Why Do I Need a MiniSplit Ductless Heat Pump or Air Conditioner?
There are many people who can actually save some money by installing a minisplit ductless air conditioner or heat pump over installing the conventional ducted split system air conditioner or heat pump. A few of the possible areas where some can use a minisplit ductless heat pump or air conditioner are rooms over the garage where additional heating and cooling is necessary simply because rooms over garages suffer because garages in most homes are not as insulated as is other parts of the home. This usually creates problems with many of the newer homes because I have seen builders who need a lesson in load calculation and properly sizing the air conditioning or heat pump systems for the conditions. I am sure many people will agree especially people who own homes where there is a room over the garage. How many of those people have supplemental heating and cooling by the way of a window unit or portable heater? Many people I would from my observations over the years. Now these people can benefit from the easy installation including lower installation costs of the minisplit ductless heat pump or air conditioner. Other places where minisplit ductless units can be considered for installation are additions to homes and basements where minisplit ductless units are great for dehumidification.
How MiniSplit Ductless Air Conditioners Heat Pumps Work
The condenser at the top and the air handler are very quiet when operating
The minisplit ductless air conditioner or heat pump consists of a condenser and an air unit that is installed inside the conditioned space. The minisplit unit has a line set between the two units (condenser and air unit) just as a typical split system air conditioner or heat pump does however the difference is minisplit ductless is without the ductwork need by the conventional air conditioner and heat pump system. There are some minisplit ductless systems that have a single condenser that works with four different air units inside the structure. Many minisplits ductless systems are inverter duty meaning the compressor inside the condenser will modulate according to the load of the air unit. If the air unit inside needs extra capacity then the compressor modulates to a higher RPM to help with the extra load. Minisplit ductless air conditioner or heat pumps are very efficient compared to conventional systems and they can be zoned easier than conventional ducted air conditioners or heat pumps. The key when shopping for a minisplit air conditioner or heat pump is to ensure you get one that is inverter duty. Some manufacturers offer cheaper alternatives that are not inverter duty and these minisplit ductless air conditioners or heat pumps cost more to operate. No duct work is required as the air unit hangs on a wall in the room where conditioning is needed.
Inverter Duty MiniSplit Ductless Compared to Conventional Split System Air Conditioners and Heat Pumps
So the minisplit ductless air conditioner and heat pumps works much the same way conventional air conditioner and heat pumps work. They use the process of refrigeration to heat and cool except unlike the conventional air conditioner or heat pump the typical ductless minisplit air conditioner and heat pump uses inverter duty compressors to modulate the compressor along with the heating or cooling load. In the conventional split system market there is only one manufacturer producing inverter duty compressors in the split systems and that is Nordyne. Nordyne markets their inverter duty condensing units under such names as Westinghouse, Maytag, and Broan to name a few and these non-conventional ducted split system air conditioner and heat pumps offer efficiency levels as high as 24 SEER
which can match geothermal systems
in efficiency except these systems do not need the drilling of wells or a large body of water to work. These systems are air to air in the condenser and the evaporator so the cost to install these systems is less making inverter duty units the best to install even if they cost a little more than others upon installation. Despite the cost being a little higher upon installation the unit will cost less to operate over time and this is where the homeowner or business owner will save money. The savings will be realized in energy savings
over time because inverter duty systems whether they are minisplit ductless or conventional ducted systems will save money in lower energy bills
