It seems like every summer, your energy bill is higher than the year before. You know running the AC uses a lot of power, but you’re worried your system may be getting less efficient over time. Here are a few signs you have poor AC efficiency — and what to do about it.
- Too much humidity. Your AC naturally removes the moisture from the air as it cools. If you find that you’re still feeling clammy or sticky, even when the air is running, it may mean your refrigerant is low. This in turn makes it take longer to cool your home, wasting energy in the process. Call your HVAC technician to check your refrigerant level and recharge it if necessary.
- Short-cycling. If your AC turns on and off frequently, it’s definitely wasting energy. There could be several possible causes. First, check your air filter to see if it needs to be replaced. Then, use a thermometer to calibrate your thermostat and see if it’s reading the correct temperature. If neither of these issues is the culprit, it could mean your AC is too big for your home. Call your HVAC technician to discuss your options.
- Running too long. If instead of short-cycling, your system simply won’t turn off, that’s also a sign of poor AC efficiency. The longer it runs, the more energy you waste. See if the air coming from your vents is cold or warm. Then check the airflow from your system and change the filter and patch up any ductwork leaks. The problem may also be that your AC is too small. Call your HVAC technician to ascertain the problem and see what can be done.
- Temperature fluctuations. An efficient unit should cool your home evenly. Is one room warm and another cool? Your system may need maintenance, or there could be a problem with your ductwork design, which will affect AC efficiency. You may also consider a zoning system to get better air distribution throughout your home.
