24/7 Emergency Service


A/C Service in Denver, CO

About 90% of cooling system malfunctions are caused by dust and dirt.  Even one millimeter of dirt on a cooling coil can reduce efficiency up to 21%.  While your air conditioner sits idle during the winter, it collects contaminants such as mold, fungi, bacteria, and dust, which negatively impacts performance, reliability, and air quality.  Studies completed by the Environmental Protection Agency have proven that regular HVAC cleaning allows systems to operate more efficiently.  An air conditioner running in peak condition is less likely to break down, will last longer, deliver superior comfort, keep sound levels to a minimum, and cost less to own and operate.  Call on L&L Heating & Air Conditioning at 720-851-1691 for conscientious air conditioner maintenance in Parker, Aurora, Centennial, Lone Tree, Highlands Ranch & Castle Rock, CO..
