My air conditioning unit is really old, probably about 14 years old, it has a Seasonal Energy Efficiency Rating (SEER) of 10. When should I replace it? and what SEER rating should I look for?
Most central air conditioning units have a lifespan of around 20 years. Your air conditioning unit is well past its mid-life range. Even if your HVAC system is only 10 years old, you may save 30-50 percent of your cooling energy costs by replacing it with a new, more efficient model.
When shopping for a new central air unit, look for a SEER of at least 18. A variable speed air handler for new ventilation systems is best, but two-speed is still much more efficient than single speed. Bryant Evolution® Series Air Conditioners are available in variable-speed as well as 1- and 2-stage units, these powerful air conditioners can operate as quietly as a vacuum with up to 21 SEER efficiency ratings. All Byant Evolution® Series Air Conditioners can be controlled from almost anywhere with the Evolution® Connex® control. Enjoy consistent comfort, even on extreme days. Ensure the unit has a thermal expansion valve, which maintains efficiency even with less than optimal refrigerant charge. If you live in a humid climate, make sure the sensible heat ratio is .7 or higher (this means the unit has good performance at high humidity). Of course, also make sure the unit is ENERGY STAR® rated.
In addition to purchasing an energy an efficient unit, professional installation is important to getting the performance you expect. Our installer will perform an industry-approved sizing calculation. Our Installers will check your air ducts for leakage and seal them to prevent leakage, which limits your air conditioner’s airflow. Once the new AC unit is installed, our installer verifies the airflow across the Air conditioner coil and the air flow in each room.
