How a Poorly Maintained AC System Can Lead To Higher Energy Bills

If your energy bills have been creeping up this summer, your air conditioning system might be to blame—especially if it hasn’t had regular maintenance. A poorly maintained AC has to work harder to cool your home, using more electricity in the process. Because AC systems account for about 12% of our annual energy use (per the US Department of Energy), it’s important to pay attention to problems with your AC system that could be quietly driving up your energy costs. Here are four common issues that might be costing you more than you think:

dirty condenser coils

The condenser unit, located outside your home, releases the heat your system pulls from inside. When the coils are coated with dirt, dust, or debris, the AC can’t release heat efficiently. This forces the system to run longer cycles to cool your home, using more electricity and putting extra wear on your equipment. According to the US Department of Energy, dirty condenser coils can increase energy costs by 30%. This highlights the importance of proper cleaning and maintenance not only for the health of your cooling system, but also that of your wallet. 

Low refrigerant levels

Refrigerant is the lifeblood of your air conditioning system. If levels are low due to a leak or improper charge, your system can’t absorb and move heat effectively. That means your AC will struggle to keep up with the thermostat, running longer and using more power—without giving you the comfort you're paying for. Based on a report by the Air Conditioning Contractors of America, low refrigerant can cost you 20% on energy costs. 

dirty or clogged filters

Your air filters trap dust, pollen, and other pollutants to keep your indoor air clean. But when they get clogged, airflow is restricted, which makes your system work harder to circulate air. The result? Higher energy usage and a greater chance of system failure. Replacing filters every 1–3 months can make a big difference in efficiency, since dirty filters can cause your system to consume 15% more energy (US Department of Energy). 

COMPROMISED OR LEAKY DUCTWORK

If your ducts are leaking or poorly sealed, a significant amount of cooled air may never reach your living spaces. Inevitably, your AC will compensate by running longer to cool your home, wasting energy in the process. In fact, leaky ducts can reduce efficiency by as much as 30%! (US Department of Energy). Even just 20% of air conditioned air being leaked in your ducts can result in your cooling system working 50% harder. This can easily add hundreds of dollars a year to your utility bills.
