    Customer Testimonial

              I appreciate all your patience and understanding through this “hot” time for me. I get so stressed when something is broken that I cannot fix myself and I have to rely on someone else. But, you handled everything GREAT and even calmed me down and made me laugh. The work the guys did in the attic looks wonderful and very professional, kudos to them as well.

              Thanks for the follow up on the install, the guys did a great job on the install and were very professional in their work. I’m going to give you a call back around early spring to see about having the other system changed out as well.

    Jim D. of Dallas, TX

    Customer Testimonial

              Just wanted to take a moment to let you know what a fantastic job I received with my recent A/C repair. I have an older system where the lower A/C unit was not working during a extreme hot period here in Carrollton. The technician’s that serviced the equipment were professional and knowledgeable in regards to the repair. I have had many different service companies over the past (20) years coming out to the house for A/C problems and your company, by far, has been the best. I have had companies in the past that I felt were taking advantage of both the home warranty (AHS) and myself in regards to fixing items, for example always trying to sell more products than I needed. Although I am far from an expert on this stuff but do know enough to know when I am being taken advantage of. Again the technicians were excellent, the office support staff kept me up to date with the parts ordered and I appreciated that. Great job and I would highly recommend your company to anyone with A/C problems. Please pass on this information to the technicians and office staff as we tend to not bother communicating with excellent service which we should do more often!

    Rob of Plano, TX

    Customer Testimonial

              My experience with Kozy Services has been very positive. I recently had to have an old condenser and evaporator coil replaced. The service technician who initially looked at my problem and the three others who came to do the installation were knowledgeable, efficient, and friendly. There was a minor misunderstanding involving an unreturned phone call, but the owners responded to my complaint by going out of their way to schedule the installation service immediately even though it was on a weekend. One of the owners even called me from home over the weekend to answer a question I had. This family owned and operated business gave me the impression that they sincerely cared about how I felt as a customer. They came recommended by a friend, and I would recommend them as well.

    Karen of Plano, TX

    Customer Testimonial

              My furnace decided to quit on Sunday morning, I called my home warranty company (AHS) and they sent Kozy Services to my home. My past experience with contractors was horrible, I was very surprised by the professionalism that Julio the repairman showed me. He answered any question I asked him and he repaired my furnace on the same visit which NEVER happens with other contractors I've dealt with. If you need a great company, then call Kozy Services and request Julio. Customer for life!

    Customer Testimonial

              I was very pleased with the service I received from Kozy. The tech was very courteous and the thing that amazed me most was rather than try to upsell services, he actually saved me $200. This is the first AC company I've dealt with where I felt comfortable with the tech and didn't feel like he was there to make an extra buck. I'll definitely use them again in the future and will recommend them to family and friends.

    Tim of Grand Prairie, TX

    Customer Testimonial

              My wife and I are always looking for ways to save money and we discovered how getting attic insulation would help to reduce our electric bill. We looked around for attic insulation installers in our area and found Kozy Services. This company had great ratings with the BBB so we had them come out and do the estimate, and it was a good price for the work they'd have to do. Their techs were really nice guys and they not only did a great job, but they cleaned up really well after they were done with the installation. We will use Kozy Services again!
