Air Conditioning Basics

Understanding the key components of your air conditioning system can help you appreciate the complexity and importance of regular maintenance.


Located outside your home, this component condenses gas into a liquid, releasing heat in the process.


Situated within the condenser, it pressurizes refrigerant to concentrate heat, transitioning it from low to high pressure.


Found inside the home, it absorbs heat, cooling the air.

Expansion Valve

This regulates the refrigerant flow, ensuring efficient operation.

Together, these components work in harmony to remove heat from your home, circulating cool, comfortable air.

The Importance of Air Conditioner Maintenance

Cooling Process

Air conditioners don’t produce cool air; they remove heat from the air, utilizing refrigerant to transfer heat outside, thus cooling the air indoors.

Humidity Reduction

By lowering humidity, your AC enhances comfort even at the same temperature.

Air Filter Maintenance

Replacing your air filter every three to six months ensures efficiency and prolongs your system’s life.

Regular Maintenance

Annual checkups prevent breakdowns, extending the lifespan of your unit.

Cooling Efficiency with SEER

The Seasonal Energy Efficiency Ratio (SEER) is a measure of cooling efficiency for air conditioners and heat pumps. A higher SEER rating signifies greater energy efficiency, offering potential savings on energy bills while reducing environmental impact.
