What Our Customers Have to Say About Interstate

  • “The call I made to Interstate Heat & Air was with an E-Mail about 11 P.M.
    on February 3rd 2014. On February 4th 2014 I received a phone call from Interstate H/A. They set an appointment for the 5th at 8 am. The Heat & Air Service technician put on shoe coverings before he entered. The first thing he introduced himself and who he represented. Willie Hester with Interstate Heating and Air. Mr. Hester took his tool kit to the H/A unit removed the panel and began to check the condition of the unit. Mr. Hester explained each test as it was done. My reason for this service call was the heating unit just stopped and did not come on for more than an hour. The unit was in good condition but did have a bit of a scorched area on the motherboard. Mr. Hester replaced the filter, which was real dirty and replaced the panel. The cost was $158.00. I know that quality does cost and if you want the best quality call Interstate H/A in OKC. Mr. Hester said Interstate H/A offered a yearly service club maintenance program and it was very low cost. The Wife and I were relieved to know that program would save us from worry about getting quality service anytime. We thank Interstate Heat and Air and Mr. Willie Hester. Thanks, Darrell and Lynda McDevitt.”
