Your summer electric bills in Florida will likely be the highest bills if you compare the dollar amounts throughout the year. I can say this from personal experience. Here are a few tips to keep you cool this summer and your air conditioning system working properly.
1) Check your air intake filter monthly. I know that this sounds excessive, but it is not. You will be surprised how many airborne pollutants are in your house all of the time. If it is dirty, change it. They are usually located under the air handler unit, in the hallway ceiling or wall. I also pour bleach in my condensation line to keep it clear from algae build up that may prevent proper drainage. Good time also to check the condensing unit has adequate clearance around allow for ventilation! Keep plants trimmed back 2ft from the unit and check that the condensate line is free from obstruction.
2) Set your thermostat to 78 degrees while you are at home and 83 degrees while you are away. When home and tempted to go lower the 78, first try turning the unit’s fan from the auto setting to "on". The circulation may help with hot spots and save on cost. When leaving, there is no reason to run the ac when you are at work.
3) Go programmable! To help remember to turn the temp up, consider installing a programmable thermostat. This feature allows you to set your A/C to turn on 30 minutes or so before you expect to get home.
4) Use your shades, install some heavy curtains or light blocking shades. Closing the shades prevents additional sun rays from heating up the air inside of your house.
5) Use fans. It really doesn’t matter whether it is a ceiling fan or an oscillating fan as long as it moves air. Moving air appears to feel cooler than still air. However, remember to turn the fans off when you leave the room.
6) Have your A/C unit coils cleaned and inspected by a certified technician. You may need to have the air conditioner coils cleaned periodically as they develop a dirty buildup. During the same service call have the freon levels checked as it may be low due to a leak in the system.
