    “Since 1978.”

    Those two words may not mean much to you, but to those of us at One Hour Heating & Air Conditioning, they mean everything. That’s because 1978 is the year it all began for our heating and cooling company… and continues to this day in the very same spirit in which it started.

    Heating and cooling is and always has been our family business. And a family business means that we operate the business with care and concern and understanding for those who work with us and especially those who we work for…. our customers.

    From the days of S&K Heating & Air Conditioning in 1978 to the current name of One Hour, the common denominator has been the Stewart family. From Ray to Steve to Matthew, we continue to practice the same family values in our business that have blessed our family for decades.

    Our promise to you, our customers, is that you will always receive the highest level of professional service and peace of mind with clean, well-trained, background-checked and drug-tested technicians working in your home. And friendly, courteous care staff who actually listen and respond to your needs.

    We maintain, service, and install all residential heating and air conditioning equipment and offer 24/7 emergency service.

    We thank you for allowing us to serve you and we look forward to continuing to live up to our family promise each and every day.
