Get Ready for the Heat: Your 2025 Summer HVAC Maintenance Checklist

Here’s what every facility manager should have on their radar before the peak of summer:

✅ Inspect and replace air filters

Dirty filters reduce airflow and increase energy use. For high-use systems, check monthly.

✅ Clean evaporator and condenser coils

Dirt buildup reduces efficiency and cooling capacity. Clean coils ensure faster heat transfer.

✅ Test thermostat accuracy and settings

Calibrated thermostats reduce wear and maintain occupant comfort.

✅ Clear debris from outdoor units

Leaves, dirt, and obstructions can cause overheating and airflow problems.

✅ Check refrigerant levels and inspect for leaks

Low refrigerant can damage compressors and reduce system performance.

✅ Inspect ductwork for leaks or insulation issues

Leaky ducts waste energy and affect zone performance.

✅ Lubricate moving parts and check belts

Friction and wear reduce efficiency and increase the risk of breakdowns.

✅ Verify electrical connections and control panels

Loose or corroded connections can cause system failure and safety hazards.

✅ Check for signs of microbial growth

Mold and bacteria in drain pans or ducts pose health risks and reduce IAQ.
