Maybe your aging air conditioner cools well enough, but is costing you a fortune every summer in electric bills. (And in Florida, summer is pretty much the whole year.) You’re probably aware that replacing your system can cut those costs by reducing AC power consumption. That’s true if your system is more than 8 years old, because new systems are far more efficient. However, the cost of a new system might seem excessive, especially if your old one still works. We have some options.

The good news is there are ways you can reduce AC power consumption by improving the efficiency of your old equipment. Such relatively small fixes as these can lower electric bills and buy you some time until you’re ready to spend the money on a new system.

1. Replace or clean air filters regularly. This is a simple and inexpensive task you can do yourself. When air filters get clogged with dust and particulate matter, they impede the flow of air within the system, which forces it to work harder to achieve a set temperature.

2. Make sure all vents are open. If even one vent is closed, it can make it more difficult to cool your entire home, since the warm air from the room with the closed vent will mix with the cooled air from the others.

3. Check the thermostat; be sure it is set to Cool, and replace the batteries if necessary. If your thermostat isn’t battery powered, or if a battery replacement doesn’t resolve the problem, reset the thermostat according to manufacturer instructions. If resetting the thermostat doesn’t solve the problem, check your indoor electrical system. Make sure your breakers are all set to “on” and be sure to check for any tripped circuits.

4. If you don’t already have one, install a programmable thermostat. Programmable thermostats cut energy usage by adjusting temperatures while you’re away or asleep. You can program them yourself or purchase one that slowly adapts to your temperature preferences. Some can even be set up with an app away from home.

5. Filter or block sunlight with tree plantings, Bahama shutters, or window shades or blinds, as well as window films that reflect back light. Some of these are pricier than others, but their benefit is lasting.

6. Insulate the walls and attic. This applies especially if you have an older home, which might not be properly insulated. The addition of robust insulation can make a noticeable difference in temperature and sound reduction in your home.

7. Get an inspection and tuneup of your system. This is a relatively easy fix, and includes changing filters, cleaning coils, and a full system and duct work inspection. The Air Rescue technician will make recommendations that can improve cooling.

8. Finally, consider a new AC unit. Air Rescue has easy financing and easy payments to help you afford a new AC. You will be surprised at the savings and peace of mind.
