About Harmonic Heating & Air Conditioning

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

Old School HVAC Service

Fifty years ago customer service meant something completely different than it does today.

No one had to say “we provide superior customer service” because most everyone already did, from the smaller family run businesses and even large scale service businesses.

Back then your promise was your word, and you never had to question whether someone would follow through and deliver. People took pride in their work and had real relationships with their customers. They were friends, neighbors and family. Today common sense isn’t so common, and neither is customer service.

  • Harmonic Heating & Air Conditioning was founded with old school classic values in mind, like...
  • Honesty and integrity
  • Upfront and fair pricing
  • Punctuality
  • Empathy
  • Standing behind your work
