No AC or Heat This Weekend?
Troubleshoot These 5 Common HVAC Issues Before Calling for Emergency Service
Nothing ruins a Florida weekend like an AC or heat pump breakdown. Before you panic (or sweat it out), try these quick troubleshooting steps—you might just save yourself a service call!
1. Check Your Thermostat First
One of the most overlooked HVAC issues is a simple thermostat setting.
✅ Ensure it’s set to the correct mode – “Cool” for AC or “Heat” for winter days.
✅ Adjust the temperature a few degrees to see if the system kicks on.
✅ Replace thermostat batteries if it’s not responding.
A faulty thermostat can mimic a system failure, so ruling this out early can save time!
2. Inspect Your Air Filter for Clogs
In Florida’s humid climate, dirty air filters restrict airflow and force your system to work harder, leading to shutdowns.
✅ Check the return filter—if it’s dusty or clogged, replace it immediately.
✅ Change filters every 30-60 days (or monthly if you have pets or allergies).
Pro tip: A dirty filter can cause frozen coils, poor airflow, and higher energy bills.
3. Check Your Circuit Breaker
Power surges and electrical fluctuations—common in Florida—can trip your HVAC breaker.
✅ Locate your electrical panel and check if the HVAC breaker is tripped.
✅ If it’s off, flip it back on and see if the system restarts.
⚠️ If it trips again, do NOT reset it repeatedly—this could indicate a serious electrical issue. Call a professional!
4. Ensure Returns & Supply Vents Are Open
Proper airflow is critical for HVAC performance.
✅ Make sure all return and supply vents are unblocked—furniture, rugs, or curtains can restrict airflow.
✅ A blocked return can cause poor cooling, short cycling, and even system failure.
If some rooms feel hotter than others, you might have ductwork issues or an airflow imbalance.
5. Listen for Strange Noises
Unusual sounds often signal HVAC trouble:
🚨 Buzzing? Electrical issues.
🚨 Hissing? Possible refrigerant leak.
🚨 Clicking but no startup? Likely a capacitor or compressor problem.
If your system is making loud or persistent noises, it’s best to call in a professional before it gets worse.
