Preventive Maintenance:
- At least once per year (preferably before the heating season):
- Replace or clean air filters
- Inspect heat exchanger for corrosion or cracks
- Check blower motor and wheel for dust and performance
- Ensure venting and combustion air connections are clear and secure
- Review control board fault history
- Confirm proper airflow and temperature rise
Repair & Troubleshooting:

- Use only genuine Daikin parts and follow manufacturer service protocols to maintain efficiency and warranty coverage.
Frequently Asked Questions (FAQs)
Q: What does “single-stage gas valve” mean?
A: The furnace operates at full output whenever it is on. While it doesn’t modulate like two-stage models, its high-efficiency design (96% AFUE) still provides excellent comfort and performance.
Q: Why choose “Ultra-Low NOx”?
A: The “U” designation ensures the furnace meets very low nitrogen-oxide emissions (≤ 14 ng/J), ideal for Mississauga homes with environmental considerations or air-quality regulations.
Q: What advantages does the variable-speed ECM blower provide?
A: Delivers smoother, quieter airflow, better comfort, consistent indoor temperatures, improved humidity control, and energy savings.
Q: Is ~96% AFUE worth the cost difference?
A: Yes — nearly all fuel is converted into usable heat. Over time, especially in Ontario’s climate, the savings on heating costs can be significant.
Q: How often should the furnace be serviced to maintain warranty?
A: At least once a year. Homes with pets, heavy dust, or older ducts may benefit from more frequent maintenance to preserve efficiency and warranty coverage.
