I'm on Long Island, so I imagine you wouldn't know the going installation rates for my area. However, would you have a ballpark figure of what it might have cost you if your unit was strictly A/C, and without the added insulation? This site has prices for units only: How Much Does a Mitsubishi Ductless Air Conditioner Cost? They list the unit we have (18,000 btu, 26SEER) as $3k, pretty sure we paid a bit less than that, given all our costs. The installation will be the same, I think, on an A/C only unit as an A/C/heat unit. The installation required a 20amp 240 volt service and an exterior electrical outlet within 25 feet (don't ask me, the county said on the permit that it is current county code to have an outlet for servicing exterior heat/cool units). The heat pump box was mounted on the side of the house above the snow line, insulated fluid (refrigerant) cables run up two and a half stories to the attic, across the attic and into the back of the head unit on the wall.

So they were up in the attic anyway. My impression, looking at the bill, is that the install portion was just under a grand. That included two "service visits" as well, at 6 months and a year, to check on the system, clean the 4 filters, etc. 4 ton air conditioner package unitThe electrician was from the same company that put in our 4.8kW solar panels, so I think we got a deal from them.carrier heat and air conditioning units The Fed and state rebates came to about $400, based on the size we were heating vs the size of the house, with the state chunk being the larger.hvac unit 17 review questions Originally Posted by nitram Would you happen to know how many zones? 168 posts, read 266,010 times Originally Posted by Sasha's

I'd only be interested in the cooling units - no heat. 7,748 posts, read 14,728,356 times That is incorrect mini splits come in heat pump form and in fact are really efficient at it. They can produce heat down to 15* and sometimes lower without any additional source.The Perfect Solution to Your Cooling and Heating Problems What is a ductless mini-split system? Ductless systems pump cooled or heated refrigerant directly to wall- or ceiling-mounted air-handling units through small lines. Each room or living space has its own air-handling unit, and each unit has its own temperature control system. A ductless mini-split is comprised of two units: Indoor Unit – uses refrigerant to cool or heat air and quietly streams it where you need it in the living space. Outdoor Unit – has an inverter-driven heat pump that cools or warms refrigerant and sends it inside to an air handler through small lines. When is a mini-split preferable to a central ducted system?

Hot and Cold Rooms Homes Without Space for Ductwork Larger, Multi-Zone Living Spaces When You Have High Energy Costs Why pay to cool/heat your home all year long when you only live in a few rooms at a time? Cooling is up to 40% more efficient than standard systems. Single and multi-zone systems are available to fit any room or your entire home. When You Have Hot or Cold Problem Rooms A common problem with ducted forced air systems – one that can easily be solved by a ductless system. The system senses the temperature throughout the room and makes automatic adjustments. No ductwork is required, so installation is fast and doesn’t require any messy renovation.For Renovations and New Homes Ductless systems only need a 3” opening for two refrigerant lines, control wiring, and electrical connections; perfect for man caves, garages, or any additions. And it’s a life saver for any home that can’t accommodate ductwork. Outdoor units are compact, lightweight, and easy to install unlike outdoor units for ducted systems.

For Allergens and Enclosed Odor Areas Mitsubishi’s ductless system comes with a sophisticated multi-part filter system to reduce odors, allergens, viruses and bacteria from the air as it circulates within a room. With regular cleaning, the filters can last up to 10 years and are easy to clean and maintain. While everyone of the Mr. Slim series ductless splits are lightweight and compact, the M-Series was designed specifically for small and/or tight spaces. Don’t let the small size fool you, it can cool almost any size room with ease and efficiency. And unlike the traditional unattractive window unit, the Mr. Slim indoor ductless split is so small and compact that it continues to by one of the the top choices amongst the most fashionably conscious consumers. The Mitsubishi Mr. Slim P Series offers flexibility and convenience for even the most demanding of commercial and residential spaces in San Diego. The P-Series indoor unit cooling and heating solution is unmatched, it can quickly heat up or cool down even the largest of spaces.

Wall mounted, celling recessed, celling suspended and ducted options are available with this model.Start feeling comfortable today! To help you better understand ductless mini splits, let’s consider some frequently asked questions, and their answers. Doesn’t a window mounted unit serve the same purpose? A ductless mini split requires only a three-inch hole through the wall connections, enabling it to be mounted on any wall, or hung from a ceiling without blocking window light. In addition a ductless split is significantly quieter than window or wall A/C units. Does a mini split cost more than a window unit? Yes, but the smaller indoor evaporator unit provides greater versatility in placement, and the small access hole makes your home safer from intruders. In addition, if a ductless mini split is used only when a room or area is occupied, the savings may equal up to one-half of your normal heating bill.Can mini splits be used to for zoning?A single outside compressor, up to 125 feet away, can be used to feed one or more evaporator units, each having its own wireless, remote control.
