1. What is SEER?

The efficiency of heat pumps and air conditioners is expressed by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER number, the more cooling you will get for your money. The SEER will be listed on the yellow and black Energy Guide located on the unit.

The SEER is defined as the total cooling output in British thermal units or BTU provided by the unit during its normal annual usage period divided by its total energy input (in watt-hours during the same period).

2. Why is replacing old equipment important?

A central air conditioning system is designed to last 12 - 18 years, so in some cases savings and reliability are limited due to equipment age. Your air conditioning contractor can help you decide when it is time to replace your old equipment with high efficiency equipment before your system breaks down and leaves you in the heat.

3. Why is duct testing important?

The ducts that are part of central heating and cooling systems offer one of the best opportunities to increase your energy efficiency, increase your comfort, and manage your energy bills. Studies indicate that 28% - 35% of the heated or cooled air is lost-along with the money spent to heat or cool that air-through leaky ducts. Properly sized, installed, and sealed duct-work will make your heating and cooling systems significantly more efficient.

4. Why is refrigerant change and airflow important?

A system refrigerant check-up is a recommended service that should be performed when the equipment is first installed and during annual system check-ups. A refrigerant charge should be conducted if the system check indicates that one is needed.

Once the system has been properly charged with refrigerant and has good airflow across the indoor coil, and assuming there is no damage to the duct system, only basic service such as changing filters and cleaning the outdoor unit annually should be needed to maintain the system operation at peak performance levels.
