Spring AC Maintenance Checklist for Homeowners
lennox
A simple checklist before peak heat: filters, outdoor unit clearance, and when to call for a professional tune-up.
What you can do
Change or clean filters on schedule, keep the outdoor unit clear of grass and debris, and make sure supply vents are open and unblocked by furniture. Manufacturer owner guidance (including Lennox residential maintenance tips) commonly recommends monthly attention for typical one-inch filters in hard-use homes.
What a pro should check
Coils, electrical connections, refrigerant circuit integrity, drain lines, and overall airflow need trained eyes—especially after a mild winter when systems sit under-used then face full summer load.
Maintenance plans
A Cooling Experts maintenance plan helps you stay on schedule with priority service when available. Ask about Essential, Preferred, and Complete Comfort tiers—or book free maintenance with membership when that special is open.
