    Glenn has been such a gift to us. He installed a brand new a/c unit a few years ago and it’s top quality. Best we’ve had as a 35 year homeowner. Our electric bill was cut in half. He improved our exchanges for a better flow and it’s made a huge difference. We wouldn’t even have known to do it. His work ethic is old school; comes early and stays late. Gives it all he has always. We totally trust him which is a hard thing to find these days. We have him out twice a year to make sure our HVAC is working properly. He EVEN answered our texts on a holiday weekend AND came by that Monday. We always feel safe and sound after he leaves. That’s a great blessing. I highly recommend Glenn!
