  • Charles McDuffee Co. Heating & Air Conditioning

    "Charles McDuffee Co. installed a new furnace for us about five years ago, so when we needed a new A/C unit this year, we knew exactly who to call! Mike and Travis both were friendly, professional, knowledgeable, and respectful of me and my home. They answered every question, worked quickly and efficiently, and completely cleaned up after themselves. I am a very satisfied customer!"

  • Charles McDuffee Co. Heating & Air Conditioning

    "We started using Charles McDuffee Heating & AC Co. about 20 years ago when we had a devastating flood in our town. Needless to say, our furnace and AC were ruined. When we called them for service, they were able to come to our assistance very quickly. We have been using them for all of our heating and AC needs since then. We are always very satisfied with their excellent service. Every spring and fall we get our units serviced. Just last week we had our routine service done by Matt, who was very pleasant and knowledgeable. Upon entering our house, he asked if we had any questions and then went about doing his work. When he was finished, he explained what he had done and again asked if we had any questions or concerns. As in previous visits, we were very satisfied and highly recommend them for all of your heating and AC needs."

    "Steve, Matt and Mike came over today to install a new furnace. They were on time and very professional. They were very careful moving the new furnace in and the old furnace out and completed the installation in a professional manner. After the installation, they cleaned up the work area completely and did an excellent job describing the operation and functionality of our new furnace. They were very dog friendly to our Pug which insisted on assisting them during the installation. We are already repeat customers and will definitely use Charles McDuffee for any future Heating and/or. Cooling issues"
