Tips for Thornhill homeowners to maintain AC performance between visits

Small, regular actions reduce breakdown risk and lower operating costs:

• Change or clean filters every 1 to 3 months depending on usage and indoor air quality.
• Keep the outdoor unit clear of leaves, debris, and overgrown plants to maintain airflow.
• Shade the condenser with landscaping or a screen without restricting airflow to improve efficiency.
• Run ceiling fans to raise comfort and allow thermostat settings a few degrees higher.
• During wildfire season, upgrade to high-MERV or HEPA-compatible filters and consider a portable or whole-home air cleaner.
• Check and clear the condensate drain line in spring to prevent backups and mold.
• Seal and insulate ductwork in unconditioned spaces to prevent energy loss.
• Schedule professional maintenance before the cooling season and again if the system shows reduced performance.

Because Thornhill experiences humid springs and occasional smoky summers, homeowners should consider a system check in late spring to ensure dehumidification and filtration are functioning before peak demand.
