recommend a mini split installer

@thelake · 08-31-2022, 12:32 AM

Ten years ago, they installed three H2i/hyperheat units for us, two 9's and one 18, still working great.

The Honeywell wireless thermostats rock, being able to control the units from your phone, on-site or while you're away. They also display the current temperatures at each thermostat. No subscription, and the service has been very reliable. You'll need home Internet, the Mitsubishi's create their own wireless network with an adapter that attaches to the inside unit.

Home Energy Products will service them (haven't needed that yet), provide warrantee factory updates at no charge, and clean/maintain them annually or as requested for a very reasonable fee.
We've skipped the last few years, but are looking forward to having them out to clean the inside and outside units, and check the refrigerant levels, etc.

The Mitsubishi's (at least our models, from 10 years ago) will produce heat all the way down to -13, but I usually turn them off once the temps hit the single digits.
We primarily heat with propane (Rinnai's) and use these for supplemental heat in the bedroom, etc.
They're working so hard to produce heat at -13, on those few overnights a year I'll break out the space heater.

Thanks to all who have replied to my query.
I will contact installers to assess exactly what we are able to do. I like the fact that the inside unit will be high on the wall, however, the outside unit may provide issues. Installers will have the answers.
I am not fond of putting in a thru-wall A/C unit as it is in the family room and will take valuable space. That may be the only solution.

We shopped for Mitsubishi hyper heat units this year for our lake house, after having had a system at our main house for several years with great success. At least when we were looking a couple months ago, there were still big supply chain issues on the hyper heat multi-head condensers. So you may have to wait a bit to get exactly what you want. We put it off to next year as a result. The installers ended up giving us quotes this year for non-hyper heat units and also Samsungs as an alternative (which apparently are catching up in technology and features with Mitsubishi). I couldn’t believe the variation in price for the exact same 5-head systems, ranging from around $13,500 all the way to $19,000. It very much pays to shop around on these. I know that reputation of the installer and the quality of the install matters, but not $6,500 when they have the same warranty!

Marc Doyon of Marc Doyon Plumbing and Heating in Rochester installed a split system in my house in Wolfeboro -- two head units, one wall mounted and one floor mounted, and one condenser. He had the best price I found in several years of research, and I couldn't be happier with the system. He does great work and is a real professional, and does a lot of work in this area. The split system cools the lower floor of the house and heats a previously unheated Great Room with a 19 foot ceiling -- works great.
