Energy-Efficient Cooling Tips for Florida Homes with Older AC Systems

November 25, 2025 by Laura
AC Systems

In Florida’s hot and humid climate, it’s no secret that there is constant demand on AC systems for homeowners and business owners alike. Older units especially face challenges that can lead to inefficiency, frequent breakdowns, and higher energy bills that feel overwhelming as the year-round sun beats down.

At Frostys AC, your #1 AC company in Riverview, we understand the importance of boosting efficiency for your AC system. Below are some of our top tips to help keep your home cool and your energy costs under control.

Maximize Airflow and Ventilation

Maximizing airflow and ventilation helps your AC system run more efficiently and keeps your home cooler overall. To do this, make sure vents are not blocked by furniture or curtains, and leave interior doors open to promote circulation.

Another great way to boost airflow is by using ceiling fans. Not only do they enhance air movement throughout the house, but they also help reduce reliance on your AC by making rooms feel cooler than they actually are. This helps lower energy bills in the long run.

Improve Home Insulation 

Think of attic insulation as your home’s sunblock: It keeps the Florida heat from sneaking in and melting cool air away. Sealing air leaks around windows, doors, and ductwork is like plugging up the escape hatches your AC can escape from.

Weatherstripping can help too, which is a sealing material placed around doors and windows that gives your home an extra boost in efficiency. With these upgrades, your AC won’t have to work as hard, resulting in a cooler home and lower energy bills.

Use a Programmable or Smart Thermostat 

Programmable and smart thermostats are all the craze, and for good reason. With the ability to control your home’s temperature automatically, energy-efficient cooling becomes much easier. 

For example, if you raise the thermostat when you are away or asleep, your AC will not run unnecessarily. For even better efficiency, you can set temperature schedules such as keeping it a few degrees higher during the day when no one is home, and lowering it again once everyone is back. 

Another great aspect about smart thermostats is that they learn your routine and help you understand your energy use. That way, it is easy to notice patterns, tweak the settings, and save money without giving up comfort.

Regular AC Maintenance 

Regular AC maintenance is essential for helping your AC system run without having to work overtime. One of the most important things to stay on top of is your air filters. Since they tend to get dirty quickly from dust, pollen, and even pet hair, it’s best to change them every 1–3 months for optimal airflow.

It’s also a good idea to schedule professional tune-ups with an AC company in Riverview at least once a year to make sure everything is working the way it should. If you are ready for an annual tune-up, Frostys AC offers the best AC service in Riverview to keep your system healthy and energy efficient.

Lastly, don’t forget about cleaning the condenser and evaporator coils. Keeping them clear improves airflow, reduces strain on your system, and lowers energy use. If you are unsure how to go about this, be sure to call in the pros at Frostys for reliable help.

Shade and Window Treatments

Shade and window treatments are the simple yet effective ways to help save energy and keep your home cooler. Options like blackout curtains, blinds, or UV-reflective window films will help block out the heat before it enters your home. 

You can also reduce solar heat gain by planting shade trees or installing awnings around sunny windows. And for an easy everyday habit, keeping your blinds closed during peak sun hours is a great way to help give your AC a break.
