Most modern air conditioners have a SEER between 13 and 21—the minimum standard SEER is often 13. An air conditioner with a higher SEER provides a higher level of comfort, typically because it will have two features: a two-stage or variable-speed compressor and a variable-speed blower. These features allow the system to make slight adjustments in speed to maintain the temperature and avoid turning the system off and on frequently, which is an energy- draining process. 3 How can your HVAC help you save energy and money? An energy-efficient system can help you keep money in the bank. If your HVAC unit was installed in 2006 or earlier, you could see as much as 54% in energy savings by upgrading to one of today's units. Upgrad- ing to a system with a higher SEER of 16 or above also helps. Look for a variable-speed system that continuously adjusts the motor speed for greater efficiency while maintaining your desired temperature. This quiet variable- speed HVAC system offers that consistency as well as advanced humidity control. Note that your home's size and ductwork condi- tion also affect energy efficiency. 4 How do you address hot and cold spots in your home? If you're peeling off layers in one room and piling them on in another, evaluate your system type. A variable-speed or two- stage system will provide a more consistent level of heating and cooling across your home because they run on the lower stages more frequently and keep air moving in the house.. Consider a ductless system for addi- tional comfort in spaces without ductwork, such as basements and garages. If the problem areas are linked to your ducted HVAC system, consider zoning your home and installing a thermostat to con- trol each space. A central control panel then regulates the temperature in each zone by activating dampers, these dampers are like a faucet for your system, opening and closing to control the airflow to each zone. 5 What are the benefits of a smart thermostat? Designed to make life easier, a smart ther- mostat allows you to control and schedule your HVAC settings from anywhere using your smartphone, tablet or computer. It can also provide a way for your HVAC profes- sional to constantly monitor the health of your system and alert you before potential problems arise. Most smart thermostats offer zoning capabilities; some even offer perks such as built-in humidity sensors, maintenance and filter service reminders, five-day weather forecasts, as well as other alerts and radars.
