OK, so I really have no idea which section of the forum a post like this goes in, so I'll just file it in "General" for now and hopefully will be able to post its conclusion in "Wall of Pride" later.
My furnace and air weren't working for my house any longer. The previous owner built an addition but didn't bother to upgrade the furnace or air at that time, so the new addition, despite being connected to the system, never heated and cooled correctly. The furnace also started going out this winter... it was tripping on high temp every morning when it kicked on and, judging by the rust that fell out of the thing when ripping it out, it was well on its way to the graveyard anyways.
I am well aware of the Daikin system and its substantial benefits over traditional HVAC systems. We've specified these systems enough in our office and feel so strongly about their many advantages that I decided to install one in my home. I contacted my local vendor and purchased a VRV III-S system with four indoor units.
RXYMQ48PVJU (Outdoor Heat Pump)
FXMQ18PVJU (x3 for the three largest zones which include Bedrooms, Living Room/Dining Room/Kitchen and the new addition/problem zone Family Room)
I'll do all of my own wiring and piping but I did hire a contractor to hang the units and do all of the ductwork. I didn't have any sheet metal tools and even if I did would prefer somebody who could make it more workmanlike that I could.
Now showing is Day 1: The demolition. Not much to see here other than missing mechanical equipment, but thought I would log my progress. The new units are still in their boxes.
For those interested, this thing is going to be hooked up to a dedicated electric meter. One of my chief complaints is how nobody can seem to rate these things, even with AHRI ratings now. (They are based on average configurations so each system is different) We know from clients that energy bills drop, sometime substantially, but I also energy model and it seems there is no real way to model these things with any degree of accuracy. I'm hoping that tracking real-world data will help see what this thing really does.
I'll be posting and updating through the week. I'm hopeful I'll be done sometime next week.
