How AC Works + AC Basics

Energy Efficiency is Important

What are the different energy efficient ratings?

SEER- Seasonal Energy Efficiency Rating

  • Measure of efficiency by which the cooling process is rated
  • Represents the expected overall performance for a typical year's weather
  • Higher SEER = Greater Efficiency = Greater Savings
  • Applies to Conventional (Air Source) systems
  • SEER ratings range from 13 to 23
  • The SEER rating is shown on the EnergyGuide sticker which should be attached to the outside of a conventional system

EER- Energy Efficiency Ratio

  • Measure of Efficiency of a Cooling System based on specific temperature levels.
  • Generally calculated using a 95° outside temp.
  • Higher EER = Greater Efficiency = Greater Savings
  • Applies to Geothermal (Ground Source) systems

Conventional Air Conditioning System

  • Select a SEER rating that works within your budget
  • Any increase in SEER rating from your current system WILL save you money

How it Works:

A conventional system uses a system of:

  • Ducts, Supply & Return Vents and Thermostats
  • Indoor Air Handler
  • Outdoor Compressor

Air Conditioning Unit:

The system uses outdoor air to remove heat & humidity from within the house in hot weather OR add heat to the house in cold weather.

Heat Pumps:

A Heat Pump works like an air conditioner, but it also has a heating mode.

Liquid refrigerant is used to carry the heat.

In hot weather, the heat pump removes hot air from inside the building and sends it outside.

In heating mode, the refrigerant flow is reversed in order to get heat from the outside air to bring into the building.

The Split System:

Inside and Outside Components

  • The outdoor unit contains a compressor which controls the pressure applied to the refrigerant
  • Also contains a condensor coil that converts the refrigerant from a gas to a liquid, and sends heat carried by the refrigerant outside.
  • The Indoor Unit contains the Evaporator Coil
  • This part cools and dehumidifies the air
  • It converts the liquid refrigerant into a gas (or vice-versa)
  • A blower motor then moves air over the coil to either heat or cool

ABOUT GEOTHERMAL COOLING

How Geothermal Works:

When the outside air temperature is 95 degrees, just a few feet below the ground, the temperature is about 72 degrees. Air conditioning systems cool the air before blowing it through the building. Starting with a temperature of 72 degrees instead of 95 degrees makes a lot of sense. This is geothermal cooling in a nutshell.

Using the Earth

  • Air temperature goes up and down throughout the year
  • But underground temperatures remain relatively constant
  • Air conditioners work by exchanging hot air for cold
  • Conventional systems use the outside air which is hotter than the ground
  • Geothermal sytems use a buried loop of piping containing fluid that circulates through the pipes
  • In winter, the fluid takes in heat from the earth, then transports it to the indoor unit to be sent through the building
  • In summer, the process reverses
  • Takes in heat from the building
  • Sends it out to the surrounding ground


Geothermal Systems

  • Typically no outdoor unit
  • Increases longevity of equipment as it is not exposed to the elements
  • Lasts 2 to 3 times longer than conventional systems
  • Reduces energy costs ranging from 30-60%
  • Low maintenance


The best type of geothermal loop system to use depends on the existing property, available ground space, and existing structures and driveways, parking areas, etc. Each type works well, and regardless of the type, geothermal cooling, heating, and pool heating is extremely efficient. For saving energy costs, it can’t be beat.
