Your air conditioning system represents the largest percentage of summer electric bills. If it is over ten years old, it could be costing you twice what it should. Due to advances in technology and updated government regulations, today’s cooling units are far more efficient than decade-old equipment.
Like other HVAC equipment, central air conditioners are rated for efficiency using Seasonal Energy Efficiency Rating (SEER). Again, think of SEER like your vehicle’s gas mileage: the higher the SEER rating, the more you save. Twenty years ago, the average air conditioner had a SEER of around 6. Today’s systems range from 13 to 24!
