A “seasonal energy efficiency rating,” also called a “SEER,” is a measure of an air conditioning system’s efficiency. By stating the average electricity consumption of an air conditioner during a typical “air conditioning season,” the SEER system allows consumers to more accurately estimate their energy usage than older rating systems allowed. A higher SEER indicates that an air conditioner uses less energy than those with a lower SEER.
For its calculation, a SEER assumes an air conditioner will be in use 1,000 hours per year, which represents eight hours of usage per day for 125 days during the course o/ds significant savings; upgrading from a SEER 9 system, which was previously a common rating, to a SEER 13 system will reduce electricity consumption by a bit over 30 percent. Upgrading from SEER 9 to SEER 16 will reduce energy consumption by nearly 45 percent. While exact savings depends on several variables, most homeowners will see an electricity bill reduction measured in hundreds of dollars per year.
To achieve a higher efficiency, manufacturers use thicker, more efficient metals in their air conditioners. Further, higher rated units generally have multiple compressors and larger coils. This raises the cost of the air conditioning system, so consumers must balance the cost of the unit with their expected energy savings. Most consumer guides recommend purchasing a system with a SEER of at least sixteen.
Additionally, air conditioning units degrade over time. An old unit which had a SEER of nine when it was first installed may currently be operating at a lower SEER. Air conditioning units today tend to retain their rating longer, but it is worth noting that the more expensive materials used in more efficient systems can be expected to help maintain the unit’s rating longer than less efficient systems.
And for those who seek to reduce their impact on the environment, a system with a higher efficiency rating helps reduce energy-related pollution. Systems with a higher SEER will also last longer and reduce the amount of material that ends up in a landfill.
At one time, those looking to purchase a new air conditioner had no means to calculate the energy cost of their purchase; manufacturers had no incentive to focus on efficiency over cost. The SEER system has provided consumers with a valuable tool to calculate the true cost of their new air conditioner.
If you want low electric bills with the best efficiency, then there are only two factors, which can help you first is the best installation because a lot of time because of poor installation people face problem for all time and second is its regular scheduled maintenance which may cut your cost by 30 to 40% or may be more.
