Want to manage air-conditioning costs in Coral Springs or Parkland? Start with how the system is used and maintained. Your FPL bill also includes other electricity use, so no single AC change guarantees a lower total. These five checks can help you identify avoidable cooling energy use while keeping comfort and humidity in mind.

3 Checks You Can Make This Week
- Review your thermostat schedule. Set a comfortable temperature when home and consider a higher cooling setpoint while away. A programmable or smart thermostat can automate the change. Avoid a setting that leaves the home uncomfortably hot or humid.
- Check the air filter. Inspect it regularly and replace it when dirty, using the size and type your system requires. A clogged filter restricts airflow and can increase energy use.
- Shade sunny windows. Closing suitable blinds or shades during strong sun can reduce solar heat entering the home. The effect depends on the window, orientation and covering.
These steps align with ENERGY STAR’s home heating and cooling guidance and the Department of Energy’s window guidance.
2 Checks That May Need a Technician
4. Have suspected duct leaks evaluated. If rooms have uneven airflow, ducts are visibly damaged, or conditioned air may be escaping into an attic, ask a technician to inspect the duct system before paying for sealing or replacement. Duct condition and location determine whether a repair is worthwhile. Learn about our ductwork service.
5. Schedule maintenance when the system needs it. A qualified technician can inspect coils, airflow, refrigerant performance and controls, then explain any finding before a repair. ENERGY STAR’s maintenance checklist describes these checks. Maintenance can support efficient operation, but the effect on a particular bill depends on the system’s starting condition.
Why Your Bill May Change
A higher FPL bill does not, by itself, diagnose an AC problem. Compare the bill’s electricity use and billing period with prior months, then consider weather, thermostat settings, occupancy and other appliances. If cooling performance or runtime has changed, document the symptoms and request an AC assessment. The Department of Energy describes how maintenance, air sealing, ductwork and thermostat settings can affect home energy use.
Common Questions
What thermostat setting saves the most?
There is no one setting that fits every household. In cooling mode, a higher setpoint generally reduces the temperature difference between indoors and outdoors, but comfort and humidity matter. Try a modest change while you are away and review both comfort and electricity use.
Should I replace my AC just to lower the bill?
Not based on one bill. A technician should assess equipment condition, repair history, sizing, ductwork and current performance. Compare a written repair or replacement estimate against your actual electricity use before deciding.
Compare usage before comparing bill totals
Keep the actual electricity-use information from your bills alongside the amount charged. A higher payment does not, by itself, identify an air-conditioning fault. Billing periods can differ, and changes in household use may matter. Start with the information your bill provides and avoid attributing the entire change to one appliance without investigation.
Write down the dates covered, electricity use and any significant changes in occupancy or how the home was used. A house occupied throughout the day is a different comparison from one that was empty during working hours. Record changes rather than guessing how much each one contributed. This creates a more useful starting point for discussing whether the AC also needs an assessment.
Keep a practical comfort and operating log
For several ordinary days, note the thermostat setting, rooms that feel uncomfortable and any unusual operation you observe. Do not repeatedly change settings just to force a particular result. The purpose is to describe normal use and identify a pattern. A technician can use that information alongside an equipment inspection when a performance concern warrants one.
If only one room is uncomfortable, identify it separately from the overall bill concern. If airflow has changed or the system has started making an unfamiliar sound, record those observations too. A utility bill cannot diagnose an equipment problem, and a symptom cannot identify the amount of energy it may be using. Keeping the issues separate helps the service discussion address each one appropriately.
Make one manageable change at a time
Choose changes you can apply consistently and safely, such as keeping accessible grilles clear or following the equipment’s filter instructions. Record when the change was made. If you change several habits and replace equipment at the same time, it becomes difficult to understand which changes affected the experience. You do not need to turn your home into a testing project to keep a useful record.
Avoid making an energy-saving target more important than comfortable, appropriate use of the home. Do not block vents, interfere with safety controls or keep operating equipment that shows an electrical or water problem merely to complete a comparison. If a new symptom needs service, describe it and arrange a diagnosis rather than trying to settle the issue from a bill alone.
Ask what an inspection will answer
When requesting service, explain whether the concern is a recent increase in use, poor cooling, uneven airflow or a combination. Ask what the assessment includes and what information would help the technician. Keep maintenance records and previous repair invoices available. A clear service request is more useful than asking for an assumed repair based only on a high bill.
If work is recommended, ask how it relates to the findings and what remains uncertain. A proposal should explain the problem being addressed without guaranteeing a particular future bill. If replacement is discussed, compare the full scope and the assumptions behind any operating-cost estimate. An efficiency rating is useful equipment information, but it is not a personalized savings forecast.
Review results over a meaningful period
After a change or completed repair, continue keeping ordinary usage records. Avoid drawing a broad conclusion from one unusually hot day or a bill covering a different period. Record any simultaneous household changes so the comparison remains understandable. The goal is a useful account of what happened, not proof of a promised percentage reduction. Bring unresolved comfort or performance concerns back to the service team with the relevant dates and observations.
