A SEER rating measures the cooling efficiency of an air conditioner, and the higher the rating, the more efficient the unit. Considering buying an air conditioner, you will want to know what SEER ratings mean and how they affect your purchase. Here are some frequently asked questions about SEER ratings.
What is a SEER rating?
The SEER rating measures how efficient an air conditioner or heat pump is, and SEER stands for Seasonal Energy Efficiency Ratio. The ratio is derived by dividing the system’s cooling output in BTUs by the total electrical energy input in watt hours.
For example, if an air conditioner has a SEER rating of 10, it means that for every 1000 watts of energy it uses, it produces 10,000 BTUs of cooling. An air conditioner must have a SEER rating of 14 or higher to be eligible for ENERGY STAR® certification. Be sure to ask your contractor about the SEER rating of any unit they install for you. A higher efficiency unit will cost more upfront but will save you money in the long run through lower utility bills.
How much more efficient is a 20 SEER unit compared to a 14 SEER model?
A home’s central air conditioner is typically one of the most expensive appliances to purchase and operate. The seer rating often measures the conditioner’s efficiency. The higher the SEER rating, the more efficient the unit and the lower your energy costs. For central air conditioners, the minimum SEER rating that you can purchase is 14. However, 20 SEER units are available and are significantly more efficient. In fact, a 20 SEER unit is almost 50% more efficient than a 14 SEER unit. It will use less energy to cool your home, saving you money on your energy bills. If you are looking for ways to reduce your energy costs, upgrading to a 20 SEER air conditioner is a great place to start.
How do you convert SEER to EER?
SEER measures how much cooling capacity an air conditioner or heat pump consumes for each unit of energy. The EER, or Energy Efficiency Ratio, is a similar measure but is usually only used for units operating at full capacity. To convert SEER to EER, divide the SEER rating by 3.4. For example, if an air conditioner has a SEER rating of 18, its EER would be 18/3.4, or 5.29. When comparing the efficiency of different units, it is important to compare apples to apples by looking at the SEER or EER ratings. Otherwise, you could be misled by incorrect information.
Does a 14 SEER qualify for a tax credit?
Congress offers a tax credit to people who install energy-efficient products in their homes as an incentive to help save energy and money. The credit is only available for certain types and sizes of energy-efficient products, so it is important to ensure that any products you purchase qualify before buying them. A 14 SEER air conditioner is one type of product that may be eligible for the tax credit. The credit is usually only available for new installations, so if you consider buying a 14 SEER unit to replace an old one, you may not be eligible. Check with your tax advisor or the IRS website to see if a 14 SEER unit qualifies for the tax credit before making your purchase.
So, what have we learned? SEER ratings are important regarding air conditioners, but they should not be the only factor you consider. Make sure to look at other factors such as size and price before making your purchase.
