Keep Your System Running Strong
A simple checklist of DIY tasks and seasonal adjustments — plus what to leave to a certified ArcticPro technician.
Monthly & Quarterly DIY Maintenance
Replace air filters: Swap out 1-inch filters every 30 to 90 days to prevent restricted airflow and freezing coils.
Clear outdoor debris: Remove leaves, twigs, and grass clippings from your exterior condenser unit to prevent overheating.
Maintain landscaping clearance: Trim shrubs and weeds to keep at least 18 to 24 inches of open space around the outdoor unit.
Keep indoor vents clear: Ensure furniture, rugs, and drapes do not block supply or return registers.
Unblock all registers: Do not close vents in unused rooms, as this disrupts balanced system pressure and strains the blower.
Inspect the condensate line: Look for standing water or leaks in the drain pan to ensure moisture is draining properly.
Flush the drain line: Pour a cup of vinegar or a diluted bleach solution down the AC drain line to prevent algae clogs.
