A friend recommended Raven for air conditioner installation. I got estimates from Raven and three other AC contractors and could not find anyone to beat their price. Dave (the owner) and his crew installed the system quickly and efficiently and with a great attitude. Dave was on hand throughout to answer all questions and make it a smooth experience that went without a hiccup. We have had a few days now to enjoy relief from the afternoon Novato heat and can report we are happy with the system.
