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!
