Many home and business owners are choosing high-efficiency cooling systems. While they’re more expensive initially, they can save considerable money over the life of the equipment. They’re also much better for the environment because they reduce your carbon footprint significantly. Let’s explore what you should look for when selecting your high-efficiency air conditioner.
SEER and SEER2
The Department of Energy (DOE) uses the seasonal energy efficiency ratio (SEER) to measure cooling performance. SEER indicates efficiency over a typical cooling season. That makes it useful for consumers comparing one AC to another. High-SEER ACs cost more due to the more advanced equipment. The key for most buyers is to ensure the long-term savings outweigh the added upfront costs.
SEER2 is a new version of the metric that accounts for static pressure. If purchasing a central AC, focus on SEER2 over SEER. With ductless systems, you can use either. Just be sure that you’re not cross-comparing them.
EnergyGuide Label
The Federal Trade Commission requires HVAC systems and other major appliances to have an EnergyGuide label. You’ll find this large, yellow label on the product itself. If shopping online, you can find it on retailer and manufacturer websites. The label includes all the information you need to assess energy efficiency. That includes the SEER and SEER2 ratings. You’ll also find the estimated energy use and annual operating costs.
ENERGY STAR Label
ENERGY STAR is a joint program between the DOE and the Environmental Protection Agency (EPA). The EPA sets energy efficiency standards beyond the DOE’s baseline standards. It oversees independent lab testing of ACs through a voluntary program. ACs that meet its higher standards earn ENERGY STAR certification and will display a label showing it off. That label gives you confidence that an AC performs as well as the brand’s marketing suggests it does.
Rebates and Tax Credits
Energy incentives can make a high-SEER AC much more affordable. You can search for rebates available to you by zip code via the EPA website. You should also contact your local electric company, as they’ll often have rebates and other offers available. There may also be incentives available through the government. These can include rebates, which you can sometimes claim in advance of the purchase. Otherwise, you can claim a nonrefundable federal tax credit. Note that many energy incentives require ENERGY STAR certification as a core requirement.
Variable-Speed Air Handling
A variable-speed air handler can make an AC even more efficient. Traditional blowers run at a constant speed at all times, which is inherently wasteful. Variable-speed blowers can increase or decrease their speeds depending on the current cooling needs. Note that not all ACs support variable-speed air handlers. Also, if you have a furnace, this decision will affect it as well. Often, it’s easiest to upgrade the AC and furnace at the same time.
Smart Features
You can add a programmable or smart thermostat to any AC system. Basic scheduling can lower your annual cooling costs by as much as 10%. That said, many ACs now have onboard smart features. These capabilities can enhance what a smart thermostat can do. Some of the notable features to consider include predictive maintenance and energy usage monitoring. If purchasing a smart AC, you need to ensure that the AC and thermostat are compatible.
Zone Control
If you’re considering a variable-speed air handler and a smart thermostat, you may want to consider a zone control system. These are key elements of zoned AC along with mechanical duct dampers. Zoning lets you set cooling in the different areas of your home. That approach can reduce your overall energy consumption by as much as 30%.
MERV
All ACs require at least one filter to trap particulate matter. The minimum efficiency reporting value (MERV) measures the effectiveness of that filtration. A higher MERV also increases static pressure. Most systems support up to MERV 8. Many of the top systems support up to MERV 13. A higher MERV will ensure cleaner HVAC equipment and better air quality.
