Thanks to Russ and his crew from Hoock's Heating and Cooling, they did a fabulous and clean install.... The office staff is very friendly to deal with. I couldn't be happier.... Thank you very much... ??

The install went well. Russ' supervision, and the crew did a good job. Rick was very careful on the inside and very attentive to the care of installing the unit... offering to clean and take care of newly painted walls. Alex took greate care outside installing the unit. I recognized that he has a wonderful demeanor in teaching... explaining the process in a clear and informative manner to Riley!

Exceeded our expectations. They were knowledgeable and efficient. They seemed to care about the job they were doing. Rick* was patient and thorough when explaining the work that had been done and how to use the thermostat. Highly recommend!

I'm so glad I went with Hoocks Heating and Cooling. I got quotes from five different companies, but Hoocks really stood out. Russ went above and beyond to answer all my questions, listen to my concerns, and make sure I felt confident in my decision. He made the whole process smooth from the start.

Rick and Alex did a fantastic job with the installation. They were professional, friendly, and took the time to walk me through everything. Their work was top quality, and they made sure I understood what was happening every step of the way.

I’m so thankful to have found a company I can trust. No more stressing about who to call for HVAC work in the future. I highly recommend Hoocks to anyone looking for honest, reliable service.

Scott Frazier on Hoock's Heating & Cooling

First let me express how thankful I am that I called Hoock’s Heating and Cooling. I wanted a mini split for my garage.So I called and scheduled 3 companies to give me bids for the job. My wife and I do appreciate the aesthetic part of things I may ad. I met with all three representatives and expressed what we wanted and how we wanted it. Russ the owner of Hoock’s was very accommodating to our needs-the other two salesmen made excuses on why they couldn’t do the install the way that we wanted. All that I expressed to all three parties was that we just got new siding and so we wanted a minimum footprint on the outside of our home of conduit so that it would be aesthetically pleasing. Basically, looking for the least penetration of our home possible. Russ was the only one that stated” yes he could do it that way, no problem”.I did realize that it was gonna be more work for them because it would require 2 trips. The other two shot down what we wanted for various reasons. Russ got the bid to us first, and we committed before we even got the other two bids. Ironically, after the fact, his bid was the best and included the best equipment. The installation process went seamlessly, and we are very, very pleased with the final results. Russ and his employees are very professional, and you can tell that Russ is very detail oriented. And his employees reflect that in their workmanship. I highly recommend Hoock’s Heating and Cooling. If we ever needed any other work, we would not hesitate to call them. We’re very excited that we can heat and cool our garage on demand as needed. so if you’re thinking about having some work done, I recommend that you at least contact Russ-Rest assured you will not regret it.
