Preventive Maintenance (PM) Basics

Change Your Air Filter Regularly

• Swap your filter every 1–3 months.
• A clean filter improves airflow, lowers bills, and helps your system last longer.

Keep Vents & Registers Clear

• Don’t block vents with furniture or rugs.
• Vacuum grilles to reduce dust buildup.

Check Your Thermostat

• Replace batteries once a year.
• Upgrade to a programmable or smart thermostat for better comfort and savings.

Maintain the Outdoor Unit

• Clear away leaves and debris around your condenser.
• Gently hose down coils twice a year to keep them clean.

Keep the Drain Line Clear

• Pour a cup of vinegar into the condensate drain every few months.
• This helps prevent algae clogs and leaks.

Schedule Professional Service

• Have HRI Mechanical inspect your system annually.
• We’ll check refrigerant, safety controls, clean coils, and tune your system for peak performance.

Troubleshooting Common Problems
