This is another A+ score for LBA. Calvin did the annual furnace checkup for us this past month so we were pleased when we saw he was returning after our recent service call when our furnace quit putting out heat during the night. Of course you always expect the worse but it turned out our furnace had quit working because the flue was blocked by a mud dauber nest which he discovered after a thorough investigation. He cleared the nest and then made sure everything was working with no problems. Calvin is a great asset to your team as are all your technicians who are thorough, professional and represent you well. We would definitely recommend LBA for your HVAC needs.
