Air Conditioning

Cool down efficiently with a Carrier® air conditioner in Southern Illinois.

With Carrier®, air conditioning is a breeze!
The air conditioner is the reigning king of the cooling season. 110 years after developing the world’s first modern air conditioner, Carrier® continues to lead the pack. Refreshingly energy efficient, quiet and durable, our air conditioning systems are meticulously designed to keep you cool and comfortable, even in the warmest months.

The air conditioner is the baseline of home comfort. A traditional split system consists of an outdoor unit that handles the transfer of heat and the indoor unit that circulates the air in your home. Typically paired with a furnace to provide heat in the winter, an air conditioner can also be installed as an independent system if the building already has a different means of heat such as a boiler.

When looking at cooling equipment, the SEER (Seasonal Energy Efficiency Ratio) value is the primary measure to watch. However, features such as staging and variable-speed compressors can increase energy savings beyond just what a SEER rating lists. We offer a full line of whole-home air conditioning units so you can find the feature set that suits your home.

Not only do we install and replace air conditioning equipment, we also service air conditioners in need of repair. Give us a call and we’ll see to it that your AC is back up and running quickly.

SEER (Seasonal Energy Efficiency Ratio)

Seasonal Energy Efficiency Ratios (SEER) are an industry standard form of comparing an air conditioner’s ability to convert electrical energy into cooling for your home. The higher the SEER, the more efficient the equipment is. Further, SEER is an industry standard, and it can be compared between competitors. Due to new government regulations, the minimum SEER rated condenser allowed to be produced for consumption in residential applications in the USA is 13 SEER. This was revised up from 10 SEER, and has been steadily rising as regulations push for more energy-efficient homes.

Carrier Corporation has taken the lead in air conditioner design to meet the new government requirements, and wiped the slate clean, redesigning their entire air conditioner line for 2006.


Carrier can also claim the leadership position in regards to environmentally friendly refrigerant. With Puron™, Carrier took the industry lead with a non-CFC refrigerant (an ozone depleting compound) in 1993. Carrier is the industry leader in ozone friendly air conditioners. Each and every model of Carrier air conditioner is available as a Puron model, ensuring the greenest possible products!
