A central air system that’s too small for your home can lead to discomfort, inefficient operations, and higher energy bills. Here at North Shore Fuel, we want to help you stay cool and comfortable all summer long, and we’re sharing five signs that your air conditioner might be undersized.


  1. High energy bills: An AC unit working overtime to cool your home will use more energy, leading to spikes in your electricity bills.
  2. Constant running: If your AC runs for hours on end without reaching the desired temperature, it’s struggling to keep up with your home’s cooling needs and likely undersized.
  3. Poor airflow: Weak or inconsistent airflow from your vents is a sign your AC might not be powerful enough to circulate cool air throughout your home. If you’ve checked and changed your air filters and are still not getting good airflow, give us a call.
  4. Uneven cooling: Do some rooms in your home feel cooler or warmer than others? An undersized AC might cool certain areas effectively while leaving others uncomfortably warm.
  5. Increased humidity: In addition to cooling your home, your AC unit also helps remove moisture from the air. If your home feels muggy or sticky even while your AC is running, it could be a sign of insufficient cooling capacity.
