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.

Great service and great people to deal with, from sales to installer. I highly recommend this company.

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!
