- Two-stage and Modulating systems can provide more even heat distribution without temperature fluctuations throughout your home
- A variable speed direct current motor (ECM) allows the furnace to operate on a lower fan speed 90% of the time, leading to quitter operation.This can also help reduce your annual electricity bill by approximately $200 to $300/year.

Things to consider when it is time to replace your air conditioner
- The average life expectancy of central air conditioner is from12 to 15 years.
- A 13 SEER unit will deliver approximately 23% energy saving compared to a 10 SEER model and approximately 8% energy savings compared to a 12 SEER models.
- A 12 years old air conditioner has an approximate SEER ratings 7.0 and 8.0, compared with some new models that are twice as efficient. The more efficient unit could pay for itself through decreased utility bills and offer improved reliability and warranty protection.
- If your furnace is the same age as your central air conditioner, consider replacing it at the same time.
