As summer approaches in North Alabama, homeowners in Huntsville, Decatur, and the surrounding areas know just how hot and humid things can get. If your HVAC system isn’t fully prepared, you could be looking at high energy bills, uncomfortable indoor temperatures, or even costly breakdowns during peak heat.

To help you stay cool and efficient this summer, the team at Clifford’s HVAC has put together a comprehensive checklist to ensure your HVAC system is ready for the season.

✅ 1. Replace or Clean Air Filters

Your HVAC filter is the first line of defense against dust, pollen, and pet dander—especially important in allergy-prone areas like Madison and Athens. A clogged filter reduces airflow, forcing your system to work harder and less efficiently.
Tip: Replace your filter every 30–60 days during peak usage.

✅ 2. Clear Debris Around Your Outdoor Unit

Check the area around your condenser unit (the big metal box outside). Leaves, weeds, and debris can block airflow and reduce cooling performance.
Tip: Keep a 2–3 foot radius clear for optimal airflow.

✅ 3. Test the Thermostat

Your thermostat is the control center for your entire HVAC system. Make sure it’s working correctly and reading the temperature accurately.
Upgrade Tip: Consider installing a smart thermostat—especially useful for homes in Huntsville with fluctuating schedules or remote control needs.

✅ 4. Check Air Vents and Registers

Walk through your home and make sure all vents and registers are open and unobstructed. Furniture, rugs, or closed vents can disrupt airflow and cause uneven cooling.

✅ 5. Schedule a Professional HVAC Tune-Up

An HVAC technician can inspect your system’s components, refrigerant levels, electrical connections, and overall performance to catch small issues before they become big problems.

✅ 6. Inspect Insulation and Attic Ventilation

Proper attic insulation and ventilation help keep cool air inside your home and reduce the strain on your AC system. If your attic feels like a sauna, your HVAC unit is likely working overtime.

✅ 7. Seal Leaky Ductwork

Up to 30% of conditioned air can be lost through leaks in your ducts. If certain rooms in your home aren’t cooling properly or you notice an increase in dust, it might be time to have your ducts inspected and sealed.

✅ 8. Listen for Unusual Noises

Grinding, squealing, or banging sounds from your HVAC unit are signs that something may be wrong. Don’t ignore them—catching issues early can prevent costly repairs.
