Exhaust Fan Replacement


Detailed Description
Replacing an exhaust fan may seem simple, but matching the existing size and venting can be challenging. At CNG Contracting, we make Exhaust Fan Replacement easy and stress-free, upgrading your system for better performance and silence.
Our process starts with assessing the current fan, duct diameter, and electrical connections. We help you choose the right replacement fan for efficiency (CFM) and noise reduction (Sones), ensuring it fits your space perfectly. Installation is carried out precisely, with attention to proper alignment and airtight connections to prevent leaks or vibrations. We focus on preventing moisture buildup that leads to mold, helping your Toronto & GTA home stay comfortable, safe, and well-maintained. On the day of service, we work efficiently and leave everything clean. Professional, reliable, and done right the first time.

Frequently Asked Questions
Can you make my bathroom fan quieter?
Yes. Old fans often rattle and hum. We install modern fans with low "Sone" ratings (under 1.0), which are virtually silent while moving more air than your old unit.
Do you install kitchen range hoods?
Yes. We install both under-cabinet and wall-mounted chimney range hoods, ensuring they are properly vented to the outside to remove grease and cooking odors.
Can you add a timer switch?
Absolutely. We highly recommend installing a digital timer or a humidity-sensing switch so the fan runs long enough to clear moisture after a shower, then shuts off automatically.
Why is a Technical Visit necessary?
Buying a fan off the shelf often leads to disappointment because the housing size doesn't match your ceiling cut-out, or the duct diameter (3" vs 4") is incompatible, causing back-pressure and noise. Furthermore, venting a bathroom fan directly into the attic instead of through the roof is a code violation that causes attic mold. Our Exhaust Fan Replacement assessment verifies the duct path, housing dimensions, and electrical load to ensure a safe, code-compliant installation.
