Air Conditioning

Air Conditioning Basics

The four main components to your air conditioner are:

Condenser
The condenser is the outside metal unit and where the gas from the compressor is condensed into a liquid. The gas entering the condenser is very hot. The temperature is then lowered, so the gas can convert back to a liquid.

Compressor
The compressor is inside the condenser. It circulates the pressurized refrigerant, to concentrate the heat, and changes the low pressure gas to high pressure gas.

Evaporator
The evaporator is the part of the system inside the home. In simple language, it absorbs the heat from your home.

Expansion Valve
The expansion valve controls the amount of refrigerant in your system.

All of these pieces are connected by a copper tube that handles refrigerant, creating a closed loop. Heat is collected in the evaporator, sent outside to the condenser. The heat is removed, and the cool air is recirculated back into your home.

AC in the Know: Basic facts about air conditioning operation

An air conditioner doesn’t create cool air
What happens in the air conditioning process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The refrigerant runs through the lines and coils in your unit and goes from liquid to gas and back again, absorbing the heat and transfering it elsewhere so that when the air comes out the other side, it is cool.

Your AC will remove humidity
Lower humidity helps the overall comfort level in your home by making you feel cooler, even if the temperature is the same.

Your air filter needs to be checked and replaced every three to six months (depending on the manufacturer’s recommendations).
A dirty air filter restricts your air flow, which reduces efficiency, costing you money, and over time can put stress on your unit and could cause a costly repair and/or premature (catastrophic) failure.

Maintenance, maintenance, maintenance
Your HVAC system needs regular checkups to keep it running in tip-top shape. Like your car needs regular maintenance (oil/fluid changes, tire rotation, etc), so too does your HVAC system. Having regular annual preventative maintenance saves you money and will bring your system longer life and fewer breakdowns over all.

SEER
The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency. [Trane]
