We love our pets, but they can affect more than just our furniture and floors. If you’re a pet owner in Pasadena, your HVAC system plays a major role in maintaining good indoor air quality (IAQ). From fur and dander to pet-related odors, here’s what you need to know about keeping your air clean and your system running smoothly.
How Pets Impact Air Quality
Pets shed fur and skin cells (known as dander) that circulate throughout your home. These particles can:
- Clog HVAC filters more quickly
- Accumulate in ducts and vents
- Trigger allergies and asthma symptoms
- Lead to increased dust and odors

If you have multiple pets or high-shedding breeds, the effects on your HVAC system and indoor air quality can be even more significant.
What You Can Do to Improve IAQ with Pets
Fortunately, your HVAC system can help manage pet-related air quality issues if it’s properly maintained and equipped.
1. Change Your Filters More Often
Pet dander and fur clog filters fast. If you normally change your filter every 90 days, switch to every 30–60 days with pets. Consider using HEPA-rated or high-MERV filters to trap smaller particles.
2. Schedule Regular HVAC Maintenance
Routine tune-ups help remove built-up debris and ensure your system is circulating clean air. Technicians can also check for fur or pet hair buildup in blowers and ducts.
3. Clean Vents and Ducts
Over time, pet hair can accumulate inside your ductwork. A professional duct cleaning every few years (more often for multi-pet homes) helps remove allergens and odors.
4. Use an Air Purifier or IAQ Upgrade
Installing an in-duct air purifier or UV light system can improve air quality and help neutralize pet odors and allergens. Ask your HVAC provider about options that integrate with your existing system.
Other Simple Tips for Pet Owners

- Bathe and groom your pets regularly to reduce shedding.
- Vacuum floors, rugs, and upholstery often.
- Keep pets out of mechanical rooms or near HVAC return vents.
- Consider washable filters if you’re changing them frequently.
