Official Heating & Cooling was founded in 1986. Our endeavor is to better serve our customers. We have made several acquisitions over the last 2 years to increase our customer base and be able to service a larger area. In 2013, we acquired ACME Heating, a 65-year-old company located in Wheeling. They serviced the north shore and northwest suburbs. In 2014, we acquired Biewer Heating and Air Conditioning Co., a 35-year-old company out of Elgin. Chicago Magazine rated Biewer as one of the top HVAC companies in the Chicago area. In 2015, we acquired Active Air Plus. A 15-year-old company located in Palatine. These unions have been very well received and the expanded service area offers numerous benefits to the entire service area. In 2022, Official HVAC was acquired by Harmonic HVAC
