Marc came out last week to give us a quote and came back today to install the whole house fan. We had another quote which informed us we needed 2 fans and was, of course, much higher. Went with Marc (only one fan needed) and we’re really happy with the results. Installation went smoothly and quickly. Fan is very quiet (we got the Quiet Cool Stealth model with a 3 speed motor and 570cfm). Highly recommended. Thanks Marc!
