Anthony was very professional and communicative. He was easy to work with in setting up my hear pump installation project. I really appreciated the fact that he wasn't pushing a "hard sell" as some representatives from other companies did. When I had questions an needed quote options he was super-responsive and helpful. Great experience!When Carson, Isaiah, and Israel came your to perform the work, they were punctual, friendly, and respectful. When I expressed concerns or had questions, they addressed them immediately and effectively. Their work was outstanding, the job looks great and the system works well. I have already recommended Guthrie & Sons to other people.Thanks, again, for everything.

We’ve worked with a few Heating and Air company’s in the past at this was far and away the best we’ve worked with.

The removal of the old direct Heating and ducting went without a hitch. The installation of the new air conditioning and heating unit went very smoothly and I was impressed with every one of the workers. They were friendly and very knowledgeable. They were well equipped to deal with any process problems. I give five stars for this group.As part of the installation contract, Guthrie and Sons sent a worker named Wayne to replace the filter and check our air conditioning condenser. He was friendly and knowledgeable and even slipped on the covers over his shoes as he came through the house. The work was performed very quickly. Another five star performance by Guthrie and Sons.Zack visited today for yearly maintenance. Filter changed out and the unit is working optimally. We'll done.Daniel, this morning, replaced the filter and verified the furnace is in working order and providing proper heat throughout our home. Another skilled and friendly 5 star visit.

Your technician, Jonathan Santana was awesome. My husband was not home and Jonathan was very understanding. Even though there was a mix up with the service connection from Rheem, Jonathan assisted without hesitation. His help made my follow up conversation with Rheem much more productive. Please thank Jonathan for me.Best regards, Lisa
