The main job is checking your air filter at least monthly and replacing it when dirty. This keeps your system efficient. Beyond that, certified technicians handle routine checks during maintenance visits-and most warranties require annual service by a certified contractor or they become void. Neglecting maintenance can cost you warranty coverage. Learn more about Bud's Maintenance Plan to keep your new system running like new for years.
