Ductless air conditioners use an indoor and outdoor unit connected by refrigerant lines, providing efficient, flexible, and zone-specific cooling without ductwork.
Ductless air conditioners, also known as mini-split systems, have become a popular choice for homeowners and businesses seeking efficient, flexible, and cost-effective cooling solutions. These systems offer several advantages over traditional central air conditioning systems, especially in homes without existing ductwork. But how exactly do ductless air conditioners work?
My a/c was not working correctly and I knew it needed to be serviced. The person came and cleaned what needed to be cleaned and he did what he could for the output. He was very professional and nice. We will definitely call them for our future needs.

We have used Thomas Hoffman Air Conditioning and Heating for AC issues for the last two years. We have been so happy with the service we have received both times. This year, we just needed a little maintenance as our unit wasn’t working to its full potential. I called first thing in the morning and was able to get a same day appointment! Nick was so personable and knowledgeable, and he got us back up and running and no time. Thank you again for saving us from the summer heat!! We are so grateful for the amazing customer service you guys provide!!!
Response from the owner:Thank you so much, Teri, for your kind words and for trusting us with your AC needs over the past two years; we're glad Nick could help get your unit back to its best, and we truly appreciate your gratitude for our service!

I txt Thomas Hoffman air-conditioning and heating Sunday early evening about 6:30 and just left A detailed message of what was going on with my AC I received an automated reply, saying they would contact me soon. I heard from them the next Morning at 11 AM to confirm what was going on with my unit and said they would have a Tech out today still but would be the last call between 6 and 8pm. I expected to get an appointment 2 to 3 days later. We’re in the middle of about an 8 to 10 day Heat wave of Mid to upper 90s. So imagine my surprise when I received a call from Zachary at 3:20 telling me he was in Saint Charles and was on his way to my house to look at the unit. When I explained what was wrong on the phone, he was pretty confident. He knew what it was once he got here, pulled off the cover and sure enough it was the capacitor. Pull the old one off and install the new one turned it back on and boom I have cold air blowing. I would highly recommend Thomas Hoffman, AC and heating and if you can request a certain Tech Zachary is your guy he is great super Frndly got the job done quickly and even interacted with my dogs Who are super friendly
Response from the owner:Thank you, Vicki, for sharing your experience with us! We're glad to hear that Zachary was able to resolve your AC issue quickly and that he made a positive impression on both you and your dogs. We truly appreciate your recommendation and look forward to assisting you again!
We can’t say how happy we are with the quick and efficient service! We came home Friday evening after work on a 95 degree day (with a week of 90 degree weather ahead) and our A/C was totally out. We called this small business owner around 6pm and he was here by 7:25. He replaced our wires, had cool air running, gave us some helpful tips for the future, and was already out the door by 7:50. He was very polite, friendly, straightforward, and saved our evening/weekend!
Response from the owner:Thank you, Morgan, for your wonderful feedback! We're glad our team could provide quick and efficient service to keep you comfortable during the heat. Your satisfaction means a lot to us!

The Basics of Ductless Air Conditioners
A ductless air conditioner consists of two main components: an indoor unit and an outdoor unit. These units are connected by a conduit that houses the power cable, refrigerant tubing, suction tubing, and a condensate drain. Here’s a breakdown of each component:
Indoor Unit
The indoor unit, also known as the air handler, is usually mounted high on a wall or ceiling. It contains an evaporator coil, a fan, and an air filter. The indoor unit blows the cooled air directly into the room. It operates quietly and can be controlled via a remote or a wall-mounted thermostat.
Outdoor Unit
The outdoor unit contains the compressor, condenser coil, and expansion valve and is typically placed outside on a concrete pad. The compressor is the heart of the system, responsible for circulating refrigerant between the indoor and outdoor units. The outdoor unit dissipates the heat absorbed from inside the building, releasing it into the outside air.
How Ductless Air Conditioners Operate
Refrigerant Cycle
Ductless air conditioners operate using a refrigeration cycle, similar to traditional air conditioning systems. Here’s a step-by-step look at how they work:
Refrigerant Absorption: The indoor unit absorbs the warm air from the room. The refrigerant in the evaporator coil absorbs the heat from this air, causing the refrigerant to evaporate into a gas.
Compression: The refrigerant gas travels through the conduit to the outdoor unit. The compressor compresses the gas, raising its temperature and pressure.
Heat Release: The high-pressure refrigerant gas moves to the condenser coil in the outdoor unit. Here, it releases the absorbed heat to the outside air, causing the refrigerant to condense back into a liquid.
Expansion: The high-pressure liquid refrigerant then passes through the expansion valve, reducing its pressure and temperature.
Cooling Cycle: The cooled refrigerant returns to the indoor unit, ready to absorb more heat from the room. This cycle repeats, maintaining a cool and comfortable indoor environment.
Zoning Capabilities
One of the standout features of ductless air conditioners is their zoning capability. Each indoor unit operates independently, allowing for customized temperature control in different rooms or zones. This flexibility enhances comfort and improves energy efficiency, as you can cool only the occupied areas rather than the entire building.
Advantages of Ductless Air Conditioners
Energy Efficiency
Ductless systems are known for their high energy efficiency. Since there are no ducts, there is no energy loss associated with duct leakage, which can account for up to 30% of energy consumption in traditional systems. Additionally, the ability to cool specific zones reduces unnecessary energy use.
Easy Installation
Installing a ductless system is less invasive than installing a central air conditioning system. The absence of ductwork means less construction work, making it a great option for older homes or buildings without existing ducts.
Improved Indoor Air Quality
Ductless air conditioners often come with advanced filtration systems that reduce dust, allergens, and other pollutants. This leads to better indoor air quality, which is especially beneficial for those with allergies or respiratory issues.
Quiet Operation
Both the indoor and outdoor units of ductless systems are designed for quiet operation. The indoor unit often operates at a whisper-quiet level, making it ideal for bedrooms, living rooms, and other quiet spaces.
Versatility
Ductless systems are versatile and can be used in various applications, from single-room additions to entire homes and commercial spaces such as offices and retail stores.
