SEER2 Cooling Efficiency
SEER2 is a seasonal cooling-efficiency rating used for central air conditioners and heat pumps. Higher ratings generally indicate lower seasonal cooling energy use under standardized conditions.

Understand the Ratings
SEER2, EER2, HSPF2, AFUE and Real-World Performance
Efficiency ratings are useful for comparing equipment, but actual results also depend on sizing, ductwork, airflow, controls, weather and building conditions.
EER2 Performance
EER2 reflects cooling efficiency at a specific test condition and can help compare performance during hotter operating conditions.
HSPF2 Heating Efficiency
HSPF2 is used for heat-pump seasonal heating efficiency. Higher values generally indicate more efficient electric heating.
AFUE Furnace Efficiency
AFUE estimates the percentage of fuel converted into usable seasonal heat by a gas or propane furnace.
COP Heat-Pump Performance
Coefficient of Performance compares heat delivered with electrical energy consumed at a specific operating condition.
Variable-Capacity Technology
Inverter and variable-capacity systems can adjust output to match changing loads instead of operating only fully on or fully off.
Airflow Efficiency
Correct airflow is essential for heat transfer, humidity control, comfort and equipment efficiency.
Duct-System Efficiency
Leaky, undersized or poorly insulated ducts can waste conditioned air and reduce delivered system performance.
The Whole System Matters
High-Efficiency Equipment Cannot Overcome Major Airflow or Building Problems
Equipment ratings are only one part of delivered performance. Duct leakage, poor return air, restrictive filters, incorrect refrigerant charge, weak insulation and uncontrolled air leakage can reduce comfort and increase run time.
The best results come from treating the HVAC system and building as connected parts of one comfort system.
Important: Avoid guaranteed savings claims. Actual results vary by equipment, building, weather, rates and customer operation.
Efficiency Depends On
- Equipment efficiency
- Correct sizing
- Airflow
- Duct condition
- Thermostat settings
- Insulation and air sealing
- Maintenance
- Weather and utility rates
Ways to Improve Efficiency
Start with the Improvements That Match the Actual Problem
Professional HVAC Maintenance
Clean coils, correct airflow, verified controls and early problem detection can help preserve system performance.
Proper Equipment Sizing
A load calculation helps avoid oversized or undersized equipment that can cycle poorly and waste energy.
Duct Sealing
Sealing accessible duct leakage can reduce conditioned-air loss into attics, crawlspaces and other unconditioned areas.
Envelope Air Sealing
Reducing uncontrolled building leakage can lower heating and cooling loads and improve comfort.
Insulation Improvements
Appropriate insulation can reduce heat gain and heat loss through the building enclosure.
Smart Thermostat Controls
Scheduling, setbacks, remote access and compatible staging controls can reduce unnecessary operation.
High-Efficiency Replacement
Replacing old or failing equipment with properly selected modern systems may reduce energy use.
Indoor Airflow Balancing
Proper register, return-air and blower setup can improve room comfort and reduce system strain.
Performance Warning Signs
Signs Your HVAC System May Be Wasting Energy
Rising Utility Bills
Increasing energy use without a major weather or occupancy change can indicate equipment, duct or building-envelope problems.
Long Run Times
Extended operation may result from poor capacity, dirty equipment, duct leakage or building-load concerns.
Frequent Cycling
Oversizing, thermostat problems, airflow restrictions or control faults can cause inefficient short cycling.
Uneven Temperatures
Room-to-room differences may point to duct leakage, poor balancing, insulation or equipment issues.
High Indoor Humidity
Incorrect sizing, low airflow, short run cycles or equipment problems can reduce moisture removal.
Weak Airflow
Dirty filters, restrictive ducts, blower problems or blocked coils can reduce delivered performance.
Excessive Noise
Worn components, airflow restrictions or poor installation can increase sound and reduce efficiency.
Older Equipment
Aging equipment may continue operating while using substantially more energy than a properly selected modern system.
Restore Lost Performance
Maintenance and Repair Before Replacement
Dirty coils, airflow restrictions, thermostat problems, refrigerant issues and worn components can reduce performance. Correcting these concerns may restore comfort and reduce run time.
Upgrade When It Makes Sense
High-Efficiency HVAC Replacement Options
Replacement may deserve consideration when equipment is old, unreliable, inefficient, out of warranty or facing major repairs.

Correct Sizing Matters
A Higher Efficiency Rating Does Not Fix Incorrect Equipment Size
Oversized equipment may short cycle, control humidity poorly and create temperature swings. Undersized equipment may run continuously without maintaining comfort.
Load calculations help estimate the capacity the building actually needs before equipment is selected.
