Pet Hair Impact

Pet hair accumulates on the indoor unit filter faster than dust alone. In homes with pets, filters may need cleaning every 1-2 weeks instead of monthly. Hair that bypasses a dirty filter collects on the indoor coil, reducing efficiency and potentially causing odours.

Filter Maintenance

Check the indoor unit filter weekly in homes with shedding pets. Clean with warm water and let dry completely before reinstalling. Use higher-quality filters or pre-filters if available for your mini-split model. Groom pets frequently to reduce loose fur in the home.

Professional Cleaning

Schedule professional coil cleaning annually for homes with pets — the indoor blower wheel and evaporator coil need specialized cleaning that DIY cannot achieve. Professional cleaning costs $150-250 and restores 10-20% efficiency lost to pet hair buildup.

Safety Reminder

If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
