Hi! I'm new here. I searched the threads for information on Mitsubishi ductless mini splits but didn't see an answer to my question. If it has been answered, please point me to the right thread.
I have two quotes from Diamond Mitsubishi installers to install a new ductless system in three areas:
* basement finished this summer
* planned bedroom being built under an existing sunroom (will be connected to existing basement)
* existing sunroom over planned bedroom
The quotes are very close in price, but the equipment to be installed is quite different:
1. Installer ONE proposes to install a Tri-Zone 36,000 BTU Hyper Heat compressor with (1) 18,000 BTU indoor unit in basement and (2) 9,000 BTU indoor units in the sunroom and bedroom. All units will be FH-series.
2. Installer TWO proposes to install (1) single-zone 18,000 BTU FH-series indoor/outdoor combo in basement and a Dual-Zone BTU Hyper Heat compressor with (1) 9,000 BTU G-series indoor unit in the bedroom and (1) 15,000 BTU G-series indoor unit in the sunroom.
He said that it's not possible to use a single compressor. He says that FH-series indoor units make noise when connected to a single compressor.
I looked at the specs on the Mitsubishi web site, and the FH-series appears to be slightly better in terms of heating and cooling efficiency. It also seems to have the latest in added technology (the "i-See" scanning of rooms, for example).
I assume that the difference in number of compressors relates to specifics of my house that can't be commented on, but any insight into that difference would be much appreciated. However, I'd like to know whether anyone can confirm the added noisiness of FH-series indoor units when installed together on one compressor. Also, what's the bottom line difference between FH and G? What are the trade-offs?
Thank you so much in advance for any help you can give me. This is an expensive install on an in-law suite, so I'd really like to spend my money wisely.
