Re: Air Conditioner Installation


You will need to vacuum your inside unit before you open the K-valves
and let the r410a in. You don't want any air or moisture in the lines
when you release the refrigerant.

No big deal. You can buy a vacuum pump on ebay for $20. You will
hook it up thru your manifold and watch it overnight and then see if
it holds the vacuum, which indicates whether you have any leaks.

I will try and do that thing (keep you informed).
The model I chose is an AirLux 18500 Btu/hr. It uses about 1.25 kW. and
gives some heat, when the outside air is not much below zero Celsius. It
will NOT completely heat my old house but should be pretty good for Air
conditioning in summer. My existing baseboard heaters will continue to
provide the "heavy lifting" in midwinter when outside temperatures are
sometimes as low as -40 deg. (C or F, of course).
Airlux makes their stuff in China and I bought mine from the site below.
I found them through eBay and service and advice has been excellent so far.
I only hope the thing actually works as advertised but their approval rating
is very high. Here is one way to contact them should you so wish
http://www.airlux.ca/index.asp. They make pure air conditioners as well as
the heat pump I bought. Other heat pumps range from 9000 Btu/hr to 24
Btu/hr. My unit cost about C$1000 and a further $200 to get it from BC to
Ontario.
The problem of getting it installed continues. I found another local
company who can handle the r410a refrigerant and they looked at the job and
quickly came back with an estimate of $1250, which I think is too much.
That quote also required that I get a separate quote for running 3 wires for
the 230 V from my service entrance to the outside unit. I can easily do
that myself. I haven't decided yet but I suspect I will attempt the job
myself. My only real concern is that the inside unit is quite large (4 ft
long 13 inches deep and about 1 ft high) and is quite heavy (I'm getting old
and feeble!). I will also have to drill a 2 inch hole through the house
wall which consists, from the inside, of plaster; horsehair stuff; laths;
roughly 12 inch square logs chinked with cement mix; laths; clapboard; soft
board insulation; more laths and finally aluminum siding. Might be fun. No
doubt I can rent a suitable drill somewhere nearby.
This system comes pre-charged and does NOT need vacuum pumps and pumps to
charge the thing with refrigerant unless pipes longer than those supplied
are needed. Looks fairly simple.

I have bought a modern split Air Conditioner/Heating
I've been considering a mini-split heat pump to heat/cool
my home office without the expense of heating/cooling the
entire house.

I'm curious what make and model you selected. Also the
approx installation costs. Please do keep us posted and
the best of luck finding a good installer.
