Our History Leader In Home Comfort Since 1931

In 90+ years, United Air Temp has evolved into a regional firm that serves the South East United States with over 30 branch offices and more than 300 technicians and staff.

United Air Temp’s history isn’t what one would expect from such a large firm. It began humbly in Erie, Pa. in 1931 as Fowler Heating Company, which manufactured incinerator equipment, and Aire Flow Distributing. By 1950, Fowler Heating Company Conjoined the manufacturing arm of the company and Heating & Air Conditioning partners to focus on HVAC needs to the consumer.

What Our Clients Are Saying
testimonial_image The tech was at my home less than 10 minutes and gone within 20 minutes due to having my A/C up and running. I really appreciate his response to my home and working with my son due to me being out of town, but we spoke on the phone.
testimonial_image The technician arrived promptly, wore a mask, was very courteous and professional. I am generally very satisfied with service by United Air Temp. In addition to good service (they repair well), it is easy to speak to a person, and promptly. Thank you.
testimonial_image Great service! I called because I was under the impression the AC was not working upstairs. Someone came on the same day, checked out the system, and ensured everything was working. He was polite, thorough, and friendly.
testimonial_image Tech was very attentive and professional. He went out his way to explain everything to me as he was doing it. I appreciated him keeping me informed.
testimonial_image The service technician was awesome! He spent the extra time necessary to ensure the leak in our system was fixed, the system fully recharged and everything was functioning as it should. He was extremely thorough and very professional. We are extremely pleased with the result!
