I’ve been using LBA for years because their service is great. I switched briefly to someone else several years ago that a family member suggested for a new furnace and regretted it. They just couldn’t compare to the responsive service I get with LBA. Honestly they are probably not the cheapest but I feel I’m paying for the responsiveness I get with them especially if I were to have an emergent need. Over the years the technicians that have been in my home seem caring and honest which I appreciate. Thanks!
