It is possible to fix your bath fan without replacing the entire unit and improve air flow with a first class vent system. You can replace a dead motor without tearing out the ceiling and replacing the whole thing. You can also improve venting and prevent roof rot by running the vent through the roof, and not leave it in the attic as was done by many contractors. There are many options when it comes to fixing a vent fan, which means many options for pricing.
Motor Replacement
Even if you fan is decades old, chances are you can get a replacement motor. Although a new motor costs about the same as a new fan, simply replacing the motor saves time, money and trouble. Your professional won't need to cut into the ceiling (thus adding expense of repairing ceiling), crawl around your attic or get up on your roof. It usually takes a professional less than an hour.Adding a New Duct
Many times, when there's an attic above the bathroom, some installers may have taken a shortcut when they built your home: Instead of running the duct through the roof, they end the duct inside the attic. The result is that the fan fills the attic with moist air and that moisture can cause your wood to rot. In winter, frost forms in the attic and as the frost melts, water can damage the ceilings below. You may notice this as a ring on your ceiling. Running a new duct up through the roof isn't a complex job, but your professional electrician will have to work in the attic and on the roof.Bath Fan Repairs Cost Calcualtor

Lighting Repair
Many bath fans also include lighting as a part of their structure. Based on the type of lighting in your fan, it can run you from just a few dollars to even a couple hundred dollars to fix. If there has been condensation within the electrical components, you may need more work done in order to get the lighting to work properly again.Duct and Vent Cleaning
Indoor air quality can have a major impact on your health and comfort. Over time the air ducts in a home build up with dust, debris and even mold. Removing these contaminants provides your home with cleaner air and can make your systems run more efficiently. The time and cost it takes for a professional duct-cleaning service to clean your ducts and vents can vary.Typically, the entire process takes 4 to 5 hours and you can expect to spend $50 to $150 an hour. But if you take into consideration how much money you might waste on dirty, leaky ducts and on any associated medical expenses, this upfront investment might be well worth the cost. Likewise, your local utility company might issue an energy rebate for maintaining your home ducts and vents.
