Florida Is Not Like Everywhere Else
Most HVAC advice you find online is written with a four-season climate in mind. Change your filter every 90 days. Get your system serviced once a year. Maybe twice if you want to be thorough.
That guidance is fine for someone in Ohio. It does not really apply here.
In Central Florida, your AC runs. A lot. We are talking about a cooling season that starts in March, peaks through the brutal stretch from June to September, and does not fully let up until November. In a typical year, a Central Florida home might log 2,500 to 3,000 hours of AC runtime. In northern states, that number might be 800 or 900. The wear and tear is simply not comparable.
So the question of how often should your AC be serviced in Central Florida deserves a more specific answer than the general advice you will find on most websites.
The Baseline: Twice a Year, Minimum
For most Central Florida homeowners, two professional service visits per year is the right starting point. Not because some arbitrary schedule says so, but because of how our seasons actually work.
The first visit should happen in late winter or early spring, ideally between February and April. This is your pre-season tune-up. Your system has been running intermittently through the mild winter months, and you want to make sure everything is in solid shape before the relentless summer heat arrives. Discovering a problem in April is a very different situation than discovering it in July when every HVAC company in Central Florida is slammed with emergency calls.
The second visit should fall in the fall, somewhere in October or November. At that point, your system has just survived its hardest stretch of the year. A post-season checkup catches any wear that accumulated during the summer and gets your system ready for the lighter-duty heating months ahead.
Two visits a year is what we recommend as the baseline for homes with systems in reasonable shape. But depending on your specific situation, you might need more.
When You Should Consider Quarterly Service
Not every home and every system has the same needs. Here are situations where we typically recommend more frequent service.
Older systems. A unit that is ten or more years old has more components that are subject to wear and failure. Catching small issues early gets more important the older the system gets. Annual filter replacements and coil cleanings keep an older unit running reliably longer than it otherwise would.
Homes with pets. Pet dander and fur move through your HVAC system constantly. Filters clog faster, and coils can accumulate buildup more quickly. We see this on almost every call to a home with multiple animals.
Allergy sufferers or households with respiratory concerns. If anyone in your home has asthma, allergies, or other respiratory conditions, you want your system operating cleanly. More frequent filter changes and coil inspections help maintain indoor air quality.
Homes with heavy use or large square footage. More square footage means more runtime. More runtime means more wear. The math is straightforward.
For households in any of these categories, quarterly filter checks and at least two professional visits are a reasonable expectation. Some of our customers on maintenance agreements see us three times a year, and it makes a measurable difference in their system reliability.
What a Real Service Visit Should Include
This matters because not all tune-ups are created equal. A technician who shows up, changes your filter, glances at the unit, and leaves in 25 minutes did not do a real service.
A proper AC service visit should cover the following areas at minimum. Checking refrigerant levels and inspecting for leaks. Cleaning the evaporator and condenser coils. Testing the capacitors and contactors, which are electrical components that fail regularly and cause sudden system shutdowns. Measuring airflow. Inspecting the condensate drain line, which in Florida’s humidity can clog quickly and cause water damage. Testing the thermostat calibration. Checking all electrical connections.
The Air Conditioning Contractors of America publishes standards for what a residential maintenance visit should cover if you want to get a sense of the full scope. We follow those guidelines on every visit.

Between Service Visits: What You Can Do
Professional service is not the whole picture. There are things you can do between visits that genuinely extend the life of your system and reduce the chance of a breakdown.
Change your air filter regularly. In Central Florida, every 30 to 60 days is more realistic than the 90-day recommendation you see on packaging. During heavy-use summer months, lean toward the shorter end. Keep the area around your outdoor condenser unit clear. Plants and shrubs grow fast in Florida, and a unit surrounded by overgrown vegetation cannot breathe properly. Make sure your condensate drain line stays clear. A simple cup of diluted bleach poured into the drain access point every few months can prevent algae buildup that causes blockages.
None of that replaces a professional visit. But it absolutely reduces how much work your technician finds waiting for them when they do show up.
The Real Cost of Skipping Service
I want to be honest about something. Skipping service visits feels like saving money. I understand the logic. If nothing is broken, why spend the money?
But here is what we see consistently in the field. Systems that go two or three years without professional service tend to fail during heat waves. Compressors burn out. Capacitors fail. Coils freeze because nobody noticed the filter was overdue. And those repairs cost far more than a maintenance visit would have.
According to Energy Star, a well-maintained AC system uses significantly less energy than a neglected one. The monthly savings on your electric bill alone can offset the cost of regular service over time. Florida Power & Light customers know how fast a bill can climb in July.
Regular maintenance is not a luxury. In Central Florida’s climate, it is just what responsible homeownership looks like.
Keeping Your System Ready for Summer
The short answer to how often your AC should be serviced in Central Florida: at least twice a year, with filter changes every one to two months in between. More if your system is older or your household has specific needs.
If you are not sure when your system was last professionally serviced, that is worth knowing. Simply reach out to us at All Star Heating & Cooling and we can get a tech scheduled to take a look. We serve all of Central Florida, and we would rather catch a small problem in spring than meet you during a breakdown in August.
