Florida’s intense heat and humidity relentlessly challenge air conditioning systems. Long summers, frequent heat waves, and high moisture levels force HVAC equipment into overdrive to maintain indoor comfort. Understanding these climatic pressures is the first step toward year-round efficiency, and this guide will explore the chief reasons behind the extra pressure on your air conditioner during Florida’s summer.
High Humidity Levels
High humidity levels force your air conditioner to work harder because your system must cool the air in addition to removing excess moisture in your living space. When indoor humidity is high, your AC runs longer cycles to reach and maintain the desired temperature and comfort level. This increased workload leads to greater energy consumption and puts more strain on components like the compressor and evaporator coil. Over time, this stress and strain on the system can reduce its efficiency, increase wear and tear, and shorten its lifespan if not managed properly.
To prevent this, you will want to consider a variable-speed air conditioning unit for your home. This unit runs at slower speeds so that it can pull the humidity from the air more easily than a fast-running unit. Also, use ceiling fans in your living space to help circulate the air. This reduces the temperature in the direct area and makes you feel cooler.
If humidity levels are still not as low as they should be, consider installing a whole-home dehumidifier that will focus on removing the moisture from the air and give your AC a little break. At Ahoy! Cooling & Heating, we can help you decide whether installing one of these units will be beneficial in your home.
Temperature Difference
In Florida, the significant temperature difference between the hot, humid outdoors and the cooler indoor environment places extra strain on your air conditioner. When outdoor temperatures soar into the high 90s or higher, heat constantly tries to move into your cooler home. Poor insulation, leaky windows, or frequently opened doors allow this heat to seep in, forcing your AC to run more frequently and longer to maintain your desired indoor temperature.
The greater the temperature gap, the longer it takes for your AC to remove heat from the air. If the temperature difference is too large, it may short-cycle, causing the unit to turn on and off repeatedly. This reduces efficiency and can lead to premature system failure. When the temperature outdoors is above 95 degrees Fahrenheit, keeping your indoor temperature slightly higher will minimize the temperature difference and keep the AC from overworking.
Blocked Airflow
Blocked airflow restricts the ability of your air conditioner to circulate air efficiently, forcing the system to work harder and longer to cool your home. With obstructed airflow, caused by clogged filters, closed vents, or blocked ductwork, cool air can’t move freely through your home. This means rooms stay warmer longer, causing the AC to run extended cycles to reach the thermostat setting.
Prolonged operating times and higher internal pressure from restricted airflow can overwork key components like the blower motor and compressor. This accelerates wear, reduces lifespan, and increases the likelihood of breakdowns in your cooling system. Insufficient airflow over the evaporator coils can cause them to become too cold and freeze. When this happens, your HVAC system can’t cool the air properly and may shut down.
Blocked airflow prevents balanced distribution of cool air, creating hot and cold spots throughout your home. This often results in adjusting the thermostat lower than necessary, further increasing strain on the system. Maintaining clear airflow through regular filter changes, duct inspections, and unobstructed vents helps ensure your AC operates efficiently and avoids unnecessary overwork. We recommend changing your air filters every two to three months to make sure the air in your home flows freely. You must also make sure no furniture, curtains, or rugs are blocking your vents.
Thermostat Issues
Thermostat issues can make your air conditioner work overtime by disrupting communication between the thermostat and the AC system. Older or incompatible thermostats may not work well with modern AC systems, especially those with variable-speed or smart capabilities. If a thermostat misreads the indoor temperature, due to poor placement in direct sunlight or internal sensor malfunctions, it may signal the AC to continue running even when it reaches the desired temperature.
A thermostat that fails to respond to input changes or scheduled settings can prevent your system from shutting off or adjusting properly. This often causes the AC to run at full capacity for longer, particularly during hot Florida summers. In addition, an improperly calibrated thermostat may inaccurately register room temperatures. As a result, the AC could cycle too frequently or run longer than necessary, leading to excessive energy use and increased system wear.
Incorrect Unit Size
An incorrectly sized cooling unit, whether too large or too small, can also cause your HVAC equipment to work overtime. A cooling system that’s too small for your home will struggle to reach the set temperature, especially during peak heat in Florida. As a result, it will run continuously or for extended periods, wasting energy. While a larger unit may cool a space quickly, it often shuts off before properly dehumidifying the air. Proper sizing is especially important for moisture removal in Florida’s humid climate.
Low Refrigerant
Low refrigerant levels force your air conditioner to work overtime by reducing its ability to absorb and transfer heat effectively. When levels are low, the system can’t cool the air as effectively, causing it to run longer cycles in an attempt to reach the desired temperature. Since the system must run longer to compensate for the decreased cooling efficiency, it consumes more electricity, leading to higher utility bills. Low refrigerant undermines the entire cooling process, making your air conditioner work harder. Regular maintenance and timely leak detection or refrigerant issues are key to ensuring long-term system health.
Low refrigerant levels can also cause the compressor to overheat. This is an expensive component to repair, so ensuring that the refrigerant levels in your system are where they need to be is imperative.
If you believe that you have a refrigerant leak, do not try to repair the problem yourself. Refrigerant is toxic to the environment and your health, and inhaling it can lead to serious health concerns. Contact one of our team members at Ahoy!
