AC units are the hardest working appliances in Florida homes and businesses. With regular maintenance, the expected AC unit lifespan in Florida is 10-15 years.

We’ve put together a list of determining factors in the life expectancy of a Floridian AC system and when it’s time to think about replacement. 

What Determines the Average AC Unit Lifespan in Sanibel Island, Florida? 

Location

HVAC units in the Sunshine State are the number one consumers of energy in households and businesses and can be expected to last about 5-7 years less than other states. The high heat and humidity take a huge toll on HVAC systems and not to mention the frequent storms, the hurricanes and being surrounded by seawater.   

Heat & Humidity 

Heat and humidity can wreak havoc on an AC unit. Not only does the Florida heat have your unit working overtime, but the humidity can create mold and mildew in ductwork and corrode parts of your AC system. 

Weather 

An exterior HVAC system is susceptible to the elements. Not only can rainstorms corrode components but severe storms, such as hurricanes, have strong winds with flying objects and debris that can potentially damage your unit.   

Living by the Coast

Due to the salty air on Sanibel Island, the rate of corrosion because of its current-carrying ability is greater than from freshwater. 

Maintenance

Preventative maintenance is also something that will increase AC unit lifespan. Scheduling a routine maintenance visit from a fully licensed technician should be done every six months in the state of Florida.

Air filters should also be replaced every 30-45 days due to moisture, dust, mold and other allergens.   

AC Unit Quality

The lifespan of your AC system also depends on the quality of parts and in this situation, you get what you pay for. You’ll want a system from reputable manufacturers with solid warranties.   

If your AC unit has a higher SEER rating, or Seasonal Energy Efficiency Ratio, your system will be more energy-efficient and more effective at keeping it cool. The minimum SEER rating for air conditioners is 13 and most range from 13 to 21.   

How Will I Know When It’s Almost Time to Replace My System? 

There are several signs that your HVAC unit is in need of repair or on its last leg: 

• Age: If your unit is over a decade old and experiencing some of the issues listed below. 
• Energy usage: High energy bills are a sign that it may not be as efficient as it once was. Declining efficiency usually happens with age.   
• Unusual smells: It may be nothing to worry about but a different smell could indicate a problem such as an electrical or mechanical issue. 
• Strange sounds: After years of constant use, parts and bolts come loose. This is usually an easy repair but noises such as grinding and squealing could be a mechanical problem.
