Why is my AC running constantly?

In Florida, it is extremely common for air conditioners to run for long cycles during peak summer months. When temperatures stay high day and night, your system works continuously to maintain your thermostat setting.

However, constant running can also signal an issue, such as:

  • An undersized or aging system
  • Dirty air filters are restricting airflow
  • Low refrigerant levels
  • Poor insulation or air leaks in the home
  • Thermostat settings that are too low

If your system never seems to shut off, it’s worth having it inspected. A quick diagnostic from Coastal Climate Experts can determine whether your system is operating normally or overworking due to a repair issue.

What temperature should I set my thermostat to in Florida?

For most Florida homes, the recommended summer thermostat range is 74°F to 78°F when you are home. This range balances comfort and efficiency while preventing unnecessary strain on your AC system.

When you’re away, raising the temperature by a few degrees (or using a programmable thermostat) can significantly reduce energy costs.

Keep in mind:

  • Lower settings do not cool your home faster
  • Extremely low temperatures increase energy bills and wear on your system
  • Consistency is better than frequent adjustments

If your home still feels warm at recommended settings, your system may need maintenance or repair.

Why does my house feel humid with the AC running?

If your home feels sticky or humid even while the AC is on, your system may not be properly removing moisture from the air.

Common causes include:

  • Oversized AC system that cools too quickly without dehumidifying
  • Dirty evaporator coils reducing moisture removal
  • Poor airflow due to clogged filters or duct issues
  • Low refrigerant levels are affecting cooling performance

Florida humidity is intense, so your AC system must actively dehumidify, not just cool the air. If indoor moisture levels feel uncomfortable, it’s a sign your system needs attention.

Stop living with sticky air. Schedule a humidity and airflow evaluation with Coastal Climate Experts.

How often should I change my air filter?

In Florida, air filters should typically be changed every 30 to 60 days, depending on usage, pets, and indoor air quality.

You may need more frequent changes if:

  • You have pets that shed
  • Your AC runs constantly during summer
  • You notice dust buildup or reduced airflow
  • Someone in the home has allergies or asthma

A dirty filter is one of the most common causes of AC strain and inefficiency. Regular replacement helps prevent breakdowns and improves air quality.

Is it normal for my AC to run all day?

Yes. During peak Florida heat, it is normal for air conditioners to run for extended periods, especially in homes with high cooling demand.

However, there is a difference between normal long cycles and inefficient nonstop operation.

It may NOT be normal if:

  • Your home never reaches the set temperature
  • The system runs constantly but cooling is weak
  • Energy bills spike unexpectedly
  • Rooms cool unevenly

These issues often point to system inefficiency, maintenance needs, or repair problems.

Why is my AC blowing air but not cooling?

If your system is running but the air is not cold, it could indicate several problems:

  • Low refrigerant levels
  • Frozen evaporator coil
  • Compressor issues
  • Dirty coils or restricted airflow
  • Thermostat malfunction

This is one of the most common AC repair calls in Brevard County during the summer. The sooner it’s diagnosed, the more likely it is to avoid a full system breakdown.

Why is my energy bill so high in summer?

High Florida electric bills are usually caused by extended AC usage, but spikes often point to inefficiency.

Common causes include:

  • Dirty filters restricting airflow
  • Leaky ductwork
  • Aging or failing system components
  • Poor insulation in the home
  • Thermostat settings too low for extended periods

A properly functioning AC system should cool efficiently without extreme energy spikes.
