In our past two posts, we wrote about the importance of having regular AC maintenance each spring. We could post plenty more about this topic, since it’s that important—you can have most of your potential AC problem vanish thanks to keeping up with maintenance. There is one AC problem you can’t avoid this way, however, which is that the time will come when your air conditioner must be replaced. Maintenance will postpone that day, but no cooling system can last forever, no matter how much care it receives.
This year might be the year. You schedule maintenance with our technicians, we examine the AC, and explain that it’s not likely to last much longer unless it has expensive repairs—repairs that won’t be worth it compared to replacing it with a new AC.
This sounds a bit like a Christmas request (we don’t think Santa can cram a new central air conditioning system down your chimney, and we also doubt he has the proper certifications to accurately size it), but it may be a big question you’ve got for the upcoming season. You know that the current AC you have is near the end of its service life, and trying to push it through another summer in Florida may end in disaster. 
One of the common problems with 
Your air conditioning system has two fans that are essential for it to work. The fan you’re most used to hearing and feeling is the indoor blower fan. This fan is located at the bottom of the HVAC cabinet, where it pulls air from the return air ducts and then pushes it past the evaporator coil, where it’s cooled, and then into the ventilation system.
Summer never truly ends in Florida. We move through rainier, cooler periods, but the work of an air conditioning system in a Florida home is never fully done for the year.
Summer is just around the corner for most other parts of the country. For us, though, seasons are a more nebulous concept. You’ve probably already been using your air conditioner for weeks, and you’ll be relying on it pretty heavily over the next couple of months. Air conditioners suffer a lot of stress in places like Florida, especially during the summer. No amount of care and maintenance can keep them operating forever, either. That’s why you need to know when it’s time to replace your air conditioner with a new one. If your AC sounds like it fits the points below, you should consult with a professional about getting rid of it. 
You may not think about the refrigerant in your air conditioner very often (or at all.) However, it’s still a very important part of keeping your system running properly. In fact, without refrigerant, your air conditioner wouldn’t be able to absorb heat and vent it out of your home.
