I look for things that don’t make sense or (wtf) issues and must confess this one was almost flawless. The only potential issue was cutting the condensation tube too short and allowing it run into the houses foundation. Not a big deal and is nit picking considering the fantastic content provided. Well done!

The leak was probably bottom left of outdoor coil. Those small older Fujitsu’s always split out the bottom in heat mode. Fujitsu had a program for awhile to replace them at no cost.

I ran the HVAC system up until I installed my two Mr Cool DIY units about eighteen months ago. I have a 24K and a 12K DIY heat pump system and they're freaking great. They cool and heat my house as good as my 4 ton HVAC system using about 2/3 less energy usage. I also have a 12K Carrier mini split system in our master bedroom and a small 9K mini split system in our spare bedroom. But we only use those systems on rare occasions.

I installed a 18000 BTU Mr Cool DIY 3 years ago in NE Georgia. No problems with it. It will also act as a heat pump down to freezing temps. It is quiet. I bought it via Home Depot and picked it up at the store. You really need some help running the line through the wall because it is unwieldy and needs someone to pull it as you feed it through the wall. Now they have multi-zone DIY packages available. Good warranty with them. I added an AC surge compressor ($70) to the wiring since we have power interruptions with the thunderstorms here in Georgia.

I like the clear and simple video of your install. FYI I don't believe you should be insulating the the 2 couplings (which you referred to as "valves") together. They should be insulated separately as one is line is going to be hot and the other cold. Bridging them together reduces system efficiency.

@shingw

2 жыл бұрын

Having the warm coupling (liquid line) insulated together with the cold coupling (suction line) does not reduce efficiency. What it does is sub-cools the liquid refrigerant before going into the indoor coil, and it also boils off any potential liquid that didn't evaporate in the cooling coil, protecting the compressor. Liquid going back to the compressor could damage it. The reality is that there is very little heat transfer through those couplings anyway, so it's not really a big deal either way.

This was done by a trusted family business whose founder worked with my father when John Zink made air conditioners.

I've seen these and they look like good products. The only drawback I see with this is the leftover piping that you have coiled outside that is exposed to being kicked, stepped on, dented, squashed and other bad things. Seems like they might be able to have the pipe in removable segments so you don't have to leave so much coiled up.

R290 is propane. All refrigerants have a pressure/temperature relationship. Having the same amount of refrigerant in a smaller amount of copper lineset would increase the pressure and cause issues. This would mean that the homeowner would have to release a percentage of the propane into the atmosphere, which would still hinder the efficiency of the unit and also possibly introduce moisture to the system (which can cause serious issues). There's a reason that technicians charge what they do.

Nice job. The black gooey tape you put up near the hole is probably more to insulate the copper pipes so they don't have water collect on them drip down the pipes.

Try opening the suction valve first, wait then open the liquid second. The expansion valve is behind the liquid king valve and you could risk flooding it with oil. Also, wait to fire the unit up after supplying power for a bit. Let the compressor warm up and boil any liquid off. You could take a good chunk of the life off the compressor slugging it with liquid refrigerant.
