About Us

CME is a family owned and operated full service HVAC (Heating, Ventilation, and Air Conditioning) company serving most of Southern California. Patrick Hilt, President of CME, has been in the Air Conditioning and Heating business since the 1950s and has over 50 years of experience. Mr. Hilt operated “The Harrison Company” for over 20 years, prior to selling the company in 1991. CME originated as the Orange County Branch of The Harrison Company in 1970 and has since become a separate and independent company.

CME has been specializing in air conditioning and heating service and maintenance for commercial customers throughout all of Southern California for almost 50 years. We have competitive pricing, and have focused our efforts towards commercial buildings and enclosed shopping centers. We have equipped our technicians with the latest in online technology to better serve our customers. While in the field, our technicians have instant access to service history and HVAC knowledge at their fingertips. We strive to provide our customers with quality work and customer service.

We are using UV Light technology to clean indoor air, prolong efficiency and aid in keeping out debris and living bacteria from evaporator coils and drain pans. UV Light also reduces the need for evaporator coil cleaning, which reduces maintenance costs.

We are currently testing energy saving products to help reduce unit electrical usage.
