An air conditioner can change the temperature, humidity or general quality of the air. More specifically, an air conditioner makes your home cooler, by drawing heat energy out of the house and transferring that heat to the outdoors, then replacing the air inside your home with cooler air.
- How It Works
The air conditioner in a central heating and cooling system provides cool air through ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat. In a split system, the compressor condenses and circulates the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment. The indoor unit’s fan circulates the inside air to pass across the evaporator fins. 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 continues again and again until your home reaches the cooling temperature you want, 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 can. Installing a new system or replacing the old noisy clunker in the backyard? Give us a call we would be happy to hear from you.
Choosing a new cooling system can be confusing and frustrating some terms you may hear or read about are explained below
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 20SEER.
- EER vs. SEER
EER – is the cost of operation during 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
Remember that SEER ratings are established in a laboratory, but the real conditions determine how your equipment will perform. Many things affect how cooling equipment meets anticipated performance level:
- Airflow – without proper airflow, the desired temperature change across the evaporator will not occur, therefore not cooling your home properly.
- Charge – improper refrigerant charge can greatly affect the performance of your air conditioner.
- Tight Ducts – Duct leakage can also greatly reduce the performance of your air conditioner. Make sure yours don’t leak.
- Size – equipment that is sized too big will hurt performance of the unit. If it is sized too small, the equipment will not satisfy your cooling needs.
This ensures that you have a working and clean air filter that is suitable for your exiting system. Although you are able to change your filter yourself (and you should!), we might point out a better filter or filtration system that you should be using.
To ensure your thermostat is working properly, our technician will calibrate the thermostat and make sure it is installed properly and located away from all heat sources, including light bulbs and heat-producing appliances.
