Ductless mini-split heat pumps, also known as &#;mini splits&#; and &#;zoned HVAC,&#; are a type of heating and cooling system that doesn&#;t need any ducts to condition the air.
For this reason, ductless units can be the best solution for home add-ons and renovations that don&#;t have existing ductwork. When extending or installing new duct systems is overly complicated or not practical, ductless units may be the ideal solution.
Larger homes that want more control over their heating and cooling may also prefer the flexibility and convenience of ductless mini-splits. By only heating and cooling the rooms that are in use, you can save a lot of energy and money. And with more control over the temperature, there will be less family quarrels over who touched the thermostat.
A ductless mini-split system is made up of two main parts: the indoor air handling unit and the outdoor compressor/condenser.
The indoor unit, usually suspended from the ceiling or mounted high on a wall, sends conditioned air directly into the living space. The indoor unit is directly connected to an outdoor compressor via a refrigerant line rather than a complicated duct system.
In addition to refrigerant tubing, the indoor unit is also connected to the outdoor unit with a power cable, suction tubing, and a condensate drain line.
Usually, there are multiple indoor air handling units that connect to the one outdoor unit. The multiple indoor units can be independently controlled, but they all use the same outdoor heat pump unit to either absorb or dispense heat.
A traditional central air system, on the other hand, sends air from the indoor air handling unit through a complicated series of ducts, which carry the air into your room.
When you have multiple indoor air handling units, each unit is assigned to a specific area, zone, or room of your home (with the help of a qualified HVAC technician). Your HVAC contractor will help design the zones to create the most energy-efficient and convenient zones for your family.
Typically, you can have as many as four indoor air handling units (four rooms or zones) for one outdoor unit. The number of your indoor units depends on the size of your home and how much heating or cooling your home and family requires.
If you wanted, you could have one indoor air handling unit in your garage, another one for the first floor, and a third one for the upstairs level. If you spend most of the day on the first floor, you can save energy by keeping the other areas at a more energy-efficient temperature.
And since mini-split units don&#;t need any ducts, you won&#;t lose any conditioned air through the ductwork. A typical duct system loses around 20-30% of the conditioned air through gaps and cracks in the ductwork. This is especially significant if you have ducts running in unconditioned areas of the home, such as crawlspaces and attics.
The simple answer is yes, they can provide both heating and cooling. The more complicated answer involved some discussion of the comparisons between heat pumps and more traditional heating methods, such as boilers and gas furnaces.
Like traditional heat pumps, ductless mini-splits connect an indoor air handling unit to an outdoor compressor/condenser. Unlike a heat pump, however, the indoor air handler is directly installed into the room/zone rather than needing the extra ductwork system to transfer the conditioned air into the rooms of your home.
While furnaces generate heat, heat pumps use the existing heat energy that can be found in the air using refrigerant. You may be wondering how a heat pump can provide heat when it&#;s cold out.
A traditional A/C unit works by removing heat from your indoor spaces and transferring the heat outdoors to your condenser unit.
A heat pump essentially reverses this process so it can remove heat from the outdoor environment and transfer that heat indoors. It uses the same principals of an air conditioner, using extremely cold refrigerant to absorb heat from the outdoor environment.
If the refrigerant is even colder than the air outdoors, heat energy can be absorbed since heat naturally flows from a warmer body to a colder body (2nd Law of Thermodynamics). Remarkably, a heat pump can absorb heat even when it is freezing outside (as low as -4 °F).
Still, the colder it gets outside, the harder your heat pump will have to work. Many people with heat pump systems report troubles with heating the home when temperatures drop below freezing (around 32 °F).
For areas that frequently experience freezing temperatures, you may want to consider a backup heating system. In places like Northern California, however, you probably only need a heat pump.

Ductless mini-split systems are great choices for renovations and home additions that don&#;t have any existing ductwork. They are also a great choice for larger homes that only require certain areas of the home to be conditioned at a time. Since each zone has its own thermostat, you can condition the occupied spaces while saving money in the unoccupied ones.
While ductless mini-splits have a lot of advantages, they aren&#;t necessarily right for your home. For instance, if you have a one-floor home with existing ductwork, you are probably better off with a more traditional HVAC unit.
Finding a qualified HVAC contractor to install and service your mini-split system is one of the greatest disadvantages. Luckily, if you live in Northern California, you have the mini-split experts at Service Champions.
Additionally, you may be eligible to receive various tax credits, rebates, and other incentives for heat pump upgrades.

There are many different types of split systems, which can include heat pump systems or air conditioning systems (larger homes might require multiple air conditioners ) installed outside your home, paired with either a gas furnace or a fan coil located inside your home.
Traditionally, the outdoor portion of the unit contains the compressor and condenser, and the indoor portion of the unit contains an evaporator coil and indoor air handling unit that sends the air through the ductwork in your home. These types of HVAC systems are different from HVAC packaged units, where all parts are packaged together in one unit.
How does air conditioning work as a split HVAC system? A split HVAC system is an air conditioning system or heating system that has both indoor and outdoor units that are connected with copper tubing.
Heat pumps run on electricity and draw heat from outside air&#;even cold air&#;and transfer it indoors. The outdoor unit houses a compressor and heat exchanger, and the indoor unit has an air handler and fan that circulate the air inside the home.
Split-system air conditioners are units with the condenser and compressor placed outdoors, and an indoor unit containing the evaporator, furnace, air handler, and filters.
Furnaces are indoor units that burn fuel, like gas or propane, to heat up the air, then distribute it through ductwork in your home.
Fan coils are indoor units that move air over the coil, heat or cool it depending on the weather and season, then distribute it through ductwork in your home.
Split-system HVAC can be ducted or ductless. Ducted split systems use ductwork to circulate the warm air generated from your furnace, fan coil, or heat pump, and the cool air generated by your air conditioner, heat pump, or fan coil. Ductless mini split systems use small air handlers located in specific areas in your home to heat or cool that individual space.
Split HVAC systems have many benefits compared to HVAC packaged units. However, it is important to keep in mind that different types of HVAC systems have benefits for different types of homes, apartments, and condos. While one HVAC system might be best suited for one type of home, it may not be best for another. Our dedicated team of Carrier experts can help you determine the best type of HVAC system for your home and budget.
The efficiency ratings for HVAC split systems can range from the minimum efficiency allowed by the Department of Energy (DOE), to high-efficiency systems with ratings up to 24 SEER2. Split systems that are Energy Star® certified are considered much more energy efficient than those that rated the DOE minimum efficiency standards. Having a more energy-efficient unit can help you to save money on heating and cooling costs, which are traditionally the most expensive parts of your energy bill.
HVAC split systems have two separate components, which allows for more customization in the setup of the system.
Since there are two separate units that comprise the system, split HVAC systems tend to be more expensive to install compared to HVAC packaged units. The installation costs can also increase if the two separate units have to be installed farther apart. The installation costs can vary widely for different types of HVAC split systems, and ductless systems can have more expensive units, but don&#;t require any air ducts to be installed in your home.
If the outdoor compressor is not properly maintained, the unit can be pretty noisy, which can hinder your experience in your yard or on your patio. This can also cause problems if you&#;re a light sleeper and the outdoor unit is placed close to a bedroom.
Since part of the system lives outdoors, there is space needed for the outdoor compressor. This makes it difficult to install these systems if you have a small yard or outdoor space.
