Hi folks. Here I am again to seek your advice/assistance. Here's the situation: We're having some remodeling done by a contractor(he's also an electrician). We like to sleep in a cold bedroom but don't like "refrigerating the rest of a 2200SF house, so one project was going to be mounting an A/C in the bedroom wall. He was going to charge us $600 for this (not bad, for the framing, sheet rock work, and moving an outlet for the power). I found several choices of A/C units for about $400, so $1000 total for the job. Asking your (and others') advice about which brand was best; several advised to get a mini split instead. I talked with my contractor about it and he told me that he hadn't done one before, but thought it shouldn't be too difficult and would be less $$ for the install since there was no framing or sheet rock. He said he would hire an HVAC person to do the refrigerant part of it. So, after a bit of research I purchased a Senville LETO 9000 BTU unit + a wall mount bracket (a pad wouldn't work where we're putting the unit) + a "line hiding" cover set - around $700 total. This still should put us in line with the original cost. Now; the problem: My contractor looked at the unit and said that it comes with no wiring harness to go between the units. (I called the company, and they don't even have one optional). The wiring diagram is not very helpful, and he said that now he is apprehensive about doing the install. He said that there are both low voltage and high voltage connections to connect the inside and outside units. He said since he's only making $300 - $400 for the install, he doesn't want to risk hooking up a high voltage to a low voltage connection and burn something out and have to buy me a new unit. Understandable. I haven't checked locally yet with any HVAC companies, but several reviews said it cost them around $1500 for the install on their unit. I DO NOT have that kind of money left! Help! :help: Anyone on here familiar with Senville units? Can you tell me exactly how/where to hook up the wires? Looks like I may have to install it myself, and hire HVAC to do the refrigerant part (BTW - it has a Toshiba compressor, and comes "pre-charged"). Any installation tips? Thank you for any help/advice/assistance you can give.
