There’s nothing more frustrating than coming home on a sweltering Clarksville summer day only to find your air conditioner blowing warm air—or worse, barely working at all. If your A/C isn’t keeping your home cool, you’re not alone. Here are some common reasons your air conditioner might be struggling and what you can do about it.
AC not keeping up? It’s likely from one of these reasons:
Dirty Air Filter
One of the simplest and most common issues is a clogged air filter. When filters are dirty, they restrict airflow, making it harder for your A/C to circulate cool air.
Refrigerant Issues
Refrigerant is the substance that your A/C uses to absorb heat from your home. If your system is low on refrigerant due to a leak or improper charge, it can’t cool your air effectively.
Blocked or Leaky Ductwork
If your ductwork is leaking or blocked, cool air may not be reaching the rooms where you need it most. Leaks can cause up to 30% of your cooled air to escape, especially if the ducts run through unconditioned spaces like attics or crawlspaces.
Aging or Undersized Unit
Older units often lose efficiency and may struggle to keep up with high temperatures, especially during heat waves. If your A/C is more than 10–15 years old, or if it was improperly sized for your home, it may not be capable of handling your cooling demands.
Thermostat Issues
Sometimes if you’re AC isn’t keeping up, the problem isn’t with your A/C at all, but with your thermostat. If it’s not reading the temperature correctly or is located in a spot that gets direct sunlight, your system may be cycling on and off at the wrong times. Consider upgrading to a smart thermostat for more accurate and energy-efficient control.
Dirty Coils
The evaporator and condenser coils in your A/C system need to be clean to operate efficiently. If they’re covered in dirt or debris, heat transfer becomes less effective, and your system can overheat or freeze up.
Poor Home Insulation
Even the best A/C can struggle if your home isn’t well insulated. Air leaks around windows and doors, poor attic insulation, and unsealed ducts can all let hot air in and cool air out. A home energy audit can identify problem areas and help you make improvements that boost comfort and reduce energy bills.
