What Our Customers Are Saying

  • Pat Suchan

    I couldn’t have been more happy when technician Hunter came to our home on a very cold night when the furnace went out. He was on call and it was late. Hunter was at our home in an extremely short time frame. He was very professional, knowledgeable, and informative. He had the furnace working in no time and also offered to show. me what the problem was. That was very important to me.

    Unfortunately, a couple weeks later the fireplace quite working. Technician, Jessie, came this time. He also was extremely prompt in arriving according to the time frame we discussed. Jessie was also extremely professional, knowledgeable and informative. The problem was tricky to fix but Jessie got it up and running. He gave me a wealth of information that was very helpful.

    I would recommend Robert Gibb & Sons to anyone. I couldn’t have been more pleased with their professionalism, knowledge and how accommodating they were.

  • Michelle Kaspari

    I was very happy with the friendly, courteous, and professional service I received from Robert Gibb & Sons when Technician Bob Wagner did a fall tune-up on my furnace last week. I was especially appreciative when he and the office staff were able to adapt to a last minute schedule change. A small part will need to be replaced on my furnace and I look forward to continued great service from Bob and the entire Robert Gibb & Sons team!

  • Ken Mikula

    We called for our yearly checkup for our furnace. Travis and his trainee arrived at the appointed time. They were very social an courteous. They were very knowledgeable about the furnace. The service was completed quickly and efficiently. We will continue to call Robert Gibb & Son for services.

  • John Moen

    Bob Wagner was very good. He was personable and answered our questions. It was a good experience and we are very satisfied. Everything is working great. Thank you! 👍

  • Josh Anderson

    I recently worked with Job Ebsen on having a garage heater installed. He came over and let me know all my options, along with info on heater size suitable for my garage. He had an estimate to me the same day and was able to schedule the work to be done the following week. They did a great job with the installation, even putting a covering over the gas line on the outside of the house to make it look better. I would definitely call Jon again for future work!
