Living in a hot weather state means you use your central air nearly year-round. The tropical environment here is hot and humid, with heat indexes soaring over 100°F in summertime. Your air conditioner becomes your best friend, keeping your home cool and comfortable night and day.
Your AC is running much more than usual. Extended run times are expected on intensely hot days. How do you know when the system’s constant operation is by more than a few hot days?
When It’s Normal for Your Air Conditioner to Run More Often
It’s not unusual for air conditioners to run more frequently, especially in June, July, and August. Energy use increases significantly during hot summer months, so if your air conditioner runs constantly without shutting off, it may indicate an underlying problem. Addressing this promptly can improve efficiency and prevent higher energy costs.
A few reasons why your AC may be running 24/7:
High Outdoor Temperatures:Â When the outdoor temperature is significantly higher than your desired indoor temperature, your AC will stay on to keep your home cool. The temperature of your attic also significantly affects AC use, as a hotter attic can increase the overall temperature of your home, causing the AC to work harder and run longer.
Humidity Levels: Florida is also known for its extremely high humidity levels. Your air conditioner not only cools the air but also removes excess moisture. This process can cause longer run times, especially when the humidity is above 70%. It’s not unusual for South Florida to see humidity levels over 90%!
Large Living Spaces: If you have more square footage, your AC must work harder and longer to cool the ample space. Homes with open floor plans or multiple stories can also contribute to longer AC run times.
When Should I Be Concerned About How Long My AC Has Run?
While it’s normal for your AC to run more often in Florida, some signs indicate a cooling problem:
Inconsistent Temperatures: If your home has hot and cold spots, your AC may struggle to distribute cool air evenly.
High Energy Bills: A sudden spike in your energy bills can indicate that your AC is running inefficiently. Various issues can cause inefficient cooling, including a need for maintenance or repair.
Short Cycling: If your AC turns on and off frequently without completing an entire cooling cycle, it does what HVAC techs call “short cycling. This issue puts additional strain on your system and reduces its lifespan.
Unusual Noises: Strange sounds, such as grinding, squealing, or banging, are often mechanical issues that require immediate attention.
What is Causing My AC to Run Constantly?
Several issues can cause your air conditioner to run constantly. Understanding them can help you identify and address the problem promptly.
Poor Insulation: Inadequate insulation in your home allows cool air to escape and hot air to enter, making your AC work harder to reach and maintain the set temperature.
Leaky Ductwork: Old or damaged ductwork may leak cool air into your attic space before it reaches your living space. This inefficiency forces your AC to run longer to compensate for the lost air.
Airflow is Restricted: Clogged or dirty air filters, closed vents or a bad motor can all restrict airflow, making it difficult for your AC to circulate cool air effectively. Air conditioners must ” breathe ” to cool your home properly.
Thermostat Issues: Malfunctioning thermostats may not signal your AC to turn off at the right time, leading to constant running.
Old or Inefficient System: An older or inefficient AC system may struggle to keep up with your home’s cooling demands, especially during peak summer months.
Undersized AC Unit: An air conditioner that is too small for your home’s square footage will never keep you cool and comfortable. If the system is less than 17 seer, you must consider upgrading the cooling system. If your unit is newly installed and was sized incorrectly, your HVAC system may continuously run because it can’t handle your home’s square footage.
Schedule An HVAC Inspection If Your AC Is Working Overtime
Regular HVAC inspections and maintenance are essential to ensure your air conditioner operates efficiently and effectively. A professional technician can identify and address issues such as:
- Cleaning and replacing air filters
- Inspecting and sealing ductwork
- Checking and calibrating the thermostat
- Evaluating the overall condition of your AC system
Scheduling routine maintenance helps prevent minor issues from becoming major, costly problems. Proper maintenance also extends the lifespan of your AC unit and ensures your home remains comfortable for you and your family all summer.
While it’s normal for your AC to run more in Florida’s hot and humid climate, excessive run times can indicate underlying problems that a professional HVAC technician can diagnose and resolve. Recognizing and promptly addressing system issues can help keep your air conditioner running smoothly and efficiently, even on the hottest days.
