SEER

The Seasonal Energy Efficiency Ratio (SEER) indicates the cooling efficiency of air conditioner and heat pump systems. The higher the SEER number, the greater the efficiency and the greater the energy savings. All new products have a 13.0 SEER rating or better. At Carrier, we offer air conditioner and heat pump systems that can achieve SEER ratings of over 20.

EER

Energy Efficiency Rating (EER) measures cooling efficiency and is calculated by dividing a product’s BTU output by the watts of power it uses. Generally, higher is better. (Noticing a trend here?)

HVAC

Term used for Heating Ventilation and Air Conditioning.

R-22 REFRIGERANT

R-22 is a single-component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air conditioning and refrigeration applications in a variety of markets. Production of R-22 will cease in 2015 per the Montreal Protocol. Also commonly known as Freon.

AIR CONDITIONER MAINTENANCE

• Change your air filters regularly.
• Be sure to avoid blocking floor, wall or ceiling vents.
• Make sure your outside condensing unit isn’t covered or clogged with leaves or debris.
• Check to make sure the drainage system isn’t clogged.
• Don’t run your system in cooling mode when outdoor temperatures are lower than 55° F or 13° C.
• Have a Cooling Tech expert clean your indoor coil regularly.
• Check for water at the base of your outdoor unit. Water likely means the support base has shifted since installation and is no longer level.
• Consider sealing or insulating your ducts.
