Loescher Heating & Air Conditioning remains the leading source for design or build projects ranging from new schools to retail centers to giant warehouses and every project in between. We serve our clients with complete AUTOCAD/BIM capabilities and professional engineering stamps from Illinois, Iowa, and Wisconsin. Loescher is a Female Business Enterprise (FBE) with Certification by the State of Illinois and The Capital Development Board.

Building air ducts get dirty over time. Dirty air ducts can affect indoor air quality - subjecting building occupants to exposure to chemicals, molds, dust mites, bacteria, and other pollutants. Many indoor air problems can be traced directly to the HVAC system. Cleaning ductwork professionally can enhance the quality of air in your facility and save money on energy bills by improving the efficiency of your heating and air conditioning system. Loescher professionals remove dust, dirt, mold and debris in your air ducts using a quick, clean process that dislodges the fragments and powerfully vacuums harmful contaminants away.

For over 50 years, Loescher has served homeowners with the region's most efficient, reliable, personalized home comfort systems. We service all makes and models of furnaces, air conditioners, and boilers. We pride ourselves on providing efficient and effective service to protect and maintain your investments. We're proud of our factory-trained service technicians and our customer-focused sales team. Our Service Department operates 24 hours a day - 7 days a week. Complete energy efficient systems custom designed for your residence and lifestyle.
