"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

"The first person came to do this job but left many pieces out of the installation. He did such a poor job of mounting the 55" TV that it began leaning lopsided! Gilbert came to undo all the first person messed up. Gilbert assembled and mounted my 55 inch TV on a large stand that he had to put together again correctly after taking down the awful job done by Diego. Gilbert had no problem with the complex instructions and did a fine job even going out to get screws that had been inserted incorrectly. Gilbert was professional and worked quickly. I would use him again without hesitation."

"Everything went fine with the exception of the fan install which was pretty tricky - we have some funky wiring done in the 80s by the old homeowner. Otherwise, great - Marcus got out to our house quickly and there were A LOT of lights/switches/exhaust fans to install which were taken care of quickly and at a reasonable price."

"Overall it went smoothly without major hitches. There we some delays in getting the windows delivered but that was not on the company. I also did not negotiate to paint the exterior window frames which would have been easy to do at the time of installation. Because it is a second story unit I had to pay someone to do this after the windows were installed. But besides that it was a good experience and was done without issues and it was on time. Their price was competitive. The folks who did the work and the estimates were friendly and professional and the quality of work was excellent."

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.

There are many types of ceiling fans available, each designed for different spaces and needs. Standard ceiling fans are the most common type and work well in most rooms. Low-profile ceiling fans are better suited for rooms with low ceilings. Smart ceiling fans can be controlled with a smartphone or voice commands. For larger spaces with ceilings between 10 and 25 feet high, large ceiling fans are ideal. Dual-motor fans have two motors to produce more airflow in multiple directions. You can also find energy-efficient or Energy-Star models that can be up to 60% more efficient, as well as fans with built-in lights or retractable blades.

While wood stove fans are effective for improving heat distribution, they rely on the stove reaching a certain temperature to operate efficiently. If the stove does not generate enough heat, the fan may not start or may not move air effectively. Additionally, like any fan, wood stove fans cannot cool a stove or reduce its heat output—they only redistribute existing warmth.

Selection relies on matching fan size and power to attic volume and ensuring compatibility with home electrical systems and ventilation requirements.

The number of blades for your fan poses both advantages and disadvantages. Typically, the more blades on a fan, the better the air distribution and cooling effect, but this also means that your fan will have more wear on its motor. For small rooms, three-blade fans should work fine. For larger areas like living rooms, four or five-blade fans might be the better option.
