How Much Money Can a New Air Conditioner Save You?

Our SEER2 (Seasonal Energy Efficiency Ratio 2) energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit’s SEER value and compare it to a newer, more efficient SEER2 unit. You can even customize it to better match your home’s system for a more accurate calculation.

Air Conditioning Basics

The four main components to your air conditioner are:

Condenser: This is the outdoor unit where the refrigerant from the compressor is condensed into liquid. When the gas enters the compressor it is extremely hot but then lowers in temperature and converts back to a liquid form.

Compressor: This is located inside of the condenser and circulates the pressurized refrigerant, concentrating the heat and converting the gas from low to high pressure.

Evaporator: The indoor part of the system that absorbs the heat from your home.

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

These components are connected by a copper tube that handles the refrigerant and creates a closed loop. Heat is collected in the evaporator then sent to the condenser where heat is removed and circulated back into your home in the form of cool air.

AC Facts

An Air Conditioner Does Not Create Cool Air.
What happens in the process is the removal of heat from the air. The warm air goes over the coils in your unit, converting from liquid to gas and back again. In the process, the refrigerant removes the heat and transfers it outside so the air produced in your home is cool.

Your AC Will Remove Humidity.
Lower humidity improves the overall level of comfort by making you feel cooler even if the temperature remains the same.

Your Air Filter Needs to be Checked and Replaced Every 2-6 Months (depending on manufacturer's recommendations).
A dirty filter restricts air flow, thus reducing efficiency and creating the potential for a costly repair due to stress placed on the unit.

Maintenance, Maintenance, Maintenance.
Your HVAC system requires an annual check-up to ensure it continues performing at max capacity and peak efficiency. Regular preventative maintenance will bring your system a longer life and fewer breakdowns.

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.
