Our HVAC system quit. Lightfoot was super prompt in arriving & diagnosing our problem, and giving us our options for repair/replacement with a cost comparison for each. They knowledgeably answered all our questions. We made the decision to replace our unit. The techs arrived on time for the installation. Again, answered all our questions during the process. They showed us photos of the final attic installation & explained basic maintenance/operation for this unit. We are very pleased with Lightfoot Mechanical.
