I had a really positive experience with Bay Area Whole House Fans and recommend them highly. First, Mike the estimator was very thorough, knowledgeable, and answered all of my questions factually. He did a thorough assessment of my home and attic, including measuring its vent area and sizing the fan appropriately. He also determined and shared with me where to place the fan and how to wire it. The company quickly gave me a very reasonable quote and was able to schedule the installation only a couple weeks after the estimate. Brian and Andy did a very professional installation (see photo) and completed the work in only 2 hours including showing me how to use the fan and answering my questions. They left my house and driveway completely clean too. The dont have the fanciest vehicles but they have highly competent people who do great work at very reasonable cost.I had another local five star review A/C company give me a quote but it was much more expensive and that other companys estimator did not properly measure my attic vents and suggested a fan that would have been too small. Im very happy I went with Bay Area WHole house Fans instead!
