How Does a Ductless Heat Pump Work?
Posted On: November 28, 2023
A ductless heat pump, also known as a mini-split system, is a type of heating, ventilation, and air conditioning (HVAC) system that provides both heating and cooling to a building without the need for traditional ductwork. Here's a basic overview of how a ductless heat pump works:
-
Components:
- Outdoor Unit (Condenser): This unit is installed outside the building and contains the compressor, condenser coil, and a fan. It is responsible for releasing or absorbing heat, depending on whether the system is in cooling or heating mode.
- Indoor Units (Evaporators): These units are installed inside the building and are responsible for distributing conditioned air. Each indoor unit is connected to the outdoor unit by refrigerant lines.
-
Refrigeration Cycle:
-
Cooling Mode:
- The refrigerant in the system absorbs heat from the indoor air through the indoor unit's evaporator coil.
- The absorbed heat is then transported to the outdoor unit.
- In the outdoor unit, the compressor increases the pressure and temperature of the refrigerant.
- The refrigerant releases the absorbed heat to the outdoor air through the condenser coil and the fan.
-
Heating Mode:
- The refrigerant absorbs heat from the outdoor air in cold weather.
- The compressor increases the temperature of the refrigerant.
- The heated refrigerant is then circulated to the indoor units.
- In the indoor units, the refrigerant releases heat to the indoor air through the evaporator coil.
-
-
Distribution of Conditioned Air:
- Each indoor unit is equipped with a fan that distributes the conditioned air within the specific zone it serves.
- Ductless systems can have multiple indoor units connected to a single outdoor unit, allowing for zoned heating and cooling. This means different rooms or areas can be conditioned independently.
-
Zoning and Individual Control:
- One of the advantages of ductless heat pumps is the ability to create multiple zones with individual temperature controls. Each indoor unit can be controlled independently, allowing for personalized comfort and energy efficiency.
-
Energy Efficiency:
- Ductless systems are often more energy-efficient than traditional HVAC systems because they don't experience the energy losses associated with ductwork. They can also be more efficient in mild climates.
In summary, a ductless heat pump works by transferring heat between indoor and outdoor units through a refrigeration cycle, providing both heating and cooling. The absence of ducts and the ability to create independent zones make these systems versatile and energy-efficient.

We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.

Great experience getting an old furnace replaced.
Sales Guy (Dave) was great - honest, responsive, and friendly.
The work itself was done quickly and we are very happy with the outcome, thank you! We recommend TwinTech!

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.

Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!

One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they werent the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.

Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!
