What does an air handler do? Quite simply, it handles your air. But what does that mean? Most AC units, particularly in Florida, are “split” systems, meaning they have units both indoors and outdoors. The air handler is the indoor part of your AC system—and a vital part, at that!
R-22 Freon (also called HCFC-22 Freon) is known to add to the depletion of the ozone layer. As such, the U.S. Environmental Protection Agency (EPA) has been restricting its use as of late with the intent of 100% phase-out by 2020. But what does this mean for you? Well, if you have an older HVAC unit, quite a lot, actually. Older AC units use R-22 as their refrigerant and if these systems require a repair or additional refrigerant in the next few years (or after 2020), it will be increasingly difficult to come by.
It might sound counterintuitive, but AC units do freeze over in south Florida. However, sometimes you can see the ice and sometimes you can’t. If you only feel a minimum amount of air flowing when you put your hand near a supply register, then your unit may be frozen.
For many homeowners, we only really notice that our AC unit isn’t working when it, well, stops working. We all know that when an AC system isn’t working properly, it isn’t pushing out cold air and your home—especially here in south Florida—gets more humid and uncomfortable. But, many homeowners forget that their system can still be broken, even if their home feels cool. The tips below outline some problems to be on the lookout for concerning your AC unit. If you notice anything out of the ordinary, it’s time to bring in the professionals for a system check-up.
