Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

Bathroom Fan Installation questions, answered by experts

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Rigid ducts are easier to clean and can withstand any moisture the bathroom may create, but they are more costly and can’t be easily moved. Flex ducts are a great solution if you don’t have much space and want flexibility in where you place your duct, but they’re more difficult to clean, need a lot of support, and aren’t as sturdy as rigid ducts.

Regular cleaning, sealing ductwork, and ensuring proper airflow paths keep systems functioning optimally, maintaining energy efficiency.

Installation generally takes 2 to 4 hours, depending on the home structure, electrical characteristics, and attic access ease.

A bathroom fan lasts between five and ten years, depending on its quality, how it’s installed, and how often you use it. If you notice your fan is no longer working as well as it once did, consider replacing it before it stops working altogether. Installing a bathroom fan costs between $240 and $550.
