4’s. Then I could detach the rope and shift the unit into place. Finally it’s secured into the ceiling joists, which air had to add, as it needed 16″ spaces joists, whilst mine are 24″.

There will be a ceiling cover mounted later, but this was the most challenging part.

As I already installed the bracket, putting the condenser in place was relatively easy. Not light, but easy. I used the same technique as they used to build the pyramids; put something under each alternate side and lift it up step by step.

It has a gap at the rear for air inlet and is close to the also already installed disconnect.

The original plan was to get delivery on Friday, but that didn’t happen and was moved back to today, Monday. The shipment was on a large pallet, with 4 boxes. One condenser, one wall indoor unit, one ceiling indoor unit and a box labeled accessories.

I asked the driver if the box accessories contained two line sets ( the copper lines and electrical wires that connect the indoor to the outdoor unit) which was confirmed.

I signed for delivery, hauled the boxes up the driveway and first opened the accessories box. To my great disappointment, it contained only one line set, not two 😞

I immediately contacted the supplier and after going through some questions was told it would be forwarded to the shipping manager for confirmation and sending a 2nd line set.

Hopefully that will arrive this week, so I can install the 2nd line set before I fly back again.

To be continued.

The new dual zone air conditioner that was supposed to be delivered Friday was delayed until Monday (don’t ask).

But I still needed to get some materials anyway, like a dual circuit breaker ( the old one was a 110V ) and new cable to run from the circuit breaker to the disconnect.

I also bought and mounted a bracket for the condenser. The lines for the master bedroom indoor unit will go under the house. The unit for the upstairs bedroom will be a ceiling unit, and the lines for that one will run from the upstairs bedroom, past the upstairs bathroom, down into the technical room. And there it will go through the floor, close to the grey disconnect box.

I just arrived at Ozuye (after a comfortable premium comfort flight thanks to my brother Arne) for some HVAC repair and installation. As with any job, having the right tools is essential, so on arrival I had the following tools delivered by Amazon;

On the left is a torque wrench. That allows nuts to be tightened with the right amount of force. In the blue case is a manifold gauge set, which allows me to measure the pressure on the HVAC lines.

Top right is a leak detector device, that can be used to look for leaks in the HVAC lines; it beeps when the nozzle is close to a leak.

Bottom right is an infrared temperature gun, so the temperature of the indoor units can be measured. It will also be useful to trace hot and cold spots in the home, as any surface can be measured from a distance.

The AC in the great room still works ok; I managed to get the temperature down to 75 from 85 within about an hour. But I suspect there could be a leak in that unit too, just less bad than in the master bedroom.

Tomorrow (Friday) the new dual zone AC unit will be delivered, which I will use to replace the one in the master bedroom and a ceiling unit will be installed in the upstairs bedroom.
