White air conditioner in modern room

Are you looking for a way to improve the comfort and efficiency of your home or business? Do you have rooms that are too hot or too cold, or spaces that are not connected to your existing HVAC system? If so, you might want to consider a ductless HVAC system as a flexible and efficient solution for any space. With its ability to provide both heating and cooling, along with easy installation and customizable options, ductless heat pumps may be the right choice for your home.

A ductless HVAC system, also known as a ductless mini split system, is a type of heating and cooling system that does not require traditional ductwork to distribute air. Instead, it consists of two main components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor and the condenser, while the indoor unit contains the evaporator and the fan. The two units are connected by a refrigerant line that runs through a small hole in the wall. The indoor unit, which can be mounted on the wall, ceiling, or floor, is controlled by a remote and allows for personalized temperature control in each room. Ductless heating and air conditioning systems are a flexible and efficient solution for any space.

Benefits of

There are many benefits of choosing a ductless HVAC system for your home or business, such as:


You can install a ductless HVAC system in any room or space that needs heating or cooling, such as room additions, basements, attics, garages, sunrooms, offices, and more. This flexibility allows you to customize your comfort by adding multiple indoor units around your home, each with its own thermostat. You can also choose from different types and sizes of indoor units to suit your needs and preferences. For example, you can opt for a wall-mounted unit, a ceiling cassette, a floor-standing unit, or a concealed ducted unit. You can also have multiple indoor units connected to one outdoor unit, creating a multi-zone system that allows you to control the temperature in each room individually.


A ductless HVAC system can help you save energy and money on your utility bills. Unlike a central heating and cooling system that relies on ductwork to distribute air, a ductless system delivers air directly to the room where it is needed, reducing energy losses and improving performance. A ductless system also uses less energy than a window room air conditioner or a baseboard heating system, as it operates on a variable speed compressor that adjusts to the demand, rather than cycling on and off. Additionally, a ductless system can qualify for a federal tax credit and a local utility rebate, depending on the model and the installation. This is because ductless systems avoid the energy losses associated with ductwork of central forced air systems, making them a more efficient solution for any space.


A ductless HVAC system can improve the air quality and comfort of your home or business. A ductless system has a built-in filter that can remove dust, pollen, allergens, and other contaminants from the indoor air, creating a healthier and cleaner environment. A ductless system also has a humidity control feature that can prevent mold and mildew growth, as well as a noise reduction feature that can make it quieter than a conventional system. Moreover, a ductless system can provide both heating and cooling functions, depending on the season and the weather, ensuring that you always have the optimal temperature in your space.

How Do You Choose and Install a Ductless HVAC System?

If you are interested in installing a ductless HVAC system in your home or business, there are some factors that you need to consider, such as the cooling capacity, its efficiency, and the installation and maintenance requirements.

Cooling capacity

The cooling capacity of a ductless system is measured in British thermal units (BTUs) per hour, and it indicates how much heat the system can remove from the space. The cooling capacity that you need depends on the size, layout, insulation, and orientation of your space, as well as the number of people and appliances in it. Generally, the larger and more crowded the space, the higher the cooling capacity required. You can use an online or consult a professional to estimate the cooling capacity that you need for your space.

The of a ductless system is measured by the seasonal ratio (SEER) and the energy efficiency ratio (EER), which indicate how much cooling the system can provide per unit of electricity consumed. The higher the SEER and EER ratings, the more efficient the system is. You should look for a ductless system that has a SEER rating of at least 15 and an EER rating of at least 12, as these are the minimum standards for energy efficiency set by the Energy Star program. You can also look for a ductless system that has an inverter technology, which can further enhance the efficiency and performance of the system by modulating the speed of the compressor according to the load.


The installation of a ductless system is relatively easy and fast, compared to a conventional system that requires extensive ductwork. However, it still requires some skill and expertise, as it involves drilling a small hole in the wall, running the refrigerant line, connecting the electrical wiring, and mounting the indoor and outdoor units. 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. Therefore, it is recommended that you hire a licensed and experienced contractor to install your ductless system, as they can ensure that the system is installed correctly and safely, and that it meets the local codes and regulations. You should also ask for a warranty and a service contract from your contractor, as these can protect you from any defects or malfunctions that may occur in the future.

How to Maintain a Ductless HVAC System

Once you have installed a ductless HVAC system in your home or business, you need to maintain it regularly to keep it in good condition and extend its lifespan. Some of the maintenance tasks that you need to perform are:

Cleaning the filters

You should clean the filters of your ductless system at least once a month, or more often if you have pets or allergies. Regular maintenance, including cleaning the filters, is essential for keeping your ductless HVAC system running efficiently. To clean the filters, you need to remove them from the indoor unit, rinse them with water, and let them dry completely before putting them back. You can also use a vacuum cleaner or a soft brush to remove any dust or debris from the filters. Cleaning the filters can improve the air quality and the efficiency of your system, as well as prevent any clogs or damages.

Cleaning the coils

You should clean the coils of your ductless system at least once a year, or more often if you live in a dusty or humid area. To clean the coils, you need to turn off the power to the system, remove the cover from the outdoor unit, and spray the coils with a coil cleaner or a mild detergent. You can also use a soft brush or a cloth to wipe off any dirt or grime from the coils. Cleaning the coils can improve the heat transfer and the performance of your system, as well as prevent any corrosion or leaks.

Checking the refrigerant

You should check the refrigerant level of your ductless system at least once a year, or more often if you notice any signs of low refrigerant, such as reduced cooling, ice formation, or hissing noises. To check the refrigerant level, you need to use a gauge or a meter that can measure the pressure and the temperature of the refrigerant. You can also consult the manual or the label of your system to find the optimal refrigerant level for your model. If the refrigerant level is too low or too high, you need to call a professional to adjust it, as this can affect the efficiency and the safety of your system.
