No air conditioning system is “the last AC you’ll ever need to buy.” No matter how well you maintain your home’s cooling system, it will need to be replaced at some time. It’s a matter of knowing when: If it be not now, ‘tis to come. If it be not to come, it will be now. If it be not now, yet it will come. The readiness is all.
Now Let’s See If Your AC Is Ready
How can you know your aging air conditioner is at the replacement stage? Thankfully, ACs give off several signs they’re in decline, and there are a few other factors to consider when you’re debating about putting a new air conditioner.

When your home’s air conditioning system is running during the hot and humid Florida summers, you’ll occasionally hear a sound of water dripping inside it. This is a normal part of the AC’s operation: it’s the sound of water falling from the evaporator coil and going down a condensate drain.
Short answer: Probably not. You can lower them.
The modern air conditioning system is a complex piece of refrigeration equipment. Actually, electromechanical air conditioning has always been complex: newer systems have added on more computerized parts and taken away refrigerants that are toxic or explosive, so although you aren’t likely to cause an explosion by tinkering with an air conditioner on your own, you’re likely to make whatever is wrong with it much worse. You want only licensed and trained HVAC professionals to handle any 
Is your AC turning on and off again? It’s definitely not normal.
You may have heard of ductless mini splits. Ductless heating and cooling is popular in Europe and Japan, and is now making inroads here in the US. If you’re thinking of installing a new cooling system before the major summer heat arrives, going ductless might be a good option. But ductless mini split heat pumps (that’s another term for them) are not ideal for every home.
Temperatures are rising in Florida, but the rain is also falling, so we aren’t quite into the full heat of summer yet. Your utility bills won’t show the price spike you expect when your air conditioning system starts running on a regular basis.
We often recommend UV air purifiers to our customers who are looking for the best in indoor air quality. UV air purifiers use the power of ultraviolet radiation, the same energy that comes from the UV rays in the sun, to kill organic pollutants moving through a home’s HVAC system. This includes bacteria, germs, viruses, and mold spores. UV air purifiers are especially helpful for the Florida climate, which is humid enough to make it easy for many unpleasant organic pollutants to thrive. Mold in particular is a problem that can get into many ventilation systems, where it not only releases unhealthy mold spores but can create damage to the ductwork.
One of the most important services that we offer our customers is routine maintenance service for their cooling and heating systems. We strongly recommend homeowners arrange for a maintenance tune-up and inspection in spring for their air conditioning systems. The work we do on your AC, such as tightening electrical connections, lubricating moving parts, and checking for a drop in refrigerant pressure, will give the system the best chance of making it through another sweltering Florida summer without suffering a breakdown. That will give you peace of mind, one of the best rewards.
