How can I find the savings of higher SEER equipment compared to lower SEER equipment?
You’ll need to talk with a local contractor to verify what size cooling equipment you now have and what you actually need, then determine the normal cooling load hours for your area, and find your electric rate cost. When cooling, heat pump performance is measured in seasonal energy efficiency ratio (SEER). When heating, it is measured in coefficient of performance (COP) or heating seasonal performance factor (HSPF). In all measurements, the higher the rating the more efficient the system. The formula is as follows: Capacity (Btuh) Cooling Load Hours ————— X —————— X Electric Rate = Annual Operating Cost SEER 1000 For example, if a home requires a unit with a capacity of 36,000 British thermal units per hour (Btuh), is located where the cooling load is 1500 hours and the electric rate is 8 cents per kilowatt hour, here is the calculation for a system with a SEER of 10: 36,000 x 1500 —— X —- X .
