One of the easiest things to do to improve your system’s efficiency is to change the air filter(s) associated with your system. This allows the system to operate without having to draw (work) harder to get air through the ductwork.

Another simple task is to make sure the outdoor unit (condenser) is not obstructed by plants or structures that might impede air flow. A tree shading the unit helps keep it a bit cooler, making its job easier, but fallen leaves clogging the in and out flow can decrease efficiency. Check the owner’s manual and make sure the power is shut off to the unit if you intend to do any work to clear debris from the surface.

The indoor unit of the AC is the air handler. This is where the real chilling takes place. Within this unit is the evaporator coil which is a virtual dust magnet. This coil is often moist due to normal condensation. The moisture traps dust and dirt and must be kept clean to work efficiently. Again, refer to your owner’s manual and shut the power off to the unit if you intend to do this easy maintenance.

There are other common-sense measures you can take to keep your system running smoothly. Draw the blinds across west-facing windows to shield them from blaring afternoon sun. Use ceiling fans (only when you are in the room.) A thermostat set at 76˚ will feel like 72˚ with the cooling breeze created by these Florida fixtures. Installing a an EnergyStar® rated programmable thermostat is another DIY task that could help make your system run more efficiently and save you some money!
