Ductless Mini-Split Units with A/C and Heat Pumps Explained

ductless HVAC system

As Middle Tennessee becomes more excited about the options and flexibility of ductless heating and air conditioning systems, research on the topic sometimes leaves prospects with even more questions than they started with. It should come as no surprise that ductless mini-split units have gained popularity in recent years. Did you know they are also able to provide heat as well as air conditioning? Their economical heating and cooling performance abilities are perfect for individual rooms and for smaller applications such as workshops, basements, hobby shops, upstairs living areas, and other spaces. They serve a great niche with individual zone control. This creates a great opportunity for energy savings. Sometimes, finding all the information about their capabilities can be challenging. In this post, the experts here at PJ’s HVAC Repair & Building Maintenance aim to help you in your quest for information on ductless mini-split systems, how they operate, and their proficiency for heating and cooling. If you’d like even more information, the licensed HVAC contractors at PJ’s HVAC Repair & Building Maintenance would love to speak with you!

How ductless mini-split units work

Ductless mini-split units work similarly to standard central air conditioning systems (HVAC) but without the intricacy of duct work. Mini-split units include both an indoor and an outdoor unit.

The indoor unit, also known as the air handler, is where the majority of processes happen. The indoor unit is in charge of delivering conditioned air to the room. Refrigerant is sent to the outdoor unit, pressurized and then pushed back into to the indoor system. In contrast, the functions of a standard HVAC outdoor unit are mostly carried out by the indoor unit in a ductless mini-split system. This single improvement achieved in a mini-split allows it to operate without duct work. This makes it so much more efficient because it’s not wasting energy traveling through mazes of ducting.

Heating and Cooling Capacities of Mini-Split Units

Another great feature is the ability to use one outdoor unit and link it to multiple indoor units. This allows for multiple room use from just one outdoor unit. A maximum number of linked indoor units recommended is four.

Most ductless mini-split units are used for heating and cooling by taking advantage of the heat pump. The compact size and zone flexibility have unique features for businesses and homeowners alike. Owners enjoy their ease of operation, technology connections such as wifi, and the efficient power they pack. Mini-splits are available in multiple capacities: 8,000 BTUs up to about 24,000 BTUs. The smallest units can handle cooling and heating spaces from 250 sq. ft. up to about 1,500 sq. ft. on the larger units.

The heat pump performs two useful functions on mini-split units. During the summer while on the air conditioner setting, the heat pump extracts the heat from the indoor space and sends it outside, in turn blowing cold air into the room. In contrast, during colder temperatures, the heat pump extracts the heat from the outdoors and sends warm air into the room. Bitterly cold, freezing temperatures may require a secondary heat source. A heat pump relies on the ability to draw warm air to function properly.

Energy Efficiency and Expected Savings

Saving money is on everybody’s minds. With an efficient mini-split system, you can expect to save as much as 30% on your heating and cooling expenses. When compared to HVAC comfort levels, mini-split units do as much to provide comfortable indoor temperatures without the loss of air that happens with traditional air ducts. A lack of duct work allows conditioned air and heat to travel basically no distance to reach your indoor space. Furthermore, you’ll have complete zone control. You can control the temperature for a specific room. If at night, you’re only concerned about cooling or heating your bedroom, you can adjust the thermostats to reflect that. It saves wasted air cycling throughout rooms you’re not occupying.
