Ductless Cooling For Your Home

Since 1999, our team of experts at Argus Air Systems has been providing quality and reliable services to ensure the comfort of our customers. With ample experience on ductless cooling systems, we can proudly say that we are one of the leading HVAC companies in Fairfield County.

What is Ductless Cooling?

Air conditioners work by drawing heat energy out of the house, transferring it outdoors and subsequently replacing the air inside your home with cooler air. The ductwork is the part of the system that allows cool air to travel inside your home.

In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from gas to liquid. This liquid is then forced through the indoor evaporator or cooling compartment. An indoor unit fan circulates the inside air to pass across the evaporator fins. Thereafter, the evaporator’s metal fins exchange the thermal energy with the air around it. There, the refrigerant turns from liquid into vapor, removing any heat from the surrounding air. As the heat is removed from the air, the air is cooled and blown back into the house.

From that point, the condenser or outdoor unit then turns the refrigerant vapor back into a liquid, removing any heat. By the time the fluid leaves the evaporator again, it is a cool, low-pressure gas, eventually returning to the condenser to begin its trip all over again. This process repeats itself until your home reaches the desired cooling temperature, as programmed and sensed by your thermostat setting.

Many air conditioning systems can make your home cooler, but few can do the job as efficiently and professionally as Argus Air Systems Inc. can.

Choosing a new cooling system can be confusing. Explained below are some important HVAC terms that may help you better understand our process.


Air Conditioners have a “SEER” (Seasonal Energy Efficiency Rating) or “EER” (Energy Efficiency Ration) – the higher the number, the more efficient the system. Our energy-efficient models start at a 13 SEER rating and our best achieves 20 SEER.

EER – is the cost of operation during a steady state period of operation.

80° dry bulb, 67° wet bulb = indoor air, 95° dry bulb, outdoor air




SEER – is the average cost of operation during the entire cooling season.

80° dry bulb, 67° wet bulb = indoor air, 82° dry bulb, outdoor air





Though SEER ratings are established in a laboratory, the real conditions determine how your equipment will perform. Many things affect how cooling equipment meets the anticipated performance level:

Airflow – without proper airflow, the desired temperature change across the evaporator will not occur, hence not cooling your home properly.

Charge – improper refrigerant charge can greatly affect the performance of your air conditioner.

Tight Ducts – duct leakage can greatly reduce the performance of your air conditioner. Make sure your ducts don’t leak.

Size – equipment that is too large will hurt the performance of the unit. If it is sized too small, the equipment will not satisfy your cooling needs.

Maintenance Tips

Keep the outside clean

One of the easiest things you can do to keep your system in shape is to make sure that it is free from dust and debris. If you allow dust, dirt, and other particles to collect on the unit, they can easily find their way into the operating pieces and ultimately lead to major issues.

Check for ice or snow

When used for heating, ductless air conditioners can collect ice and snow, which can inhibit their ability to run efficiently. Regularly check the outside of your unit for accumulation and, if you spot any, gently remove it from the area. During the winter, you are likely running your unit frequently, and you will want to make sure that it is protected. Failure to clean this part of the unit covered in ice can quickly lead to expensive issues.

Give it some space

While ductless air conditioners require less space than your average air conditioning system, they do work best if you give them plenty of unobstructed room to operate. To run smoothly, the unit needs to have ample wall space to work. Make sure that you do not have any large furniture or art surrounding it, as these items can encourage the accumulation of dust and can hinder the efficiency of the system.

You want to make sure to give the machinery at least four feet of surrounding space in every direction, besides the walls themselves. Avoid placing bookcases or pictures on the wall near the ductless air conditioning unit. Clearing the space will prevent issues later and ensure that your machine is working correctly.
