Mitsubishi Electric Ductless Mini-Split Air Conditioners

Ductless, mini-split-system heat pumps (ductless) make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions where extending or installing distribution ductwork is not feasible and very efficient new homes that require only a small space conditioning system. Be sure to choose an ENERGY STAR® compliant unit and hire an installer familiar with the product and its installation.

Like standard air-source heat pumps, ductless ac have two main components — an outdoor compressor/condenser and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.

The main advantages of ductless are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air-handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated and air sealed). Each of the zones has its own thermostat, so you only need to condition occupied spaces. This will save energy and money.

Mini-split air conditioning systems are better for the property than some other types of space conditioning systems. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. Most manufacturers of this type of system can provide a variety of lengths of connecting conduits, and, if necessary, you can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a house, but locate the compressor in a more advantageous or inconspicuous place on the outside of the building.

Ductless mini splits have no ducts, so they avoid the energy losses associated with the ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.

In comparison to other add-on systems, The ductless offers more interior design flexibility. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also available. Most indoor units are about seven inches deep and have sleek, high tech-looking jackets. Many also offer a remote control to make it easier to turn the system on and off when it’s positioned high on a wall or suspended from a ceiling.

Energy Efficient

Because there are no ducts, these systems lose less than 5% cooling vs. up to 40% for traditional forced-air systems. Increased efficiencies lower your utility bills.  Select models are even Energy Star Qualified, meaning they save you on your utility bill.


Having trouble with a sun-room, bedroom or addition? Are you paying to heat or cool areas that no one is using today or don’t use the area or room because it is not comfortable?  Individual zoning allows you to heat or cool the areas you want, and not the areas that are not in use.


These ductless air conditioners and heat pumps are comprised of an indoor unit with a few designs from wall mount, ceiling recessed, base mount and outdoor unit, which allows for a peaceful almost noise free inside environment by enabling Precision Air to install louder components like compressors and motors outdoors.


Space saving, copper tubing running through a small 3 to 4-inch opening in the wall or ceiling easily connects the indoor and outdoor units. Refrigerant is cycled through the lines from the outdoor condensing unit to the indoor unit, where the air is quietly distributed to the interior space. Very good for protection and not like a window unit that allows access.


Year Round, Whole Home/Business Comfort. Mitsubishi ac and Heat Pump Mr. Slim provides home and business owners just the right amount of heating and air conditioning needed by installing 1 or more indoor units connected to one outdoor unit.  Indoor units vary by size and style and each creates its own “zone” for comfort, allowing you to heat or cool individual rooms, areas, hallways and open spaces for the perfect indoor comfort!.

I am new homeowner and had never got a heater inspection/tune-up... I scheduled one with Precision and had a great experience. My technician Steve was timely, professional, (funny), and honest. He showed me a few ways to increase the life of my system while also improving the quality of my air and lowering my utility bill. I recommend Precision Air for sure.read more

I hired these guys to service my old boiler and radiator heating system. The unit was made in 1987 so I was expecting to have to get a new unit. While it does need to be replaced eventually I was happy that they didn't make me feel like I had to. They just serviced it and gave me a recommendation for a new one. They seem like honest guys. Thanks.read more

You installed new high efficient gas tank-less heater this winter and I wanted to wait to give a full review. Everything with the installation was very easy from Tim making the appointment showing up on time and being very helpful through our decision process. He did not try to get us to buy with all kind of specials like some of the other companies. One large company would not leave my home unless we signed that day. We had to throw them out all they were concerned with was selling us a heater! When Lou the installation manager came out to do the materials list he was polite and attentive to our needs. The men did not make do or improvise because they had all the right parts and it looks much better than my neighbors who used another local company. Greg did a great install on our oil to gas conversion. I could not believe that small wall hung unit would heat our home. Well it not only heat our home and hot water it reduced our costs a whole bunch! We normally used 900 gallons of oil at an average cost of 3.75 for yearly budget of 3400. This winter we only spent just over $600. Thank you Precision Air for guiding us on our new tank-less heating system and being so professional. read more

Precision Air was professional, courteous and did a great job. Would recommend them to anyone doing a oil heat to natural gas/central air conversion. As is usual there were challenges with an old house and they knew exactly what to do. We're lovin' the nice, cool, allergen free environment on these surprise 90* days!read more

We used Precision Air for a new/replacement installation. Precision Air was one of four installers that we met with and received pricing from. They were not the cheapest of the quotes but we chose them based on all factors. The entire process from the initial phone contact to the completion of my PECO rebate forms after the installation was handled with friendly professionalism - almost as though we were a friend of the family (we were not). And although they were not the cheapest of those interviewed, they gave us the most value for our dollar and their cost was well under (less than half of) our highest quote for a comparable system.read more

Precision provided us with a perfect experience. They right sized a central air conditioning system for us. The system is quiet and what an upgrade from the older single stage units. The Precision team that estimated the job, planned the job and the install team all exhibited the highest level of professionalism. Everyone involved was considerate, polite, and perfectionists. They left our house in a clean condition. We simply could not be happier. They truly care. Very nice in this day and age.read more
