    “Timely and Professional”
    “Owner, Chad Sheffield recommended the American Standard brand for the replacement of my 13-year-old A/C & Heat system. The crew was on time, professional, and had my home cooling in half a day. Best of all, I am saving 35% less on electricity!”

    “Very Professional”
    “We called C.A.S air and heating and they came out not only the same day, but within a couple of hours. In minutes he had the problem diagnosed and had us back up and running. I cannot say enough about the professionalism of Chad. I would highly recommend!”

    “I had an urgent need for an HVAC specialist to come an assess an HVAC system on a home. He responded immediately. Very personable, thorough in his evaluation, and took time to answer my long list of questions. I would recommend him to anyone.”

    “Prompt and Thorough”
    Our AC went out on a Monday and people we have a warranty through couldn't get anyone out here till the next week. After hours of trying to get a work order to get someone else here, C.A.S. was recommended. Cody came out the next day cleaned connections and it started working. Would definitely recommend them.

    “Highly Recommend”
    I've used CAS twice. The first time our AC was frozen up and he had given me advice over the phone and told me what to do. He didn't expect anything in return. I called him anyway and asked him to do maintenance to clean up the AC units and get them maintained.

    I used them this morning after the AC stopped working last night. I texted them at 730 AM and they were out here at 9 AM. Finished by 915 with a reasonable cost and fully explained. Very professional, clean, timely. CAS comes highly recommended in our neighborhood, I can see why.

    “Great Experience”
    I have nothing but good things to say about my experience with Chad and CAS Air Conditioning & Heating. Chad was able to come same day on the weekend to help fix my air conditioning. He took time to explain the full system, what was going wrong, and what he recommended. He even gave me advice on how he would size the system in the future when it needed to be replaced.

    Lastly, the prices he charges are very fair. Of all the people I have hired over the years CAS is one I would not hesitate to call again.

    “Friendly and Respectful”
    We were needing to replace a 15 year old a/c and furnace system before it completely broke down on us. Chad with CAS came by and gave us a quote. We got quotes from several companies, but got the best price and felt most comfortable with CAS. On the day of the replacement, the guys laid down drop cloths through the house to the attic ladder which is in a bad location in a hallway. Within 3 hours, the old system was removed and the new system was installed and tested. We couldn't be happier with the service CAS provided! Thank you guys!

    “Kind and Prompt”
    Chad was awesome. I really appreciate the service of a company that tells you the truth about what you need and does not needlessly try to up sell you. He came out, assessed what we needed, gave us a new filter and did not even charge us for his time! I am now a lifetime customer and advocate for CAS Air Conditioning!
