I recently worked with Malek Heating and Air because one of our rooms was not receiving enough air supply. The company installed a new duct and it seems like the installation went okay. However, there still isn't enough air in the room and there hasn't been a discernible difference after the service was completed, so I was kind of disappointed with the overall results. I appreciate that these guys gave us the lowest estimate of the companies that I contacted, and they were still very nice and friendly.
