Air conditioners provide essential cooling during hot and humid months, but can consume immense amounts of electricity. With energy costs steadily rising, many homeowners are motivated to find ways to run their ACs more efficiently and reduce expensive electricity bills. Thankfully, several effective strategies exist to minimize air conditioner power usage without sacrificing comfort. With smart maintenance, upgrades, and operational changes, you can keep your home cool while going easier on your energy budget.
Improve Air Sealing And Insulation
An important starting point for enhanced AC efficiency is sealing any air leaks and improving insulation around your home. This keeps the cooled air inside your house instead of escaping outside. Inspect windows, doors, vents, and outlets for drafts or gaps that allow conditioned air to flee. Use caulk, weatherstripping, and insulation sealants to plug leak sources. Also, upgrade attic and exterior wall insulation to recommended levels for your climate zone. Stopping avoidable air loss minimizes the workload for your AC system.
Clean Filters, Coils, And Fins
If you know how does an air conditioner work, then you’ll also know that clean AC free of blockages pulls less electricity while operating. This is because debris on air conditioner components obstructs airflow and reduces heat transfer efficiency. Routinely clean out dust and dirt from the filters, condenser coils, fins, and evaporator coils to maximize airflow. Straighten any bent fins gently with a fin comb. Also clear plants, bushes, and debris away from the condenser outside. A professional deep clean of your entire AC system every few years removes built-up gunk for lower energy demands.
Install A Programmable Smart Thermostat
Replacing your old analog thermostat with an app-controlled smart thermostat allows much more customization of cooling operations based on your lifestyle and schedule. Smart thermostats learn your habits and adjust temperatures accordingly when you are home or away to conserve energy. Set a wider temperature range or turn the AC off entirely when traveling. Geofencing features detect when you are approaching home to restore desired temperatures right on time. Programmable scheduling also eliminates excess runtime.
Upgrade To A Newer, Higher Efficiency Model
If your AC unit is more than 10 years old, replacing it with a new Energy Star-certified model can dramatically curb electricity usage. The newest AC units operate at over double the SEER (Seasonal Energy Efficiency Ratio) of older models. Higher SEER ratings, currently up to 23 SEER for the most efficient window ACs, mean using far less energy to achieve the same cooling compared to outdated units with SEER ratings of 6 to 10. Investing in a modern, green AC pays off quickly in energy savings.
Optimize Use Of Ceiling Fans
Strategic use of ceiling fans in conjunction with your AC system reduces runtime significantly. Ceiling fans cool people directly by creating a wind chill effect. Set your thermostat a few degrees higher and use ceiling fans to maintain comfort. This takes the pressure off the AC so it cycles on less frequently. Fans also circulate cooled air evenly through spaces. Just remember to adjust fan direction; downward in summer for wind chill and upward in winter to recirculate warm air trapped near ceilings.
Improve Attic Ventilation
Proper attic ventilation releases built-up hot air, lowering temperatures before this heat can permeate into living spaces and force ACs to work overtime. Install ridge, gable, and roof vents to create effective airflow pathways for hot air to escape. Power attic fans ventilate attics rapidly compared to stationary vents alone. Make sure attics stay properly ventilated year-round, and insulate any ductwork and HVAC components passing through attic spaces to protect from external heat sources affecting efficiency.
