Most maintenance advice online is written for a climate with a short cooling season. In Tallahassee, an air conditioner may run in some capacity from March through November, which changes both how often service is worthwhile and what that service should focus on.
The short answer: twice a year
Service the cooling side in spring, before the load arrives, and the heating side in fall. Two visits a year is the standard that makes sense for equipment running the hours Florida equipment runs.
If budget only allows one visit, make it the spring cooling check. Our cooling season is long and demanding, and cooling failures are the ones that make a house genuinely unlivable.
Why Florida is different
- Run hours: a local system can accumulate in one year what a northern system accumulates in two.
- Humidity: condensate production is enormous, and drain lines clog with biological growth far faster here.
- Pollen: spring coats outdoor coils and loads up filters within weeks.
- Storms: summer power events are hard on capacitors, contactors, and control boards.
- Heat: an outdoor unit working in 95-degree ambient temperatures has far less margin for a dirty coil.
What a worthwhile maintenance visit covers
- Clearing and treating the condensate drain, and verifying the safety switch works.
- Inspecting and cleaning coils as needed.
- Measuring refrigerant pressures and temperatures to catch a developing leak.
- Testing capacitors against rated values rather than just eyeballing them.
- Checking amp draw on the compressor and motors.
- Reviewing airflow, filter condition, and return sizing.
- Verifying thermostat operation and heat mode, including strip heat or reversing valve function.
What you handle between visits
Filters are the homeowner's job and the single highest-value habit. In pollen season, or in homes with pets, a one-inch filter often needs attention every month regardless of what the packaging says.
Keep the outdoor unit clear of pine straw and vegetation, rinse the coil gently with a hose when it looks dirty, and pay attention to any new noise or change in how long the system runs.
Is a maintenance plan worth it?
The value of a plan is mostly that the visits actually happen. The maintenance itself is what protects the equipment; the plan is a scheduling mechanism. If you will reliably book service twice a year on your own, that works just as well.
Frequently asked questions
- Can I skip maintenance on a new system?
- Manufacturers commonly require documented maintenance to keep warranty coverage intact, and new equipment is just as vulnerable to a clogged drain as old equipment. Do not skip it.
- When is the best time to schedule spring service?
- Late winter through early spring, before the first stretch of hot weather. Once the season starts, schedules fill with no-cooling calls.
