Why Our Customers Love Us

In business since 2002, Interstate is a company built from the ground up. We owe our loyal customers for our success today and place great importance on keeping our promises. A real person will answer the phone when you call and someone will be available to solve your comfort problems at all times, even during evenings and weekends, and we never charge overtime fees.

From start to finish, our work is not complete until you are completely satisfied—we guarantee it! From the moment we arrive at your home, our technicians will be prompt and professional. They will arrive on time and always have a courteous manner. Our technicians put down tarps to protect your flooring, and wear booties over their work boots to never leave a mess. We promise to leave your home as clean, or cleaner than when we came in.

Our customers choose Interstate because we offer:

  • Convenient on-line booking.
  • Drug-free, background checked, professionally licensed technicians.
  • Maintenance plans that save you money all year.
  • Quality workmanship.

We Know Our Stuff

We know HVAC. Regardless of the brand, we can install it, fix it and maintain it. Most other HVAC companies will only specialize in one brand of heating and cooling system. This is not the case at Interstate. We sell and service a wide array of makes and models. Therefore, we can recommend what’s right for you and your home, both in style and affordability. Plus, we provide free estimates on your HVAC installation so you know the cost before we do the work.

We pride ourselves on outstanding customer service and creating an all-around pleasant experience for our clients. With same-day 24/7 service, no overtime charges and zero hassle, Interstate is the go-to source for HVAC services in Oklahoma City and the surrounding area.

Our Interstate Insurance: if you’re not 100% satisfied, you don’t pay a dime.
