Living in Stuart, FL, means dealing with relentless heat and humidity almost year-round. And let’s be honest—your AC unit isn’t just a luxury; it’s a necessity. If your AC goes down in the middle of summer, you’re not just uncomfortable—you’re in survival mode. That’s why keeping your system in top shape is non-negotiable.
The good news? You don’t need to be an HVAC pro to extend the life of your unit and keep your home cool. A little routine maintenance goes a long way. Below are the best AC maintenance tips for Stuart, FL, residents straight from the experts at Air Plus, the #1 AC repair company in town.
1. Change Your Air Filters—Like, Religiously
Let’s start with the lowest-hanging fruit. Changing your air filters is the easiest, fastest, and most effective thing you can do to keep your AC running efficiently. A clogged filter chokes airflow, makes your unit work harder, and can even cause it to overheat.
How Often?
- Every 30-60 days for regular households
- Every 20-30 days if you have pets or allergies
- Every 60-90 days if your system rarely runs (not likely in Florida!)
Skipping this simple task can lead to higher energy bills and more frequent breakdowns. Set a reminder on your phone. No excuses.
2. Clean Your Outdoor Unit (Because Florida Weather is Brutal)
Your outdoor condenser unit is constantly exposed to the elements—rain, dirt, leaves, and even the occasional lizard. If the coils get clogged, your system won’t dissipate heat efficiently, leading to weak airflow and higher energy costs.
Quick Fix:
- Turn off the power to your AC unit.
- Use a garden hose (on a low setting) to rinse off dirt and debris.
- Trim any vegetation at least 2 feet around the unit to maintain proper airflow.
Do this every few months, especially after storms.
3. Check Your Thermostat Settings
Your thermostat is the brain of your AC system. If it’s outdated, improperly placed, or not calibrated correctly, your unit will run inefficiently. If you’re still using an old-school manual thermostat, it’s time to upgrade to a programmable or smart thermostat. These can reduce energy consumption by up to 10-15%.
Best Practices:
- Set your thermostat to 78°F when you’re home for optimal efficiency.
- Increase it to 82-85°F when you’re away to save on your energy bill.
- Avoid drastic temperature changes that make your AC work overtime.
4. Keep Your Ducts Clean—Or Pay the Price
Dirty ducts don’t just mess with your air quality; they also reduce your system’s efficiency. If your ducts are clogged with dust, mold, or debris, your AC has to work harder to push air through.
Signs You Need Duct Cleaning:
- You notice more dust than usual around your vents.
- Your allergies are acting up inside your home.
- There’s a musty or moldy smell when your AC runs.
Schedule professional duct cleaning every 3-5 years or more often if you notice issues.
5. Flush the Drain Line (Because Mold and Algae Love Florida)
Your AC removes humidity from the air, and that moisture has to go somewhere—down the drain line. If this line gets clogged, it can cause water leaks and even shut down your system.
Easy DIY Fix:
- Locate your AC’s drain line (usually a PVC pipe near the outdoor unit).
- Pour a cup of vinegar or a 50/50 mix of bleach and water down the pipe every month to prevent blockages.
If your drain line is already clogged, call the pros at Air Plus to avoid water damage.
6. Don’t Ignore Strange Noises or Smells
If your AC makes weird noises or gives off odd smells, don’t just hope it goes away. That’s like ignoring a check engine light and expecting your car to fix itself.
Common Red Flags:
- Grinding or squealing = Worn-out belts or motor issues.
- Banging or rattling = Loose parts or failing components.
- Burning smell = Electrical issues (turn off your unit immediately).
- Musty smell = Mold or mildew buildup (time to clean those ducts!).
If something seems off, call in the pros before a small issue turns into a full system failure.
7. Schedule Professional Maintenance (Because DIY Can Only Go So Far)
Even if you follow all the steps above, you still need a professional tune-up at least once a year. HVAC techs can catch problems before they become expensive repairs and keep your system running at peak efficiency.
What a Pro Will Do:
- Inspect and clean the evaporator and condenser coils
- Check refrigerant levels and look for leaks
- Test electrical connections and components
- Lubricate moving parts to prevent wear and tear
Think of this as an oil change for your AC—skip it, and you’re looking at bigger, costlier problems down the road.
8. Consider an AC Upgrade (If Yours is Over 10 Years Old)
Even with the best maintenance, AC units don’t last forever. If yours is 10-15 years old, inefficient, or constantly breaking down, it may be time to upgrade to a newer, energy-efficient model.
Benefits of a New AC:
- Lower energy bills (modern units use up to 40% less energy)
- Better cooling performance
- Quieter operation
- Smart features for better control and efficiency
